Thunderstorms will severe wind gusts and hail will be possible this evening from parts of the Mid-Atlantic into central Appalachians. Isolated severe gusts and hail may also occur in central Wisconsin and in parts of the Northwest. ...Mid-Atlantic/Central Appalachians... An upper-level trough, evident on water vapor imagery, is moving southeastward through the Great Lakes. At the surface, a cold front is advancing southward across the Ohio Valley and central Appalachians. To the south of the front, surface dewpoints are in the upper 60s to lower 70s F. The RAP has MLCAPE in the 1000 to 1500 J/kg range from eastern Kentucky eastward into southern Virginia and across much of North Carolina. Within this area, scattered thunderstorms with an isolated severe threat are ongoing. Forecast soundings in the Mid-Atlantic early this evening have moderate deep-layer shear and steep low-level lapse rates. This suggests the potential for severe wind gusts will continue for a couple more hours with the more organized clusters. ...Central Wisconsin... At the surface, a pocket of moisture and instability is located over central Wisconsin early this evening, where the RAP has MLCAPE in the 500 to 1500 J/kg range. Forecast soundings near the instability max have 0-3 km lapse rates near 7.5 C/km and sufficient deep-layer shear for a marginal severe threat. Isolated severe gusts and hail will be possible for another hour or so. ...Northwest... At mid-levels, a low is evident on water vapor imagery over central California, and flow is from the southeast and east over much of the northwestern U.S. Thunderstorms are ongoing ahead of a band of strong large-scale ascent from far northern California into south-central Oregon. The environment is characterized by moderate deep-layer shear and steep lapse rates, suggesting a threat for isolated severe wind gusts will continue. Additional storms are ongoing near a pocket of moderate instability in northern Idaho and western Montana, where a few severe wind gusts will also be possible. ..Broyles.. 05/28/2026 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
