056 ACUS01 KWNS 271622 SWODY1 SPC AC 271620 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1020 AM CST Thu Nov 27 2025 Valid 271630Z - 281200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Organized severe thunderstorms are not forecast through tonight. ...Synopsis and Discussion... A large-scale upper trough encompassing much of the central/eastern CONUS will develop slowly eastward through the period. Isolated thunderstorm potential today will generally remain limited to parts of south FL and the Keys along/ahead of a southward-moving cold front. 11/12Z soundings from XMR/TBW/KEY show southwesterly winds strengthening with height at mid/upper levels. While sufficient deep-layer shear may exist to support a stronger thunderstorm or two this afternoon, especially along the Atlantic Coast in south FL, the presence of poor mid-level lapse rates and weak low-level winds should hinder the risk for organized severe thunderstorms over land. Isolated lightning flashes may also occur with snow bands occurring in western NY off of Lake Ontario. ..Gleason/Wendt.. 11/27/2025 $$
