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.
