Thanks to the local AMS chapter and the NY office for the invite to give a talk this morning. The Open House had a great turnout and it was nice chatting with the forecasters (and visitors).

The supercell that produced the Barnsdall, OK EF4 tornado had a ZDR column area of 60 square km (based on our algorithm) ~1.5 km above the freezing level just prior to tornado formation, consistent w/ other EF4 tornadoes. At 300 m above the freezing level, it was 111 square km.

A potentially awful situation is unfolding in central Long Island right now. The NYS Mesonet at UAlbany's Stony Brook site has already observed ~8" of rain in the past 24 hours, with nearly all of that falling since 6PM. They've observed an incredible 3.5" in one hour. More is on the way.

Many thanks to Jake P. Mulholland, Ph.D. for his visit and great School of Marine and Atmospheric Sciences at SBU talk today on vertical wind shear influences on supercell updraft characteristics. Exciting to have Jake in the SUNY family! (Sorry, I’m bad with photos and only got the last slide 😳)

Thanks to the VTSU Lyndon students, it was a great experience!
