A watch will likely be issued in the next hour or so. DISCUSSION...A north/south-oriented broken band of thunderstorms is tracking eastward across central PA, southern NY, and eastern WV at around 30-35 kt. These storms have a history of producing scattered damaging wind gusts and measured gusts upwards of 45 mph. As a low-amplitude shortwave trough continues eastward across western/central PA/NY, this band of storms should progress eastward into eastern PA and vicinity by around 01Z. The downstream air mass is characterized by lower 90s temperatures amid lower 70s dewpoints and steep low-level lapse rates. This environment will remain favorable for damaging wind gusts (50-65 mph) into this evening, especially given the established line of storms and 35-kt unidirectional flow in the lowest 1 km (sampled by the CCX VWP). A watch will likely be issued for parts of the area in the next hour or so. ..Weinman/Smith.. 06/11/2026 ...Please see www.spc.noaa.gov for graphic product...
