TRUMP on Truth Social just now: "I agree to suspend the bombing and attack of Iran for a period of two weeks."

Update in the NCAR case: Hearing about a prelim injunction is scheduled for May 7, but the plaintiff's motion for discovery (i.e. rationale for NSF's actions) is denied for now. www.courtlistener.com/docket/72496...

Initial WH budget request details for FY27 are out. Not a ton of numbers, but some R&D highlights: -"maintains funding for research in artificial intelligence and quantum information science at key agencies" -"$1.2 billion for AI to support seven AI supercomputers at the Argonne and Oak Ridge."

The Artemis astronauts have their own laptops and tablets loaded with entertainment. I really hope we get to see one of them playing Kerbal Space Program or watching Apollo 13 on their way to the moon.

For National AI Literacy Day, NCAR CISL scientists will discuss AI machine learning models & visualizations along w/ emerging opportunities & challenges of AI application in Earth system science. Join us virtually on Friday, March 27, at 11 AM MDT. https://bit.ly/4bPLAMR

UCS filed Freedom of Information Act requests to the NSF to publicly release all of its communications about its plans to restructure the National Center for Atmospheric Research (NCAR). “NCAR represents one of the most successful models of federally supported scientific infrastructure in the US.”

🚨 BREAKING: A federal judge has ruled in favor of @ameracadpeds.bsky.social and issued a preliminary injunction against the CDC. The ruling pauses the Jan 2026 childhood immunization schedule revisions, blocks RFK Jr's 13 recent ACIP member appointments, and pauses all votes taken by the committee.

The full complaint is worth a read. There are several additional overreaches in there that I wasn't previously aware of.

NCAR is the backbone of Earth system science in the US and a global leader in open climate research. It directly supports our mission. Alongside a wide range of peers in the scientific research community, we submitted a letter to NSF strongly opposing any efforts to dismantle or restructure NCAR.

This should be the biggest weather and climate news on your radar today. You can send an email today to say why dismantling NCAR is a bad idea for everyone: [email protected]

🧵In support of NOAA+OAR+NSSL's R2O efforts, for those here involved in severe-storm warning operations, I'll share some results from my current study on radar-based prediction of hail size, which focuses on improved detection of giant hail. Background info (from an article submitted to WAF) (1/11)

The NSF has provided no evidence to justify dismantling the National Center for Atmospheric Research (NCAR). Doing so would undermine one of the nation’s most vital scientific institutions. @ncar-ucar.bsky.social Read the letter UCS submitted today: 🔗 act.ucsusa.org/3NeWZh1

This is more like it!

Speaking only for me and not my employer, I would have expected a much more unequivocal statement supporting keeping NCAR together, especially given how much volunteer work NCAR staff do to make AMS function. Calling for a thorough review makes it sound like NCAR did something wrong.

Looks like the southern storm is producing an above-anvil cirrus plume.

Most detailed reporting I've seen on what might happen with NCAR. FYI, the president of Lynker is a former UCAR exec and was in the W. Bush administration.

Avoiding false alarms leads to hesitation and lost lead time around critical decision thresholds. It is visible in reliability diagrams for convective outlooks and hurricane RI too. The social penalty is higher for false alarms b/c more people are complaining afterward.

The Inspector General for NSF must launch an investigation into the Trump administration’s alleged attempt to sell-off parts of NCAR — immediately! 👇🏽👇🏽👇🏽

Observational evidence for the use of a semi-slip lower boundary condition in idealized tornado models.

Thank you!

Some exciting news to share: very soon, NOAA Research will be hiring new federal employees into science positions across the agency! A couple of notes: 1) They will only be open on USAJobs for seven days. 2) Multiple positions at different sites may be in one posting. (1/2)

According to the governor’s spokesperson, no action has been taken re: Peters. His office adds that Polis is not considering a pardon, but commutation remains on the table.

The National Science Foundation is systematically being converted to the National AI and Quantum Research Foundation. “I see it as the administration exerting political control over what has traditionally been NSF’s ability to fund the best science.”

If I wanted to know what ChatGPT thought I'd fucking well ask ChatGPT! I'm asking YOU because you're a human and you have experience!

S.3926, the Weather Research and Forecasting Innovation Reauthorization Act of 2026, will be marked up in committee next week. It’s a bipartisan act that should be able to pass the Senate without much issue. A comprehensive summary is available below. (1/2) www.commerce.senate.gov/2026/2/cantw...

A view we will not soon forget. The Blizzard of 2026.

You often hear "software development is changing, and we must adapt" because of Claude Code. But for my entire career, code has been the *easiest* part of making shit people care about, and we still haven't adapted. The easier coding becomes, the less often we ask "do users actually NEED this?"

All the Denver airport trains broke down so everyone had to walk across the bridge and somehow go from there. Looks like trains are starting to run again but there’s a big line down the escalators.

Lots of satellite mosaics in Houston at #AMS2026 but only one made of real tiles.

I'm providing an update on CREDIT at 4:30 PM today in 330A at #AMS2026. Here's a taste of some of the changing views on ML weather prediction I will be providing. (Thanks @plustssn.autumnsky.us for the last minute bug fix!)

Bridging Physics & AI in Climate Modeling 🌍🤖 Introducing JCM v1.0: A fully differentiable, intermediate-complexity atmospheric model built in Python/JAX. Training hybrid models is hard because legacy code lacks gradients. JCM solves this.

My UCSB colleague Gurusha Juneja wrote a python tool to auto-check your bibtex for hallucinated citations: pypi.org/project/harcx/ It supports papers, books, and URLs. Usage: pip install harcx harcx references.bib

When flying in winter, it is reassuring to have a pilot with an upper Midwest accent. See y’all in Houston!

Alex Pretti was a colleague at the VA. We hired him to recruit for our trial. He became an ICU nurse- I lover working with him. He was a good kind person who lived to help and these fuckers executed him. White. Hot. Rage.

NSF just posted their Dear Colleague Letter regarding the restructuring of NCAR. www.nsf.gov/funding/info...

Houston/Galveston NWS has a fantastic, detailed discussion of the uncertainties and potential impacts with the upcoming winter storm in the area. See forecast.weather.gov/product.php?...

The GFS continues to be the outlier with how far south it pushes below-freezing air into Houston Sunday morn (all the way to the coast). The Euro and now the HRRR and other experimental CAMs are generally keeping temperatures above freezing Sunday morning and only freeze Sunday night (after precip).

Papers due Feb 6! Machine Learning for Remote Sensing at ICLR 2026 (in person in Rio de Janeiro). This workshop promotes trans-disciplinary research through diverse view-points to tackle pressing questions, such as climate change, social inequalities, biodiversity, and food security.

Breaking: Senate ends debate on minibus bill that will fund most fed science agencies, and votes 82-15 for final passage. Goes to POTUS now for signature to become law. open.substack.com/pub/balanced...

This is just down the street from historic Fort Snelling, where Dred Scott lived in slavery for years even though he resided in a free state.

Why do I still gravitate away from config files toward modifying things in code or jupyter notebooks? Code forces more surrounding context for the choices while configs remove it by default. Need to find an interface that has the best of both, like the Mario Kart character/vehicle select screens.

The Minibus Appropriations bill providing funding to NSF, NASA, NOAA, DOE, and EPA among others and support for government scientific research just overwhelmingly passed the House with 397 yes votes! On to the Senate.

I make an appearance in a new Washington Post video on AI for severe weather prediction. Check it out at www.washingtonpost.com/video/techno...

I recently learned this trick for getting images out of a Google Doc, so I wanted to share in case it's useful. File -> Download -> Web Page. Then unzip, and you've got a nice folder of images!
