Not sure if anyone else bothered to chase today, but I did and it came out better than yesterday. Got on an isolated cell that crossed into Monroe and St. Clair Counties, IL from Jefferson Co., MO. It never quite got warned, but the STL NWS did put out a Special Weather Statement indicating that the storm had low-level rotation, and it sure looked that way to me. Got a couple decent structure pics:
As the meso low left over from the morning action from Tulsa into southwest MO raced through the STL area (and eventually caused some wind damage near the airport), winds backed a little to the southeast of the metro area, creating a little directional shear. And RUC nailed it in its forecast of an area of decent instability tracking from around Monroe and Randolph Counties, IL up toward the Effingham area in the later afternoon/early evening. Not enough for tornades, but definitely enough for a pretty storm.
EDIT - Mods, I see Tom posted his report almost the exact same time I did. Can you merge the two threads for today into one? Thanks!
EDIT2 - I have now posted a fuller report at:
