NWS Wilmington, OH wrote its last area forecast discussion before the first event at Aug 30, 2:45 AM EST, 1 hour earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 345 AM EDT SAT AUG 30 2003 LATEST MODEL DATA SUGGESTS THAT PRECIPITATION WILL PUSH SOUTH OF THE FORECAST AREA THIS MORNING AS THE FRONT BECOMES QUASI-STATIONARY JUST TO THE SOUTH OF THE AREA. QUESTION IS HOW LONG OF A LULL THERE WILL BE IN RAINFALL. ETA HAS BECOME DRY AGAIN WHILE THE GFS REMAINS RATHER WET. THE SPREAD IN SOLUTIONS MEANS THAT CONFIDENCE IS LOW. WILL GO WITH SOMETHING OF A COMPROMISE. EXPECT MOST OF THE AREA TO BE RAIN FREE FROM LATER TODAY INTO SUNDAY MORNING ALTHOUGH WILL PROBABLY KEEP A LOW CHANCE GOING IN SOUTHERN ZONES. THEN EXPECT CHANCE TO START TO INCREASE AGAIN SUNDAY AFTERNOON SIMILAR TO NESTED GRID MODEL. WILL KEEP FAIRLY HIGH PROBABILITIES FOR SUNDAY NIGHT THROUGH MONDAY NIGHT AS IT APPEARS THAT FRONTAL ZONE MAY BECOME MORE ACTIVE AS SHORT WAVE ENERGY MOVES OUT OF THE CENTRAL PLAINS. FOR TEMPERATURES DECIDED TO STAY WITHIN A FEW DEGREES OF NGM MOS. ITS PARENT MODEL LOOKED MOST REALISTIC OVERALL AND THOSE TEMPERATURES WERE CLOSE TO THE PREVIOUS FORECAST. .ILN...NONE.
