SEVERE WEATHER OUTLOOK
NATIONAL WEATHER SERVICE STATE COLLEGE PA
1225 PM EDT WED AUG 2 2000

...SEVERE THUNDERSTORMS ARE POSSIBLE ACROSS THE NORTHERN MOUNTAINS
OF PENNSYLVANIA THIS AFTERNOON AND EVENING...

WARM AND VERY HUMID AIR IN PLACE ACROSS THE REGION WILL HELP TO
INTENSIFY AN AREA OF THUNDERSTORMS...WHICH WERE MOVING ACROSS
CENTRAL LAKE ERIE AND NORTHEASTERN OHIO EARLY THIS AFTERNOON.

THE THUNDERSTORMS MAY REACH SEVERE LIMITS AS THEY MOVE INTO THE
NORTHWEST MOUNTAINS NEAR WARREN AND BRADFORD BETWEEN 2 AND 3 PM THIS
AFTERNOON. STRONG WIND GUSTS AROUND 60 MPH ALONG WITH HAIL AND
FREQUENT CLOUD TO GROUND LIGHTNING WILL BE THE MAIN THREAT.

THE THREAT FOR THE SEVERE WEATHER FURTHER EAST WILL OCCUR LATE THIS
AFTERNOON AND THIS EVENING.

THE POTENTIAL ALSO EXISTS FOR LOCALLY HEAVY DOWNPOURS FROM REPEAT
THUNDERSTORMS. THE RAIN MAY BE HEAVY ENOUGH OVER A SHORT PERIOD OF
TIME TO CAUSE FLOODING. PLACES THAT RECEIVED HEAVY RAINS DURING THE
LAST FEW DAYS WILL BE MOST SUSCEPTIBLE TO FLOODING.
