Actually insane to find out the NSF GRFP is no longer accepting applications from 2nd year graduate students, with no warning... I applied as a senior in undergrad and decided to wait a year to build up skills and my CV before applying again. Guess not...

This is unfair to all who delayed applying as 1st-yr grad students in '24, or who withdrew due to missing letters (expecting eligibility this year), or who are 1st yr students now without sufficient time for a compelling application. Let me know if this is you. #NSFGRFP

@draaronhill.bsky.social how are we feeling fellow Sonic’s franchise fan???

Huge thank you to @wxdave1.bsky.social @streamwise.bsky.social and Hsiu-Wei Hsu for helping with the RaXPol data collection. Also thanks to @deldotdel.bsky.social @ameyanaik123.bsky.social @jwthiesing.bsky.social and Howie Bluestein for operating the bistatic receivers and assisting this deployment

In the still of the tornado at approximately the same time as this scan (thanks @deldotdel.bsky.social), you can see the debris cloud seen in correlation coefficient. Moving forward we'll investigate more photogrammetry of this tornado, as well as genesis of the second tornado near Arnett

This Sunday, we collected a close range dataset of multiple tornadoes near Arnett, OK in RaXPol. Despite scrambling to find a position, we captured the debris cloud, a debris ejection associated with intense RFD, and surface-layer vorticity worms in the inflow and RFD.

The eye of the Arnett, OK tornado, captured by one of our UAVs as it collected scientific data on the environment within.

On April 25th, 2025, the TTU-Ka LIFT teams successfully intercepted a tornado near Muleshoe, TX. First up are PPI scans of the main tornado and the "dancing" vortices/subsequent smaller tornadoes captured by Ka2. 1/2. #LIFT #tornado

Be wary a quiet early May. Despite a seemingly slow start ensemble guidance, climo and sub seasonal Analogs paint a much more interesting picture mid to late Month. Especially for the High Plains.

The Rapid X-band Polarimetric Radar (RaXPol) from OU'S Advanced Radar Research Center (ARRC) beautifully captured the tornado near Matador, Texas last night 🌪️

At it's fastest rotation rate, RaXPol can complete a 360° spin in just 2 seconds and a full volume scan in as little as 20 seconds! #txwx

I think we are getting some slight azimuth errors from the pedestal, makes post processing really fun!

Thanks Pat! Really proud of this dataset. Looks like we had some slight errors from the pedestal during the rapid scan mode

I’m so proud of you!!

We’re excited to share that Dr. Joseph Trujillo-Falcón will join our regular faculty as an Assistant Professor in Fall 2025! He’ll continue his work on effective risk communication in weather and climate.

Gotta go on the very top

I am so terrified

Make no mistake - this is absolutely end all climate-based research (not just climate change) in the US and officially surrender our scientific advantages in climate to countries like China for generations.

LETS GOOOOO

Sometimes I wonder how much more there really is left to learn about supercell environments and tornadoes. And sometimes you look at the radar in a sigtor environment and see this

This is exactly how I visualize them in my head, great way to teach people!

I’m flattered people care about the NWC/SPC, but we’ve got to stop with the false reporting of the ROC lease as the NWC lease. The square footage and annual lease cost are nowhere near in the same ballpark. You guys give me a heart attack every time this happens.

The forbidden green beer

The outpouring of posts, messages, and texts the last few hours is bittersweet. It’s evidence of the incredible community that is made up of everyone at NOAA and associated non-federal organizations, and the shockwaves that result when so many are abruptly cut off.

I’m very proud to be a part of this community.

America 2025 is a scary place...

I was gonna make a stats joke but my moral is already so low from these 8 days I just can’t
