AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PITTSBURGH PA 1035 AM EDT SAT AUG 30 2003 MIDNIGHT SHIFT DID A SPLENDID JOB IDENTIFYING FLOODING POTENTIAL WITH THEIR WATCH PLACEMENT. NUMEROUS REPORTS OF 1.5 TO 2.5 OF RAIN OVER THE CENTRAL PORTION OF THE CWA. CURRENTLY...THREE WARNINGS STILL ACTIVE IN OHIO FOR CONTINUED FLOODING REPORTED BY EMA. SINCE RAIN HAS ENDED OVER THIS AREA LITTLE MORE IN THE WAY OF RUNOFF IS EXPECTED...SO WILL LET THOSE WARNINGS EXPIRE SHORTLY. WILL LET THE FLOOD WATCH CONTINUE AS THERE ARE STILL A FEW SLUGS OF RAIN AND MORE CONCENTRATED ACTIVITY IN NORTHERN WEST VIRGINIA NEAR THE FRONT. DIFFERENCES IN THE SHORT TERM MODELS AS THE ETA DRIVES THE FRONT WELL INTO WEST VIRGINIA THEN MOVES MOISTURE BACK TO THE NORTH LATE MONDAY. CONVERSELY...THE GFS STALLS THE FRONT JUST TO OUR SOUTH GIVING US JUST A LITTLE BIT OF CLEARING...ESPECIALLY NORTH...BEFORE THE MOISTURE RETURNS ON SUNDAY. SO BOTH MODELS BRING THE FRONT BACK TO THE NORTH...THEY JUST DO SO AT DIFFERENT TIMES. CONSENSUS AMONG SURROUNDING OFFICES AND HPC IS TO FOLLOW THE 06Z/GFS. LOOKING AT CURRENT RADAR AND SATELLITE SHOWS A WAVE MOVING INTO SOUTHWESTERN OHIO WHICH SHOULD HELP SLOW THE SOUTHWARD PROGRESSION OF THE FRONT WHICH SUPPORTS THE GFS SOLUTION. THE FRONT SHOULD REMAIN OVER THE REGION UNTIL AT LEAST WEDNESDAY WHICH WILL BRING PLENTY OF RAINFALL TO USHER IN METEOROLOGICAL AUTUMN. LOOKING FORWARD TO PLENTY OF COLOR ON THE TREES THIS FALL WITH ALL THE RAIN WE HAVE SEEN THIS SEASON.
