NWS Indianapolis, IN wrote its last area forecast discussion before this severe thunderstorm warning went out at May 10, 1:48 PM EDT, 1 hour 5 minutes earlier.

Area forecast discussion, May 10, 1:48 PM EDT, 1 hour 5 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
148 PM EDT TUE MAY 10 2011

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

&&

.SYNOPSIS...

A WARM FRONT WILL LIFT NORTHEAST ACROSS THE AREA TODAY AND THEN
STALL OUT. MEANWHILE AN UPPER RIDGE WILL BUILD INTO THE AREA FOR
MID WEEK...BEFORE AN UPPER LOW MOVES INTO THE AREA FOR THE
WEEKEND. THE UPPER RIDGE WILL BRING WARM AIR AND LOWER CHANCES FOR
RAIN...BUT COOLER CONDITIONS AND HIGHER CHANCES FOR RAIN WILL
RETURN WITH THE UPPER LOW THIS WEEKEND.

&&

.NEAR TERM /REST OF TODAY/...

UPDATE TO INCREASE POPS ACROSS N/NE COUNTIES LATER THIS AFTERNOON.

ANALYSIS AS OF 930 AM THIS MORNING DEPICTS A SLOW MOVING WARM
FRONT LIFTING NORTHWARD ACROSS THE FORECAST AREA...CURRENTLY
APPROACHING KIND ATTM. AS THE FRONT LIFTS NORTHEAST EARLY TODAY...
INSTABILITY WILL BE HIGHER...BUT CAP WILL ALSO STILL BE
AROUND...UNTIL AROUND 18 TO 19Z WHEN MODELS PROG IT TO BREAK. HAVE
THUS INCREASED POPS ACROSS THE NORTHEAST COUNTIES...AND SPC HAS
PLACE OUR EASTERN COUNTIES IN A SLIGHT RISK FOR DAMAGING
WINDS AND HAIL. ALSO FORECAST HODOGRAPHS EXHIBIT PRONOUNCED
VEERING OF WINDS WITH HEIGHT AND 40-50 KT OF DEEP NWLY SHEAR WHICH
WILL BE SUPPORTIVE OF SUPERCELLS WITH THE INITIAL STORM
DEVELOPMENT.

&&

.SHORT TERM /TONIGHT THROUGH FRIDAY/...

FOCUS IS ON CHANCES FOR RAIN THROUGH THE PERIOD. WITH THE BIG
PICTURE...THE MODELS ARE SIMILAR. HOWEVER THEY DIFFER IN TERMS OF
CONVECTION. AS WITH THE NEAR TERM...DO NOT HAVE A LOT OF FAITH IN
THEIR HANDLING OF CONVECTION BASED ON RECENT PERFORMANCE. WILL NOT
RELY ON A PARTICULAR MODEL.

THE FRONT SHOULD BE FAR ENOUGH NORTHEAST BY THIS EVENING TO IMPACT
ONLY THE FAR NORTHEAST FORECAST AREA. WILL USE LOW POPS
THERE...OTHERWISE DRY. ANY MCS DEVELOPMENT SHOULD BE NORTHEAST OF
THE AREA OVERNIGHT...SO WENT DRY ALL AREAS THEN. A BLEND OF
MOS/RAW MODEL TEMPS LOOK BEST OVERNIGHT GIVEN EXPECTED CONDITIONS.

THE UPPER RIDGE BEGINS TO MOVE OFF TO THE EAST WEDNESDAY
AFTERNOON AND LOSE ITS INFLUENCE. WITH THE EXPECTED INSTABILITY
FEEL THAT LOW POPS ARE WARRANTED ALL AREAS WEDNESDAY AFTERNOON.
WITH A RELATIVELY WARM START AND SUNSHINE...HIGHS IN THE MID 80S
LOOK GOOD...WHICH IS A BLEND OF MOS.

THE UPPER RIDGE WILL CONTINUE TO MOVE EAST INTO FRIDAY AS THE UPPER
LOW BEGINS ITS APPROACH. INSTABILITY WILL STILL BE AROUND. GIVEN
THESE CONVECTION WILL HAVE A CHANCE TO DEVELOP DURING THE PERIOD...SO
WENT LOW POPS INTO THURSDAY NIGHT. WENT A LITTLE HIGHER...BUT
STILL CHANCE CATEGORY...ON FRIDAY WITH THE UPPER LOW GETTING
CLOSER.

&&

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

ECMWF AND GFS BOTH AGREE ON DROPPING DEEP UPPER LOW ACROSS
CENTRAL INDIANA THIS WEEKEND...BUT DISAGREE ON IT/S EVOLUTION AND
DEPARTURE. ECMWF KEEPS THE UPPER LOW ACROSS INDIANA INTO
MONDAY...WHILE THE GFS DEPARTS THE SYSTEM TO THE EAST COAST WHILE
COOL...BROAD CYCLONIC NW FLOW CONTINUES. GIVEN ALL OF THIS WILL
KEEP CHANCES FOR SHOWERS AND ISOLATED THUNDERSTORMS IN THE
FORECAST THROUGH THE ENTIRE PERIOD. ALTHOUGH ISOLATED HEAVY RAIN
CANNOT BE RULED OUT...WIDESPREAD HEAVY RAIN WILL APPEAR UNLIKELY
GIVEN THIS PATTERN. STEADY LIGHTER RAINS SHOULD BE EXPECTED GIVEN
THIS PATTERN.

GIVEN THE EXPECTED CLOUDS AND RAIN...HAVE TRENDED WARMER THAN
MEXMOS ON LOWS AND COOLER THAN MEXMOS HIGHS.

&&

.AVIATION.../DISCUSSION FOR THE 10/18Z TAFS/...

THE MAIN CONCERN FOR THE TAF PACKAGE IS AFTERNOON CONVECTION. IT
APPEARS THAT THE AFTERNOON HEATING AND INSTABILITY WILL BE ENOUGH
TO TRIGGER PULSE STORMS THROUGH THE DAY. KLAF AND KHUF ALREADY
HAVE THUNDERSTORMS IN THE VICINITY. THIS ACTIVITY SHOULD TAPER OFF
AFTER SUNSET WHEN THEY LOSE AFTERNOON HEATING. OTHERWISE...VFR
CONDITIONS WILL PREVAIL FOR ENTIRE TAF PERIOD EXCEPT FOR POSSIBLE
DROPS TO MVFR CATEGORY WITH ANY STORMS.

OTHERWISE...JUST SOME MID AND HIGH LEVEL CLOUDS FOR THE REMAINDER
OF TAF PERIOD AS RIDGE BUILDS INTO THE FORECAST AREA. WINDS WILL BE
SOUTH/SOUTHWESTERLY AT 5 TO 10 MPH EXCEPT FOR ANY STRONG GUSTS
WITH ANY STORMS THIS AFTERNOON.

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