2/2 🌪️ Meanwhile a strong, multi-vortex tornado in Union City, Michigan. Crazy to see the house get ripped awway likke nothing! Video from Meteorologist Will Haenni WWMT #Tornado #UnionCity #Michigan

From a 0% marginal day to a confirmed #supercell #tornado — sometimes the high plains over-deliver🌪️ May 25, 2017 I caught this spinner in Yuma County, CO, on timelapse — Turretcam footage shows clear ground circulation (arrow) forming right on the inflow boundary. Full chase log link in 🧵 #WxSky

Everyone remembers Wray, but for a few the magic started in Eckley. May 7, 2016 I blasted east, betting on a #supercell cluster erupting near the state border. Just as I arrived this scene unfolded — a ghostly #tornado touching down north of Eckley, #Colorado 🌪️ Full chase log link in 🧵 #WxSky

Please clean the ice and snow off your vehicles before driving!

The US NSF has put out a "dear colleagues" letter that is essentially a yard sale list for @ncar-ucar.bsky.social It asks questions such as, who'd like to take over some of NCAR's programs? Is anyone interested in commercial use of the Mesa Lab? If you have thoughts, send them to [email protected]

It's gonna be May 🌪️ in 71 days. Tornadoes will again be roaming the Plains. Flashback: May 17, 2019 I was chasing this monster #supercell near McCook #Nebraska. After a white-knuckle detour through a torrential rain core, I broke out just in time to intercept this EF-1 #tornado near Farnam. #WxSky

This thread shows a deliberate defunding of U.S. science, engineering, social science, innovation, and education excellence. It’s a U.S. national security, competitiveness, and economic disaster.

A personal update from veteran French storm chaser and world-class filmmaker Chris Asselin⤵️

Snow squall rolling into Laramie earlier this morning

This is fine

Great piece out today in Physics Today on historical origins, contemporary relevance, & fundamental irreplaceability of the National Center for Atmospheric Research, which remains at imminent risk of dismantling for partisan political reasons.

AMS is deeply concerned by the repeal of EPA’s 2009 Endangerment Finding, which concluded greenhouse gas emissions harm health and well-being. The science remains clear: human-caused climate change is already causing harmful impacts. Read the full statement: https://bit.ly/4tBwz9w

NSF Update Funding curve overall. A little bit of progress in the past week, but only a little bit. Now by Directorate... 1/11

I, for one, am not surprised that the pseudoscientific LRC is at the Chaser Summit. Here are the results of my review of the LRC from NWA in September. It performs worse than climo for temperatures and no better than chance for precipitation.

Stop Guessing, Start Planning. Ever look at a single snow forecast and think, "But what are the actual odds?" The Probabilistic Precipitation Portal is a resource to help you get ahead of the storm by moving beyond a single number to give you the full picture. www.wpc.ncep.noaa.gov/Prob_Precip/ 👇

The killing of Alex Pretti is a heartbreaking tragedy. It should also be a wake-up call to every American, regardless of party, that many of our core values as a nation are increasingly under assault.

Yikes! This map shows potential ice accretion from HRRR model output processed through FRAM (freezing rain accumulation model), which is far more accurate than much of the raw freezing rain accumulation model output that is widely available elsewhere.

( #NWSWPC): 🚨 MAJOR WINTER STORM Begins TODAY 🚨 Heavy snow and crippling ice will impact a large region, along with over 170 MILLION AMERICANS from the Southern Rockies/Plains today towards the Northeast by Sunday. #USwx #wx Be sure to stay safe and follow winter safety: www.weather.gov/safety/

Do you appreciate @nws.noaa.gov's posts on Bluesky? Did you know that this account is a pilot program that may or may not be continued and even expanded to NWS field offices? NWS is soliciting comments here! www.surveymonkey.com/r/PrototypeN... Press release: www.weather.gov/media/notifi...

Winter weather is forecast to impact a large part of the country in the coming days. Will there be snow, ice, rain? NWS Meteorologist Haley Thiem explains how the temperature of the air between the clouds and the ground determine the type of precipitation you get.

