Area forecast discussion, Jun 4, 2:11 PM EDT, 4 hours 18 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 211 PM EDT TUE JUN 4 2002 SCT TSRA SPARKING OVER FCST AREA AND WILL INCLUDE THIS TONIGHT RANGING FROM 50 POPS NW TO 30 POPS SE. MAIN THREAT WILL BE HAILERS SINCE WIND FIELDS ARENT THAT IMPRESSIVE. HAVE BUMPED POPS BY WEDNESDAY EVENING TO CATEGORICAL WITH OCCASIONAL WORDING. HAVE ONLY TOUCHED UP TEMPS FOR THE NEXT FEW DAYS AND WENT SLIGHTLY COOLER THAN GUIDANCE ON WED INTO THURS SINCE COLD AIR BEHIND FRONT SEEMS TO BE UNDERDONE BY MODELS. AFTER FROPA LATE WEDNESDAY...HIGH PRESSURE AT THE SURFACE BUILDS IN AND A BROAD H5 RIDGE REMAINS OVER ERN U.S. AM CONCERNED THAT THERE WILL BE A GOOD AMOUNT OF CU ON BACK SIDE OF FRONT. STILL SOME MOISTURE CONVERGENCE HERE AND DOWNWARD MOTION ISNT THAT IMPRESSIVE TO KILL CU DEVELOPMENT. WILL CHANGE MOSTLY SUNNY TO PARTLY CLOUDY HERE...AND TEMPS STILL LOOK REASONABLE IN THE LOWER 70S. WILL CONTINUE WITH PREVIOUS FCST AND JUST INCREASE DAYTIME TEMPS 2-3 DEGREES EACH DAY WITH A GRADUAL MODIFICATION OF THE AIRMASS. MOISTURE SHOULD BEGIN TO STREAM BACK IN FROM THE GULF...BUT DO NOT THINK THAT THE MRF SOLUTION OF THE DIGGING H5 TROF IN THE WRN GULF STATES IS REASONABLE. ECMWF...UKMET...AND CANADIAN ALL SUGGEST A WEAK RIDGE WHICH CUTS THAT WIDE PATH OF PRECIP NOTED ON MRF. SINCE THE GULF DOES BEGIN TO OPEN IN THE LOWER LEVELS...WILL CONTINUE A CHANCE OF LATE DAY THUNDERSTORMS ON MONDAY AND TUESDAY. MISILN OUT AROUND 3 PM. .ILN...NONE. FRANKS
