Western KY has a couple tor warned counties now...

These storms intrigue me. Some good parameters ahead of them. LLJ ahead of them and not bad position relative to RR upper jet quad. Instability / shear looks there.

The RUC and HRRR have helicities increasing significantly over the next couple hours in southern AR spreading northeastward. This is on the nose of an intensifying low-level jet. The tornado threat associated with the storms currently over south-central AR should increase dramatically over the next few hours as they head into SE-E AR/NW MS/SW TN, with significant/violent tornadoes possible.

milam co., tx, cell starting to take on a threatening shape with a nice reflectivity gradient on the southwest side. sitting on the sw end of the line like that, i'd really be worried about that one beginning to spin. golfball-sized hail reported with those cells as well.

And this stuff currently developing over NE TX is only the first wave I think. I like what the HRRR is doing and developing another area of intense convection near the red river valley around midnight as the core of the short wave moves into the more unstable and strongly sheared airmass. Arkansas will have to be on the lookout in the wee hours for round 2 I think.

My understanding is that they should congeal into a line by the time they get into SW TN, however.

My understanding is that they should congeal into a line by the time they get into SW TN, however.

The way it is looking right now there will be multiple waves of supercells popping off the dryline and warm front/dryline intersection through the late afternoon with another significant batch as the upper anomaly ejects into the plains during the evening.

I'd be very cautious about that. Eventually yes, you'll likely see a squall line go through SW TN, but it won't be from the cluster of cells that's in southern AR currently. What's more likely to happen over the next couple hours IMO is that a couple supercells end up becoming dominant, at which point they'll start producing significant tornadoes.

The storms up here in Michigan are finally starting to get their act together. Warnings are out and they're all showing rotation as well.

Unfortunately it'll be several hours before they reach here.

Currently under sv warning here for storms to my sw with wind and hail.. Seems like chicken feed compared to what's going on down south in AR and TX.
