SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0228 AM CST Fri Dec 19 2025 Valid 211200Z - 221200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Organized areas of thunderstorms are not expected on Sunday. ...Synopsis... An upper-level trough over the Northeast U.S./Quebec Province will move east on Sunday, as an upstream upper trough approaches the Pacific Northwest coast. A surface cold front will move across the eastern/southeast U.S. as an expansive high pressure system becomes established behind the front. Generally weak buoyancy may develop near the TX and LA coastal areas where heating of 60s surface dew points takes place, however little in the way of large-scale ascent is expected in this region. Thus, while an isolated thunderstorm will be possible across the lower MS Valley in the vicinity of the front, the overall potential for thunderstorms appears too limited for the introduction of a 10 percent area with this outlook. ..Bunting.. 12/19/2025
