Goodbye, La Niña? Eric Snodgrass Dissects What the Shift Means for Weather This Spring and Summer

Fri, 14 Mar 2025 21:12:50 GMT

La Niña is weakening, and the National Oceanic and Atmospheric Association (NOAA) expects neutral conditions to develop in the next month . But even with La Niña fading, meteorologists are still concerned about drought this spring and summer.

NOAA this week said forecasters expect ENSO-neutral conditions to develop in the next month and persist through the Northern Hemisphere’s summer. According to NOAA, La Niña’s signature is cooler-than-average surface water in the east-central tropical Pacific, stronger-than-average trade winds, and drier conditions over the central Pacific.

ENSO-neutral means conditions could be close to average, but Eric Snodgrass, Nutrien’s principal atmospheric scientist, says that doesn’t mean the weather will be normal this spring and summer.

“I do expect changes,” Snodgrass says. “Think about it like this: The previous winter was an El Niño winter, and it was very mild and very wet. So, we got into spring ’24 with tons of moisture. I mean, Iowa, Minnesota and South Dakota flooded out. Then we had this incredibly dry fall as the La Niña began, and it reached a peak twice. It actually hit a peak in December, and then a secondary peak about a month later at the end of January. It’s been fading ever since. The big question is, as we go into neutral conditions for this upcoming growing season, is it going to be one that paints a picture of precipitation extremes? Did it leave us with any sort of kind of problems from winter that are carrying over?”

Snodgrass says the severe weather outbreaks on Friday, that brought high winds, dust storms and wildfire warnings across the Plains, is a reminder how dry it is in the Southwest.

“We’ve got major pockets of the country that are still dealing with some pretty big drought conditions. It is fading, and that is a signal we have to pay attention to,” Snodgrass says.

USDA meteorologist Brad Rippey is also concerned about what impact the shifting pattern will have on farmers this spring. But it’s not just the dryness. It’s also the fact areas are getting inundated with rains that could pose problems.

“With this stormy weather pattern in place, that is going to create some difficulty for spring field work in some areas. It looks like the primary storm track may be through parts of the middle of the country extending into the lower Midwest and eventually the interior northeast. That is one area where we already have fairly wet conditions,” Rippey says.

How sea surface temperatures in the Niño-3.4 region of the tropical Pacific changed over the course of all La Niña events since 1950 (gray lines) and 2024-25 (black line). This shows the traditional calculation for Niño-3.4, the monthly temperature compared to the most recent 30-year average (1991–2020 for the 2024 line). By this measure, the La Niña threshold was crossed in December 2024, but La Niña remains weak.

La Niñas and El Niños Are Strongest in the Winter
Snodgrass points out La Niñas and El Niños are always strongest in Northern Hemisphere’s winter, which means they fade in spring and summer.

While La Niña-like conditions were a trademark in late fall, we didn’t reach the official definition of La Niña until January.

“The atmosphere way back in November was already treating our winter timeframe like a La Niña,” Snodgrass says. So, we were getting the influences of it as it comes in and goes out. And now the question is, what’s it going to do?”

February 2025 sea surface temperature compared to the 1985-1993 average. The surface of the east-central tropical Pacific is slightly below average temperature, but much of the global ocean remains warmer than average.

“This is a great map to look at,” Snodgrass says, referencing the map above. “If you focus right in the middle, you see the large area of the cooler colors. Our line is now shifting to the central and West Pacific and behind it over by South America. All of the warmer water is beginning to emerge. And that’s what’s killing it because there’s a trade wind across that area from the east to the west. We’re going to watch this fade carefully during the spring. But the question is: Do we get winter’s leftovers?”

What Fueled the Dryness This Winter?
During the winter, Snodgrass points out there was no subtropical jet. That’s what fueled drought in the Southwest and Northwest.

“I’m actually kind of worried about the beginning of April having another shot at cold air after what we’ve been experiencing in March, which has been so very, very mild. Then you say, well, we’ve had so much dry air in place. Are we still worried about more dry air coming back? To be honest, these big storm systems coming through the central U.S., if we could get four, maybe five more of those by early April, we’re going to hate it. It’s nasty weather. It’s not fun, and it’s dangerous, but it returns moisture. That could be part of the mix of things, including the fading of La Niña that could help bring us away from these major early season drought risk scenarios.”

55% of corn production, 46% of soybean production, 33% of the cotton growing area and 27% of the winter wheat production are currently experiencing drought.

