July 4th Thunderstorms Charge Up for 80 MPH Gusts in Virginia and Maryland — SevereWX

Thunderstorms are firing up along West Virginia's high terrain and pushing eastward into Virginia this afternoon, with the Storm Prediction Center (SPC) highlighting a high risk of damaging winds reaching 65-80 mph across much of Virginia, Maryland, and eastern West Virginia.

A Mesoscale Discussion (MD 1491) flags a 95% chance of a Severe Thunderstorm Watch issuance soon. Diurnal heating is supercharging a moist air mass—dewpoints in the upper 60s to low 70s—under steep midlevel lapse rates, fueling thunderstorm development and intensification. Even with modest shear, expect a mix of cells and clusters producing numerous severe gusts.

Peak hail could hit 1.25 inches, but winds are the main story in this holiday setup. Activity peaks through late afternoon, valid until around 3 PM CDT (4 PM EDT).

Impacts: Power outages, downed trees, and holiday disruptions possible in populated areas from Richmond to Baltimore.

SPC coordinates with WFOs in AKQ, LWX, RNK, PBZ, and RLX. Check radar and stay weather-aware.

Preparedness: Secure outdoor items, avoid flooded roads, and monitor NOAA Weather Radio or apps for watches/warnings. Have a severe weather plan ready—your safety first this July 4th.
