Mid-March Heat Wave Shatters Records in the West — Is This a 2012-Style Setup?

Fri, 20 Mar 2026 17:02:52 GMT

A powerful and persistent heat wave is sweeping across the western United States, shattering temperature records and fueling growing concern among farmers and ranchers about what it could signal for the months ahead.

From the deserts of the Southwest to the inland Northwest, the scope and intensity of this early-season heat event is turning heads. More than 60 daily record highs have already been set, with temperatures reaching levels far more typical of late spring or even midsummer.

In Palm Springs, the mercury surged to a scorching 103°F. Phoenix hit its first 100°F day of the year — marking the earliest occurrence on record and breaking a longstanding record set in 1988. Meanwhile, Boise climbed to 80°F, the earliest date that threshold has been reached since record keeping began in 1875, and only the second time it has ever happened during winter.

For producers already navigating tight margins and dry pasture conditions, the question is immediate and pressing: With the current drought picture and early extreme heat, is this a similar setup to 2012?

A Stubborn Pattern Takes Hold

According to Brian Bledsoe of Brian Bledsoe Weather, the current heat wave is being driven by a dominant atmospheric feature that is effectively locking in warmth and shutting out precipitation.

“Well, the good thing about this time of year is that with the seasonal change that takes place, we usually see some weather variability take place along the way, instead of just getting locked into these things for just weeks on end,” Bledsoe explains. “And I think that’s an important thing to consider here. First of all, that I’m much happier that this is occurring now, if it has to occur — versus, say, in July or August, because we’ll see this thing break down eventually.”

He says the current setup isn’t brief in the short term, with the forecast map showing the high heat sticking around through at least early April.

“If we look at our forecast temperature anomalies right through April 1, you see that big orange and red blob over the West and the Southwest. And for that matter, across a large part of the country. This ridge is not just going to impact the West. I’s going to spread its way eastward,” Bledsoe explains.

That expansion of warmth could bring above-normal temperatures to regions that have not yet experienced much seasonal heat.

“It’s going to bring a substantial amount of warmth to some areas of the country that haven’t been necessarily all that warm,” Bledsoe says. “So we’re locked in this at least through the end of March.”

Heat and Dryness Go Hand in Hand

The same high-pressure ridge driving the heat is also suppressing precipitation — a combination that is particularly concerning for agriculture.

“Precipitation anomaly-wise, that’s also going to be kind of owing to what this ridge is about, which is just kind of blocking any big storms from coming in from the Pacific,” Bledsoe says. “So, wherever you’re seeing the brown, that is likely where we’re going to see drier-than-average conditions through the same time.”

Much of the Southwest, and the central and southern Great Plains, missed out on precipitation, and instead dealt with a dry, warm and windy week.

Why that’s so concerning is the latest U.S. Drought Monitor, which shows 41% of the nation’s corn production area is already in drought . For cotton, 89% is facing dry conditions. For cattle country, 54% of the current cattle inventory is experiencing drought.

This week’s drought picture reflects a sharp split across the country. While areas of the upper Midwest and East saw rain and snow, much of the Southwest, central and southern Plains, and parts of the western U.S. experienced a dry, warm and windy week, which worsened conditions.

Drought and abnormal dryness expanded or intensified across areas like South Dakota, Nebraska, southwest Kansas, southern Colorado, New Mexico, Arizona, Nevada and parts of Oregon that missed out on meaningful moisture. Overall, while some regions saw clear improvements, the lack of precipitation and ongoing moisture deficits continue to drive worsening conditions across a broad swath of the western and central U.S.

That lack of moisture, combined with unseasonable warmth, could accelerate soil moisture depletion and stress rangeland and early-planted crops. Still, Bledsoe emphasizes the calendar offers some reassurance.

“There is some potential for this to break down, though, I think, as we get into April,” he said. “And I think, as I mentioned, that is a very important thing to consider.”

Ocean Temperatures Play a Major Role

Beyond the immediate atmospheric setup, Bledsoe points to broader oceanic influences that are helping fuel the current pattern, but more particularly what’s happening in the eastern Pacific.

“The other element of this is what’s driving this in terms of heat right now, and it has a lot to do with the sea surface temperature anomalies situated off the west and southwest coast of the United States,” he says.

“If you look at those sea surface temperature anomalies there off the Baja, that is a lot warmer than average than we should be. And if you go just to the south of there, that’s the western tip of South America, and that’s where our budding El Niño event is taking place,” Bledsoe adds.

Sea surface temperatures tell the story for what summer could bring.

Those warmer waters are part of a larger pattern known as the Pacific Meridional Mode (PDO), which can have significant impacts on U.S. weather.

