SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0224 AM CST Mon Dec 01 2025 Valid 031200Z - 041200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are possible over southeast Texas into Louisiana on Wednesday into early Thursday morning. The chance for severe thunderstorms currently appears very low. ...Synopsis... Broad upper troughing will gradually deepen over the central and eastern CONUS through the day Wednesday, resulting in widespread surface high pressure overspreading most of the CONUS. Static stability accompanying this widespread surface high pressure should limit thunderstorm development over most locales. The one exception will be portions of southeast TX into LA, where low-level lee troughing ahead of the upper trough will support the development of a southwesterly low-level jet. Warm-air advection will support both elevated buoyancy and ascent for thunderstorm development through the day Wednesday into early Thursday morning. If a more appreciable surface-based airmass can advect inland, a couple of severe storms cannot be ruled out. However, the confidence in this scenario is currently too low for the introduction of severe probabilities. ..Squitieri.. 12/01/2025
