SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0127 AM CST Tue Nov 11 2025 Valid 131200Z - 141200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Thursday or Thursday night. ...Discussion... Isolated thunderstorms are possible, mainly on Thursday morning to afternoon, from central CA to western OR. Embedded within a broader upper trough initially off the West Coast, a leading shortwave impulse should eject northeast and move inland by Thursday night. The attendant low-level warm conveyor will be most pronounced Thursday morning before diminishing as it separates southward in CA. While a few lightning flashes are possible amid flimsy instability within this regime, mid-level lapse rates will steepen in its wake with approach of the cold core. This should focus isolated, low-topped thunderstorms from northern CA through western OR on Thursday afternoon. Small hail may accompany a storm in the northern Sacramento Valley but scant buoyancy should limit severe potential. ..Grams.. 11/11/2025