Growing Drought Concerns
What if it doesn’t? What if we don’t see more of this severe weather hit the Southwest and Plains, and moisture remains absent as we get into the height of spring? Well, the area will enter into the height of the growing season dry and reduce their chances of seeing moisture this summer.

“That’s a box we check every spring,” Snodgrass says. “If the drought monitor saw a reduction in drought over winter, then that gives us a different look for spring. But what we see here is two-thirds of the country in some stage of drought, including the abnormally dry category. But it’s the epicenters of drought that are so concerning. Look at the Western Corn Belt. Look at the Southwest. We just wonder if that funnels into the Mississippi Valley as we go forward.”

At the same time some areas are seeing drought, Kentucky, southern Indiana, southern Illinois, Tennessee, Arkansas and the boot heel of Missouri are all experiencing heavy rains and flooding.

“By May 11, I want to know what the drought monitor map looks like. If it looks no different, then I’m going to be sounding alarms going into summer with concerns this will start to creep and move because as soon as we get into the summer weather, all we get is convective storms pop off. And what do they do? They just locally deliver rain - not big broad swaths of it,” Snodgrass says.

Tale of Two Weather Scenarios
He says the forecast leading up to May 11 is a tale of two weather patterns, with the Mississippi River being the dividing line for moisture.

“If you are along it and east of it, I think we’re going to have tight windows to plant. You could include a little bit more of Missouri, Iowa and Minnesota in that as well,” Snodgrass says. “I think we’re going to see repeated storm systems. The best moisture is east. It keeps avoiding that southern plains area.”

What to Watch: Where the Storm Chasers End Up
Snodgrass says if storm chasers are busying chasing severe weather across the Ohio Valley, the mid-south and the southeast, but not in Kansas and the Plains, that’s a key indicator there’s a problem with the moisture getting back into the plains.

“If it’s not there by the time we start June, it’s very difficult to rely on the atmosphere to return it once you get into the summer months if you live in the central plains, which is where they could build from,” he adds.

Ag Meterologists Worry More Drought Lies Ahead For Spring

'Stay Tuned, We'll Be Right Back With Your Forecast'

Sat, 01 Feb 2025 15:02:27 GMT

What if you could know the timing of significant weather events for your area during the next six months with 91% accuracy?

Now you can, according to Gary Lezak, a former meteorologist with KSHB-TV in Kansas City turned weather entrepreneur.

Lezak’s business, Weather 20/20, provides weather-based data analytics on a global basis to its customers, who range from farmers to retailers to general consumers.

Eighty Years In The Making
Lezak learned in the mid-1980s that a weather cycle exists, an insight he attributes to Jerome Namais, who first addressed the concept in the 1940s. Namais, a renowned American meteorologist, was Chief of the United States Weather Bureau’s Extended Forecast Section in Washington, D.C. from 1941 to 1971.

“What it’s all about is the weather pattern above us – the river of air that goes across North America through the westerly belt, across to Europe, Asia, and then back around across the Pacific. That jet stream flow, that river of air above us, has an order to it,” Lezak told Andrew McCrea, host of the Farming The Countryside podcast, during a recent conversation.

For the next 20 years Lezak continued to study the weather cycling concept, refining what he learned as he went along.

By the early 2000s, Lezak was blogging about what he had learned, eventually calling the concept he developed the Lezak Recurring Cycle (LRC). He founded Weather 20/20 in 2008.

“The LRC is all about the cycle,” Lezak says. “After many years of practicing it, 20 to 30 years of using it, we are able to predict when and where and a little bit of the what,” with regard to weather, he told McCrea.

The core tenet of the LRC is that a unique weather pattern establishes itself every year. It starts to set up in early October, with develpment continuing through early January. By then, Lezak says the pattern can be identified and predictions of every day’s weather around the world can be produced.

Based on the LRC, Lezak says he can predict with a 91% accuracy level when and where there will be major weather events – from snowstorms to hurricanes to droughts – for the next seven to eight months in the U.S.

“That (timing) is the sweet spot of the LRC and fits agriculture perfectly,” Lezak says.

He adds that Mother Nature still creates weather disruptions he can’t predict 9% of the time, based on influences such as El Nino, La Nina and the Arctic Oscillation.

Lezak’s take on the accuracy of weather forecasts differs from what the National Oceanic and Atmospheric Administration (NOAA) reports, though an apples-to-apples comparison is not available.

The NOAA says a seven-day forecast can accurately predict the weather about 80 percent of the time and a five-day forecast can accurately predict the weather approximately 90 percent of the time. However, a 10-day—or longer—forecast is only right about half the time.

