Subj : DAY2SVR: Nws Storm Prediction Center Norman Ok To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Sat Nov 15 2025 05:14:08 ACUS02 KWNS 150514 SWODY2 SPC AC 150512 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1112 PM CST Fri Nov 14 2025 Valid 161200Z - 171200Z ....NO SEVERE THUNDERSTORM AREAS FORECAST... ....SUMMARY... Isolated thunderstorms are possible from the Lower Colorado River Valley into the Four Corners states on Sunday. Additional isolated thunderstorms may approach the central California coast early Monday morning. Severe storms are not expected. ....Western U.S... An upper low and attendant trough over the western Great Basin and Southwest states will pivot east/northeast toward the Rockies and adjacent High Plains on Sunday/Sunday night. Moderate southwesterly deep-layer flow ahead of this feature will overlap with midlevel moisture and cooling aloft to provide weak instability. Isolated thunderstorms will be possible from the Lower CO Valley into the Four Corners states through evening as the upper trough progresses east/northeast. A cool boundary layer and MLCAPE less than 500 J/kg will preclude severe potential. Another upper low offshore the Pacific coast will develop southeast toward the northern/central CA coast last Sunday/early Monday. Cooling aloft will allow for development of weak instability near the central CA coast as a weak surface low and Pacific front move inland near around 08-12z Monday. Low-topped convection may produce isolated lightning flashes while 25-35 kt southwesterly low-level flow could foster locally gusty winds. Poor lapse rates and meager instability will preclude severe thunderstorm potential. ...Leitman.. 11/15/2025 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
