I'll be presenting at #AMS2025 next Monday! My talk at 2:15 pm will highlight our work towards representing uncertainty in future extreme precipitation using WRF ensembles. This work will help military decision makers prepare for extreme precipitation in the coming years.

Intermittent flurries from shallow cumulus here in Champaign today.

Back in the office after #AMS2025! As someone who worked on supercell simulations, the shift to working on extreme rainfall prediction has forced me to take a step back to see things on a different scale. The talks on probable maximum precipitation have me excited for this work!

A Champaign classic. Brutal bike ride home. At least the road surfaces were ice free.

Some nice undulatus clouds on this beautiful spring morning. 🌊 ☁️

Here is the estimated time of arrival for Friday night's storms, along with potential hazards. #ILwx

Looks like the warn on forecast system will be running a Midwest domain today starting at 17z. Could be useful to monitor this evening as storms approach. WoFS: wof.nssl.noaa.gov

Fire near Decatur?

Targeted Lawton, OK, for the last day of our trip. We’ll see if one of these can take off out ahead of the cold front farther west.

For years, I've wanted a way to get a text when friends or family across the country were under critical NWS warnings—so I built it. Meet nausicawx.com. Tornadoes, severe storms, flash floods, freeze warnings, and more. Get instant SMS alerts for multiple locations.

Play suspended at the Philadelphia Eagles stadium, rightfully so, for lightning in the area. But they broadcasted a severe thunderstorm warning message on the stadium PA, which appears to be inaccurate?