“There’s a lot of warmer-than-average water that’s right there in the East and the Northeast Pacific Ocean,” Bledsoe says. “And any time you see this signature right there, especially off the southwest coast of California, the Baja, western New Mexico — that is referred to as the positive phase of the Pacific Meridional Mode.”

He says the current setup bears some resemblance to patterns seen in recent years, including 2023, when a rapid transition from La Niña to El Niño coincided with widespread heat.

“One important reference that I want to kind of draw a comparison to here is the last time we had a really positive Pacific Meridional Mode,” Bledsoe says. “This is what happened in July and August of 2023. And remember, I’ve talked about this before, but 2023 was the last that we went from a La Niña to an El Niño in a pretty quick fashion. And we also had that positive phase of the Pacific Meridional Mode.”

The result then was widespread warmth across the West and into the southern Plains and Gulf Coast. However, precipitation outcomes were more mixed.

“You might say, well, did that necessarily reflect a dry summer too? Were the precipitation anomalies dry for that? For some areas, but not everybody,” Bledsoe says. “And I’m not saying that 2023 is exactly what this upcoming year is going to be. I’m just trying to draw some parallels here from where we might see some of these things take place.”

Not the Same As 2012

Bledsoe says the current weather pattern bears watching, but it’s important not to confuse it with the historic 2012 drought. One of the biggest differences is the large-scale atmospheric and oceanic setup. In 2012, the U.S. was working from a weak La Niña base, and a persistent ridge of high pressure locked in over the central Corn Belt, cutting off moisture and allowing heat to intensify week after week. That kind of feedback loop is what turned a hot pattern into a historic drought.

This year, the setup is fundamentally different.

“You can’t, from a sea surface temperature standpoint,” he says. “I’ve talked a lot about this on X. That same area of the ocean that I was just showing you just a little bit ago was a lot colder than average than where we are right now,” Bledsoe says. “So, there are different forces at work. When you get cooler-than-average sea surface temperatures off the west coast of North America, extended from the Baja all the way up to the Gulf of Alaska, a lot of times that is a very strong heat and drought signal for the center part of the country. And right now, that is the complete opposite.”

The transition into El Niño conditions tends to favor a more active storm track and can help keep systems moving across the country, rather than allowing a dominant, stationary ridge to take hold. Bledsoe points out while heat will still develop, especially in parts of the South and West, the overall pattern does not show the same prolonged, stagnant heat dome that defined 2012.

The current soil moisture levels and early-season precipitation are generally more favorable than they were heading into the 2012 growing season. Back then, much of the Corn Belt was already running dry before the worst of the summer heat even arrived, which allowed drought conditions to escalate rapidly. Today’s environment, while not without risk, starts from a less vulnerable position.

That said, Bledsoe cautions there are still areas to watch. While the central U.S. doesn’t appear poised for a 2012-style widespread drought, there are signals pointing toward heat and dryness across parts of Texas, the southern Plains and areas along the Gulf Coast. He notes a scenario where spring moisture gives way to drier summer conditions that could set the stage for localized flash drought concerns by mid-to-late summer.

Overall, Bledsoe says the takeaway is that while 2012 remains a benchmark for extreme heat and drought, the current setup does not mirror the same atmospheric drivers. The pattern this year appears more dynamic, with regional risks rather than a single, dominant, all-encompassing drought signal across the heart of the country.

A Critical Window Ahead

For now, the early-season timing of this heat wave may ultimately limit its long-term damage, but it does not eliminate risk.

“We obviously have to prepare for it,” Bledsoe says. “But the good thing about something occurring right now is that it’s transient. It will get out of here.”

He adds: “And I’m sure we’re going to see something that is probably more akin to that spring change soon.”

Until then, producers across the West, and increasingly across the central U.S., will be watching forecasts closely, balancing cautious optimism with the reality that the 2026 growing season is already off to an unusually hot start.

The El Niño Effect: Is El Niño to Blame for the Historic Heat and Drought that Gripped the U.S. in 2023?

Tue, 02 Jan 2024 22:10:01 GMT

2023 was a year full of weather impacts on crops and livestock. From the intense heat in the South to the drought that parked itself across the South and Midwest, USDA meteorologist Brad Rippey says those are the two weather events that stole headlines this past year.

“When we look back at 2023, I’m actually going to break heat and drought into two separate categories,” says Rippey. “Really, when you look at the extreme heat this past year, it was focused across the deep South from Arizona to Florida, and pretty much everywhere in between. And that was certainly a huge weather story that affected parts of the cotton belt.”

From wiping out a large part of the cotton crop in west Texas to hitting sugar cane production in Louisiana, Rippey says nearly the entire deep South saw impacts of the year’s extreme heat.

“Of course, that came with drought in many cases. But when you look at these overall temperatures, the hottest summer on record and a lot of hottest months on record, that was a big story in the deep South,” says Rippey.

