MORE OF THE SAME CAN BE EXPECTED THE NEXT FEW DAYS AS MOISTURE
INCREASES ON A SOUTHERLY FLOW. THE BEST CHANCE OF SHOWERS AND
THUNDERSTORMS TODAY WILL BE FROM CENTRAL PENNSYLVANIA THROUGH
WESTERN VIRGINIA. FORECASTED BASIN AVERAGED RAINFALL AMOUNTS WILL BE
LESS THAN ONE HALF INCH, BUT POINT AMOUNTS MAY EXCEED ONE INCH.

ANOTHER COLD FRONT WILL APPROACH FROM THE NORTHWEST SATURDAY WITH
MORE ORGANIZED ACTIVITY EXPECTED OVER THE UPPER SUSQUEHANNA BASIN.
BASIN AVERAGED RAINFALL AMOUNTS WILL EXCEED ONE INCH THERE WITH
POINT AMOUNTS OVER TWO INCHES POSSIBLE.

BY SUNDAY, THE COLD FRONT WILL DROP SOUTH WITH THE BEST FOCUS FOR
SHOWERS AND THUNDERSTORMS FROM NEW JERSEY THROUGH VIRGINIA. AGAIN,
BASIN AVERAGED RAINFALL WILL BE OVER ONE INCH WITH POINT AMOUNTS
OVER TWO INCHES POSSIBLE.

ON AREA RIVERS AND CREEKS, GENERALLY MINOR RISES ARE EXPECTED ACROSS
THE BASINS THE NEXT FEW DAYS. IT HAS BEEN DRY AND STREAMFLOWS ARE
LOW, BUT LOCALLY SHARP RISES ARE POSSIBLE ON SMALLER STREAMS AND
CREEKS NEAR STRONGER THUNDERSTORMS.
