Very interesting modality here. Driven by a La-Nina year?

Perfect example of slight clues that give away AI

This is such a bad idea.

Mental health in the Atmospheric Sciences at @ametsoc.org . Great session so far. One of my favorite tidbits so far, and I am paraphrasing: "In case you have not noticed, it does not matter where you are, its TOUGH in the water weather enterprise right now..." Truth.

I give you a Monday night cleanse...

If you parent a college student, could you pretty please with sugar on top ask them to stop using ChatGPT to email their professors? These emails are driving us slowly bananas.

Happening in about an hour. Can't be there, but @zombietrev5k.bsky.social is running the show, and has offered to give some terrible takes in my honor #AMS2026 #DrinkingWithScientists

@nws.noaa.gov Director Ken Graham presented on NOAA’s modeling grand challenge at #AMS2026 this morning. He announced that the NWS is moving to MPAS as its modeling dynamical core, with his #1 moonshot goal being a global, fully coupled 3-km Earth prediction system using MPAS.

We've got a sizable Purdue EAPS cohort here at #AMS2026. Threaded below are this week's presentations by me and students who've worked in my lab (WRRL): 🧵⬇️

It’s cold. Like, really cold. Still biked. #MSPCycleCast

University partners around the country are launching weather balloons today as part of CUSP-ARR in support of AR-RECON and other field campaigns. Data are being ingested into the operational models for improved predictions!

You should be preparing now for a significant winter storm to impact you with a good chance of 6-12 inches of snow or significant ice, at times near white-out conditions, impassable roads, and life-threatening cold. ticker.mesonet.org #okwx #okmesonet

Continuing to monitor potential for ice in the Houston area. For the Houston area, this will likely be an inconvenient but most likely manageable event. If you have travel plans Sat night or Sunday (looking at #AMS2026 folks), there will likely be challenges.

Code coming soon but it worked!

Yesterday it was cows using tools, today its penguins using satellite imagery.

Hey Bluesky Hivemind! Anyone written code to automatically fetch freezing rain or icing reports? ChatGPT got me some way but winter reports are not with the "other" SPC reports. Any idea where this tool pulls data from: www.spc.noaa.gov/exper/report...

Good news: I am less likely to catch or spread the @ametsoc.org Annual meeting bug. Bad news: I got my getting sick in early... Blerg!

Friday morning temperature anomalies from the GFS. While far from a record this airmass will be proper cold for #Chicago

Fascinating radar loop. Two distinct atmospheric stability states. North is snowing through a stable layer and south is clearly convective.

Great work @climasillinois.bsky.social @prairieresearch.bsky.social 's @trentford.bsky.social! Nice #scicoms on @wbez.org www.wbez.org/curious-city...

Even after the news last week, we are still doing great research here at NCAR. My group has released a new paper, led by John Schreck, on arxiv about an efficient method for generating calibrated AI weather ensembles with reproducible scale specific perturbations. arxiv.org/abs/2512.18815

Wow... I hope but doubt the #AGU25 wifi speeds will be this fast all week.

A strong clipper is expected to bring the threat of heavy snow and high winds across the upper Midwest on Tuesday then across the Great Lakes on Wednesday. Snow totals of 4-8 inches can still be expected across areas of North Dakota through the central Great Lakes. Check the latest at weather.gov.

I believe eigen fly. I believe eigen touch the sky.

Amazing week of results from AI4Science with NeurIPS and MRS. But, for those who couldn't make it, post a link to your research here we can boost you too!

Good morning from the high country!

No turkeys in our household. Lamb is what is for our Thanksgiving meal. Marinade is a Jamie Oliver recipe using fennel, cumin, cloves, garlic, rosemary, peel and juice of an orange, ketchup, balsamic vinegar and olive oil!

Before you pour on the gravy this Thanksgiving, take a closer look at its container. on.nbcboston.com/WIzscxb

I’d recommend the resources from @projectpythia.bsky.social projectpythia.org Specifically look at Foundations and the MetPy cookbook: projectpythia.org/metpy-cookbo...
