Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 1244 PM CST Fri Dec 12 2025 Valid 141200Z - 151200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... A few storms are possible across South Florida and the Florida Keys on Sunday. ...Synopsis... An upper trough will move across the eastern CONUS and offshore the Atlantic coast Sunday night/early Monday. At the surface, strong high pressure will continue to build south and east from the Mid-MO Valley to the TN Valley. As this occurs, a weak cold front will move southeast across GA/SC and FL. Richer boundary layer moisture will remain confined to South FL and the Keys where showers and isolated thunderstorms may be ongoing Sunday morning. This activity may persist into the afternoon while shifting southeast with time. Weak instability and modest vertical shear will preclude severe thunderstorm potential. ..Leitman.. 12/12/2025
