NWS Storm Prediction Center Norman OK
0652 PM CST Wed Dec 31 2025
Valid 010100Z - 011200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms may occur across parts of southern California
late tonight.
...01z Update...
Well-defined upper low is lifting northeast toward the southern CA
coast as a 500mb speed max translates into the base of the trough,
but remaining offshore. Left exit region of this jet will encourage
convection along the weak front as it surges toward the coast late
tonight. Primary concern for lightning will be after 09z, but this
activity will be elevated and within a poor instability environment.
Severe risk appears minimal tonight.
