Today’s Severe Weather Zone

William’s Severe Weather Zone for Thursday:

Atlantic. A persistent southern stream trough will continue to weaken slowly as subtle, ejecting speed maxima translate from northern Mexico to TX through early Friday. Gradual air mass modification will continue in a return flow regime across the northwest Gulf of Mexico into coastal TX, but negligible forcing for ascent and relatively warm temperature profiles in the mid levels do not support deep convection/thunderstorms within the returning moisture. Isolated lightning flashes may occur farther west near the Rio Grande in the vicinity of the Big Bend late this afternoon into early tonight. However, destabilization will be weak and convective inhibition should be slow to weaken, thus keeping thunderstorm probabilities low and confined to near the international border. ..Thompson.. 12/02/2021 $$
