681 ACUS02 KWNS 111658 SWODY2 SPC AC 111656 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1056 AM CST Thu Dec 11 2025 Valid 121200Z - 131200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... The risk for thunderstorms appears negligible across much of the U.S. Friday through Friday night. ...Synopsis... An upper ridge will persist near the Pacific coast while broad upper troughing continues across the eastern U.S. Stronger flow aloft will be displaced from the only appreciable, albeit modest, moisture along the Texas coastal plain. A surface low over the OH/TN Valleys will shift east toward the Mid-Atlantic late in the period, allowing a weak cold front to develop south toward the western and central Gulf coasts. Some thunderstorm activity could develop late in the period over the western Gulf waters as a weak shortwave impulse moves across northeast Mexico. However, thunderstorm activity is expected to remain offshore, precluding 10 percent general thunder probabilities. ..Leitman.. 12/11/2025 $$
