Probably one of my tor favorite photos (that I captured) from this last storm season. It was in the earlier stages of the Arnett, OK tornado of May 18. Of course, it's hard to compete with Dickens, NE or Gary, SD, but I wasn't on either of those two events. With @francescodemartin.bsky.social

Sunrise in 16 seconds. I sort of regret not doing the sculpted wave cloud to the west instead. Also, sorry for the small jump in the middle.

My first attempt at research in fires and air quality was just published in JGR-Atmos. It reviews the performance of NOAA's UFS-AQM model during the terrible 2020 wildfire season in the US and preludes a forthcoming paper on a novel UFS-AQM ensemble prediction system. doi.org/10.1029/2025...

I don't know if I've ever seen the snow at high elevation this pitiful by Nov 8 in my 15 years living in CO. Here are views of an almost snow-free Sawtooth between Bierstadt and Blue Sky and a slightly more snowy (a fresh dusting that will be gone in a day or two) Square Top Mountain this morning.

After a devastating landfall in Jamaica, Major Hurricane #Melissa has emerged north of the island. In a few hours it will strike again, this time in southern Cuba.

This has probably already been posted here, but Melissa has displayed a classic mesovortex pattern that can be modeled in the simplest 2D atmospheric models ("nondivergent barotropic models"). Here's a comparison of this morning's VIS sat and Kossin and Schubert (2001) experiments.

#Melissa is intensifying very rapidly this evening. TDR structure is nearly perfect for a TC of this intensity. Incredibly symmetric, strong eyewall, and a deep, aligned circulation. The sky is the limit. Very scary situation.
