A storm looks to be developing on the KDFX radar site. It is located west of Texas over Mexico but will be moving eastward with time. Currently it has 45DBZ along with rapidly rising cloud tops. Conditions are favorable for rapid development of the storm

5000 SB CAPE near the cell in Mexico with over 3500 SB Cape in a large area down in Mexico into Texas.

FL is seeing some action too, such as the severe-warned storm that has golfballs in the warning text and 70 MPH winds. GR3 claims hail size up to 2.75" (now 3.25, 3.50, 2.25 hmm) but I guess one often takes off an inch or so from that estimate, particularly in FL (Melb. met told me usually 50% reduction for hail algorithm FL in warm season), though golf-ball sized hail does fall now and then. Storm is right to the NW of Parklan, FL. Heading NE about 10 mph if anyone is down there. Intense DBZ 70-75. (now down to 65-70)

*First storm has weakened though still officially severe. Another similar storm to the west of that one. Nothing too interesting in terms of tornado potential. Maybe someone will report hail beyond quarter size though as well as some decent gusts if the 70+ verifies. We'll see.

Two weak TVS showing up on GR2AE near Pointe La Hache, LA. This is SRV, MDA algorithm is on GR2 defaults.




Edit: Local law enforcement has reported possible tornado damage according to NWS

Edit: NROT @ 1:06Z from KLIX



1:16Z, KLIX, Base reflectivity - rotation intensifying, and I think I see a hook in there.

As of 01Z RUC/SmartModel still showing pretty good MUCAPE's around 2000 (j/kg), 01-KM EHI still around 1.1, and 0-3Km SRH around 225(m/s) across the SE LA to S. MS areas. Pretty good environment for some spin-ups in those severe cells affecting that region right now. Uploaded city specific severe wx analysis http://smartwxmodel.net/severe.pdf
