AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 316 PM EDT SAT JUL 10 2004 .SHORT TERM (TONIGHT THROUGH MONDAY NIGHT)... KILN RADAR INDICATED SHOWERS AND THUNDERSTORMS DEVELOPING MAINLY ALONG AND SOUTH OF A WEAK BOUNDARY LOCATED EAST-WEST THROUGH CENTRAL OHIO AND CENTRAL INDIANA THIS AFTERNOON. EXPECT THIS ACTIVITY TO DIMINISH SOME WITH THE LOSS OF DAYTIME HEATING BUT THREAT WILL REMAIN ALL NIGHT. WILL START WITH LIKELY POPS...MAINLY CENTRAL AND SOUTH...AND DECREASE TO CHANCE OF PRECIPITATION OVERNIGHT. GFS AGAIN EXHIBITING CONVECTIVE FEEDBACK PROBLEMS AND PREFER TO TREND TO ETA SOLUTION. WEAK SHORT WAVE MOVES THROUGH TONIGHT AND AGAIN ON MONDAY WHEN WE GET INTO NW FLOW. KEPT POPS IN CHANCE CATEGORY THROUGH OUT SHORT TERM. CONTINUED CLOSE TO CURRENT FORECAST TEMPERATURES AND A BLEND OF ETA AND GFS. && .LONG TERM (TUESDAY THROUGH FRIDAY)... UPPER LOW BUILDS DOWN INTO THE GREAT LAKES AND OHIO VALLEY THROUGH THE END OF THE WEEK. WILL KEEP MENTION OF RW/TRW UNTIL AXIS OF TROF PASSES WHICH IS ON WED INTO WED NIGHT. COOLER LESS MUGGY CONDITIONS CAN THEN BE EXPECTED FOR THE END OF THE WEEK AS NWLY FLOW ALOFT CONTINUES. A SECONDARY TROF APPROACHES FOR THE LATTER HALF OF THE WEEKEND BRINGING A SOME RETURN FLOW OUT OF THE SOUTH (I.E. WARMER AND MUGGIER CONDITIONS). && .AVIATION (18Z-18Z)... H5 S/W RUNNING INTO MEAN RIDGING WILL FLATTEN OUT AND LEAVE AN ENHANCED AREA OF VORTICITY OVER OHVLY THIS AFTERNOON AND TONIGHT... BEFORE SLOWLY DYING OUT AND MOVING ESE ON SUN. SFC BOUNDARY IN SRN FCST AREA PER MSLP FIELD IS PROBABLY FURTHER N WHERE LOWER DEWPOINTS IN THE UPPER 60S ARE NOTED...FROM NE OH THROUGH NRN IL. REST OF AMS IS QUITE JUICY WITH LOW TO MID 70S DWPTS AND WEAK WIND FIELDS. PROBLEM WITH TAFS IS THAT POPUP THUNDERSTORMS WILL BE AROUND THIS AFTERNOON AND LIKELY TRANSITION TO MORE SHOWERY PRECIP TONIGHT WITH JUST ISOLD THUNDER. THIS STILL LEAVES 4 HOUR GROUPINGS IN THE TAFS BECAUSE OF TEMPO RULE. THINKING IS THAT THERE WILL BE ABOUT 30% COVERAGE EARLY THIS AFTERNOON AND THEN HAVE AN HOUR OR THREE THIS EVENING OF PREVAILING THUNDERSTORMS AT ANY TAF SITE. NO MAJOR DISTINCTIONS BETWEEN TAFS AS THEY ARE ALL UNDER THE SAME AIRMASS AND EQUALLY SHARE THE CHANCE OF POPUP STUFF THIS AFTERNOON...AND SHOWERY ACTIVITY TONIGHT AND TOMORROW. && .ILN WATCHES/WARNINGS/ADVISORIES... IN...NONE. KY...NONE. OH...NONE. &&
