Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1156 PM CST Wed Nov 12 2025 Valid 131200Z - 141200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Minimal thunderstorm chances are evident today over parts of central California. Severe weather is not forecast. ...Synopsis... An upper low within a positive-tilt upper trough will slowly move eastward toward the West Coast today, with abundant midlevel moisture and lift overspreading much of CA. Within the moist plume, forecast soundings indicate minimal instability during the day, mostly elevated in nature. Despite strong veering wind profiles with height, shear is expected to be ineffective as SBCAPE remains near zero. Elsewhere, an upper trough will remain over the eastern states with northwest flow from the Plains across the MS Valley. A surface high will remain over much of the east, with little to no instability for thunderstorms. ..Jewell.. 11/13/2025
