I love how the high-frequency satellite imagery from GOES-19 (every minute) shows how the low-level circulation *within* the eye of #Melissa approaches that of a solid body. Notice how the pattern of clouds in the eye doesn't warp but rotates as if it were artwork on a spinning record. (1/3)

Good day collecting rain and hail size distribution data on a tornadic supercell with large hail for @nsficechip.bsky.social in NE CO today! Had 6 probes between 2 teams (led by @tedmwx.bsky.social and myself). Also got this shot of a tornado near Akron, CO, breaking my nearly 6-yr tornado drought!

Awesome corona + iridescence around the gibbous moon tonight! Took a few tries with the iPhone to get the exposure good enough to approximate what it looked like to my eyes. Still doesn’t *quite* do it justice. #AtmosphericOptics
