AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
725 PM EDT SUN JUN 21 2009

.AVIATION...DISCUSSION FOR 00Z TAF ISSUANCE.

WAA...DAYTIME HEATING AND A WEAK LOW LEVEL CONVERGENT AXIS HAS AGAIN
LEAD TO SCT -TSRA AND -SHRA ACROSS THE AREA. THE GREATEST
INSTABILITY REMAINS ACROSS IL OR SW OF THE TAF SITES SO IT WOULD
APPEAR THAT HUF IS THE ONLY SITE THAT MAY BE AT RISK FOR BEING
IMPACTED BY A TSRA THIS EVENING AND THAT RISK APPEARS LOW AT THIS
TIME.

ALL IN ALL LOOK FOR PREVAILING VFR CONDS TONIGHT WITH SOME LOW RISK
FOR MVFR VIS CONDS WITHIN THE LIGHT WINDS AND HIGH HUMIDITY
ENVIRONMENT HOWEVER LAST NIGHT NO VIS RESTRICTIONS DEVELOPED DUE MID
LVL CLOUDINESS HOWEVER IT APPEARS THAT THE BULK OF MID/HIGH LVL
CLOUDINESS MAY SHIFT NE OF THE CWA LATER TONIGHT SO WE WILL INCLUDE
A PERIOD OF MVFR LATER TONIGHT.

&&

.PREV DISCUSSION...A BROAD WEAK SFC HIGH PRES STRETCHED FROM THE
GULF STATES UP INTO THE GRT LKS AT MIDDAY. SATELLITE DEPICTED
SLIGHTLY MORE EXTENSIVE CLOUD COVER ALONG A SFC TROF FM CNTRL KY AND
INDIANA BACK TO NW IL. SCT SHRA WITH ISOLD THUNDER EMBEDDED IN THIS
BAND ESPECIALLY FM ILLINOIS BACK INTO SOUTH DAKOTA. GRTLKS PORTION
OF HIGH KEEPING DEWPOINTS TO LOWER AND MIDDLE 60S IN NORTH AND EC
INDIANA WHILE WEST AND SOUTH PARTS OF STATE DEWPOINTS RUN FROM UPPER
60S TO MID 70S.

MAIN CHALLENGE WL BE POPS NEXT 24 HOURS AND ASSOCD CLOUDS POTENTIAL
IMPACT ON TEMPS.

MODELS ARE IN PRETTY GOOD AGREEMENT OVERALL AND WL USE A BLEND. SLOW
CHANGE IN THE ONGOING WEATHER PATTERN AS DEEPER LAYERED MOISTURE WRN
INDIANA ON WEST WILL GRADUALLY OVERSPREAD CENTRAL INDIANA TONIGHT
AND MONDAY AS UPPER RIDGE AXIS OVER ILLINOIS FLATTENS SOME AND
SHIFTS OVR INDIANA WITH WEAK SHEAR AXIS. END RESULT IS FOR MORE
CLOUDINESS TONIGHT AND MONDAY. LIKE TODAY...SCT RW/TRW EMBEDDED IN
RH AXIS WILL SHFT TO INDIANA. SVR STORMS NOT EXPECTED GIVEN WEAK
SHEAR. WITH EXTRA CLOUDINESS AND HIGHER DEWPOINTS...MIN TEMPS
TONIGHT AT OR JUST ABOVE LAST NIGHT THOUGH MUNCIE AREA COULD SLIP
INTO MID 60S GIVEN LOW 60 DEWPOINTS.  MON MAX TEMPS ARE FCST TO BE
AS HIGHS AS TODAYS GIVEN SLIGHTLY HIGHER THICKNESS. THIS WILL BE
OFFSET SOME BY MORE CLOUDINESS AND SHOULD ANY LOCATION SEE SHOWERS
PERSIST...MAX TEMPS COULD STAY BIT LOWER THAN CURRENT FCST.

MON NGT...DEEP LAYERED RH AND SHEAR AXIS GRADUALLY PUSH EAST SO
CONTINUED EVENING CHC FOR STORMS AND KEPT LOWS UPPER 60S TO LOWER
70S.

TUE INTO WED...RIDGE CONTINUES TO BUILD IN LIMITING RAIN CHANCES BUT
KEEPING HUMIDITY RATHER HIGH.  TEMPS FEW DEGREES WARMER THAN MONDAY
WITH MIN UPPER 60S TO LOWER 70S AND HIGHS UPPER 80S TO LOWER 90S.

THU INTO FRI...GFS AND EURO FLATTEN UPPER RIDGE AS WEAK SHORT WAVE
RIDES ACROSS TOP...THUS BRINGING RETURN THREAT FOR STORMS AT THAT
TIME WHILE TEMPS AND HUMIDITY REMAIN MID SUMMER LIKE.

SAT INTO SUN...UPR RIDGE BUILDS BACK BRIEFLY AFTER PASSAGE OF WAVE
THUR INTO FRI BUT THIS IS SHORT-LIVED AS GFS AND EURO INDICATE
ANOTHER SHORT WAVE TO TOP RIDGE AND RENEW RAIN CHCS WHILE SFC BNDRY
MEANDERS BETWEEN GRTLKS AND OH VLY.
