Colorado State University is predicting another active Atlantic hurricane season. But that prediction comes with an important caveat, says @drjeffmasters.bsky.social: yaleclimateconnections.org/2025/04/fore...

The NWS office in Paducah, which has to handle some of the most frequent and impactful weather in America and was nearly taken out by a tornado tonight ahead of a catastrophic flood event has to use a parking lot porta potty because they can’t fix plumbing due to the govt funding freeze.

"MOST PROBABLE PEAK TORNADO INTENSITY... 155-190 MPH" 👀https://www.spc.noaa.gov/products/md/md0359.html

A new "particularly dangerous situation" tornado watch is in effect for counties highlighted in magenta through Wednesday evening. Counties highlighted in red are also under a tornado watch. Multiple intense, long-track tornadoes are possible in and around the watch area.

Heads up, Mississippi Valley: Tornadoes and major flooding are brewing for you over the next few days. "Generational flooding with devastating impacts is possible,” per the National Weather Service office in Memphis. yaleclimateconnections.org/2025/04/pote...

68,845,865. That's how many individuals in the United States speak a language other than English at home. Everyone deserves a chance to stay safe during disasters, and I will never stop advocating for that. Thinking of all the communities that are going to be affected by this change.

Apparently the government has decided that weather information only matters for people that can read English and has not renewed a contract it had in place to help broaden the audience. While this is a newer tool, it is one that many people passionately worked on to broaden weather intel for all.

Here’s your chance! :-P

WPC with a foot of rain in the forecast for the Ohio/Mississippi river valleys over the next 7 days, which is a lot. That 2"+ of liquid for the southern Colorado mountains would sure be welcome though.

Who doesn't love a severe thunderstorm watch in southwestern Ontario in March?

Some of the RGV rain totals are bonkers. 36 hour totals of over 14" in Harlingen and nearly 13" just west of Hidalgo, over 12" near Nuevo Progreso on the US/Mexico border. There are currently 3 flash flood emergencies in the area.

Rising global temperatures can influence the timing of events, such as when crops are ready to plant and harvest and when flowers and trees bloom. One example is the timing of the peak cherry tree blossom in Kyoto, Japan, where records stretch back to the ninth century — that’s over 1200 years.

The SPC has upped #tornado chances for the I-5 corridor from Eugene to Tacoma to 5% within 45 km of any given point in that area. This is the highest tornado risk ever forecasted by the SPC for Western Oregon or Western Washington (data back to 2002). #weather #ORwx #WAwx #pdxtst

The first-known #pyroCb in South Korea happened this morning (UTC) on a large fire near Uiseong. PyroCb are wildfire driven thunderstorms that can act like chimneys and transport smoke into the upper troposphere/lower stratosphere. H/T to the pyroCb community/email thread for catching this!

My main takeaway from the new IEA report: Clean energy is accelerating like crazy, but it's still not enough to actually reduce climate pollution. Emissions are still rising as energy demand rises, including for coal, oil, and gas. It's not enough to add clean. We also have to subtract dirty.

I really wish we weren't doing real-life data denial experiments.

So I've been doing this for 35 years, and I'm still always excited when I see something in the atmosphere that wows me. Seeing what looks on visible satellite to be pretty thick dust in IA on the northeast side of an intense low producing blizzard conditions nearby qualifies.

100 years since the Tri-State Tornado, probably NOT the longest tracked, but definitely the deadliest. www.accuweather.com/en/severe-we...

A deadly multi-day onslaught of fire, smoke, dust, severe winds, and tornadic storms swept from the S Plains on Fri to the NE on Sun. No major severe wx expected this week...but more "critical" and "extremely critical" fire-weather conditions are on tap. yaleclimateconnections.org/2025/03/far-...

We'll see if subsequent analysis brings the estimated winds from a violent tornado near Diaz, AR, even higher. Speaking of which, one group of researchers recently looked at why the U.S. hasn't had an EF5-rated tornado in almost 12 years. More: yaleclimateconnections.org/2025/03/new-...

Very likely tornado on the ground near Talladega, AL evidenced by the lowered CC area! Completely rain wrapped so it will be next to impossible to see. For reference, the Talladega Superspeedway sits to the north-northeast of the town itself, closer to I-20.

