168 ACUS02 KWNS 071731 SWODY2 SPC AC 071729 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1229 PM CDT Tue Oct 07 2025 Valid 081200Z - 091200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Organized severe thunderstorms are not currently expected on Wednesday. ...Synopsis... An amplified mid/upper-level trough initially extending from eastern Canada into the Northeast and Ohio Valley will move eastward through the period. A cold front will move through New England and the Mid Atlantic during the day, and reach parts of the Southeast by evening. In the wake of the trough, an upper-level ridge will begin to amplify across parts of the southern/central Rockies and High Plains. West of the amplifying ridge, a mid/upper-level trough will deepen in place near the Pacific Coast and adjacent eastern Pacific, as an embedded deep-layer cyclone moves southward off of the Pacific Northwest coast. ...Northern Mid Atlantic into southern New England... Low-topped convection will move through parts of the northern Mid Atlantic and southern New England during the morning, in conjunction with the cold front. While much of this convection may produce little or no lightning, strong deep-layer flow and some enlargement to low-level hodographs could support gusty winds and weak rotation with the stronger convective elements. At this time, instability appears too meager to support an organized severe threat. ...GA into the Carolinas and southeast VA... Isolated to widely scattered storms will be possible during the afternoon and evening from parts of GA into the Carolinas and southeast VA, along and ahead of the cold front. Midlevel flow will initially be modestly enhanced along the southern periphery of the departing mid/upper-level trough, though may tend to weaken through the day. With poor midlevel lapse rates, weak buoyancy, and generally weakening low-level flow with time, organized severe potential appears low, though locally gusty winds could accompany the strongest storms. ...Eastern AZ into western NM... Scattered afternoon/evening storms will be possible from eastern AZ into western NM on Wednesday, potentially developing as far north as the Four Corners region. Some warming of midlevel temperatures and weakening of midlevel flow/deep-layer shear are expected compared to D1/Tuesday, due to the influence of the building upper ridge. This should tend to limit storm organization and intensity, though locally gusty winds and small hail will be possible. ..Dean.. 10/07/2025 $$
