SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0110 PM CST Mon Jan 12 2026 Valid 141200Z - 151200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorm potential appears low on Wednesday. ...Synopsis... A deep upper trough will remain in place across the central/eastern CONUS on Wednesday. Within the large-scale trough, embedded shortwave troughs will move through parts of the Midwest/Great Lakes, central Gulf Coast/Southeast, and the Florida Peninsula. A surface low initially over Quebec will move quickly northeastward, with new surface low development expected near southern New England later in the period, and frontal wave development possible offshore of the Atlantic Seaboard. A reinforcing cold front will move through much of the central/eastern CONUS through the period. With the exception of south FL, prefrontal moisture return is expected to be too meager for appreciable destabilization. Across south FL, weak buoyancy may be in place Wednesday morning, but most guidance suggests that thunderstorm potential will largely be offshore by the start of the period (12Z Wednesday morning). Late in the period, weak convection associated with the approaching shortwave trough and cold front may affect parts of the FL Peninsula, but forecast buoyancy by late Wednesday night/early Thursday morning appears too weak/shallow for appreciable thunderstorm potential. ..Dean.. 01/12/2026