When 50+ mph winds push massive amounts of dust from the Southern Plains into the Great Lakes…

Some screen shots of the likely tornado damage from WxChasing/Brandon Clement in Tylertown, Mississippi:

The dark blue in the lower image is a signature of airborne tornadic debris :-(

Good account to follow if you want to keep up on the most extreme of NWS warnings.

...#TORNADO EMERGENCY FOR Southeastern Lawrence, Northwest Marion and Southwest Jefferson Davis Counties... #wx #Mississippi #Bassfield

From the @nws.noaa.gov: ⚠️❗️A Particularly Dangerous Situation Tornado Watch is now in effect for much of MS and northern LA until 6 pm CDT Numerous strong long-track tornadoes are likely, along with very large hail and damaging winds Stay weather aware for critical info see spc.noaa.gov

More proof that my colleagues at NWS SPC are the best in the business. Their service is no less than vital.

Folks need to be on extraordinarily high alert across far SE LA and most of MS from midday thru Sat PM. This is as bad as it gets.l tornado-watch-wise.

Strongly worded discussion for tomorrow from SPC tonight, as you'd expect with a categorical High Risk

Another potentially significant tornado developing in the south St. Louis suburbs, this time likely to head toward Arnold/Imperial. #mowx

😳

Spectacular work from NOAA/NWS/SPC. As far back as last Mon 3/10, the highest-possible Day 6 rating was in place over the same gen area as the current Day 2 high risk. Only two other times in its 39-year history has the Day 2 outlook had a "high risk" area. The others were on 4/7/06 and 4/14/12.

The nation's deadliest tornado on record struck a century ago on Tues. 3/18. From today into the weekend, widespread tornadoes will prowl the Mississippi Valley and South in a potentially high-end outbreak, with "extremely critical" fire weather in OK/TX. yaleclimateconnections.org/2025/03/pote...

On top of this severe-storm threat—with strong tornadoes possible on both Fri and Sat—there's an "extremely critical" wildfire threat on Fri (highest possible level) extending unusually far east in TX/OK into the Oklahoma City and Tulsa areas, even approaching DFW. www.spc.noaa.gov/products/fir...

This is the first month in nearly two years – since May 2023 – that did not rank as either first or second warmest on record for that month globally. yaleclimateconnections.org/2025/03/febr...

Summer temperature outlook from the ECMWF. 🔥

Despite a Gulf Coast snowstorm for the ages, and some widespread/prolonged chilly weather in January, this winter was still milder overall than the vast bulk of contiguous U.S. winters up through the 1980s. Unnervingly dry, too. yaleclimateconnections.org/2025/03/the-...

#SAVENOAA ALERT: We understand that 16 of our colleagues have now had their terminations rescinded. We are thrilled for them, and we welcome this news! However, the vast majority of terminated NOAA employees have not been reinstated, and more cuts are imminent: www.nytimes.com/2025/03/08/c...

We love a good science mystery, especially one with an answer. Q. Why haven't we seen any of nature's most violent tornadoes in the U.S. for 12 years? A. yaleclimateconnections.org/2025/03/new-... New from @bhensonweather.bsky.social

Although the monthly sea surface temperature anomaly in the Niño 3.4 region rose slightly to -0.59°C in February, the latest three-month average (called the Oceanic Niño Index, or ONI) dropped to -0.64°C, the lowest since January 2023! La Niña remains! 🌊 bmcnoldy.earth.miami.edu/tropics/oni/

After losing 2 flight directors (my old job), the NOAA Hurricane Hunters are down to minimum staffing for continuous hurricane flights. And if I still had my old job, I'd be looking for new employment before the next onslaught of cuts. yaleclimateconnections.org/2025/03/noaa...

This 👇 is critical for understanding how a seemingly small cut to NOAA's Hurricane Hunters could have enormous implications for public safety during the upcoming hurricane season. New from @drjeffmasters.bsky.social

Not an exaggeration to say this was pound-for-pound the most effective piece of US public diplomacy in China. Twitter was blocked, but U.S. embassy pollution tweets forced Beijing to start publishing its own pollution data, which fed public outrage. Result: millions breathing vastly less toxic air

Check out the replies to see the land + ocean value, if you dare.

“Graybeal and other US executives are dropping the mention of “climate change” in meetings, even as they continue developing or deploying climate-friendly solutions.”
