829 ACUS03 KWNS 241907 SWODY3 SPC AC 241906 Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0106 PM CST Mon Nov 24 2025 Valid 261200Z - 271200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe storms are not forecast on Wednesday or Wednesday night. ...Synopsis... An amplified shortwave trough will further deepen as it swings across the Great Lakes into the Saint Lawrence Valley. Associated deep surface cyclone will track across the central Great Lakes to the Ottawa Valley. Downstream frontal occlusion should arc to a weaker low moving across New England, with the leading cold front trailing southward and exiting much of the Atlantic Seaboard by Wednesday night. ...East... Surface-based thunderstorm coverage along/ahead of the aforementioned front is expected to remain sparse on Wednesday, limiting unconditional severe probabilities. Instability should be weak north of south GA/north FL, where strong deep-layer shear will be prevalent ahead of the aforementioned front. Rather low-topped convection may precede the most pronounced mid-level DCVA in the western/upstate NY vicinity on Wednesday afternoon. While it may be insufficient to produce lightning amid flimsy buoyancy, it could be accompanied by strong gusts along a secondary surface frontal surge with a strengthening pressure gradient in its wake. ..Grams.. 11/24/2025 $$
