Violent tornado with that Byhalia MS cell. 80 kt VROT, huge TDS.

Large tornado moving directly into Selmer TN, pop nearly 4500, this could be bad.

And another strong tornado near Senatobia MS.

Strong tornado in progress near Middleton TN currently, perfectly discrete supercell.

Warehouse collapsed with people trapped near Brownsburg IN (west side of Indy) from the tornado earlier.

This ACARS profile from St. Louis is bad news from E MO/central IL should any storms get loose ahead of the line. Extremely favorable hodograph for tornadic supercells and a weakening cap.

IN/W OH may have some issues later.

Tomorrow could be a very serious severe weather event across KS and southward into OK, particularly in the evening. Incredible shear profiles will overlap with rapidly returning moisture along a 50-70 kt LLJ and weak CIN ahead of a rather potent dryline.

12z Euro is also a major event. Very volatile parameter space across a very large area with relatively subtle forcing for ascent and a weak cap is a recipe for trouble.

Really, really need a thread for 4/2-3 here soon. Major outbreak on the 12z GFS from IL/IN all the way southward to central MS.

Could be a pretty nasty nocturnal threat with this one especially closer to the Ohio River.

Volatile, potential widespread severe setup on the 12z Euro/EPS/AIFS next week around 4/2 @RCNYILWX. Have seen that synoptic pattern before and it's consistent with significant GL/Midwest/OV severe events. This has been showing up for several runs now while the GFS is off in la-la land.

Moisture is mixing out too much, temperatures getting too warm.

Pretty much a no-brainer on the 21z RAP. There's enough columnar CAPE for robust updrafts as well.

The LCLs on the 15z RAP and 18z HRRR are plenty workable for some tornadoes should the thermodynamics verify this way.