While other parts of the U.S. still had drought, in some areas it didn’t pack as big of a punch because it came without the heat. That was the case in much of the Corn Belt. The drought hit last year without the extended intense heat, which had a big impact on crops.

“We were very fortunate, especially in the Corn Belt, that we did not see the combination of extreme heat and drought at the same time. And that actually led to some of those better outcomes than expected for U.S. corn,” explains Rippey.

With USDA currently projecting the 2023 U.S. corn crop to be the largest on record, Rippey says the mild temperatures are what helped save the crops.

“You do see that things actually turned out better in states like Iowa. When you look at the rainfall numbers, they were abysmal, almost as dry as 2012. But then the heat just wasn’t there. And today’s varieties are little bit more tolerant of drought and heat. And the outcome was a little better than we expected,” says Rippey.

It wasn’t all good news. While crop yields turned out better than expected for some farmers, the lack of moisture continued to dwindle grazing conditions and hay stocks in 2023. Those created additional hurdles in rebuilding the shrinking U.S. cattle herd.

So, what was the culprit that caused the intense heat that suffocated the South during the summer months? Rippey says while it’s still being studied, he thinks it’s tied to one major weather event in 2023, in particular.

“I will go out on a limb and say that that may have been an early sneak attack from El Niño ,” says Rippey. “The reason I say that is that because we did have an early onset El Niño. It was pretty much in place by late spring, early summer. It’s pretty consistent with El Niño to have a big ridge of high pressure that comes out of Central America. And at times, we’ve seen it before, that does sometimes extend all the way into the southern tier of the United States.”

He says El Niño can also be tied to the shipping crisis that wreaked havoc on exports in 2023, causing massive shipping delays, as well as forcing shippers to carry lighter loads.

“And certainly what happened in Mexico and parts of Central America, think about the Central American drought that’s causing shipping problems in the Panama Canal. A lot of that, I think, could be tied to the heat in the atmosphere related to the early onset El Niño,” says Rippey.

According to Rippey, the drought in the Midwest can be attributed to the blocking high pressure that wouldn’t budge across Canada this past spring, summer or fall.

“The U.S. Midwest happened to be on the southern end of a lot of that high pressure over Canada. So when we think about that, think about the Canadian wildfires, all the smoke coming down. And we were just on the southern edge of that in the Midwest,” Rippey explains.

He says that, along with Northeasterly winds blocking moisture from the Gulf, is what caused the drought in the Midwest.

“At the same time, high pressure was far enough north that the heat and unusual warmth were actually focused across Canada. So, it wasn’t all that hot on the southern end of the high, but it was dry. And that led to that cool drought in the western Corn Belt,” he adds.

El Niño is still in play, as Rippey says El Niño made a splash once again to close out 2023.

“Now that El Niño has kicked in, it’s a strong event, it could be one of the strongest on record,” says Rippey. “We’re seeing that influence of El Niño starting to grab a hold of the reins of U.S. weather patterns. And that’s pretty normal and certainly should continue into early 2024.”

What’s on tap for 2024? Rippey forecasts the intense El Niño will lead to what he calls “pretty profound” impacts for the rest of the winter, and even into spring.

Heat Warnings Sweep Across U.S.: What You Should Know

Tue, 14 Jun 2022 20:37:49 GMT

This week, dangerous heat is sweeping across Texas to Wisconsin to Ohio to Georgia.

It’s particularly important to watch out for yourself and each other when heat indexes reach 91 degrees or higher, as referenced by the Mayo Clinic. The heat index is a value calculated with the outside temperature and humidity—which is important as in high humidity environments you can’t effectively sweat. This makes people more prone to heat exhaustion or heat stroke.

(Farm Journal)

Health experts say it can take several weeks to adjust to higher temperatures. With this sudden onset of wide-spread heat, it’s important everyone takes steps to stay safe.

Watch Out for Each Other

Iowa State Extension highlights how the signs of heat stress are often overlooked by the victim. As their report details, “The individual may at ﬁrst be confused or unable to concentrate, followed by more severe symptoms, such as fainting and/or collapsing. If heat stress symptoms occur, move the victim to a cool, shaded area, give him or her water, and immediately contact a supervisor or another individual to provide assistance.

8 Tips to Stay Safe Outside in Heat

Stay hydrated, which helps your body swat and keep a normal body temperature.
Eat light—but often.
Protect your skin. Wear hats with brims, sunblock, sunglasses. Reapply sunscreen every two hours (or more often if swimming or sweating.)
Wear loosefitting, lightweight clothing.
When possible, schedule activities in cooler part of day.
Take breaks
Take extra precautions with certain medications that affect your body’s hydration or ability to dissipate heat.
Be cautious if you have certain conditions or a history of previous heat illness.
