DISCUSSION...Near-term damaging wind threat is focused along a short west/east-oriented multicell cluster progressing south-southeast near the PA/MD/WV border area. Reported tree damage with the cluster has been aided by a belt of moderate mid-level northwesterlies well sampled by the PBZ VWP. Surface temperatures are quite warm ahead of the cluster. This will support continued strong gusts even as convection spreads south of the relative peak in MLCAPE across southwest PA earlier.=20 Farther east in south-central to southeast PA, lower-topped discrete cells are ongoing. Weaker and a more west-northwesterly component to mid-level flow per the CCX VWP suggests this activity may struggle to organize. Still, with low to mid 90s surface temperatures common over the Piedmont to Coastal Plain, potential will exist for a few microbursts and a localized damaging wind threat as this activity spreads east-southeast through early evening. ...Grams/Mosier.. 08/17/2025 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!96PNspZ0Ohy0fgF_fm8xxVupHyB5r9JKskRjejIC1n9_ayuC2SOiljOrVNrLtEVdCxFaS8r5O= Om-toTRCGsC3iMfDj8$ for graphic product...
