Excerpted from the National Weather Service:
The NWS Storm Prediction Center has issued a
Severe Thunderstorm Watch for portions of
Western Maryland
Far Eastern Ohio
Western and Central Pennsylvania
Northern West Virginia

Primary threats include…

SUMMARY…Thunderstorm coverage is expected to increase this afternoon in the vicinity of a cold front moving southeastward across the area. Environmental conditions favor initially discrete storms, with some supercells possible. Large to isolated very large hail is the primary risk with any supercells. A trend towards a more linear mode is anticipated with time, with the primary hazard transitioning to strong gusts. A tornado or two is also possible, but limited low-level moisture and high LCLs should keep the overall tornado probability low.
The severe thunderstorm watch area is approximately along and 60 statute miles north and south of a line from 40 miles west of Wheeling WV to 35 miles east northeast of Harrisburg PA. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU2).
