AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 137 PM EDT FRI APR 12 2002 SBCAPES TONIGHT ARENT TOO IMPRESSIVE...BUT STILL MAINTAIN 400+ IN AN AREA WHERE UPPER DIVERGENCE IS FAIRLY STRONG. LIS REMAIN NEGATIVE OVER FCST AREA THROUGH THE NIGHT. HAVE SEEN A FAIR CORRELATION THIS MORNING WITH ETAS 250MB DIVERGENCE AND WILL KEY ON THAT TONIGHT FOR A STRONGER MENTION OF THUNDERSTORMS. THIS PUTS FOCUS ON THE NORTHWEST QUARTER OF FCST AREA THROUGH 12Z JUST AHEAD OF S/W AND UNDER VORT THAT TRACKS THROUGH NRN IND. WILL BUMP THUNDER CHANCE TO LIKELY HERE WITH CATEGORICAL POPS. EXPECT TO STAY CLOSER TO WARMER FWC NUMBERS TONIGHT. FOR TOMORROW...MAJORITY OF FORCING GETS MOVED NORTHEAST OF FCST AREA BUT MOISTURE AND SOME INSTABILITY LAGS OVER CWA. AM HOPEFUL THAT PRECIP WONT LAST LONG THROUGH THE MORNING HOURS...ESPECIALLY NORTHWEST...BUT CANT RULE OUT SHOWERS AND WILL CONTINUE WITH CHANCE WORDING. DAYTIME HIGHS WILL BE SIGNIFICANTLY COOLER IN THE NORTHWEST AS READINGS BEHIND CDFNT TODAY ARE STRUGGLING TO GET THROUGH THE 50S. WILL BREAK HIGHS FROM LOW 60S NW TO LOW 70S SE. THOUGH THE FRONT MOVES THORUGHFCST AREA SATURDAY...SOME LINGERING SHOWERS BEHIND IT ARE POSSIBLE THROUGH THE NIGHT AND WILL WORD AS SCATTERED WITH A 30 POP EXCEPT FOR 40 IN THE SOUTHEAST. THIS RUNS INTO SUNDAY MORNING IN THE SOUTHEAST WHERE LOW CHANCE POPS ARE REASONABLE. FWC NUMBERS LOOK REASONABLE ON SUNDAY WITH PC SKIES. EARLY PART OF NEXT WEEK SHOULD BE DRY WITH BUILDING H5 RIDGE AHEAD OF DEEPING LOW IN THE PLAINS. GULF MOISTURE COMES BACK AND NEXT FRONT APPROACHING BY MID WEEK SHOULD WRING OUT SOME SCATTERED SHOWERS. SFC LOW PASSES N OF FCST AREA IN EXTENDED BUT DROPS A FRONTAL BOUNDARY FROM SW-NE WHICH IS EXPECTED TO BE A FOCUS FOR SHOWERS STARTING ON WEDNESDAY. HOWEVER...MRF IS THROWING A HUGE DIURNALLY INFLUENCED AREA OF QPF OVER THE SERN 1/3 OF THE U.S. THAT IS LIKELY OVERDONE. ID RATHER HOLD OFF MENTION OF PRECIP DURING THE DAY ON WEDNESDAY...BUT CURRENT FCST HAS IT IN AND THERE IS ALWAYS TIMING ISSUES THIS FAR OUT IN THE FCST. BEGINNING WEDNESDAY...WILL EXPECT MOCLOUDY SKIES WITH A CHANCE OF SHOWERS AND THUNDERSTORMS DUE TO THE BOUNDARY THAT SOWLY MOVES SOUTHEAST OF FCST AREA BY NEXT WEEKEND. .ILN...NONE FRANKS
