NATIONAL WEATHER SERVICE INDIANAPOLIS IN
130 PM EDT WED AUG 29 2007

.AVIATION...DISCUSSION FOR THE 18Z TAFS

A COLD FRONT WILL BE MOVING THROUGH CENTRAL INDIANA LATER THIS
AFTERNOON AND EVENING. THERE IS LIMITED MOISTURE AND INSTABILITY
WITH THE FRONT SO ONLY ISOLATED THUNDERSTORMS WILL OCCUR WITH IT.
ALL STATIONS WILL BEGIN THE 18Z TAF PERIOD VFR. AN AREA OF LOW LEVEL
MOISTURE WILL MOVE INTO THE TAF LOCATIONS 06Z-08Z. THIS WILL CAUSE
MVFR CONDITIONS. AFTER 12Z MUCH DRIER AIR WILL BEGIN TO MOVE INTO
THE AREA. CONDITIONS WILL BEGIN TO IMPROVE TO VFR AFTER 12Z THEN
GOING COMPLETELY VFR BY 14Z.

&&

.DISCUSSION...

PROBLEM OF DAY IS WHETHER RAIN TONIGHT FROM FRONT TO NORTH.

NEITHER Q-VECTORS NOR FRONTOGENESIS FROM ANY OF THE MODELS INDICATE
MUCH SUPPORT. PASSAGE WILL PROBABLY BE WELL PAST PEAK CONVECTION
TIME. ON THE PLUS SIDE...TEMPERATURE GRADIENT INDICATES FRONT IS
FAIRLY STRONG RIGHT NOW...AND AT LEAST THE NAM HAS PRETTY STRONG
INSTABILITY ASSOCIATED WITH IT OVERNIGHT.

GUIDANCE POPS ARE ON ORDER OF 15-20 PERCENT. WITH THE INSTABILITY
THAT IS PROGGED...I WILL GO MORE WITH 25-30 PERCENT TONIGHT. WHILE
THE LIKLIEHOOD IS NOT THAT STRONG...DO WANT CHC CATEGORY.

BEGINNING TOMORROW DRY FOR SEVERAL DAYS AS ALL MODELS BUILD HIGH
BELOW AND RIDGE ALOFT.

GUIDANCE TEMPS CLOSE TONIGHT AND AGREE WELL WITH EXTRAPOLATION. FOR
THURSDAY TO SATURDAY MET SEEMS TO BE OUTLIER ESPECIALLY DURING DAY
AND WONT USE. MY PERSONAL ESTIMATES BASED ON UPSTREAM AND 850 PROGS
ARE FOR A CONSENSUS BETWEEN MAV AND FWC...AND THAT IS WHAT I WILL GO
WITH.
