To quote the @nws.noaa.gov Phoenix forecast discussion: "If this watch were to be upgraded to a Extreme Heat Warning, it would become the earliest heat warning to go into effect, with the current earliest instance occurring between April 26th and 30th of 2020." Spoiler: This watch is now a warning.

Remarkable. 114 is the official NOAA forecast for Mecca, CA on Friday. That would not only beat the March US record (107 in Mecca) but also the April US record of 113 in Death Valley. #heatwave

It's March Madness, U.S. weather-style! @bhensonweather.bsky.social and I have the latest on the current Great Lakes blizzard, record Nebraska wildfires, Mid-Atlantic tornado threat, Hawaii record rains, and the mind-boggling Southwest U.S. heat wave: yaleclimateconnections.org/2026/03/pick...

“Audibly gasped” is not a phrase I hear much in NWS discussions. From NWS-Monterey: “The guidance on the strength of this heat wave is remarkable. I audibly gasped when I saw the ECMWF Extreme Forecast Index for maximum temperatures next week. I have never seen it anywhere near this aggressive.”

Am I the only person tired of shattering all-time records?

Would you believe there's *another* massive fire in W NE? The #CottonwoodFire (100K acres) is across I-80 from the #MorrillFire (500K+ acres) FIre crews from Omaha are heading across the state to help out. Omaha's fire chief: "This is rather unprecedented." northplattepost.com/posts/8813c3...

The Morrill Fire in Nebraska has killed 1 and consumed 549,000 acres with 0% containment. This is more than 10% of the entire area burned by U.S. wildfires in 2025, and makes it one of the 20 largest fires in U.S. history. Sunday forecast is grim: High Wind Warning, 25-35 mph winds, gusting to 50.

Even for Michigan's U.P., getting 2-3+ feet of snow over such a wide area is super-rare.

🥵 History will be made next week! The NOAA NDFD forecast high for Palm Springs, CA on Friday is now 111!! Insane for March. That would smash the current US record for hottest March day (108°) in Texas. 1/

a lot has already been written about the heat wave next week, including @weatherwest.bsky.social’s posts here. But it is hard to describe how truly outlandish the forecast is for next week. This is looking to be so far outside of anything that’s been observed before in March in the western US.

Record heat will bake Los Angeles and the Southwest melting precious snow and setting the stage for a fire summer. CA measures its snow on April 1 to set supplies for the coming year. We will see what is left. #climate #water #california www.bloomberg.com/news/article...

I feel the word “historic” almost fails to meet the moment in describing next week’s heat dome in the West - that’s how unprecedented it is for March! The record part of this heat dome is literally everywhere colored in magenta… so yeah, that’s a Huge area… 1/

“The snowpack is extremely low across much of the West, not because precipitation was extremely low … but specifically because temperatures were record warm. That is the classic signature of a warming climate on mountain snowpack,” @weatherwest.bsky.social told @edwardsanthonyb.bsky.social

two days ago it hit 80° F (27° C) i thought False Spring yesterday also 80° F (27° C) so maybe Early Spring today 90° F (32° C) now i'm wondering when did New Jersey move to Florida? #FreeVerse #Poetry #JustWrite #Weather #Spring #FalseSpring #NewJersey #Florida #Climate

Absurd heat! Despite our best efforts, the monster heat dome is bound to be "undersold" by the meteorology community. Why? Because intensity like this is almost never seen. This thing has the potential to be Epic for Mid-March, and not in a good way… 1/

Superb—and *very* unsettling—roundup from @weatherwest.bsky.social. The imminent SW heat wave (likely the most intense for March on record) will involve similar dynamics to the June 2021 scorcher in the PacNW. This landscape-parching heat may set the stage for serious fire/drought trouble by summer.

El Niño Watch issued today by NOAA. Looks like record global temps in 2027 (and maybe even 2026) are virtually a lock, based on the strong likelihood of a potent 2026-27 event.

Weather West update on a prolonged and very likely record-breaking March heatwave in the western U.S. that will begin Thursday in some areas & actually not reach its peak for another 7-10 days in some spots. This forecast is truly extraordinary for March.

How's about this for a wacko record? PHX all-time record March high is 100F, set one time. The current NBM forecast has PHX hitting 101F or higher (at least) 5 days in a row, topping out at 106F.

The extreme events of February 2026 highlight the growing impacts of #climate change and the pressing need for global action. 🌡️ Global temperatures were 1.49°C above pre-industrial levels, for the 5th warmest February More details: climate.copernicus.eu/press-releases

Folks still thawing out might be wondering: How bad a U.S. winter was it overall? Very bad – that is, if you’re concerned about long-term warming and intensified drought impacts. (2nd warmest and 5th driest on record.) @climateconnections.bsky.social yaleclimateconnections.org/2026/03/we-j...

Pretty amazing in SoCal. Downtown LA may hit 100° on Friday! That’s crazy. Checked the data. The earliest 100 was April 4th. So IF this happens, it would be 3 full weeks ahead of the earliest 100. Also obviously the hottest March temp on record in LA as well (97 is the monthly record).

Some people ask me, why track record temperatures? More heat does not affect me, so why should I care? Because record warmth is a big symptom of the climate's health over the last few decades, giving us warning of what may come. Heed the drip drip drip coming into the Titanic. @katharinehayhoe.com

Lots of buzz online about an upcoming major March heatwave for the American SW & California. And in this case, it does indeed appear increasingly likely than an extremely anomalous and even record-breaking heatwave may envelop much of the SW about a week from now.

Current indications are that late spring or even mid-summer-like (in some places) heat will arrive and persist for a fairly extended duration across a wide swath of the American West, centered on the Four Corners to Southern CA region. This will induce rapid melt of remaining snowpack.

EXCEPTIONAL HEATWAVE BREWING FOR NEXT WEEK IN COLORADO A powerful ridge is about to park itself over the West next week -- stronger and closer to Colorado than anything we’ve seen in a long time. #COWX #Colorado #Snowpack #Heatwave #COsnow

Slicing and dicing through new @climate.noaa.gov stats for FEB 2026, it has been very warm average temp wise across the lower 48 states. In fact, there were record averages for the last 4 to 12 month periods. @michaelemann.bsky.social @bhensonweather.bsky.social www.ncei.noaa.gov/access/monit...
