AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PITTSBURGH PA 214 PM EDT FRI MAY 9 2003 THIS MORNINGS HEAVY RAIN HAS STABILIZED THE ATMOSPHERE AND THE WARM FRONT STAYED TO OUR WEST AND SOUTH. AS A RESULT...OUR PROBLEMS TODAY WERE WITH FLOODING AND NOT SEVERE STORMS. RAINFALL WAS BETWEEN ONE AND TWO INCHES WITH THE HIGHER AMOUNTS GENERALLY SOUTH. I LEFT A CHANCE OF STORMS IN THE OVERNIGHT PERIOD AS THE WARM FRONT SHOULD SLOWLY MOVE THROUGH THE AREA GIVING US A SUMMERLIKE DAY ON SATURDAY. RLX WILL BE ISSUING A FLOOD WATCH FOR SATURDAY ALONG OUR BORDER COUNTIES AND WE WILL BE LOOKING AT THAT SITUATION SHORTLY. THE FOCUS THEN SHIFTS TO SATURDAY NIGHT AND SUNDAY AS THE MIDWEST LOW DEEPENS AND ROCKETS A POTENT COLD FRONT TOWARDS OUR AREA. LOOKING NOW AT THE POSSIBILITY OF A SQUALL LINE DEVELOPING AHEAD OF THE FRONT SATURDAY NIGHT FOLLOWED BY STORMS ASSOCIATED WITH THE FRONT ITSELF EARLY SUNDAY AFTERNOON. THE LOW DEEPENS TO THE 985ISH MB RANGE OVER THE GREAT LAKES ON SUNDAY AND TAKES ITS GOOD OLD TIME MOVING THROUGH ONTARIO AND QUEBEC THROUGH THE WEEK...IN FACT...IT APPEARS THAT IT GETS SHUNTED A LITTLE SOUTHEAST INTO NORTHERN MAINE BY WEDNESDAY. THE RESULT IS A COOL AND BREEZY WEEK AHEAD. WOULD NOT BE SURPRISED TO SEE A FEW IMPULSES ROTATING AROUND THIS LOW BRINGING A CHANCE OF A SHOWER BUT WILL NOT TRY TO TIME IT AT THIS POINT. A LATE MARCH WEATHER PATTERN FOR MID MAY. FCSTID = 25 .PBZ... MD...NONE. OH...FLOOD WARNING FOR THE MUSKINGUM RIVER IN COSHOCTON CO UNTIL 400 AM SATURDAY. PA...NONE. WV...NONE. TYBURSKI
