AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
112 PM EDT SAT JUN 12 2010

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

&&

.SYNOPSIS...

SHOWERS AND THUNDERSTORMS WILL REMAIN IN THE FORECAST THROUGH THE
WEEKEND AS A FRONTAL BOUNDARY REMAINS VIRTUALLY STATIONARY OVER
CENTRAL INDIANA. THE BOUNDARY WILL FINALLY MOVE SOUTH IN THE FORM
OF A COLD FRONT ON SUNDAY NIGHT/MONDAY MORNING BRINGING
TEMPERATURES CLOSER TO NORMAL FOR THE BEGINNING OF THE WEEK.

&&

.NEAR TERM /TODAY/...

APPARENT TEMPERATURES HAVE SURGED PAST 100 IN SOUTHWEST COUNTIES.
DO NOT EXPECT THEM TO DROP UNTIL LATE IN DAY...AND THIS IS BY FAR
THE WARMEST SO FAR THIS SEASON. ISSUED HEAT ADVISORY.

&&

.SHORT TERM /TONIGHT THROUGH MONDAY/...

SCATTERED SHOWERS AND THUNDERSTORMS WILL REMAIN IN THE FORECAST
THROUGH THE SHORT TERM AS THE PERSISTENT FRONTAL BOUNDARY REMAINS
OVER THE AREA. SITUATION CONTINUES TO BE A BIT TRICKY WITH TIMING
OF HEAVIEST RAINFALL AND POSSIBLE CONVECTION. HOWEVER...FELT
CONFIDENT ENOUGH TO INCREASE POPS THROUGH THE WEEKEND AS A WEAK
SURFACE LOW MOVES ACROSS THE AREA ON SATURDAY NIGHT/SUN
MORNING...AND THEN A COLD FRONT FINALLY SLIDES ACROSS CENTRAL
INDIANA ON SUNDAY NIGHT.

GFS/EURO SEEM TO HAVE BEST HANDLE ON DISTURBANCES THIS
WEEKEND...WHILE NAM/S POPS AND TEMPS ARE TOO LOW. LEANED TOWARD THE
HIGHER POPS OF THE GFS/EURO BECAUSE THE STATIONARY FRONT WILL LINGER
OVER A PRIME ENVIRONMENT. ATMOSPHERE IS PROGGED TO DESTABILIZE ONCE
AGAIN THIS AFTERNOON WITH AMPLE MOISTURE AND DAYTIME
HEATING...RESULTING IN MORE SCATTERED SHOWERS AND THUNDERSTORMS MUCH
LIKE YESTERDAY. ANTICIPATE A LULL IN ACTIVITY THIS EVENING...BUT IT
SHOULD RESUME ONCE AGAIN TONIGHT/TOMORROW MORNING AS A WEAK SURFACE
LOW DRIFTS ACROSS THE AREA. DYNAMICS WON/T BE IMPRESSIVE...BUT THE
SETUP OF THE ENVIRONMENT SHOULD BE DECENT ENOUGH FOR AN INCREASE IN
CONVECTION LATE TONIGHT/TOMORROW MORNING. CONTINUED TO ERR ON THE
HIGHER SIDE OF POPS THROUGH MONDAY MORNING AS RIDGE OF HIGH PRESSURE
OVER THE SOUTH FINALLY BREAKS DOWN AND STATIONARY FRONT MOVES SOUTH
IN THE FORM OF A COLD FRONT.

THE BEST CHANCE FOR SEVERE WEATHER STILL APPEARS TO BE THIS
AFTERNOON...BUT CANNOT BE ENTIRELY RULED OUT WITH FRONTAL PASSAGE
ON SUNDAY NIGHT.

AS FAR AS TEMPS...DISREGARDED NAM DUE TO IT/S POOR HANDLE ON
EVENTS. SO...STUCK CLOSE TO GFS THROUGH MONDAY WITH HIGHS IN THE
LOW 90S AND LOWS IN THE LOW 70S TODAY AND TOMORROW...AND THEN THE
POST FRONTAL DROP IN TEMPS ON MONDAY.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...