Agriculture Takes Notice
As Lezak was honing the development of the LRC in the early 2000s, fellow meteorologist, Dean Wysocki, then based in Nebraska, learned of it and reached out to Lezak for more details.

Wysocki started using the information he learned during his broadcasts, noting that Nebraska farmers were hungry for more accurate weather insights and predictions.

“I’ll tell you what, it’s a game changer. That’s the easiest way to put it,” says Wysocki, who joined Lezak on the podcast.

Wysocki, now based in Fargo, N.D., got LRC certified and began telling farmers in the Dakotas and Minnesota about its benefits.

“It’s a major piece of long-term weather forecasting, and the accuracy on it has just been amazing,” Wysocki says. “We’ve signed up between about 50 to 100 in our ag community and we’ve got nothing but positive feedback. Is it 100% correct? No, nothing is, but it’s a great tool to have on your tool belt.”

The Weather Outlook Ahead
During the conversation with McCrea, Lezak and Wysocki shared some of their weather predictions for late winter and early spring 2025, based on information the LRC has provided. Here are three of their predictions:

1. Lezak says a La Nina, which is the cooling of the tropical Pacific Ocean, has a grip currently on parts of the western and upper Corn Belt areas, but he expects that to ease up.

“That grip that it has tends to shift precipitation patterns to the eastern Corn Belt. That’s not good for Nebraska, Kansas, Iowa, Minnesota, North Dakota and South Dakota,” Lezak says. “It shifts precipitation patterns to the East, but that grip we think is going to be let loose by March.”

2. Wysocki says he foresees a wetter spring, in March and April, for most of the Dakotas.

“We’ll get our moisture that we need in March and more than likely into the first part of April, and that should be good for planting season,” he says. “I’m still concerned about the western Dakotas into areas of Montana and Wyoming, worried that they’ll remain dry.”

3. With regard to drought, Lezak encourages farmers to keep an eye on the weekly U.S. Drought Monitor, as he says droughts are constantly either shrinking or expanding.

“It appears that over the last year or so that areas of drought, as we look at the entire nation, have begun to decrease,” he says. “This one has been shrinking for weeks, and that is a good sign. The likelihood of that trend continuing is high.”

Wysocki and Lezak offered additional weather insights during their conversation with McCrea. You can hear more of those specifics on the podcast, available here:

2025 Weather: Drought and Root Zone Maps Signal Dryness Ahead

Mon, 30 Dec 2024 19:25:59 GMT

As 2024 comes to an end, roughly 70% of the nation is experiencing some level of drought and dryness.

Recent precipitation led to small improvements in parts of Oklahoma and Arkansas northeast to the Central Appalachians. Since its peak in September, the drought affecting the Central Appalachians and Upper Ohio Valley has steadily improved.

In the northeast, near to above-normal precipitation in the past 30 days means drought conditions have improved.

Across the Southeast, Lower Mississippi Valley and Texas, precipitation deficits continue to increase.

December is typically a drier time of year for the Upper Midwest and Northern to Central Great Plains.

Since the beginning of October, precipitation has generally averaged below normal across the Central Rockies, Great Basin, Southwest and southern California.

Northwest California and much of the Pacific Northwest have experienced wetter-than-normal conditions.

When it comes to severe or extreme drought, parts of the Northern Plains, the Southwest and the Tennessee Valley fall in those categories. Portions of the Midwest are now considered D1/moderate drought, and one-fifth of Indiana is in D2/severe drought.

Looking at various crop production areas, the following are currently affected by drought:

Barley, 35%
Corn, 54%
Cotton, 18%
Durum wheat, 70%
Peanut, 29%
Rice, 15%
Sorghum, 31%
Soybean, 47%
Spring wheat, 33%
Sugarbeet, 48%
Sunflower, 78%
Winter wheat, 27%

While the drought monitor looks longer term, NASA’s root zone soil moisture map shows just how dry it is in the top 3’ of soil across the Corn Belt and Southwest.

Eric Snodgrass, principal atmospheric scientist at Conduit Ag, says the current La Nina is weak and fading, but it continues to influence weather patterns, which is sending warning signs for spring.

Snodgrass says we’re missing one important component in the atmosphere — the subtropical jet stream, which comes from Hawaii.

“We have the polar jet in place that will drive really cold air into the New Year, especially into the eastern two-thirds of the country, really cold air for probably a while,” Snodgrass says. “Until we crank the jet stream out of the Southwest, it’s hard to return a lot of moisture and break the fear of drought spreading from Mexico or from the western High Plains, which I think is where it’s going to come from next year.”

Snodgrass is worried about drought for two reasons:

Drought conditions are developing in Mexico, the western Plains, the High Plains and all the way up to Canada.
In six of the past 10 years with a really dry fall, the spring to follow was also dry. That causes concern for a big chunk of the Plains and into the Midwest.

Snodgrass says the best opportunity for a pattern shift would be if La Nina breaks down in the next few weeks and transitions to a more neutral pattern heading into spring.

Hope For Drought-Stricken Land? Your Winter Weather Outlook

Mon, 28 Oct 2024 20:24:17 GMT

What is it you remember from last year’s winter? Maybe it was when the wind chill in Kansas City brought temperatures down to -30°F and Patrick Mahomes’ helmet shattered in the middle of a playoff game. A more accurate representation of the season, though, is probably Wisconsin’s snowmobile industry dubbing the season a “lost winter” from the lack of snowfall.

Regardless of how we remember it, last year’s winter was incredibly mild, with temperatures well above normal and snowfall almost nonexistent. But according to Eric Snodgrass, senior science fellow at Nutrien Ag Solutions, the consensus is that the months ahead are going to look a lot different.

“We didn’t really have a winter last year,” Snodgrass says. “This year, we have a better chance of a storm track coming through the “I” states and out through the Ohio Valley toward the northeast. So, the forecast is a little wetter there with periods of colder air. It doesn’t mean it will get cold, stay cold and not stop snowing, but it’s certainly going to be different than a year ago.”

That’s because this winter brings about a 75% chance for La Niña to develop, which is when the trade winds across the equatorial Pacific are strong. With La Niña in the forecast, the National Oceanic and Atmospheric Administration (NOAA) is predicting wet conditions in the north and dry, warm weather in the south.

The 2024-2025 U.S. Winter Outlook map for temperature shows the greatest chances for cooler-than-average conditions in the Pacific Northwest of the U.S.

(NOAA)

USDA meteorologist Brad Rippey says La Niña can also bring chances for extreme cold events.

“Not every La Niña is like this, but I will say two prime examples were in 1989 and 2021 — that latter outbreak was when Texas pretty much lost power,” Rippey says.

Drought Dangers
With dry conditions in the forecast, Snodgrass says the big story this winter will be whether or not there will be enough moisture to work against the drought that has been building.

“The best winters for agriculture are the ones we hate and remember as being terrible — we get good, hard freezes and plenty of moisture comes in,” Snodgrass says. “If we don’t see that, we get into a situation where we become very dependent on spring rains and may have a conversation about 2025 drought risk.”

The 2024-2025 U.S. Winter Outlook map for precipitation shows wetter-than-average conditions are most likely across the Great Lakes region of the U.S.. Drier-than-average conditions are forecast for parts of the U.S. Gulf Coast.

(NOAA)

Snodgrass explains drought is often a multiseason effect, and Rippey says this one has been building since June.

“There’s been a four-fold increase in drought to now affecting about 50% of the country,” Rippey says. “That was great for summer crops, dry down and harvesting, but now the problem is what will happen with winter wheat, cover crops, pastures and range land.”

While much of the north will have the opportunity for relief from this growing drought, that likely won’t be the case in the south.

“We are expecting a generally warmer- and drier-than-normal winter across the entire southern tier of the United States, reaching all the way from Southern California to the middle and southern Atlantic coast. That does include important winter wheat production areas into the Southern Great Plains,” Rippey says. “There’s not much reserve right now in terms of soil moisture, and this could amplify already existing dry conditions.”

That brings concern for river transportation as the bump in water levels that came from Hurricanes Milton and Helene has worked its way through the system now.

“Historically, those levels tend to bottom out around January at the latest,” Rippey says. “We’re probably talking about a few more months of low water issues, and then you start to turn a corner around February because plants don’t use as much water during the winter.”

Timing Will Be Everything
Because winter is technically the country’s dry season, it won’t be easy to break drought in the months ahead. For the wet forecast in the north to make a difference, Rippey says it will all come down to timing.

“It’s important to start getting moisture before it gets too cold,” Rippey explains. “When you go into a cool season like this with limited soil moisture, if the cold air comes in too quickly, you freeze the soils before you get moisture, which can limit the absorption of rain and snow into those soils.”

The timing of when La Niña really starts to take effect will be important as well.

“December is going to be the month where we test if this La Niña really has what it takes to give us the things we expect,” Snodgrass says. “Normally, La Niñas peak around Christmas, and then they start to fade. If we miss that opportunity, we will watch all of the sub-seasonal things and hope they can deliver good winter weather to knock out the risk of drought going into 2025.”

