Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1001 AM CST Sat Jan 17 2026 Valid 171630Z - 181200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not forecast across the U.S. today or tonight. ...Discussion... Deep convective potential will remain virtually nil through tonight as a longwave trough persists east of the Rockies, with an embedded shortwave trough amplifying over the Lower Missouri Valley/Ozarks and Midwest. At the surface, a cold front will continue southeastward and clear much of the coastal Southeast except the Florida Peninsula by tonight. Near/ahead of the front, even with some late-day moisture increase across the Peninsula, poor lapse rates aloft are expected to limit thunderstorm potential. ..Guyer.. 01/17/2026
