Scattered severe storms with wind damage, large hail, and a few tornadoes will be possible Friday afternoon through late Friday evening across parts of the Mid-Atlantic and Southeast. ....Mid-Atlantic and Southeast... Pattern amplification will occur Friday as one shortwave trough progresses from the Mid-South to the southeast Atlantic/Mid-Atlantic coast, in advance of another wave digging southward over the Great Lakes. An associated surface cyclone will develop east-northeastward across the Mid-Atlantic late Friday and to the southern New England coast by Saturday morning, while a trailing cold front crosses the Gulf coast, north FL and the southeast Atlantic coast. Within cloud breaks the warm sector will consist of afternoon temperatures near or above 80 F and boundary-layer dewpoints in the 60s, which will drive MLCAPE of 1000-2000+ J/kg and minimal convective inhibition by early-mid afternoon. Increasing midlevel flow with time and forcing for ascent along and just ahead of the front will support storm initiation with the potential for storm clusters and some supercells capable of producing damaging winds, large hail and a few tornadoes. If wave timing and thermodynamic profiles remain favorable, some portion of this area may warrant an upgrade in later updates. ...Thompson.. 05/28/2025 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
