Severe thunderstorms are not expected today through tonight. ...North-central States... Primary thunder potential should occur through about midday in association with a shortwave trough progressing from the Mid-MO Valley to the central Great Lakes. Despite dampening of this wave, sufficient forcing for ascent amid weak elevated buoyancy should yield at least isolated storms centered on the Mid-MS Valley. Modest cloud-bearing shear within the high-based/low-topped convective profile should mitigate severe potential. Farther west-northwest, an upstream shortwave trough will amplify across the Prairie Provinces into the northern Upper Midwest. Sporadic lightning flashes may occur within the attendant warm conveyor ahead of this wave, during the morning into the afternoon. Scant elevated buoyancy will limit storm coverage. Surface-based thunderstorms are unlikely at peak heating along the cold front sweeping east, as boundary-layer moisture is expected to be inadequate for supporting lightning production. ...TX Trans-Pecos... Despite a very weak tropospheric flow regime, a plume of modestly enriched lower-level moisture may be sufficient for isolated, pulse thunderstorms during the late afternoon over the higher terrain near the Big Bend. ..Grams/Marsh.. 10/22/2024 Read more View the full article Quote Link to comment Share on other sites More sharing options...