But even with a few “drought risk” boxes being checked, it’s still too soon to speculate or worry about what next year’s growing season will look like.

“2022 had major fall drought, and then what happened? It rained in July, didn’t get terribly hot, and we had a decent crop. Indiana had one of its best crops ever in 2023, even though it was so dry in spring,” Snodgrass says. “We have to remember that the crop has many ways by which to stay alive and do well, and we’ve engineered that seed to be better performing even when there is some stress. We can’t make big, broad assumptions that 2025 is going to be a year of substantial drought risk that destroys yield.”

More Wind, Rain and Hail Likely Ahead in June

Wed, 29 May 2024 20:14:22 GMT

The long line of severe storms that swept across the Midwest on Friday – from parts of Nebraska, through Iowa and into Illinois – has been officially classified a derecho by the Storm Prediction Center.

The Center classifies derechos as a wind damage swath that “extends more than 240 miles and has wind gusts of at least 58 mph or greater along most of the length of the storm’s path.”

It signaled the start of what became a severe weather weekend and a 2024 Memorial Day, with dozens of reports of strong winds, rain or hail hitting many parts of the U.S.

“We have obviously seen an absolutely, astronomically high number of severe weather reports over the last month,” says Michael Clark, chief meteorologist for BAMWX.com.

Clark says during May alone, there have been 469 tornadoes, 3,475 severe wind events and 1,640 severe hail events in the U.S. The number of storms reported is one of the highest for the month of May, if not the highest, since 2011. See You Can Now Blame El Niño and La Niña For the Extreme Weather Outbreaks, Planting Delays This Spring

“I’m looking at the map right now, and it’s almost as if every state east of the Rockies has reported a tornado during the month somewhere,” he says. “It’s kind of hard to wrap your head around how much there’s been.”

A Tough Transition Is Underway
While the number of storms this month has been unusually high, their occurrence has been expected meteorologists say, as the country transitions away from an El Niño into a La Niña.

“In spring, whenever you see these transitions, severe weather is amplified quite a bit,” Clark says.

According to the National Centers for Environmental Prediction, there is a 49% chance La Niña develops between June and August, and a 69% likelihood it will be in place sometime between July and September.

Clark and his meteorologist colleague Bret Walts told AgriTalk Host Chip Flory that they are predicting La Niña will be in place sooner than later – likely by July.

“I think that the atmosphere has already been trying to respond to that,” Walts says. “We’ve certainly seen it with this severe weather.”

More Rough Weather Ahead This Summer
Walts believes high winds and big rainstorms will continue throughout late spring and into the summer months. See Iowa Crews Search For Survivors After Deadly Tornadoes

“I’m concerned that as the heat ramps up later on into June and July that we could get more of these derechos going through,” Walts says.

In addition, Walts and Clark are concerned significant heat domes will occur over the Corn Belt and rain events will slow significantly as the second half of the growing season gets underway. See Expect a Hotter Than Normal Summer This Year

“When La Niña sets in, I am under the impression that in the later part of the growing season the moisture will be potentially shutting off,” Clark says. “This happens in big hurricane seasons where that ridge of heat sets up over the northern U.S., over the Great Lakes. It steers hurricanes into the Gulf of Mexico, but it shuts off precipitation in the Corn Belt.

“That’s a concern I have this year,” Clark adds. “These very wet springs with a lot of moisture going into La Niñas historically don’t really turn out to be very friendly the second half of summer.”

Winter Weather: Find Out What's in Store for Agriculture

Wed, 18 Oct 2023 18:52:06 GMT

The upcoming winter is shaping up to look a bit different than the past several years. The shift to a different weather pattern, El Nino, is in the works – resulting in a very strong subtropical jet stream and a weakened polar jet stream.

Brad Rippey, USDA meteorologist, shares the predictable changes to North American weather those involved in the agriculture industry should be on the lookout for.

Northern Weather Will Be Drier
One of the common changes Rippey shares is unusually mild weather across the northern tier of the U.S. The mild weather is a result of the weak polar jet stream and affects areas stretching all the way from the Pacific Northwest to New England.

“That of course has implications for winter crops,” Rippey says. You don’t get as much establishment of a snow cover, but at the same time, you don’t have a whole lot of cold weather to deal with and there’s less concern for winter kill. So, it’s kind of a tradeoff there.”

(Farm Journal)

Along with the milder temperatures, northern states are also predicted to see drier conditions this winter.

An outlook published by NOAA in late September shows between a 33 to 50% chance of below average precipitation for a portion of the northern U.S between November and March. The areas NOAA expects the largest impact are the Pacific Northwest and Great Lakes region.

(Farm Journal)

The dry, warm conditions have the potential to make this planting season an early one.

“It all depends on how the snow falls, but generally speaking, soil temperatures will likely not be as cold as they were in the spring of 2023,” Rippey says. “Given the mild, dry forecast, there may be a fairly quick planting season in the north for spring 2024.”

The Story for Southern States is Much Different
“The enhanced subtropical jet stream tends to bring stronger storms across the southern tier of the United States,” Rippey says. “Sometimes that affects Southern California but it’s more likely along the Gulf Coast and southern Atlantic coast.”

NOAA’s predication maps show the highest probability of above average rainfall – 50 to 60% – for states along the Gulf and southern Atlantic coasts.

The increased precipitation in those areas is something Rippey says could help with low water levels from the summer’s drought.

“As we get deeper into autumn and the heart of winter, the odds most definitely increase we will see wetter conditions in places like Arkansas, Louisiana and Mississippi where we’ve got not only low water levels impacting navigation, but also the saltwater intrusion from the Gulf,” he says. “It may take a while but eventually as the winter proceeds, we should see relief especially in the southern part of the basin.”

The Wild Card to Watch For
A less clear aspect for this winter’s forecast could be due to elevated oceanic temperatures, which have the potential to keep global temperatures high through the winter and into 2024.

The high oceanic temperatures produce blocking high pressure systems, which Rippey says can be blamed for Canada’s wildfire season and recent heat waves and fires in Europe.

“If some of the oceanic temperatures continue to induce weird blocking patterns, that can lead to extremes like heat, cold, droughts and floods that’s generally independent from El Nino,” he says.

Effects on South American Production
El Nino has different implications for growers in South America.

Key production agriculture areas such as southern Brazil and Argentina are just moving into their spring growing season and the El Nino weather patterns are expected to create more favorable conditions for their crops than La Nina.

“From a crop production standpoint, I would expect improving conditions in some of the areas that have been impacted by drought over the last few years,” Rippey says. “As you move northward into the Amazon basin, El Nino can trigger drought. That’s a concern from an ecological standpoint and that drought often extends into places like Mexico and the Caribbean for as long as El Nino persists.”

Storm Could Bring 4 Inches Of Liquid To Already Saturated Fields

Fri, 20 Nov 2020 05:23:49 GMT

Farmers in Nebraska, South Dakota, Iowa and Minnesota are bracing for yet another monster storm. This time, meteorologists expect up to 4 inches of moisture in various forms to pummel already saturated fields, many of which are in flooded regions.

“I have some customers out in South Dakota who are reporting almost a foot of snow already,” Ed Vallee of Empire Weather told AgriTalk host Chip Flory. “They’re asking when is this thing going to wind down? Unfortunately, this thing is just developing down on the plains of Colorado, and it’s going to be moving eastward and ramping up.”

According to Vallee, this first band of storms currently moving into Northeastern Iowa has produced more precipitation than meteorologists expected.

“It’s one of those situations where as it starts developing, we do our best to kind of tweak and make the forecast as good as it can be, but I think later tonight and especially late tonight and into Thursday morning we’re going to be dealing with some pretty heavy snowfall in the same areas that got hit with the [last round of flooding].”

The storm won’t only produce snow, Vallee said it’s a dynamic storm and depending on location will likely produce different precipitation types ranging from wet snow, to dry snow and even rain. Severe weather is also a possibility.

“Anytime you get a storm this time of the year, you’re going to be dealing with a lot of different temperature variations over short distances. That’s kind of what fuels the storms to strengthen and ultimately provide a lot of threatening hazards,” he said. “I think as we continue to move on here the snow was very wet, dense especially during the day. But as we get into the nighttime hours, we’re going to feed in a little bit more cold air coming in from the north and that may actually allow the snow to dry out a little bit across South Dakota and portions of western Nebraska.”

This storm is likely to cause additional flooding.

“I think the moisture in this storm is really the takeaway,” he said. “We’re going to be dealing with two to four inches of liquid with this storm on top of the flooding we’ve seen over the last few weeks, so this is not a good situation for a lot of places.”

Vallee expects the storm to stick around through the end of the week and said it will likely peak first thing on Thursday. With the moisture comes a significant wind threat.

