SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0231 AM CST Tue Jan 27 2026 Valid 291200Z - 301200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are unlikely Thursday. ...Synopsis... Broad-scale troughing will continue across the eastern half of the US as the primary upper trough moves off the East Coast into early Friday. At the same time several shortwave perturbations, emanating from southern Canada and the central Rockies respectively, will begin to converge and strengthen over the central US. In the wake of these systems, ridging will build over the West supporting continued strong northwesterly flow aloft. A cold front and Arctic high pressure will move south forcing offshore flow over the CONUS. This will again negate thunderstorm potential through the forecast period. ..Lyons.. 01/27/2026
