SPC 0100Z Day 1 Outlook
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. ..Darrow.. 12/23/2025
