878 ACUS02 KWNS 061715 SWODY2 SPC AC 061713 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1213 PM CDT Wed May 06 2026 Valid 071200Z - 081200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER PARTS OF THE SOUTHEAST...AND IN TEXAS NEAR THE MIDDLE RIO GRANDE VALLEY... ...SUMMARY... A few strong to severe thunderstorms are possible Thursday across portions of the central Gulf coast into South Carolina. Isolated large hail is possible over a small part of Texas near the middle Rio Grand Valley. ...Synopsis... An upper trough will move from the Great Lakes into the Northeast on Thursday, with leading speed max aloft sweeping across the TN Valley and toward the Mid Atlantic. At the surface, a cold front will push south across the Carolinas, with western portions of the front stalling near the central Gulf Coast. To the west, strong southwest winds aloft will persist from northern Mexico into TX as an upper low drifts east, with high pressure at the surface but elevated instability in place. ...Southeast... Scattered thunderstorms will likely be ongoing near the cold front Thursday morning, from southeast LA across GA and into the Carolinas. A few storms could still be severe from southeast AL into central GA as the previous nights activity persists. Strong wind gusts or even a brief tornado cannot be ruled out at that time as SRH will be maximized above 200 m2/s2. Given the veering low-level winds with time and associated midlevel drying/subsidence later in the day, the severe risk may diminish by afternoon. ...Middle Rio Grande Vicinity... While lift will be weak, it appears enough lift via warm advection above the stable surface layer may support isolated storm development early on Thursday. Winds around 850 mb will be out of the southeast at 10-15 kt, with indications by some models of hail potential. Uncertainty exists regarding degree of elevated instability, but effective shear in the cloud-bearing layer conditionally favor hail. ..Jewell.. 05/06/2026 $$
