Appalachian Thunderstorms Primed for 70 MPH Gusts, Quarter-Size Hail — SevereWX

Scattered thunderstorms are firing up across the Appalachians this early afternoon, packing the punch of severe wind gusts up to 70 mph and hail to 1.25 inches.

The Storm Prediction Center's Mesoscale Discussion 1087 highlights a subtle upper-level impulse over western Lake Erie combining with hot, humid conditions—temps in the low to mid-80s and dewpoints near 70°F. This setup is fueling rising instability with CAPE exceeding 2000 J/kg and enough shear (20-25 knots) for storm organization.

Primary risks include downburst winds from stronger storm cores or merging outflows, especially as heating peaks. Hail remains possible in this moist environment, though limited shear keeps it on the smaller side.

Impacts stretch from eastern Ohio and western Pennsylvania, through much of West Virginia, into western Maryland and north-central Virginia. A severe thunderstorm watch issuance looks likely within the next couple hours to cover peak storm development through late afternoon.

Peak wind gusts could hit 55-70 mph, snapping tree limbs and downing power lines. Stay tuned to local NWS updates from offices like Pittsburgh (PBZ), Cleveland (CLE), Charleston (RLX), and others.

Prep now: Review your severe weather plan, secure outdoor items, and monitor radar via apps like RadarScope or NOAA Weather Radio. If storms approach, seek shelter away from windows.
