SPC 1730Z Day 2 Outlook Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1228 PM CDT Sat Oct 02 2021 Valid 031200Z - 041200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE LOWER OHIO AND WESTERN TENNESSEE VALLEYS... ...SUMMARY... Thunderstorms associated with strong wind gusts will be possible across parts of the lower Ohio and western Tennessee Valleys Sunday afternoon. ...Lower Ohio and western Tennessee Valleys... An upper-level trough is forecast to move eastward across the lower Ohio and western Tennessee Valleys on Sunday, as a cold front advances eastward across the mid Mississippi Valley region. Substantial cloud cover and morning showers/thunderstorms will temper daytime heating, however sufficient heating of surface dew points in the 65-70 degree range will result in a corridor of greater destabilization with MLCAPE in the 1250-1750 J/kg range by afternoon. Mid-level southwesterly flow will contribute to effective shear values ranging from 25 to 30 kts, sufficient for multicell storms during the afternoon. Isolated stronger storms may pose a risk for strong/locally damaging gusts. ..Bunting.. 10/02/2021 Read more LIVE:
