SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1103 AM CST Sat Jan 17 2026 Valid 181200Z - 191200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Sunday. ...Synopsis... Thunderstorms are not expected for much of the country on Sunday with the exception of the southern FL coast. A cold continental air mass is noted in mid-morning surface observations surging southward across the Plains in tandem with an upper wave/jet. These features will shift southeastward into the northeastern Gulf by 12z Sunday, and will likely support an uptick in anafrontal stratiform precipitation across the Southeast states through the day. However, negligible buoyancy is expected owing to poor lapse rates and modest low-level moisture, which should preclude thunderstorm development. Isolated thunderstorms appear possible along and just off the southern FL Atlantic coast Sunday afternoon within a weak warm advection regime ahead of the primary cold front. Offshore storm motions should further limit the duration of convection over land. ..Moore.. 01/17/2026
