SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1136 PM CST Thu Nov 25 2021 Valid 261200Z - 271200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... No thunderstorms are forecast to develop across the contiguous United States on Friday. ...Discussion... Broad upper cyclonic flow will continue over the eastern U.S. Friday, surrounding an evolving low that will shift across the Northeast/New England through the period. In the wake of this feature, lower-amplitude northwesterly flow will evolve with time. The only other feature of interest aloft will be a closed low forecast to migrate across northwestern Mexico, and approach southern New Mexico/far West Texas late. At the surface, a cold front will continue shifting off the East Coast, while lingering across Florida and the Gulf of Mexico. Weak instability ahead of the front, and a stable continental airmass affecting much of the U.S. behind the front, will preclude any appreciable thunder potential through the period. ..Goss/Karstens.. 11/26/2021 Read more LIVE: spc.noaa.gov
