524 ACUS01 KWNS 100051 SWODY1 SPC AC 100049 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0649 PM CST Tue Dec 09 2025 Valid 100100Z - 101200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not forecast through tonight. ...Discussion... A fast moving surface low, associated with a strong mid-level jet streak, will continue to move east-southeastward toward the western Great Lakes this evening. Forecast soundings show some very weak elevated instability within the warm sector, but it does not appear instability will be deep enough for sufficient charge separation for any thunderstorm activity. Elsewhere in the CONUS, thunderstorm activity will be minimal without significant instability in place. Some lightning has occurred south of the Florida Keys, in the vicinity of the stalled surface front. However, the lightning activity has remained well offshore and is expected to remain so. ..Bentley.. 12/10/2025 $$