FY2026 NOAA/NASA/NSF budgets approved in Congress—a sharp rebuke to the White House (Project 2025) plans, with funding mostly maintained, safeguarding national labs, plus a 10% boost to NWS to "support full staffing" (anti-DOGE). No NCAR guarantee though balancedweather.substack.com?utm_source=n...

January 6th should have been America’s second chance at life; a moment for us to speak unequivocally that no one is above the law and no individual is greater than the whole... johnpavlovitz.substack.com/p/the-januar...

Never before seen footage‼️ Tornado genesis of the Clear Lake, South Dakota tornado earlier this year. @myradar.bsky.social #tornado #weather

time for the traditional Colorado Christmas day walk through the park in shorts and short sleeves (yet another easily broken record high temp today)

"Without NCAR’s infrastructure + supercomputing abilities, many small colleges & universities wouldn’t be able to do research with the latest models. NCAR research influences every piece of weather & climate prediction in the US: air quality, droughts, hurricanes + more." - @carlonimbus.bsky.social

Alarmed by reports the Trump administration may cut funding for freight safety and dismantle NCAR. As a global leader in earth systems science, NCAR’s work protects lives, strengthens the economy, and helps communities prepare for extreme weather and climate impacts.

WATER IS FALLING FROM THE SKY IN DENVER

The sun is bringing the beauty both night and day this week with overnight Aurora's followed by a spectacular sunrise with morning's first light splashing on the underside of a cloud deck over Colorado.

New video from veteran storm chaser Dan Robinson on fair use makes a lot of great points. TL;DR -- pay fairly for what you use youtu.be/ETTte5gUvTQ?...

And here's a short explainer on aurora colors! 🎨

That red was RED to the naked eye. Some green embedded in the red parts as well.

Phone photo of back yard aurora in Denver's light pollution

Absolutely wild naked eye visible pillars all the way down here on the Oklahoma/Texas border. Cell phone shot here. #aurora

I am on my way home to Toronto and the aurorae are absolutely phenomenal. If you are anywhere in the northern half of the continent, get outside and look up! Or better still, put your camera on a 10 second exposure and point it up.

Ope

You know what? There's actually a tested solution to this! it is brilliantly simple, and it WORKS. I would love to see @bsky.app and @support.bsky.team test this out. www.ucl.ac.uk/news/2023/ju...

I've published my storm chasing rendering style here - enjoy! github.com/pqo/stormcha...

Thanks for the warm welcome back, Bsky. It’s so much more pleasant here without the daily episode of Idiocracy. 🙃 Here’s a Colorado supercell from August resulting from 3 (three!) storm mergers. 🌀 Got a tad surprised by the intensity & thusly was a little closer than usual…

Remember the glowing orb video from earlier this year that was widely and uncritically described as ball lightning? Chris Asselin took the time to investigate...⚡

Tornado near Pleaant View, Colorado this afternoon…near the Utah/Colorado line in southwestern Colorado! 📸: Landan Wilson

Two more angles of this afternoon’s #tornado in southeast Utah. From X and Facebook. #WxSky

Why do we care about continued investment in our weather radar infrastructure? Without a reliable, modernized radar network, we lose valuable time in seeing tornadoes *before* they threaten places and people. The below percentages indicate that radar prompts 9 out of 10 warnings!

One year ago today I was making what may be the easiest forecast of my life in central South Dakota. This long-lived tornado was just the icing we all knew was coming to top off the cake. 8.28.2024 - Mound City, SD

Entry-level meteorologist positions (I think 40 of them) are posted! I promise the NWS is still an amazing place to work and full of wonderful, passionate people. And we are going to need more great people, with all kinds of skill sets.

There is a new world record for the longest lightning flash - 515 miles! The World Meteorological Organization has certified a lightning flash that extended from near Dallas, TX, to near Kansas City, MO, on October 22, 2017, as the new longest lightning flash. ⚡🧪🧵 (1/3) wmo.int/media/news/w...

Absolutely incredible view of the earlier Westcliffe tornado! This vantage point is simply amazing. Wow times a million! 📸: Rick Sandoval #COwx

Actually, it’s only a Derecho if it comes from the Derecho region of Central Iowa. Otherwise it’s just a sparkling squall line.
