SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0228 AM CST Sun Nov 30 2025 Valid 021200Z - 031200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Scattered thunderstorms are expected through Tuesday across the Southeast to the Atlantic Coastline. The risk for severe thunderstorms currently appears very low. ...Synopsis... A mid-level trough will rapidly traverse the eastern U.S. as another upper trough develops across the Interior West on Day 3/ Tuesday. A surface low, positioned across the southeast U.S., is poised to quickly deepen while ejecting into the Atlantic through the Day 3 period. Strong warm-air advection along the eastern Seaboard will promote a continuous flux of moisture and associated buoyancy ahead of the upper trough. A broad rain shield with embedded thunderstorms will be ongoing across the Southeast on Tuesday morning, and this band will progress eastward to the Atlantic Coast through the day. Some guidance hints at a brief overlap of surface based instability and strong vertical wind shear from a departing low-level jet across south-central/southeastern GA and immediate surrounding areas. If such a high shear/low CAPE corridor can develop, and a stronger thunderstorm tracks through this corridor, large, curved hodographs may support strong low-level rotation. Nonetheless, confidence in this scenario is too low for the delineation of severe probabilities at this time. ..Squitieri.. 11/30/2025