“It’s going to be a wide-reaching wind threat. Obviously where there’s snow falling, that’s the biggest concern because you toss wind and snow together that’s a power outage pretty quickly,” he said. “But even if you’re not seeing snow or even any precipitation here, we’re going to be dealing with these winds out of the South in those locations pretty much right through tonight and that’s going to be in that 40 to 60 mile an hour range. Which, even if you’re not getting two feet of snow, that’s obviously not welcome.”

When the storm pushes out of the Western Corn Belt on Thursday night and into the Ohio Valley, severe weather will be the biggest threat, according to Vallee.

“As we get into Friday, this should taper to only a few snow showers and then our focus is going to turn to clean up and then the blowing snow threat, especially across the areas that get hardest hit overnight today,” he said.

El Nino Coming Back?

Fri, 20 Nov 2020 05:12:06 GMT

(Bloomberg) -- La Nina is dead. Long live El Nino?

A weather pattern known as La Nina that has worsened drought conditions across the U.S. Great Plains has faded, according to the U.S. Climate Prediction Center. But it could be replaced late this year by one called El Nino, which often roils agriculture and energy markets around the world.

La Nina and El Nino are the terms used for fluctuations in ocean temperatures and atmosphere in the equatorial Pacific that can cause large-scale changes to the global climate. Conditions are now neutral, though the potential for El Nino has increased, according to the center in College Park, Maryland.

“La Nina is gone,” said Michelle L’Heureux, a forecaster at the center. “We did not issue an El Nino watch because the probabilities are still not that high, but we wanted to at least notify folks there is a possibility.”

The problem facing meteorologists is forecast models about El Nino and La Nina aren’t very good at this time of year. Many predictions about El Nino and La Nina made in the Northern Hemisphere’s spring have fizzled in the past, L’Heureux said. But La Nina probably won’t be coming back for a third year, and the chance of an El Nino forming between November and January is 49 percent, up from 48 percent last month.

El Ninos, which occur when the ocean warms and the atmosphere reacts, can bring torrential rains to parts of South America, depress winter storm tracks through the U.S. and -- if they arrive early enough -- cut the number of tropical storms and hurricanes in the Atlantic.

‘False Alarms’

“At this time of year the false alarms of some of these models is fairly high this has to be taken into consideration,” L’Heureux said, adding that it gets easier around July and August.

The last El Nino, one of the strongest on record, left farmers from Vietnam to Africa struggling with drought, triggered powerful Pacific typhoons and hurricanes and helped push the Earth into a series of its warmest years on record. There is a good pool of warm water across the Pacific, so if the atmosphere does edge toward El Nino “it has a good source to tap into,” L’Heureux said.

The La Nina that just ended probably did play a role in the drought across the lower Great Plains, which has damaged hard red winter wheat throughout the region, L’Heureux said. Almost 89 percent of Kansas is dealing with drought, while just under half of Texas and Oklahoma were also struggling as of May 1, according to the U.S. Drought Monitor in Lincoln, Nebraska.

Tuesday, the Australian Bureau of Meteorology also said the Pacific is in its neutral state and will probably remain that way into September.

A Week of Good Planting Weather in Store

Thu, 19 Nov 2020 03:04:10 GMT

Weekly BamWX.com forecast from Chief Forecaster Michael Clark

As advertised last week a significant warm up is near! Temps early next week will start to top out in the upper 70s and even 80s with a nice stretch of dry weather over the next seven days. New data in Tuesday morning showing temps to be much above normal next week with a bigger storm threat in the 9-10 day period across the heart of the grain belt. While this pattern is set to moderate overall the next few weeks we can still anticipate episodes of cooler than normal weather. Current thinking is that the May pattern could feature a roller coaster ride temp wise as we could be dealing with cooler risks at times especially in the grain belt regions. We will continue to update daily on Bamwx.com .

Ag Weather Outlook: Volatile With Rain and Snow

Thu, 19 Nov 2020 03:01:51 GMT

Weekly weather outlook from Michael Clark of BAMWX.com

The outlook into early to mid-April is a volatile one with ups and downs and plenty of rainfall on the table, especially for the eastern ag belt. Between now and the next two weeks we expect the pattern to be dominated by a strong Alaskan ridge. (-EPO) This will drive the cold you see in the outlook for this week and next, which means winter storms are not out of the question over the next two weeks.

Beyond week two we anticipate some of this blocking to subside, and with that will come some warmer risks especially across the southern and central tier of the ag belt.

Analogs and perhaps a favorable state of the MJO supports the idea of some warmth to build around April 7^th and beyond. With that being said, it’s possible the eastern ag belt will remain active during this time with heavy rainfall risks and some severe weather into weeks three and four. You can see from our outlooks over the next four weeks that they tell this story nicely.

