ACUS02 KWNS 280610 SWODY2 SPC AC 280609 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 0109 AM CDT Mon Apr 28 2025 Valid 291200Z - 301200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS PORTIONS OF EASTERN OHIO INTO THE LOWER GREAT LAKES REGION... ...SUMMARY... Scattered severe thunderstorms are likely across parts of the Lower Great Lakes on Tuesday afternoon/evening. Scattered severe thunderstorms are possible southwestward into the southern Great Plains. Isolated significant-severe potential, mainly from hail, is apparent across west Texas and separately in parts of the eastern Midwest to Lower Great Lakes. ...Synopsis... A consolidated shortwave trough will move eastward across the Great Lakes and southeast Canada on Tuesday. A southern-stream trough over the Southwest to northwest Mexico should drift east. Primary surface cyclone over northeast ON should quickly progress towards the Canadian Maritimes. An attendant cold front will push across the central to Lower Great Lakes Tuesday afternoon and evening. A weaker surface low should remain anchored over the TX Trans-Pecos. ...Eastern Ohio Valley/Lower Great Lakes... Ahead of the cold front, the warm sector across the Ohio Valley into the Lower Great Lakes region should destabilize through the morning/early afternoon. Initially, storms will develop across eastern Ohio into the Lower Great Lakes near the aforementioned surface low/cold front interface. Large hail will be the initial threat with supercell modes before a tendency to cluster and grow upscale. This will bring an increase in the potential for scattered to widespread damaging wind as the front shifts eastward with bowing line segments/clusters through time. ...TX/OK... A secondary weaker surface low will develop across western Texas near the vicinity of the dryline and a stationary front across portions of central Oklahoma into southern Kansas Tuesday afternoon. This region will be the focus of supercell development by the afternoon, with potential for large to very large hail, severe wind, and a tornado. An Enhanced Risk for hail may be needed in further outlook updates, given the steep lapse rates and supercellular modes, but uncertainty on coverage warrants re-evaluation as mesoscale details become more clear. ..Thornton/Bentley.. 04/28/2025 $$ |
