Drought conditions were greatly diminished over much of central and southwest Indiana by the end of September, while conditions continued to improve in south central portions of the state. The wet weather pattern of August continued in much of Indiana during September. Monthly rainfall was normal to much above normal in central and southern Indiana and generally below normal in northern Indiana. Precipitation totals ranged from 4 to more than 12 inches in central and southern Indiana. There were two widespread rainfall events during September that covered much of central and southern Indiana. The remnants and moisture from Hurricane Isaac produced rainfall of 1 to more than 4 inches from the 1st through the 8th. The last rainfall event of the month was a result of a series of low pressure areas that moved along a stationary front located in central Indiana. These systems dumped 1 to more than 6 inches from the 25th through the 27th. Between these two widespread rainfall events, there were three lesser events. At the end of the month, stream flow was above seasonal levels in much of central and southern Indiana.

.UPDATE...
THE AVIATION SECTION HAS BEEN UPDATED BELOW.

.SYNOPSIS...
ISSUED AT 320 PM EDT FRI AUG 31 2012
THE REMNANTS OF HURRICANE ISAAC CURRENTLY OVER SOUTHWEST MISSOURI
WILL DRIFT NORTH TO CENTRAL MISSOURI SATURDAY AND THEN MOVE EAST
ACROSS OUR REGION LATE SUNDAY AND MONDAY. WEAK HIGH PRESSURE WILL
DOMINATE OUR WEATHER AFTER ISAAC MOVES ON TO THE EAST. THEN A COLD
FRONT WILL MOVE ACROSS OUR REGION AROUND THE MIDDLE OF NEXT WEEK
AS AN UPPER TROUGH DIGS INTO THE UPPER MIDWEST.
&&
.NEAR TERM /REST OF TONIGHT/...
ISSUED AT 846 PM EDT FRI AUG 31 2012
RADAR MOSAIC SHOWS A FEW CONVECTIVE SHOWERS OVER SOUTHERN INDIANA
WITH THE BULK OF RAINFALL CURRENTLY OVER ILLINOIS. THESES SHOWERS
ARE EDGING EASTWARD BUT EVER SO SLOWLY AND THUS LOWERED POPS
THROUGH 2 AM. THE RAPID REFRESH SHOWS SOME ECHOES DEVELOPING
ACROSS THE NORTHWEST AND SOME MOVING INTO THE SOUTHWESTERN
COUNTIES LATER TONIGHT AND THUS MAINTAINED SOME LIKELY POPS IN THE
WEST BUT CUT CHANCES LOWER ELSEWHERE FOR THE OVERNIGHT. LOADED
NEWEST HPC QPF AND THIS STILL LOOKS LIKE UP TO HALF AN INCH IN THE
WEST WITH MUCH SMALLER AMOUNTS IN THE NORTH AND EAST. CONTINUED
TO KEEP ONLY ISOLATED THUNDER IN THE SOUTH UNTIL 2 AM AND THEN
INCLUDE IT EVERYWHERE. GOING LOWS IN THE LOWER 70S STILL LOOK ON
TRACK.
&&
.SHORT TERM /SATURDAY THROUGH MONDAY/...
ISSUED AT 320 PM EDT FRI AUG 31 2012
MODELS AND HPC HAVE TRENDED A LITTLE SLOWER WITH MOVING THE REMAINS
OF ISAAC EAST ACROSS OUR REGION. AS A RESULT RAIN AMOUNTS WILL BE A
