SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1116 PM CST Sun Dec 07 2025 Valid 081200Z - 091200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe-storm potential appears negligible today through tonight. ...South FL... With a broad upper trough remaining anchored across the East, an embedded shortwave impulse will progress across the southern Appalachians to coastal VA/NC by evening. A surface cold front will sag south across the remainder of the FL Peninsula. In the wake of decaying morning convection, adequate boundary-layer heating will be necessary for redevelopment of midday to afternoon storms along the front. Large-scale ascent, outside of low-level convergence attendant to the front, appears nebulous with the region well-removed from influence of the VA/NC impulse. This combined with persistently weak mid-level lapse rates should limit convective vigor. But a locally strong gust or two might occur until the front progresses into the FL Straits. ..Grams/Thornton.. 12/08/2025
