SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1230 AM CST Sat Jan 17 2026 Valid 181200Z - 191200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Sunday. ...Synopsis... An upper trough will move across the eastern U.S., moving offshore the Atlantic coast Sunday night. Meanwhile, broad upper troughing will be maintained across much of the CONUS, reinforced by shortwave impulses over the northern Rockies and Upper Midwest. At the surface, a cold front will move southeast across the FL Peninsula through the afternoon, while a second cold front moves southeast across parts of the Midwest and Plains overnight. A dearth of boundary layer moisture and a cold/stable airmass will preclude thunderstorm activity across most of the CONUS. The exception may be across portions of the southeast FL Peninsula and the Keys. Modest boundary layer moisture will support weak buoyancy near the coast and just offshore as the upper trough and surface front provide forcing for ascent. A few lightning flashes are possible, but the bulk of thunderstorm activity is expected to remain offshore where better instability will support deeper updrafts. ..Leitman.. 01/17/2026
