Areas affected...parts of WV...eastern OH...and western PA

Concerning...Severe potential...Watch possible 

Valid 051702Z - 051900Z

Probability of Watch Issuance...60 percent

SUMMARY...At least isolated severe hail and damaging winds will be
possible this afternoon from parts of West Virginia across the Upper
Ohio Valley towards Lake Erie. Monitoring for a potential severe
thunderstorm watch across parts of the region.

DISCUSSION...Isolated thunderstorms have gradually developed across
far southern WV, within the left-exit of a mid-level jetlet curling
north, east of the southern Appalachians. Scattered showers are also
prevalent from northern VA into western PA beneath a separate
upper-level jetlet. Closer to the cold-core of the OH Valley
mid-level low, convective temperatures have been breached across the
Upper OH Valley. This suggests ongoing cells in southern WV should
intensify/increase in coverage by mid-afternoon as they spread
north-northwestward, yielding a corridor of severe hail/damaging
wind potential. Farther north, greater cloud coverage/ongoing
showers may result in a more marginal/sporadic hail/wind threat.
