Scattered strong to locally severe storms are expected on Tuesday from parts of the southern Plains eastward into the Southeast. The greatest threat of large hail or wind damage will be over parts of southwest Texas. ....Synopsis and Discussion... An upper low will remain over the northern Plains on Tuesday, with modest west/southwest flow aloft stretching from the southern Plains and across the TN/OH Valleys. High pressure will remain over the northern to central Plains, upper MS Valley and Great Lakes, limiting northward moisture return at the surface. A zone of moderate to strong instability will remain on Tuesday from much of TX eastward along the Gulf Coast states, with an effective east-west boundary pushing south each day due to multiple rounds of storms and outflows. Scattered storms may be ongoing roughly from northeast TX into TN Tuesday morning, with various outflows spread southeastward across the region, aiding new daytime development. Locally damaging gusts will be the primary concern. Farther west, severe storms chances appear greater, as easterly surface winds bring a moist air mass far westward into a region of steep lapse rates. Although midlevel winds will not be strong, the combination of deep low-level easterlies and good high level flow may support scattered severe storms in clusters, with hail and wind potential as instability will be strong and over 3000 J/kg MUCAPE. ...Jewell.. 05/25/2025 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
