AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 1230 PM EDT SAT OCT 10 2009 .AVIATION...DISCUSSION FOR 101800Z TAF ISSUANCE. DIURNAL CLDS BASED ARND 035 XPCTD TO DISSIPATE BY 110000Z WITH LOSS OF HEATING. MAJORITY OF THE DIURNAL DVLPMT XPCTD OVER THE ERN TERMINALS... KIND/KBMG.

WL HANDLE THIS WITH A SCT LYR IN THE FORECASTS FOR NOW. NO SIG WND/VSBYS ISSUES XPCTD THRU 110600Z. && .DISCUSSION... MAIN CHALLENGE FOR THE FCST WL BE CLOUD COVER...SFC WINDS AND RESULTANT FROST POTENTIAL AS WELL AS FREEZE POTENTIAL FOR THE NRN TIER TNGT AS WELL AS WHEN THE NEXT CHC OF PRECIP WL BE. 11-3.9 MICRON SATELLITE LOOP WAS SHOWING CLEARING JUST ABOUT TO OUR FAR NWRN COUNTIES WITH MORE THICK CLOUDS SPREADING E BEHIND A REINFORCING CD FNT FM ERN MN TO SRN CO. SFC ANLYS WAS ALSO SHOWING COLD WRN CANADIAN HIGH PRES FILTERING IN TO THE MSP AND OH VLYS. FINALLY...UA PATTERN FEATURED AN UPR LOW ACRS SRN MANITOBA WITH ZONAL FLOW ACRS THE OHIO VLY WITH AN ALASKAN SOURCE. MODELS WERE IN DECENT AGREEMENT WITH THE OVERALL EVOLUTION OF THE SYNOPTIC PATTERN THE NEXT FEW DAYS AND THUS BELIEVE COMPROMISE IS A GOOD START. MODELS IN FAIR AGREEMENT ON SWEEPING THE REFINFORCING FNT ACRS CNTRL INDIANA THIS AFTERNOON. BASED ON MODEL TIME SECS AND LYRD RH PROGS...ONLY EXPECT SOME INCRS IN MID AND UPR LVL CLOUDS TODAY AND TNGT BEHIND THE FNT. THESE CLOUDS SHOULD KEEP TEMPS FM GETTING QUITE AS COLD AS THE COLDER NAM MOS...HOWEVER THE NRN THIRD SHOULD LIKELY GET JUST BLW FREEZING. WITH THE CLOUDS AND WINDS EXPECTING TO STAY UP AROUND 5 KTS...CONFIDENCE NOT HIGH ENOUGH FOR A WARNING...BUT HIGH ENOUGH FOR A WATCH. WITH THE SAME LOGIC...DONT THINK FROST WL BE WIDESPREAD...BUT EXPECT AT LEAST PATCHY FROST. ON SUNDAY...UPR FLOW BECOMES MORE SW BUT STILL FAST AND SHOULD SEE IMPULSES BRING SOME INCRS IN HIGH CLOUDS HINTED AT BY MODEL TIME SECS. MODEL 850 MB TEMPS INCRS FM 1 TO 4 DEGREES CELSIUS THIS AFTERNOON TO AND SUNDAY AFTERNOON TO 6 TO 9 DEGREES ON MONDAY AFTERNOON WHICH SHOULD ALLOW FOR A LITTLE WARM UP AS ANOTHER FNT APPROACHES. THIS FNT EXPECTED TO MOVE THROUGH MONDAY NGT BUT BULK OF THE MOISTURE AGAIN TO OUR N...SO WL CONTINUE TO LEAVE IT OUT. NEXT CHC OF RN LOOKS LIKE THU FM A SRN SYS. AGAIN...LOOKS LIKE POTENTIAL FOR A LOT OF OVERRUNNING PRECIP ESP S OF THE OH RVR. MOS NUMBERS VERY CLOSE TODAY AND LOOK REASONABLE WITH CLEARING BUT COLD 850 MB TEMPERATURES FROM 1 TO 4 DEGREES CELSIUS. TNGT...WL GO WITH A COMPROMISE BETWEEN THE COLDER NAM AND WARMER GFS AS COLD AIR FILTERS IN BEHIND THE REINFORCING FNT BUT ALSO A FEW CLOUDS MAY BE AROUND. FINALLY...SUNDAY AGAIN LOOKS LIKE A COMPROMISE AS THE COLD AIR REMAINS ENTRENCED ACRS THE OH VLY. && .IND WATCHES/WARNINGS/ADVISORIES...FREEZE WATCH 08Z-12Z TNGT FOR NRN THIRD OF CNTRL IN. && PUBLIC...MK AVIATION...JAS
