Area forecast discussion, Aug 4, 11:43 AM EDT, 6 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
1143 AM EDT WED AUG 4 2010

.UPDATE...
THE NEAR TERM SECTION HAS BEEN UPDATED BELOW.

&&

.SYNOPSIS...
THE MAIN FOCUS OF THE SHORT TERM FORECAST IS THE EXCESSIVE HEAT
ACROSS CENTRAL INDIANA AS A HOT AND HUMID AIRMASS OVERTAKES THE
AREA. TEMPERATURES ARE EXPECTED TO TOP OFF IN THE TRIPLE DIGITS
THIS AFTERNOON WITH HEAT INDICES REACHING A DANGEROUS LEVEL OF 105
TO 112 DEGREES ACROSS THE SOUTHWEST PORTIONS OF THE FORECAST
AREA. IN ADDITION...THERE IS A THREAT FOR SEVERE WEATHER AS A COLD
FRONT PUSHES THROUGH A VERY UNSTABLE AIRMASS LATER TODAY AND
TONIGHT. THERE WILL BE A BREAK FROM THE HEAT STARTING TOMORROW IN
WAKE OF THE AFOREMENTIONED COLD FRONT. HIGHS WILL FALL INTO THE
MID TO UPPER 80S WITH LESS HUMID CONDITIONS. FURTHER
OUT...PLEASANT CONDITIONS WILL RETURN FOR THE WEEKEND AS HIGH
PRESSURE BUILDS ACROSS THE GREAT LAKES REGION.

&&

.NEAR TERM /THIS AFTERNOON/...
HAVE REMOVED LAFAYETTE TO KOKOMO FROM HEAT ADVISORY AS THE RESULT
OF COOLING AND DRYING THUNDERSTORM OUTFLOW WINDS AS WELL AS CLOUD
DEBRIS SHOULD KEEP THESE AREAS BELOW HEAT ADVISORY CRITERIA.

SAME BOUNDARY PUSHING SOUTHEAST ACROSS HEART OF FORECAST AREA WILL
CREATE WIND SHIFT AND SLOW HEAT AND HUMIDITY IN INDY METRO BUT
EXPECT IMPACTS TO BE MORE LIMITED THAN FURTHER NORTH. AS A RESULT
KEEPINH HEAT ADVISORY HERE BUT LOWERING EXPECTED HIGH TEMP A FEW
DEGREES.

SOUTHEAST COUNTIES...COLUMBUS...SEYMOUR...NORTH VERNON...NASHVILLE
HAVE BEEN ADDED TO HEAT WARNING. THESE AREA NOT LIKELY TO BE IMPACTED
BY THE OUTFLOW BOUNDARY OTHER THAN TO HELP DEWPOINT POOLING AHEAD
OF IT. AT SAME TIME TEMPS THERE ALREADY AT 90 AND HEAT INDICES
ALREADY AT OR ABOVE 100 AND SHOULD EASILY ECLIPSE 105 HI.

FOR PRECIPITATION THIS AFTERNOON...CONTINUED LIKELY FROM ANDERSON
AND MUNCIE TO WINCHESTER AS OUTFLOW BOUNDARY DEVELOPS STORMS UP
THERE. RESPITE THEN EXPECTED THERE BEFORE NEW DEVELOPMENT THIS
AFTERNOON. REMAINDER OF AREA STILL EXPECT EVENTUAL SCATTERED STORM
DEVELOPMENT LATE AFTERNOON TO PRESS SLOWLY SOUTH THIS EVENING. CAP
OF WARM AIR ALOFT LIKELY TO KEEP SOUTHERN COUNTIES DRY UNTIL EVENING.

&&

.SHORT TERM /WEDNESDAY INTO THURSDAY/...
THE MAIN FOCUS IS THE EXCESSIVE HEAT.

A HEAT ADVISORY REMAINS IN EFFECT FOR ALL OF CENTRAL INDIANA.
DECIDED TO UPGRADE TO HEAT WARNING ACROSS THE SOUTHWEST PORTIONS
OF THE AREA. AT THIS TIME...MIN APPARENT TEMPS WILL MEET
CRITERIA...AND MAX APPARENT TEMPS WILL BE CLOSE. SO...FELT THIS
WARRANTED WARNING ACROSS THOSE COUNTIES...AND WARNING MAY HAVE
TO BE EXTENDED FURTHER NORTH.

