INTENSE supercells in deep south Texas moving SSE likely producing hail larger than baseballs and even a brief tornado threat. The tornado warning earlier for just south of Pearsall, TX was allowed to expire. The storm north of Del Rio likely will intensify rapidly over the next hour.

SEVERE WEATHER SETUP TODAY: Dominator team chasing extreme northwest Oklahoma where we anticipate 1-2 intense SE moving #supercells, with very large #hail. providing live coverage for KFOR-TV and Mike Morgan if severe weather strikes. We'll be streaming live along with other TVN chasers in our network later this afternoon on http://tvnweather.com/live A conditional #tornado threat exists given air mass recovery and interaction and outflow boundary (OFB) left behind by overnight storms.

Atlantic hurricane season could be getting started with a tropical wave halfway between the Lesser Antilles and western Africa with a 70% chance for tropical cyclone development given by the NHC. Most forecast models take this storm toward the Lesser Antilles, and while anything can happen thereafter, a few of the models are eventually taking this storm toward the southeast U.S. Coast. We'll keep you updated on the status of this storm.

NAM forecast model showing marginal supercell threat in North Texas including DFW area IF storms can develop given strong cap and likely limited moisture return, and subtle low-amplitude trough. If storms do develop by late afternoon/evening though, they likely will be supercells and pose even a non-zero tornado threat. Models are all over the place these days, so stay tuned for updates.

More severe weather as supercells develop along a dryline with very strong instability in western OK, northwest TX, southwest KS with very large hail the main threat.. However, wind shear will ramp up near or after sunset so any isolated storms that sustain into late evening will have tornado potential. it doesn't feel quite right to be chasing, but I know Tim, Carl, and Paul would want us out there..

Severe thunderstorm warnings for Atoka, Bryan, Coal Haskell, Muskogee, Pittsburg and Sequoyah counties in Oklahoma! Quarter size hail and damaging winds are likely! These storms are moving at 55 mph to the NE! There's also some concern for isolated supercells to develop ahead of the main line in the image circled. Stay tuned.

Severe weather and possible tornadoes in the south, especially across southern AL into southwest GA later this afternoon! Blizzard conditions in the northern Plains, and an intensifying coastal storm could drop 10-18" of new snow in the mountains of New England. The CHAOS continues into March! STAY SAFE and stay tuned for updates. We'll be issuing a severe wx bulletin later this afternoon on http://tvnweather.com/bulletins

Severe weather likely, including isolated tornadoes, especially South Carolina, North Carolina, Virginia, possibly farther north given high wind shear values ahead of potent short-wave trough. Stay tuned to local watches and warnings in these areas, have your NOAA weather radios charged, and be proactive in finding a shelter and having an action plan should severe weather strike. Stay safe today.
