AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 210 PM EDT SUN AUG 27 2006 .FCST DISCUSSION...LATEST SFC MAP SHOWS A WEAK LOW ACROSS NE OHIO WITH A COLD FRONT EXTENDING ACROSS CENTRAL INDIANA INTO MISSOURI. TSRA ARE DEVELOPING AHEAD OF THIS FRONT SOUTH OF I-70. PRECIPITABLE H2O VALUES OF 1.75 TO 2 INCHES REMAIN ACROSS THE REGION. MAIN UPPER WAVE IS STILL LAGGING BACK ACROSS THE CENTRAL PLAINS. LATEST PROFILER NETWORK SHOWS 5-15KT WESTERLY 850MB WINDS. OVERALL MODEL FEATURES SHOWING MINOR DIFFERENCES IN THE PLACEMENT AND TIMING OF PRECIP TONIGHT/MONDAY. NGM IS THE ONLY MODEL THAT FOCUSES BULK OF PRECIP SOUTH OF THE REGION. BASED UPON THE POSITION OF THE 850-600MB FRONTOGENESIS LOCATION TONIGHT-MON I WILL FOLLOW THE MORE NORTHERLY ETA/GFS PRECIP FCST WHILE ACKNOWLEDGING THE SPURIOUS GFS QPF BULLSEYE. MAIN FORECAST ISSUE WL BE EXTENT OF RAIN OVR NEXT 24-36 HOURS. THIS EVENING AND OVERNIGHT...EXPECT AN INCREASE IN PRECIP WITH DIURNAL HEATING ACROSS THE SOUTHERN HALF OF THE CWA. WET MICROBURSTS WOULD BE THE MAIN THREAT WITH ANY STORMS SINCE 6KM WIND SHEAR REMAINS LESS THAN 30KTS. I HAVE THE HIGHEST PRECIP CHCS ACROSS THE SOUTH THIS EVENING. BY LATER TONIGHT...850MB WINDS WILL TURN SSW WITH OVERRUNNING/ISENTROPIC LIFT OVER THE 850MB FRONT. 850-600MB FRONTOGENESIS ALSO INCREASES AFTER MIDNIGHT MAINLY ACROSS THE NW HALF OF THE STATE INTO THE NORTHERN HALF OF IL. IN A NUTSHELL, I WILL KEEP LIKELY AT ALL LOCATIONS AFTER MIDNIGHT WITH LOCALLY HEAVY RAINS POSSIBLE. MONDAY...ETA/GFS AND NGM ALL SHOW THE BULK OF LIFT MOVING ACROSS THE AREA. THIS SHOULD LEAD TO OCCASIONAL TSRA WITH MORE HEAVY RAINS POSSIBLE. I HAVE RAISED PRECIP CHCS TO MIRROR MOS AVGS WHICH ARE IN THE LIKELY/CATEGORICAL RANGE. GIVEN THIS, I WILL KEEP FCST HIGHS ON THE COOL SIDE OF GUIDANCE MOS. BASED UPON THE BLOCKY NATURE OF THE HEMISPHERIC FLOW PER HPC DISCUSSION I WILL OPT FOR THE SLOWER ETA SOLUTION OF LINGERING PRECIP CHCS INTO TUES. THE UPPER LOW SHOULD WEAKEN AS IT MOVES ACROSS THE REGION TUES-WEDS AS IT INTERACTS WITH THE TROPICAL SYSTEM. HOWEVER, IT APPEARS THAT THE SFC FRONT AND 850MB FRONT SHOULD BE SE OF THE REGION BY TUES NIGHT. THE ETA DOES DRAG A DEFORMATION ZONE ACROSS THE AREA TUES AND I WILL CONTINUE THE GENERAL 40 POPS. NO CHANGES WILL BE MADE TO THE EXTENDED WITH A HIGH AMPLITUDE/BLOCKY LONGWAVE PATTERN TO PERSIST. DRY WX WITH NEAR SEASONAL TEMPS APPEAR IN STORE LATER THIS WEEK. && AVIATION...DISCUSSION FOR 271800Z TAF ISSUANCE. A STATIONARY FRONT IS STALLED ACROSS CENTRAL INDIANA THROUGH THE FORECAST PERIOD. VERY MOIST AND UNSTABLE AIR WAS OVERRUNNING THE FRONT. VFR CONDITIONS WILL OCCUR OUTSIDE OF THE SCATTERED THUNDERSTORMS. MORE UNSTABLE AIR WILL MOVE UP FROM THE SOUTHWEST INCREASING THE COVERAGE OF THUNDERSTORMS LATER IN THE AFTERNOON. OVERNIGHT THE FRONT WILL MOVE SLIGHTLY TO THE SOUTH. WITH MOISTURE CONTINUING TO INCREASE OVER THE AREA THE RAIN COVERAGE WILL INCREASE. CONDITIONS WILL DECREASE TO MVFR IN THE RAIN AND FOG. CONDITIONS WILL REMAIN LOW THROUGH THE MORNING. .IND WATCHES/WARNINGS/ADVISORIES...NONE. && AVIATION...HAINES PUBLIC...CO