THE BEGINNING OF THE EXTENDED PERIOD WILL STILL BE PLAGUED BY
RAIN CHANCES THANKS TO THAT PESKY BOUNDARY. LATEST GUIDANCE SHOWS
THE BOUNDARY HOLDING FURTHER TO THE NORTH MONDAY NIGHT INTO EARLY
TUESDAY BEFORE FINALLY DROPPING TO THE SOUTH LATE TUESDAY. THERE
SEEMS TO BE ENOUGH OF A CONSENSUS BETWEEN THE EURO...GFS AND UKMET
TO KEEP AT LEAST CHANCE POPS IN THE FORECAST DURING THIS TIME.

AS FOR THE REST OF THE PERIOD, THERE SEEMS TO BE SOMEWHAT OF A
CONSISTENCY AMONG THE MODELS WITH RESPECT TO BUILDING A RIDGE OVER
THE REGION THROUGH THE END OF THE WORK WEEK. FROM TUES NIGHT ONWARD
HAVE KEPT FORECAST DRY. HIGH TEMPERATURES WILL BE IN THE 80S FOR THE
MAJORITY OF THE PERIOD.

&&

.AVIATION.../FOR 131800 TAF/...

MODELS CONCUR FRONT TO REMAIN JUST TO NORTH OF CENTRAL INDIANA
THROUGH FORECAST PERIOD. LIGHT BUT EXTREMELY HUMID SOUTH TO SOUTHWEST
FLOW CONTINUING OVER AREA. THUNDERSTORMS MAY FORM ALMOST ANY TIME
BUT BEST CHANCE WILL BE LATE AFTERNOON AND EVENING. HEAVY RAIN
REDUCING BOTH CEILINGS AND VISIBILITIES TO IFR POSSIBLE IN STORMS.

OTHERWISE...CEILINGS WILL RISE FROM MVFR TO VFR BY LATE AFTERNOON
AS MIXING OCCURS. THEY SHOULD STAY VFR INTO SUNDAY SINCE MOIST
LAYER IS DEEP AND CLOUDS WILL TEND TO FORM NEAR TOP OF IT.

VISIBILITIES SHOULD STAY 6SM OR HIGHER UNTIL AROUND 08Z...THEN
FOG WILL FORM. LOWEST VISIBILITIES WILL BE AROUND 3SM SINCE CLOUDS
SHOULD PREVENT IT FROM GETTING VERY DENSE. VISIBILITIES RECOVERING TO
6SM OR BETTER BY MID MORNING.

&&

.IND WATCHES/WARNINGS/ADVISORIES...
HEAT ADVISORY UNTIL 7 PM EDT THIS EVENING FOR INZ060-061-067>069.

...VERY MUGGY WEATHER OVER MUCH OF CENTRAL INDIANA THIS AFTERNOON...

HEAT INDICES WILL BE IN THE 90S OVER MAINLY THE SOUTHWEST PART OF
CENTRAL INDIANA THIS AFTERNOON.  HEAT INDICES IN THE 90S CALL FOR
EXTREME CAUTION WHEN ENGAGING IN OUTDOOR ACTIVITIES.

THE STEAMY WEATHER IS BEING PRODUCED BY A STALLED OUT WARM FRONT OVER
NORTHERN INDIANA WHICH HAS LEFT VERY HUMID AIR OVER THE CENTRAL AND
SOUTH PARTS OF THE STATE. MOIST GROUND FROM RECENT THUNDERSTORMS WAS
ALSO ADDING TO THE HUMIDITY.

TEMPERATURES ARE EXPECTED TO CLIMB TO NEAR 90 THIS AFTERNOON AND WHEN
COMBINED WITH HIGH HUMIDITY WILL RESULT IN VERY UNCOMFORTABLE
CONDITIONS.

HEAT INDICES ARE DETERMINED BY COMBINING THE AIR TEMPERATURE WITH THE
HUMIDITY.

HEAT ADVISORIES ARE POSSIBLE THIS AFTERNOON  AND ARE ISSUED WHEN THE
HEAT INDEX REACHES THE LOWER 100S.
