Anyone noticing the storms popping up ahead of the line SW of Tuscaloosa? Have to keep a close watch on those if they don't merge with the main line.

The storms have slowed down as well....I've still not seen the sounding, have you? Anyone? Was there any difference?

The problem continues to be unidirectional flow. Discrete cells might have a downdraft/hail component but anything more is VERY low. You can see the flow in the lowest 1km is NOT conducive for tornadic storms at all.

Lesson for today....if you're gonna have SW to SSW surface winds, need more westerly component in the mid levels and WNW in the upper levels. Just as I thought this morning, the unidirectional nature reduced curved inflows and coherent RFDs.

NWS Paducah upgraded the Perryville, MO tornado to EF4. 180mph winds
Yes.....about what I expected. My personal estimate after seeing the tornado damage close up today on my friend's (Mike Phelps) live stream was 170-180 mph between Ava and Vergenee, IL.
