Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0627 PM CST Mon Dec 22 2025
Valid 230100Z - 231200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorm probabilities are low tonight.
...01z Update...
Water-vapor imagery depicts a notable short-wave trough advancing
inland along the Pacific Northwest coast. A few flashes of lighting
have been observed with deeper convection ahead of this feature,
primarily across more buoyant regions offshore. While an isolated
thunderstorm can not be ruled out for the next few hours, lightning
probabilities appear too low to warrant a categorical risk of
thunderstorms the rest of tonight.
Lighting has decreased notably across the western Gulf basin in
association with a weak disturbance lifting north toward deep South
TX. 00z sounding at BRO does exhibit uninhibited SBCAPE, but loss of
daytime heating and weak forcing does not appear particularly
favorable for more than a rogue flash of lightning, and that is
primarily over the next few hours.
