AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
243 PM EDT SUN JUL 20 2008

.DISCUSSION...

FORECAST FOCUS IS ON CHANCES FOR RAIN THROUGH MID WEEK.

AT 18Z A SFC BOUNDARY EXTENDED ACRS NRN SECTIONS OF CENTRAL IN INTO
IL. SCT TSRA WERE FIRING ALONG THIS BOUNDARY AS WELL AS POPPING UP
ACRS REMAINDER OF FORECAST AREA /FA/ DUE TO UNSTABLE ATMS. TSRA WERE
ALSO TRYING TO GET GOING IN WRN IA.

MODELS ARE IN DECENT AGREEMENT. NO ONE MODEL IS DOING GREAT WITH
CONVECTION BUT THE MODELS MAIN MASS FIELDS ARE SIMILAR. WILL USE A
BLEND...BUT CONFIDENCE IS LOW DUE TO UNCERTAINTY OF MCS DEVELOPMENT
WHICH OFTEN ARE NOT HANDLED WELL BY MODELS.

EXPECT SCT TSRA TO CONTINUE INTO THIS EVENING WITH BOUNDARY IN THE
AREA AND CONTINUED UNSTABLE ATMS. WILL CONTINUE CHC POPS THIS
EVENING. MEANWHILE...STRONG WARM ADVECTION BEGINS ALOFT ACROSS NE/IA
WHICH SHOULD FIRE ANOTHER MCS. THIS MCS WILL TRACK TOWARD THE FA
OVERNIGHT. SOME QUESTION AS TO WHETHER IT WILL MAKE IT TO THE FA BY
12Z. THUS AM NOT CONFIDENT ENOUGH FOR LIKELY POPS OVERNIGHT. WENT
HIGH CHANCE POPS NW FA OVERNIGHT /CLOSEST TO POTENTIAL MCS TRACK/
WITH LOWEST POPS SE FA /FARTHEST AWAY FROM POTENTIAL MCS TRACK/.
THESE ARE STILL HIGHER THAN MOS WHICH ATTM DOES NOT LOOK LIKE IT
HANDLES THE SITUATION WELL. WITH CLOUDS AROUND AND A CONTINUED HUMID
AIRMASS...FEEL THAT MAV TEMPS ARE TOO COOL. BLENDED MAV WITH THE
WARMER MET VALUES.

ON MON REMNANTS OF MCS MAY BE MOVING ACROSS FA DURING THE
MORNING...WITH MORE SCT STORMS FIRING IN THE AFTN ALONG REMNANT
BOUNDARIES. WITH TIMING AND COVERAGE UNCERTAIN...KEPT CHANCE POPS
ALL DAY. MAV TEMPS LOOK TOO WARM GIVEN CLOUDS AND TSRA AROUND. WENT
CLOSER TO MET NUMBERS.

UPPER TROF WILL DIG SW INTO THE AREA MON NIGHT INTO TUE AND BRING
COOLER AND DRIER AIR INTO THE AREA BY WED. TSRA THREAT WILL CONTINUE
MON NIGHT AND TUE ACROSS ENTIRE FA AS ANOTHER MCS MAY RIDE ACROSS
SRN FA. BELIEVE ENUF DRIER AIR WILL WORK INTO NRN FA TO END RAIN
THREAT THERE BY TUE AFTN. ENDED RAIN REMAINDER OF FA BY TUE NIGHT.
GFS IS A BIT STRONGER WITH UPPER LOW AND KEEPS RAIN THREAT INTO
WED...BUT IT IS AN OUTLIER ATTM SO WILL CONTINUE DRY FORECAST WED.

NEXT WAVE WILL IMPACT FA THU NIGHT INTO FRI SO CONTINUED LOW CHC
POPS THEN. REMOVED POPS ON THU AS TIMING NOW APPEARS TO BE THU NIGHT.

.AVIATION...DISCUSSION FOR 18Z TAFS

SCATTERED SHOWERS AND A FEW THUNDERSTORMS WERE DEVELOPING NEAR A CD
FRONT FROM JUST SOUTH OF KCHI TO KMLI. A FEW OF THESE THUNDERSTORMS
MAY MOVE NEAR OR ACROSS THE KLAF AREA THIS AFTERNOON. ELSEWHERE
FORECAST IS MORE MUDDLED AS MODELS ARE FORECASTING A QUIET PATTERN
BUT WITH A VERY UNSTABLE AIRMASS AND A COLD FRONT DRIFTING SOUTH
ACROSS OUR AREA.

I CANNOT RULE OUT A THUNDERSTORM ANYWHERE...BUT UNTIL LATE TONIGHT
ANY THUNDERSTORMS WILL PROBABLY BE ISOLATED SO WILL LEAVE OUT OF
TAFS FOR NOW.  THERE IS GOOD LOW LEVEL CONVERGENCE ACROSS IOWA AND
AND ANOTHER THUNDERSTORM COMPLEX WILL LIKELY DEVELOP OVERNIGHT AND
MOVE OUR WAY BY EARLY MONDAY MORNING. THUS WILL INCREASE MENTION OF
THUNDERSTORMS DESPITE WHAT MODELS ARE FORECASTING BY MONDAY.
