Thank you for the pleasant scene, little snow squall #cowx
Just your typical elevated hailstorm moving into Chicago where it’s 39F at the surface but with >1000 J/kg MUCAPE

It's been so warm for cities like Denver, Colorado that even phenological spring has arrived there according to the first leaf out! Wow!

A couple of the wildest graphs I recall making. It's been #warm... at Fort Collins the warmest climatological winter by nearly 4°F! #cowx 🌡️
Fort Collins number of days with TMAX >= 60°F, December through February. "Fort Collins has recorded 38 60°F days this winter. Previous high was 22 (1980-81). The remaining days in the month are all forecast to be 60 or above (five more).
@rschumacher.cloud on a state call this morning, talking about the crazy warmth we've been experiencing. The number of days Fort Collins has passed 60°F this winter, far surpasses any other winter!
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.

The mountain snowpack so far this winter is in bad shape. Long-time Coloradans might remember two other terrible winters for snow: 1976-77 and 1980-81. Our latest blog post takes a look at how this year compares to those snow droughts of the past. #cowx
I had a fun opportunity to chat with some very bright 3rd graders through this collaboration with CPR! The kids managed to stump me on one question :)

Taking off my weather hat for a moment for something more important than the forecast…today is International Holocaust Remembrance Day.
I’ve shared before that my grandparents (mom’s side) are both Holocaust survivors. Please do me a favor and read their story in this thread.
Exceptional. Record-smashing. Disturbingly warm. December 2025 was one for the record books in Colorado.

Since SPC isn’t on BlueSky yet, I’ll share these fun “Wrapped”-style graphics here. Here’s a look back at SPC product issuances in 2025. Stay tuned for a more thorough review of the severe storm season coming in the new year.

This was very fun to work on, emerging from student class projects a few years ago. How sharp can a cold front get? We were able to point to some answers.
Very strong winds and extremely dry conditions are expected across the Front Range tomorrow (Dec. 19). Critical fire weather conditions will be in place, with the greatest risk over parts of Boulder and Jefferson counties.
Key messages below from NWS Boulder. Stay safe and weather aware! #cowx
Map of maximum wind gusts from the ASOS, CoAgMET, and Northern Water networks on 17-18 December 2025.
Extreme winds were observed across eastern Colorado yesterday, with numerous wildfires growing quickly in Yuma County last night. The strongest winds were in the foothills, with several reports of gusts over 100mph. But the >80mph gusts on the eastern plains are perhaps even more unusual. #cowx
Before the 1990s, plane crashes caused by microbursts used to kill planeloads of people fairly regularly.
Dr. Ted Fujita and NCAR scientists figured out how to detect microbursts and warn pilots about them.
Since then? Zero airliner crashes from microbursts.
Exclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.

Any teachers out there? Ramping this back up again and figured I would advertise.
I am on the National Weather Service National School Outreach Team. We are composed of various NWS meteorologists across the country that give school talks about the weather. We can use just about any online platform.

If all this warm and dry November weather has you thinking back to October when there was quite a bit more happening, our monthly summary is for you. Including the big southwest rainstorm and flood, a lack of mountain snow, and more warmth on the Plains:
