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.
