Snow bands are feeding into an arctic front as it moves ESE through PA. Many snow squall warnings accompany the front with localized intense snow and whiteout conditions. Impressive winter radar display.

We need data, Unidata.
Unidata maintains a lot of key weather data infrastructure, including the netCDF data standard and libraries, metpy. data dissemination servers for accessing models and observations from NOAA, and educational resources for the university community. Now everyone is furloughed b/c of Trump and DOGE.

More than 1,000 of my former NOAA colleagues left the agency in one day yesterday. I've been seeing a continuous stream of retirement announcements unlike anything I've ever experienced. It's brought a lot of emotions - I talked about them here.

Again I reiterate, the Warn-on-Forecast project is the culmination of stellar work done by all of us on the team. Weβve heard the success stories, we know the community support, and we have so much to learn to make it even better.
This is ONE example of bleeding-edge research that deserves to stay.

This literally life-saving advance weather warning program is under attack because it's part of NOAA. When you're calling and writing to your reps, please consider putting a word in for it too.
