Isolated severe thunderstorms are possible across parts of the North-Central States on Wednesday into Wednesday night. ....North-Central States... Low probability severe potential remains evident across the region with multiple scenarios anticipated amid fairly nebulous large-scale ascent. Initial threat should be in the southeastern lobe across the Lower MO Valley vicinity with potential for an ongoing MCS. As with evolution of such an MCS but the overall signal is for a weakening trend after 12Z. A distinct minority of guidance indicates some potential for diurnal intensification with a remnant MCV. Sporadic strong gusts capable of localized damage seems plausible in the morning and perhaps into the afternoon. Conditionally, the most favorable environment for severe should be across the Black Hills vicinity and the NE Panhandle as convective outflow from late D1 is pushed south into the central High Plains. North of this outflow, a moderately supportive supercell environment should exist. At least isolated thunderstorms should develop late afternoon to early evening. But low-amplitude ridging between a shortwave trough in the southern Canadian Prairies and a minor trough in the Northwest should modulate overall coverage. Isolated large hail and severe gusts should be anticipated into late evening. Downstream low-level warm theta-e advection should be centered over the Mid-MO to Upper MS Valleys on Wednesday night where a few marginally severe storms are possible. A few strong storms may also occur across northern MN during the afternoon, owing to trailing influence of the southern Canadian Prairies wave. Scattered storm coverage should be confined along the international border, but modest mid-level lapse rates should temper convective vigor. ...Grams.. 08/05/2025 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
