SPC 1300Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0654 AM CST Fri Dec 12 2025 Valid 121300Z - 131200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not forecast across the U.S. today or tonight. ...Discussion... Cold/continental trajectories especially east of the Rockies will generally preclude thunderstorm development. Regarding a potential exception, gradual low-level moisture return will continue to occur over the western Gulf toward coastal Texas ahead of a low-latitude trough over northern Mexico. Convection will probably develop and increase late tonight over the western Gulf, but modest forcing for ascent and marginal thermodynamic profiles aloft should limit thunderstorm potential over inland areas of Texas. ..Guyer/Lyons.. 12/12/2025
