SEVERE WEATHER POTENTIAL OUTLOOK...UPDATE
NATIONAL WEATHER SERVICE PITTSBURGH PA
1110AM EDT WED JUL 23 1997

...THUNDERSTORMS WITH LOCALLY HEAVY RAIN POSSIBLE THIS AFTERNOON
   INTO LATE TONIGHT...

LOW PRESSURE DEVELOPING IN THE CENTRAL OHIO VALLEY WITH A STATIONARY
BOUNDARY ALONG THE MASON-DIXON LINE WILL BRING MOIST UNSTABLE AIR INTO
THE REGION WITH RESULTANT THUNDERSTORMS. ANY THUNDERSTORM THIS
AFTERNOON THROUGH TONIGHT WILL BE SLOW MOVING WITH THE MAIN EFFECT
BEING LOCALLY HEAVY RAINFALLS. IN ADDITION THE REMNANTS OF TROPICAL
SYSTEM DANNY ARE FORECAST TO PASS THROUGH THE VIRGINIAS LATE TONIGHT
AND THURSDAY MORNING WHICH COULD PROVIDE ADDITIONAL MOISTURE TO OUR
REGION.

ALTHOUGH MUCH OF THE UPPER OHIO VALLEY REGION HAS BEEN DRY AS OF LATE
THIS SITUATION COULD RAPIDLY CHANGE WITHIN A SHORT TIME. IT IS
ESTIMATED THAT IT WOULD TAKE NEARLY TWO AND ONE HALF /2.5/ INCHES OF
RAIN IN AN HOUR OR OVER 3 INCHES OF RAIN IN THREE HOURS TO CAUSE POOR
DRAINAGE AND SMALL STREAM FLOODING. THE MOST SUSCEPTABLE AREA FOR
HEAVY RAINS FROM THUNDERSTORMS AT THIS WOULD APPEAR TO BE SOUTH OF
U.S.22 WHERE SOME LOCATIONS CAN GET OVER 2 INCHES OF RAIN IN A COUPLE
OF HOURS.

THE MOST APPROPRIATE ACTION AT THIS TIME WOULD BE TO REMAIN ALERT TO
THE POSSIBILITY OF HEAVY RAINS IF THUNDERSTORMS SHOULD DEVELOP IN
YOUR AREA. KEEP ABREAST OF THE LATEST FORECAST AND LISTEN FOR
LATER STATEMENTS...WATCHES...OR WARNINGS.

SKYWARN/HAM RADIO ACTIVATION IS POSSIBLE LATER THIS AFTERNOON AND
TONIGHT.
