AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
115 AM EDT WED AUG 3 2011

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

&&

.SYNOPSIS...LOW PRESSURE SLIDING SOUTHEAST FROM CANADA INTO THE
GREAT LAKES WILL PULL A COLD FRONT THROUGH CENTRAL INDIANA OVERNIGHT
AND INTO TOMORROW. THIS WILL BRING CHANCES FOR THUNDERSTORMS WITH
IT. AFTER THE COLD FRONTAL PASSAGE HIGH PRESSURE WILL BUILD BACK IN
AND TEMPERATURES WILL COOL A LITTLE COMPARED TO WHAT THEY HAVE BEEN
LATELY...BUT WILL STILL LIKELY REMAIN IN THE 90S FOR MUCH OF THE
AREA. ANOTHER SYSTEM WILL APPROACH FOR FRIDAY AND AN UNSETTLED
NORTHWEST FLOW PATTERN COULD KICK IN BRINGING DAILY CHANCES FOR
THUNDERSTORMS AND HAVING THE POTENTIAL TO KEEP TEMPERATURES IN THE
UPPER 80S TO LOW 90S INSTEAD OF GETTING EVEN HOTTER.

&&

.NEAR TERM TONIGHT/...

FORECAST FOCUS WILL BE AMOUNT OF THUNDERSTORM ACTIVITY THAT WORKS
SOUTH ACROSS OUR AREA OVERNIGHT AS WEAK COLD FRONT OVER SOUTHERN
WISCONSIN MOVES OUR WAY.  LINE OF THUNDERSTORMS HAVE DEVELOPED OVER
NORTHERN ILLINOIS AND RAPID REFRESH SPREADS THIS RAPIDLY SOUTHEAST
INTO CENTRAL INDIANA IN THE NEXT 3 TO 4 HOUR BEFORE WEAKENING THE
AREA OVERNIGHT.   LAPS AND UPPER AIR SOUNDINGS SHOWS A PRETTY GOOD
CAP ACROSS OUR REGION...SO THIS MAY BE A BIT OVERDONE.   PREFER
SLOWING SOUTHWARD PROGRESSION JUST A LITTLE AND KEEP BEST CHANCES
ACROSS THE NORTHERN HALF OF OUR REGION OVERNIGHT.  THIS GOES PRETTY
WELL WITH CURRENT FORECAST AND WILL ONLY MAKE MINOR ADJUSTMENTS TO
POPS.

DEWPOINTS OVER CENTRAL AND EASTERN SECTIONS WERE IN THE MIDDLE TO
UPPER 60S. WILL LOWER TEMPERATURES A DEGREE OR TWO MOST AREAS AS A
RESULT.

&&

.SHORT TERM /WEDNESDAY THROUGH FRIDAY/...
FORECAST FOCUS IS ON TEMPERATURES. GENERALLY SPEAKING GUIDANCE HAS
BEEN SEVERAL DEGREES TOO COOL RECENTLY AND FOLLOWED THIS TREND.
ALTHOUGH COLD FRONT WILL BE JUST ABOUT THROUGH THE AREA BY WEDNESDAY
MORNING AND COLDER TEMPERATURES WILL ADVECT IN AT 850 MB ON THURSDAY
AND FRIDAY...WITH A GREAT DEAL OF SUNSHINE THOSE DAYS AND DRY SOIL
STILL EXPECT TEMPERATURES TO REACH/EXCEED 90 FOR MOST OF THE AREA.
THIS AMOUNTED TO A DEGREE OR TWO ABOVE GUIDANCE WEDNESDAY AND A FEW
DEGREES ABOVE FOR THURSDAY AND FRIDAY.

ON PRECIPITATION CHANCES...KEPT SOME POPS IN THE SOUTHEAST WEDNESDAY
MORNING AND THE FAR SOUTH WEDNESDAY AFTERNOON AS THE COLD FRONT
SLOWLY MOVES OUT OF SOUTHERN INDIANA. AFTER THAT THE FORECAST IS DRY
THROUGH THURSDAY NIGHT WHEN A SLIGHT CHANCE SNEAKS INTO THE WEST AS
AN UPPER SHORTWAVE APPROACHES THE AREA. A LITTLE DISAGREEMENT
BETWEEN THE MODELS ON FRIDAY AS TO THE LOCATION OF THE SHORTWAVE
FORCING AND THUS WHETHER OR NOT TO INCLUDE PRECIP BUT FOR NOW
MAINTAINED THE GOING CHANCE FOR THUNDERSTORMS.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...

FOCUS IS ON CHANCES FOR RAIN...MAINLY FOR THIS WEEKEND. A LINGERING
FRONTAL BOUNDARY WILL BE THE FOCUS FOR CHANCES FOR SHOWERS AND
THUNDERSTORMS AS SEVERAL WAVES RIDE ALONG IT. OVERALL THE MODELS ARE
SIMILAR...BUT AS USUAL DIFFER ON DETAILS OF THE SMALLER WAVES. USED
HPC GUIDANCE FOR THIS PERIOD WHICH YIELDS CHANCES FOR RAIN SAT/SUN
AND DRIER WEATHER FOR EARLY NEXT WEEK. NEXT BIG QUESTION IS WILL THE
NINETY WEATHER STICK AROUND? NUDGED UP GUIDANCE A DEGREE OR TWO
BASED ON PAST VERIFICATIOBN WHICH PUTS THE INDY AREA JUST BELOW
90...BUT WOULD NOT BE SURPRISED IF EVEN WARMER TRENDS PREVAIL. TOO
EARLY TO TELL ATTM.

&&

.AVIATION /DISCUSSION FOR THE 030600Z TAFS/...

LARGE CONVECTIVE CLUSTER HAS DEVELOPED OVER NORTHERN ILLINOIS AHEAD
OF COLD FRONT. THIS EVENING/S UPPER AIR INDICATE THERE IS STILL A
RATHER STRONG CAP IN PLACE...SO NOT SURE HOW FAR SOUTHEAST THIS
CLUSTER WILL GET BEFORE DISSIPATING...BUT GIVEN THE CURRENT STRENGTH
OF THE CLUSTER...IT MAY BE AWHILE BEFORE IT FALLS APART. MODELS
INDICATE A DECENT LOW LEVEL JET FOR THIS TIME OF YEAR ACROSS THE
AREA OVERNIGHT...SO CONVECTIVE POTENTIAL MAY BE HIGHER THAN WOULD
NORMALLY BE EXPECTED. APPEARS THE BEST CHANCES FOR CONVECTION
DIRECTLY IMPACTING A TERMINAL OVERNIGHT WILL BE AT KLAF...WITH
LESSER CHANCES FARTHER SOUTH. MODEL DATA SUGGEST CONVECTIVE
POTENTIAL SHOULD TAPER OFF BY 031200Z-031300Z.

COLD FRONT EXPECTED TO PASS ACROSS THE TAF SITES DURING THE MID TO
LATE MORNING HOURS...ALTHOUGH THE WIND SHIFT ASSOCIATED WITH THE
FRONT LOOKS TO BE GRADUAL RATHER THAN SHARP. POTENTIAL EXISTS FOR
SOME MVFR CEILINGS TO DEVELOP IN THE VICINITY OF THE THE FRONTAL
ZONE AS WELL...BUT CONFIDENCE IS LOW.

&&

.IND WATCHES/WARNINGS/ADVISORIES...
IND...NONE.
