Severe thunderstorms are not currently forecast for Tuesday. However, a few strong storms cannot be ruled out across the Ohio Valley and the southern Rockies. ...Southern Rockies to the OH Valley... An upper trough extending from Hudson Bay toward the Upper Midwest will shift east on Tuesday, crossing the Great Lakes and Ohio Valley. At the surface, a cold front will extend from southern Lower MI toward central TX during the morning. The front is expected to develop east/southeast through the period, positioned from New England toward the Deep South and South TX. A rather moist airmass for this time of year will be in place ahead of the front, with surface dewpoints in the low to mid 60s F common from central TX into the Lower OH/TN Valleys. This will aid in pockets of modest destabilization (500-1000 J/kg MLCAPE). However, stronger destabilization will be limited due to poor lapse rates, cloud cover, and areas of ongoing showers/thunderstorms at the beginning of the period. While effective shear magnitudes up to 30 kt are expected, deep layer flow parallel to the surface boundary will favor line segments. Where stronger destabilization can occur, particularly near the Lower OH Valley vicinity, isolated gusty winds could accompany any stronger cells/line segments. Additional storms are expected in a post-frontal regime across NM into the OK/TX Panhandle vicinity. Deep-layer flow will be weaker here, and lapse rates/instability will remain modest, limiting severe potential. Nevertheless, gusty winds and perhaps small hail could accompany the stronger cells, but severe potential appears low. ..Leitman.. 10/06/2025 $$
