SPC 1300Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0626 AM CDT Mon Sep 29 2025 Valid 291300Z - 301200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorm potential is low today and tonight. ...Synopsis... Weak flow aloft and limited large-scale forcing mechanisms will be present today over most of the nation, while an upper trough moves into the Pacific Northwest region. Scattered afternoon thunderstorms will be possible over the central and southern Rockies, and along a cold front as it moves into parts of NV/ID and vicinity. In both areas, limited low-level moisture and weak instability should preclude severe thunderstorm activity. TS Imelda is expected to strengthen off the FL coast today, but remain well offshore. While a few thunderstorms will be possible in distant outer bands from much of FL into the NC/SC/GA coast, the risk of strong/severe storms is low. ..Hart/Grams.. 09/29/2025