BIT LESS THAN PREVIOUSLY FORECASTED AND THE HEAVIEST AMOUNTS WILL
BE ACROSS OUR WEST. ALSO WITH THE SLOWER MOVEMENT...WILL MENTION
HEAVY RAIN IN SOME AREAS LASTING INTO SUNDAY NIGHT. CURRENT HPC
HAS CENTER OF ISAAC JUST WEST OF SAINT LOUIS SATURDAY... OVER
CENTRAL ILLINOIS SUNDAY AND MOVING ACROSS OUR REGION MONDAY.
HEAVIEST RAINFALL WILL BE OCCURRING ON THE EAST SIDE OF THIS
SYSTEM.
MAXIMUM PRECIP TOTALS FROM TONIGHT THROUGH SUNDAY NIGHT WILL RANGE
FROM NEAR 3 INCHES OVER FAR EASTERN SECTIONS TO ABOUT 5 INCHES FAR
WEST. THIS IS OVER A 48-60 HOUR PERIOD AND 24 HOUR FLASH FLOOD
GUIDANCE IS RUNNING AT LEAST 5 INCHES. BASED ON THE HIGH AMOUNTS
NEEDED FOR FLOODING AND THAT THIS WILL BE A PROLONGED HEAVY RAIN
EVENT...I THINK THERE WILL BE ONLY A MINIMAL FLOOD CONCERN
SATURDAY. HOWEVER THE THREAT OF FLOODING WILL BE MUCH HIGHER SUNDAY
AND SUNDAY NIGHT AS PERIODS OF HEAVY RAIN CONTINUE. LOW LAND
FLOODING ALONG CREEKS AND STREAMS WILL BE THE MAIN ISSUE. HOWEVER
LOCALIZED HIGHER AMOUNTS ARE POSSIBLE AND AREAS THAT RECEIVE MORE
RAIN COULD RECEIVE MUCH WORSE FLOODING.
BASED ON THE SLOWER MOVEMENT WILL LOWER RAIN AMOUNTS A LITTLE
SATURDAY...ESPECIALLY EAST AND RAISE AMOUNTS SLIGHTLY SUNDAY NIGHT
AND MONDAY.
AS FAR AS TEMPERATURES ARE CONCERNED...LOWS WILL BE IN THE LOWER 70S
AND HIGHS IN THE UPPER 70S TO LOWER 80S BOTH DAYS. WARMEST
TEMPERATURES SATURDAY WILL BE IN THE EAST AS SHOWERS WILL BE LESS
NUMEROUS THERE.
&&
.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
ISSUED AT 320 PM EDT FRI AUG 31 2012
MODELS STILL DISAGREE ON TIMING OF AN UPPER TROUGH AND ASSOCIATED
FRONT MID WEEK. WITH NO CLEAR FAVORITE HERE...DECIDED TO STICK WITH
ALLBLEND FOR INITIALIZATION. ALLBLEND INITIALIZATION LOOKS GOOD WITH
MOST OTHER FEATURES AS WELL.
KEPT AT LEAST SLIGHT CHANCE POPS MONDAY NIGHT INTO TUESDAY SINCE
EJECTION OF ISAAC REMNANTS CONTINUE TO SLOW WITH EACH MODEL RUN.
TUESDAY NIGHT SHOULD BE DRY...BUT INTRODUCED POPS WEDNESDAY AND
WEDNESDAY NIGHT DUE TO THE UNCERTAINTY IN THE MID WEEK FRONTAL
SYSTEM. SIMILAR POPS CONTINUE FOR THURSDAY WITH FRONT STILL IN THE
AREA. WITH THE UNCERTAINTY...KEPT POPS IN SLIGHT CHANCE TO LOW
CHANCE CATEGORY.
THURSDAY NIGHT AND FRIDAY THEN LOOK DRY WITH HIGH PRESSURE BUILDING
IN.
TEMPERATURES LOOK SEASONABLE FOR THE MOST PART...BUT COOL TO BELOW
AVERAGE BEHIND COLD FRONT FOR THE END OF THE WEEK.

ISSUED AT 1230 AM EDT SAT SEP 1 2012
CONDITIONS GRADUALLY DETERIORATING FROM THE WEST AS REMNANTS OF
HURRICANE ISAAC PUSH EASTWARD. BY LATE MORNING WIDESPREAD MVFR
CEILINGS AND LOCAL MVFR VISIBILITIES IN SHOWERS. BY LATE AFTERNOON
WIDESPREAD IFR CEILINGS AND MVFR VISIBILITIES IN HEAVY SHOWERS. SOME
