AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
222 PM EDT THU JUN 11 2009

.DISCUSSION...LOW PRES WAS FOUND NEAR STL EARLY THIS AFTERNOON ALONG
WITH A WARM FRONT THAT EXTENDED EAST ACRS SRN IL AND CENTRAL IN.
MOIST DEW POINTS IN THE MIDDLE 60S WERE FOUND ACRS THE AREA. S/W WAS
VISIBLE NE OF IL...AND VIS PICTURES SHOW SOME BREAKS IN THE CLOUDS
ACRS IL AND WRN INDIANA.

MAIN FORECAST CHALLENGE TDY WL BE POPS.

WITH THE WELL DEFINED S/W TO OUR WEST...AND AS IT EXPECTED TO PUSH
ACRS CENTRAL INDIANA THIS AFTERNOON AND EARLY THIS EVENING...WL
CONTINUE AT LEAST CHC POPS ACRS THE AREA GIVEN OUR MOIST LOWER LVLS
AND FORCING ALOFT. NAM SEEMS TO HANDLE THIS FEATURE A BIT BETTER
THAN THE GFS AS IT APPEARS A BIT BETTER DEFINED. FURTHER SUPPORT
INCLUDES MAX HEATING AND INSTABILITY TO OCCUR THIS AFTERNOON WITH
CAPES NEAR 1000 J/KG AND LI/S NEAR -3. THUS WL RAISE POPS TONIGHT BY
10-20 PERCENT...BUT WITH FORCING EXPECTED TO DEPART BY 04Z-06Z WL
END PCPN CHCS BY THEN. AS FOR TEMPS...WITH PLENTY OF CLOUD LINGERING
AROUND AND MID 60 DEWPOINTS WL LEAN 1-2 DEGREES WARMER ON OVERNIGHT
LOWS THAN THE MAVMOS.

ON FRIDAY...A DIFFUSE UPPER PATTERN BEGINS TO TAKE SHAPE ACRS THE
AREA AS A WEAK AREA OF HIGH PRES BUILDS ACRS THE GRT LKS. CONVECTIVE
TEMPS ON FRIDAY ARE IN THE VERY REACHABLE LOWER 70S WITH LIMITED
CAPE AVAILABLE. ATTM CANNOT RULE OUT A STRAY SHRA OR TSRA ON FRI
AFTERNOON...BUT MOST AREAS SHUD REMAIN DRY. THUS WL GO FOR A SLIGHT
CHC POP ON FRIDAY AFTERNOON. MAVMOS HIGH TEMPS APPEAR VERY
REASONABLE AND WL STICK CLOSE.

GFS AND NAM AGREE THAT A POORLY DEFINED S/W WL PUSH TOWARD INDIANA
LATE FRIDAY NIGHT INTO SATURDAY. WL INTRODUCE A LOW CHC
POP...PARTICULARLY ACRS THE WRN PARTS OF THE FA. WITH A RELATIVELY
WARM AIR MASS STILL IN PLACE ACRS INDIANA...WL CONTINUE WITH CHC
POPS INTO SATURDAY. AGAIN WITH PLENTY OF CLOUDS AROUND ON FRIDAY
NIGHT INTO SATURDAY WL LEAN COOLER ON HIGHS AND WARMER ON LOWS THAN
MAVMOS.

GFS/NAM SUGGEST DRIER AIR ARRIVING ACRS CENTRAL INDIANA WITH GOOD
MIDDLE LEVEL SUBSIDENCE. THUS SUNDAY LOOKS LIKE A DRY DAY WITH
SLIGHTLY COOLER TEMPERATURES.

AS FOR THE EXTENDED...HIGH PRES EXPECTED TO SETTLE ARCS THE GRT LKS
AND PROVIDE A DRY EASTERLY SFC FLOW ACRS INDIANA. HOWEVER MUCH
WARMER AND MORE MOIST AIR WL BE FOUND JUST TO THE SOUTH OF INDIANA
OVR THE TN AND MISSISSIPPI RVR VALLEYS. THIS COULD LEAD TO AN
OVERRUNNING TYPE SITUATION. HOWEVER CONFIDENCE REMAINS LOW AS UPPER
SUPPORT APPEARS WEAK AND INCONSISTENT.  BY WED AND THURSDAY...AN
UPPER RIDGE WL BUILD ACRS THE RGN AND HELP TO PUSH THE LINGERING
FRONTAL BOUNDARY TO THE SOUTH ACRS INDIANA ON TUESDAY NIGHT AND INTO
WEDNESDAY. ATTM THIS APPEARS TO BE THE BEST SHOT FOR PCPN. EXPECT
WARMER TEMPS ON WED AND THURSDAY AS SFC FLOW BECOMES MORE SOUTHERLY
BEHIND THE WARM FRONT AND UNDER THE RIDGE.

.AVIATION...DISCUSSION FOR 18Z TAFS

VORT MAX CURRENTLY PUSHING EWD ACRS ERN MO INTO SWRN IL. LWR CLDS HV
SCTD OUT AHEAD OF THIS FEATURE ACRS SRN IL/SWRN IND WHERE MODERATE
DESTABILIZATION IS OCCURRING. THIS MORNING/S UA SUGGEST CONVECTIVE
TEMPS IN THIS AREA WL PROBABLY BE REACHED IN THE NEXT COUPLE OF
HRS...SO XPCTG SOME CONVECTIVE ACTVTY TO DVLP AHEAD OF VORT MAX.
MODELS INDICATE VORT MAX SHOULD BE E OF THE TAF SITES BY
112300Z...SO CONVECTIVE THREAT SHOULD REMAIN RATHER HIGH TIL
THEN...ESPECIALLY ACRS THE SRN TERMINALS. DIFFUSE FNT WL PROBABLY
SHARPEN UP A BIT AND BEGIN TO SHFT SEWD AS VORT MAX PASSES...WHICH
MAY ENHANCE CONVECTIVE CHCS AS WELL.

CIGS MAINLY ARND 030 XPCTD THIS AFT...WITH A TENDENCY FOR CIGS TO
LWR SOME IN THE WAKE OF FNT THIS EVEN. HIGH MOISTURE CONTENT IN THE
LWR LVLS COMBINED WITH THE SHALLOWNESS OF FNT MAY ALLOW FOR SOME IFR
CIGS TO DVLP TOWARDS 120600Z.
