Marine Thunderstorm Wind · Atlantic North

Wind gusts of up to 52 knots (60 MPH) were measured by one of the Solomons Island NOS sensors (SLIM2).

A strong cold front, driven by an unusually strong upper-level trough and wind shear, interacted with a hot, humid, and unstable airmass over the Mid-Atlantic. This pattern resulted in the formation of lines of thunderstorms and several supercells. The most widespread and significant wind damage was noted over northern Maryland, although pockets of considerable wind damage were noted over portions of northwestern Virginia and eastern West Virginia. Somewhat atypical for the Mid-Atlantic is late summer was the number of large hail reports, with multiple instances of giant hail noted.