GFS/EURO/NAM ALL SHOW FRONTAL BOUNDARY SITUATED OVER NORTHERN
PORTIONS OF WARNING AREA THROUGH THIS AFTERNOON. IT WILL FINALLY
PUSH THROUGH AS A COLD FRONT TONIGHT. LIFT IS NOT VERY
IMPRESSIVE...BUT THE FRONT WILL BE MOVING INTO A HIGHLY UNSTABLE
AIRMASS. SO...THERE IS A THREAT FOR SOME SEVERE WEATHER ONCE AGAIN
TONIGHT. SPC HAS NORTHERN TWO-THIRDS OF FORECAST AREA UNDER SLIGHT
RISK THROUGH TOMORROW MORNING. ONE CAVEAT IS THE -6 DEGREE TEMPS
AT 500MB...WHICH COULD INHIBIT POTENTIAL FOR SEVERE WEATHER.

THERE WAS A BIT OF DISCREPANCY BETWEEN THE NAM AND GFS/EURO
REGARDING TEMPS AND DEWPOINTS FOR TODAY. THE NAM HAD HIGHER
DEWPOINTS IN THE UPPER 70S WITH HIGHS JUST A BIT LOWER THAN THE
GFS/EURO. CONSIDERING THE WEATHER PATTERN THE LAST FEW
DAYS...LIKED THE HIGHER DEWPOINTS OF THE GFS/EURO. SO...LEANED
TOWARD THE MID 70S IN THE GRIDS FOR TODAY AND TONIGHT. CARRIED MID
TO UPPER 60S THROUGH THE END OF THE WEEK...THESE MAY HAVE TO BE
LOWERED...BUT HESITANT TO GO MUCH LOWER AT THIS TIME. AS FAR AS
TEMPS...LEANED TOWARD THE HIGHER NUMBERS OF THE GFS/EURO. UPPER
90S/LOW TRIPLE DIGITS DID NOT SEEM UNREASONABLE WITH 850 TEMPS IN
THE 20-22C RANGE.

FRIDAY...LESS HUMID AIR AND COOLER TEMPS /MID TO UPPER 80S/ WILL
PREVAIL BEHIND THE AFOREMENTIONED COLD FRONT. PLEASANT CONDITIONS
WILL BE THE NORM THROUGH THE WEEKEND.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
CANADIAN HIGH PRESSURE BUILDS INTO THE GREAT LAKES AND OHIO VALLEY
REGION AND PUSHES FRONTAL PRECIPITATION ALL THE WAY TO GULF STATES
SO VERY PLEASANT CONDITIONS LIKE LAST WEEKEND SHOULD OCCUR. GFS
HINTS AT SOME SCATTERED SHOWERS SATURDAY BUT IF THESE OCCUR THEY
SHOULD REMAIN TO OUR NORTH. MONDAY TUESDAY TIME FRAME MAY BECOME
UNSETTLED BUT FOR MOMENT HAVE KEPT THESE DRY UNTIL CONSISTENT
PATTERN ESTABLISHES.

&&

.AVIATION /DISCUSSION FOR 041200Z TAFS/..
INITIAL AREA OF THUNDERSTORMS OVER NORTHERN ILLINOIS IS TRACKING A
LITTLE FARTHER NORTH THAN EXPECTED AND IT SHOULD PASS NEAR OR JUST
OF KLAF NEAR OR SHORTLY AFTER 14Z.  WILL START VCTS AT KLAF AND
CONTINUE IT FOR THE REST OF THE DAY AS SCATTERED TO NUMEROUS
THUNDERSTORMS WILL MOVE ACROSS NORTHERN PARTS OF CENTRAL INDIANA.

AT KLAF AND KIND ONSET OF THUNDERSTORMS WILL BE SLOWER WITH BEST
CHANCES LATE TODAY AND EARLY TONIGHT. AT KBMG MAIN BEST CHANCES OF
THUNDERSTORMS WILL BE TONIGHT.  MODELS SHOW CAPES OF UP TO 3500
J/KG...BUT AIRMASS IS QUITE CAPPED OVER CENTRAL AND SOUTHERN
SECTIONS AT LEAST TODAY WHICH WILL DELAY ONSET OF THUNDERSTORMS.
SOME MVFR FOG EARLY THIS MORNING AND AGAIN OVERNIGHT.

&&

.IND WATCHES/WARNINGS/ADVISORIES...
HEAT ADVISORY UNTIL 8 PM EDT THIS EVENING FOR INZ028-030-035>042-