La Nina Fades Away

Thu, 19 Nov 2020 03:00:55 GMT

(Bloomberg) -- The shortest La Nina in almost a decade has ended, just three months after it began.

Sea surface temperatures have warmed steadily since December and are now in the neutral range, Australia’s Bureau of Meteorology said in a statement on Tuesday. Most models indicate a neutral pattern will persist into the Southern Hemisphere autumn and winter, it said.

La Ninas happen when the Pacific’s surface cools and the atmosphere above it reacts, disrupting weather patterns around the world. The most recent event dried out fields from Kansas to Texas and parched soy crops in parts of Argentina. While the weak and short-lived La Nina had relatively little effect on Australian rainfall over the past summer, previous patterns have brought flooding rain to the country’s coal-mining regions and inundated farmland.

The U.S. last week said there’s a 62 percent chance the Pacific Ocean would return to a neutral phase between April and June. Researchers have detected warmer water building below the ocean’s surface, according to the Climate Prediction Center.

The latest La Nina was the shortest since 2008-09, according to the Bureau of Meteorology, citing records dating back to 1980. The Pacific Ocean slowly swings between three states, running from cold to normal to warm.

‘Moisture Opportunity’ Is On Its Way To The Plains

September was one of the driest months on record for parts of the Midwest, and October has continued the dry trend, said Chip Flory, host of AgriTalk, on Tuesday’s show. He asked guest John Homenuk of Empire Weather Consulting, what shut the moisture off in the middle of the country.

“We’ve had this ridge in place since September, which we’re fortunate didn’t happen in late July and August,” Homenuk told Flory. “We’ve kind of been in this really poor cycle for moisture for several weeks.”

Homenuk said parts of the U.S. have been in a fairly weak La Nina weather pattern, which he expects will “oscillate up and down a bit” throughout this fall and into the 2024-25 winter months.

However, Homenuk does anticipate some limited moisture will start to move back into Midwest weather forecasts soon.

“For instance, late this weekend and early next week, we have a moisture opportunity coming into the Plains,” he said. “A low-pressure system could spread out of the Intermountain West into the foothills, and eventually bring some moisture to places like the Texas Panhandle, Kansas and Nebraska. That’ll be the first system to come out, and there might even be some scattered showers across parts of the Midwest early next week.”

Meteorologists anticipate weather patterns will continue to lean toward more moisture as November gets underway.

“It’ll be a slow go of it, but the feeling is that we’re through the worst of the dryness now, and we’ll start working back gradually into a more normal pattern,” Homenuk said.

Looking Ahead To Next Spring

Flory asked what kind of weather pattern farmers can anticipate going into the 2025 cropping season.

“There is some indication already on models that we’re going to split up again, between a La Nina and El Nino,” Homenuk said. “Some of the indications stay near neutral, so not a La Nina or El Nino, and some of them start actually sending us back into El Nino by spring and summer of next year. I think we need to get through the next couple of months before we really have an inclination of where it’s going to go next year.”

Flory said he’s concerned, given the weather conditions this fall, that next spring will be a dry one.

“It’s kind of common to hear people say, ‘droughts don’t start in the year that they happen. They start in the fall before.’ And I think there’s more than a few producers out there that are concerned that this drought we’ve got in the middle of the country is going to continue on into the spring of next year,” Flory explained.

Homenuk said he believes if the U.S. transitions back to an El Nino weather pattern by spring, that should be generally viewed as a good thing.

“That would reintroduce some more moisture. If we stay neutral, or we stay in a weak La Nina into the spring, then I think those lingering drought concerns could make their way into the growing season in 2025,” he added.

Weather Outlook For South America

Flory asked what kind weather South America, Brazil and Argentina in particular, will see for its growing season.

“We’re kind of into this weak La Nina scenario,” Homenuk said. “What tends to happen down there in South America is you get a little bit of a mixed bag. So, it was a slow start over the last couple of weeks, but now we’re seeing a pattern change across central Brazil, essentially Mato Grosso southward, where there’s moisture coming into the forecast over the next several weeks.”

He added that the same could likely be said for northern Argentina.

“If you look at the next 15 to 30 days, the moisture forecast is actually pretty solid. They have some ground to make up, given how dry it was before. But I think these weak La Ninas tend to be OK in those regions. It is a kind of pattern indicating that there will be some moisture around it. I think they’ve avoided the worst-case scenario, which would have been a really strong La Nina developing.”
