AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
100 PM EDT TUE JUN 21 2011

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

&&

.SYNOPSIS...

A COLD FRONT WILL MOVE THROUGH THE AREA ON WEDNESDAY AS AN UPPER
LOW MOVES SLOWLY THROUGH THE GREAT LAKES. THIS WILL KEEP CHANCES
FOR RAIN AROUND THROUGH THURSDAY. ANOTHER FRONT WILL MOVE IN ON
SATURDAY...BRINGING ANOTHER CHANCE FOR RAIN.

&&

.NEAR TERM /THIS AFTERNOON/...LARGE OUTFLOW OVER EASTERN ILLINOIS
AND WESTERN KENTUCKY CONTINUES TO PUSH EAST...GETTING READY TO
ENTER CENTRAL INDIANA THIS AFTERNOON. 12Z ILX SOUNDING SHOWS
700MN TEMPS BELOW 10C...BUT A SLIGHT INVERSION ABOVE THAT LEVEL.
CONVECTIVE TEMPERATURES IN THE MIDDLE AND UPPER 80S ACROSS CENTRAL
INDIANA ARE EXPECTED TO BE REACHED IN THE NEXT 2-3 HOURS...AND AS
THIS BUOYANT AIR INTERACTS WITH THE BOUNDARY...THUNDERSTORMS ARE
EXPECTED TO DEVELOP. RAPID REFRESH AND NAM BOTH SUGGEST CONVECTION
DEVELOPING ACROSS THE FORECAST AREA THIS AFTERNOON. HAVE RAISED
POPS THIS AFTERNOON AFTER 18Z...AND CUT POPS PRIOR TO 18Z AND
PRECIP IS NOT EXPECTED TO DEVELOP UNTIL THEN.

GIVEN THE FULL SUN AND WARM AIR IN PLACE OVER CENTRAL INDIANA
HAVE RAISED HIGH TEMPERATURES BY 2-3 DEGREES...ALBEIT TEMPERATURES
MAY ONLY REACH THOSE HIGHS BRIEFLY AS CONVECTION COOLS THINGS OFF.

&&

.SHORT TERM /TONIGHT THROUGH FRIDAY/...

FOCUS CONTINUES TO BE ON CHANCES FOR RAIN. WILL CONTINUE TO USE
GFS/12Z ECMWF FOR REASONS NOTED ABOVE.

WITH UPPER ENERGY MOVING THROUGH THE AREA TONIGHT AND INSTABILITY
AROUND...FEEL LIKELY POPS ARE STILL WARRANTED. RAIN COOLED AIR
WILL BRING TEMPERATURES DOWN TO A BLEND OF GUIDANCE NUMBERS.

THE COLD FRONT WILL MOVE THROUGH THE AREA ON WEDNESDAY. BETTER
INSTABILITY WILL BE ACROSS THE EASTERN FORECAST AREA...SO
CONTINUED LIKELY POPS THERE AND CHANCE ELSEWHERE. MAV TEMPERATURES
LOOK REASONABLE MOST AREAS...BUT LOOK A BIT TOO WARM ACROSS THE
SOUTH GIVEN EXPECTED SKY COVER AND PRECIPITATION.

AS THE UPPER LOW MOVES TO THE NORTH WEDNESDAY NIGHT THROUGH
THURSDAY NIGHT...CHANCES FOR RAIN WILL CONTINUE ACROSS THE AREA.
GIVEN THE LIMITED STRENGTH OF THE FORCING WITH THE LOW ACROSS THE
LAKES...WENT CHANCE POPS ALL AREAS...WITH HIGHEST POPS ACROSS THE
NORTHERN FORECAST AREA CLOSER TO THE LOW. INSTABILITY DIMINISHES
THROUGH THE PERIOD SO HAVE MAINLY SHOWERS THROUGH THE PERIOD.

FORCING AND MOISTURE LOOK TO BE LIMITED ENOUGH TO GO DRY ON FRIDAY
AS THE LOW BEGINS ITS EXIT.

&&

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

FOR THE MOST PART STUCK CLOSE TO HPC GUIDANCE WITH SOME ADJUSTMENTS
TO POPS BASED ON THE ENSEMBLES. BROUGHT CHANCES OF RAIN BACK IN FOR
SATURDAY AND SATURDAY NIGHT AS A FRONT COULD STRETCH EAST INTO THE
AREA FROM THE PLAINS.

&&

.AVIATION.../DISCUSSION FOR THE 211800Z/...

VFR CONDITIONS EXPECTED EARLY THIS AFTERNOON...DETERIORATING TO
MVFR OR IFR WITH ANY TSRA PASSAGE THIS EVENING. PATCHY MVFR FOG
POSSIBLE TONIGHT WITH A RETURN TO VFR AFTER DAYTIME MIXING BEGINS
ON WEDNESDAY.

CONVECTION IS BEGINNING ACROSS CENTRAL INDIANA AS THE WARM HUMID
AIR MASS REACHES CONVECTIVE TEMPERATURES AND INTERACTS WITH THE
OUTFLOW CROSSING THE STATE. TSRA ARE EXPECTED TO INCREASE IN
COVERAGE THIS AFTERNOON AND GFS/NAM SUGGEST S/W INTERACTION WITH
THE WARM AIR MASS. TIME SECTIONS SHOW DEEPLY SATURATED COLUMN AND
GOOD LIFT AVAILABLE THROUGH THE EVENING HOURS PUSHING THROUGH
CENTRAL INDIANA. FOR NOW WILL HOLD OFF ON THUNDER MENTION AND
UPDATE THAT WHEN STORMS ARE IMMINENT. AGAIN MVFR TO IFR CONDITIONS
ARE EXPECTED WITH ANY THUNDERSTORM THAT STRIKES A TAF SITE.

COLUMN DRIES OUT CONSIDERABLY IN THE WAKE OF THE CONVECTION
OVERNIGHT AND WITH LINGERING MOISTURE FROM EXPECTED PRECIPITATION
HAVE INCLUDED MVFR FOG...PARTICULARLY AT THE TYPICAL RURAL TROUBLE SPOTS.

WARM MIXING BEGINS ON WEDNESDAY MORNING AND WILL MIX OUT ANY FOG
AND COMMENCE WARM SOUTHERLY FLOW AND CU BUILD UPS AGAIN.
