515 ACUS01 KWNS 030534 SWODY1 SPC AC 030531 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1231 AM CDT Sat Oct 03 2026 Valid 031200Z - 041200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... No severe thunderstorms are expected across the U.S. today. ... Synopsis ... A midlevel trough and attendant surface cold front are forecast to move east across the upper Mississippi Valley today. Increasing midlevel moisture with the large-scale ascent ahead of the trough, coupled with conditionally unstable midlevel lapse rates, should result in enough elevated buoyancy for thunderstorms across portions of the region. Given the elevated nature of this convection and otherwise limited instability, severe thunderstorms are not anticipated. Farther southeast, a slow-moving front extending from the Carolinas southwestward toward the northwest Gulf will remain a focus for thunderstorm development through the period. Although ample moisture will support thunderstorms along and south of the boundary, generally weak vertical shear and modest lapse rates within the moist thermodynamic environment should limit prospects for organized severe convection. ..Marsh/Halbert.. 10/03/2026 $$
