AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
616 AM EDT TUE JUN 22 2010

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

&&

.SYNOPSIS...
A PERSISTENT FRONTAL BOUNDARY AND SEVERAL WEAK IMPULSES IN THE
UPPER LEVEL FLOW WILL KEEP SHOWER AND THUNDERSTORM CHANCES IN THE
FORECAST THE NEXT FEW DAYS. HOT TEMPS WILL CONTRIBUTE TO AN
UNSTABLE ENVIRONMENT...INCREASING THE LIKELIHOOD FOR POPUP
CONVECTION THROUGH MID WEEK.

&&

.NEAR TERM /THIS MORNING/...
CURRENT RADAR MOSAIC IS SHOWING WIDESPREAD CONVECTION ACROSS
CENTRAL INDIANA...AND THIS ACTIVITY WILL PERSIST THROUGH DAYBREAK
AS BOUNDARY REMAINS DRAPED ACROSS NORTHERN ILLINOIS AND CENTRAL
INDIANA. CONVECTION HAS BASICALLY LINED OUT WITH EMBEDDED CELLS
EXHIBITING SOME SUPERCELLULAR BEHAVIOR.

&&

.SHORT TERM /TODAY THROUGH THURSDAY/...

GFS/NAM/EURO ARE ALL SHOWING SOUTHWEST FLOW AND HOT/HUMID
CONDITIONS ACROSS CENTRAL INDIANA ONCE AGAIN THIS AFTERNOON. THE
PERSISTENT FRONTAL BOUNDARY SHOULD SET UP FURTHER NORTH ACROSS
SOUTHERN WISCONSIN AND SOUTHERN MICH TODAY...BUT SB CAPES IN
EXCESS OF 4K AND LI/S AS LOW AS -11 WILL KEEP THE THREAT FOR POPUP
CONVECTION IN CENTRAL INDIANA. THE MAIN THREAT SHOULD BE DAMAGING
WINDS. HEAT INDICES WILL APPROACH THE 100 DEGREE MARK OVER
SOUTHWEST PORTIONS OF FORECAST AREA...SO WENT WITH HEAT ADVISORY
ONCE AGAIN TODAY.

CONVECTION SHOULD TAPER OFF TONIGHT WITH LOSS OF DIURNAL
HEATING...BUT KEPT CHANCE POPS IN TOMORROW AS CENTRAL INDIANA FALLS
IN A WARM SECTOR OF A SURFACE LOW PASSING OVER THE UPPER MIDWEST.
PATTERN WILL CHANGE TOMORROW NIGHT AS A COLD FRONT SLIDES ACROSS THE
AREA...BRINGING A HALT TO THE ACTIVE WEATHER THROUGH THE END OF THE
WEEK.

TEMPS...MODELS HAVE GOOD HANDLE ON TEMPS...SO WENT WITH A BLEND
THROUGH THE SHORT TERM. TRENDED ON THE HIGHER SIDE OF GUIDANCE
TODAY AND TOMORROW WITH SOUTHWEST FLOW. THURSDAY...STUCK CLOSE TO
GUIDANCE WITH HIGHS DROPPING A BIT INTO THE UPPER 80S IN WAKE OF
WEDNESDAY NIGHT/S COLD FRONT. AS FAR AS LOWS...STUCK WITH GUIDANCE
AND KEPT THEM IN THE LOW 70S.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...

SIGNAL HAS STRENGTHENED SOMEWHAT IN LONGER RANGE MODELS THAT A
SIGNIFICANT BREAK IN THUNDERSTORM ACTIVITY CAN BE EXPECTED AT THE
END OF THE WEEK THROUGH SATURDAY NIGHT...AS BROAD SURFACE HIGH
SHUTTLES EASTWARD ACROSS THE REGION. AFTER A SHORT REPRIEVE FROM
THE HEAT ON THURSDAY...ANOTHER WARMUP BACK INTO THE UPPER 80S AND
LOW 90S IS EXPECTED FOR THE WEEKEND.

BACKED OFF HPC/MEX GUIDANCE CLOSER TO ENSEMBLE MEANS...AS AGAIN IT
APPEARS THAT GUIDANCE IS STRUGGLING WITH WET CONDITIONS WHICH WILL
HELP TO MODERATE HEATING SOMEWHAT.

PRECIP CHANCES RETURN SUNDAY AND SUNDAY NIGHT AS A FRONT SAGS
SOUTH THROUGH THE REGION.

&&

.AVIATION.../221200 TAF ISSUANCE/...
THUNDERSTORMS CONTINUE TO IMPACT THE AREA ALONG A QUASI STATIONARY
BOUNDARY EARLY THIS MORNING. EXPECT STORMS WILL DIMINISH BY MID
MORNING WITH SKIES BECOMING PARTLY CLOUDY. WITH THE ATMOSPHERE
ONCE AGAIN BECOMING HIGHLY UNSTABLE LATER THIS AFTERNOON AND THE
BOUNDARY LIFTING ONLY SLOWLY NORTH...SCATTERED CONVECTION WILL
DEVELOP FOR THE LATE AFTERNOON AND EVENING. WILL CARRY CB MENTION
AT ALL TERMINALS...WITH LATER SHIFTS EMPLOYING MORE DETAILS AS
THE PATTERN EVOLVES. CONVECTION SHOULD THEN SHIFT INTO NORTHERN
INDIANA ALONG THE BOUNDARY TONIGHT. WINDS WILL GENERALLY BE
SOUTH/SOUTHWEST FOR MUCH OF THE FORECAST PERIOD.
