THERE IS A MODERATE RISK THAT THUNDERSTORMS WILL BE SEVERE THIS AFTERNOON AND TONIGHT. ANY THUNDERSTORMS CAN PRODUCE DAMAGING WINDS...LARGE HAIL...AND FLOOD PRODUCING RAINFALL.

COUNTIES IN SOUTHERN PARTS OF EAST CENTRAL OHIO AND EXTREME NORTHERN WEST VIRGINIA ARE UNDER THE THREAT SEVERE THUNDERSTORMS THROUGH MUCH OF THE AFTERNOON.

EXTREME NORTHERN WEST VIRGINIA INCLUDING THE PANHANDLE AND EXTREME WESTERN MARYLAND THROUGH 10 PM TONIGHT. THE CAUSE OF THIS POTENTIAL FOR SEVERE STORMS IS A COMBINATION OF VERY HUMID AIR IN THE LOW LEVELS...AND INCREASING WINDS ALOFT...DUE TO AN APPROACHING UPPER LEVEL JET STREAM. A SURFACE LOW PRESSURE CENTER MOVING THROUGH THE EASTERN GREAT LAKES THIS AFTERN OON AND TONIGHT WILL BE DEVELOPING A COLD FRONT OVER NORTHWEST PENNSYLVANIA. THIS FRONT COULD FOCUS WHERE THE FIRST STORMS DEVELOP THIS AFTERNOON. LISTEN TO NOAA WEATHER RADIO FOR UPDATES.
