SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1014 AM CST Sun Jan 18 2026 Valid 181630Z - 191200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast across the U.S. today or tonight. ...Discussion including South Florida... A longwave trough will remain prominent east of the Rockies, with an embedded shortwave trough crossing the Southeast, in addition to multiple clipper-type troughs over the Upper Midwest. The potential for isolated thunderstorms will exist across the far southern Florida Peninsula and near the Keys to the south of a cold front, somewhat enhanced by diurnal heating and a moist pre-frontal air mass with lower 70s F surface dewpoints. However, most of the thunderstorm potential should focus offshore, and that will particularly be the case by late today as low-level winds veer and the front progresses offshore. ..Guyer/Moore.. 01/18/2026
