I’m very excited to announce the latest release of SHARPlib, v1.4.0. This might be one of the coolest updates yet (in my opinion) and results in dramatic performance improvements through the use of pseudoadiabatic lookup tables. Available on PyPI/conda-forge. github.com/keltonhalber...

Do you like music? Do you like Wisconsin weather? Do you like those things mashed together? Come see a concert in April that takes Wisconsin weather data from Wisconet and turns it into music! music.wisc.edu/event/earth-...

I miss the band Dopapod.. they were solid. They come up every so often in my playlists and it makes me smile. Saw ‘em a few times at intimate venues in Madison

The current heatwave in the US Southwest is utterly destroying many records for this time of year. Phoenix, Arizona has ~90 years of daily temperature data, and yet recent temperatures beat the previous March record by 5 °F (2.8 °C), and would actually tie the record for April.

JUST IN: A consortium of universities filed a lawsuit Monday to stop the Trump administration’s planned dismantling of Boulder’s NCAR, alleging that the planned reorganization violates the Constitution and federal law.

This move is so incredibly dumb, and ultimately so destructive to our understanding of extreme weather and of climate change, that it could only have come from the Trump administration. Truly dangerous idiocy. www.nytimes.com/2026/03/13/c...

If you think you're going to see tonight's lunar eclipse, you're not. Cloudy skies abound tonight, so just sleep through it. Solar eclipses are better anyways.

Presale ticket order came through for both Madison Phish shows this summer. Can't wait!

#HigherEd #AcademicSky *Please* amplify this risk. The US DOE wants to implement an earnings test on all undergrads and grads--if grads of your programs do not earn a specified amount upon receiving their degrees, your programs risk losing federal funding. The earnings tests begin *this October*.

Join us on Tues, March 24, for our 15th annual Leonard Robock Lecture! Dr. Clara Deser, senior scientist at NCAR, will discuss "A Range of Outcomes: The Combined Effects of Natural and Anthropogenic Influences on Local Climate.” Register today: go.wisc.edu/pc3ui6

Today at 3:30 pm CT: Clear-air turbulence (CAT) research—and plenty of CAT puns—with John Knox, the recipient of the 2025 AOS Distinguished Alumni Award! Livestream: www.youtube.com/watch?v=Y7AV...

Just bought tix to see the band Eggy @eggymusic.bsky.social at High Noon Saloon here in Madison in March. Heard good things about them, really looking forward to to the show!

If you're still at #AMS2026 and looking for something to see this afternoon, I'll be presenting progress we've made at the @nyswrcc.bsky.social at the 1st Annual Disaster and Emergency Management Symposium, at 2:15 in 352A. Guest appearance by NY Governor Hochul (sort of).

Kare 11 local news just read, in full, this statement from Michael and Susan Pretti, the parents of Alex Pretti. "Please get the truth out about our son."

For #AMS2026 - John and @pamknox.bsky.social report that Elevator #14 at the headquarters Hilton should be avoided at all costs. They had to be freed from it by Houston Fire Dept after it got stuck, and the FD told them it happens regularly with that elevator.

National media should really be covering the fact thay every major school, museum, and arts institution in the Twin Cities, and hundreds of local businesses are closed tomorrow to protest federal occupation. Nothing like this at this scale has happened anywhere in America anytime in living memory.

AI-driven global model output from NCEP is now available in NSF Unidata data streams! Ready to explore? We’ve created an IDV bundle and Jupyter notebook to help you dive in.

For those at #agu25 #saveNCAR 12:15pm - Group Photo/Video at the "science strong" wall across from the Plenary Hall at the entrance to the convention center 1:30-5:30pm - drop in interviews at PJs Coffee in front of Hall C - look for the person with the "We ❤️ NCAR" sign. More info:

#AGU25 folks, there is a rapid- response town hall TODAY on the #NCAR dismantling at 1 pm, La Nouvelle Orleans ballroom C (per an AGU media advisory)

It’s simply not possible to overstate how important NCAR is to US and world science. We need to fight this with everything we’ve got.

Note: NCAR/UCAR websites will be offline most of the day today due to unrelated power issues.

NCAR and UCAR have released a statement. NSF has not provided any guidance to UCAR or NCAR leadership about this whole situation. news.ucar.edu/133054/ucar-...

Devastating and dangerous blow to the weather and climate community tonight, as 20,000 earth and space scientists meet at #AGU25. New @ucs.org statement from @carlonimbus.bsky.social on the Trump administration plans to dismantle @ncar-ucar.bsky.social: www.ucs.org/about/news/t...

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.

I'm not sure most folks are aware of the immense magnitude of loss this would entail for the global weather and climate community, and beyond. NCAR has played a greater cumulative role in advancing weather prediction and atmospheric modeling than perhaps any other single entity in the world.

Key misunderstanding I want to get ahead of: NCAR isn't really a government agency like NIH or NSF. It's one of the largest NSF grants in history, and is given to a non-profit org called UCAR, whose job is to make NCAR exist (www.nsf.gov/awardsearch/...). That means the buck stops with NSF right now

NCAR is quite literally our global mothership. Everyone who works in climate and weather has passed through its doors and benefited from its incredible resources. Dismantling NCAR is like taking a sledgehammer to the keystone holding up our scientific understanding of the planet. Unbelievable.

A deeply dangerous — and blatantly retaliatory action against Colorado — by the Trump administration. NCAR is one of the most renowned scientific facilities in the WORLD — where scientists perform cutting-edge research everyday. We will fight this reckless directive with every legal tool we have.

Do you love to write code or teach others about data-centered Earth Systems Science? Interested in the interplay of science and data? The NSF Unidata Summer Internship program is looking for you! Apply by February 6, 2026 to work with us next summer: buff.ly/5nsLdRu

It's easy to be numb because it's par for the course nowadays, but repeatedly calling a reporter who asks a reasonable question "stupid" is conduct unbecoming for a small-town mayor, let alone the President of the United States. The press exists to play a watchdog role, not be a supplicant.

After many long months, I’m excited to announce: we’re hiring! GSL through CIRES is looking to hire a land-surface model developer. Come join us in developing the next generation of storm-scale NWP for NOAA & community! Closes 12/12, pls contact me w/ questions. jobs.colorado.edu/jobs/JobDeta...

Brief aurora display here on the east side of Madison, WI. Visible to naked eye in color but not as vivid as these photos

Trump just continually shooting our country in the face. This unwarranted (and likely illegal) destruction of Goddard is madness. It jeopardizes the next several decades of space exploration.
