Areal Flood Warning 57, NWS Indianapolis, IN

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
545 AM EDT SUN JUN 26 2011

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

&&

.SYNOPSIS...

A RATHER ACTIVE WEATHER PATTERN HAS BEGUN ACROSS CENTRAL INDIANA
AND WILL REMAIN THAT WAY THROUGH THE BEGINNING OF NEXT WEEK. A
WARM FRONT WILL PUSH NORTH INTO THE FORECAST AREA...PRIMING THE
ENVIRONMENT FOR THUNDERSTORM DEVELOPMENT...AND THEN AN ASSOCIATED
COLD FRONT WILL MOVE THROUGH ON MONDAY NIGHT BRINGING THE BEST
CHANCES FOR SEVERE WEATHER.

&&

.NEAR TERM /EARLY MORNING AND TODAY/...

MCS HAS MOVED SOUTH OF AREA OVER THE LAST FEW HOURS...AND REMNANT
RAIN SHOWERS ARE ALL THAT/S LEFT ACROSS FORECAST AREA AT THIS
TIME. THE WARM FRONT THAT IS PROGGED TO MOVE NORTH INTO CENTRAL
INDIANA TODAY WILL STALL OUT FOR AWHILE OVER FAR SOUTHERN INDIANA.
AS A RESULT...KEPT LIKELY POPS CONFINED TO THE FAR SOUTHERN
COUNTIES FOR TODAY. KEPT CHANCE POPS EVERYWHERE ELSE...BUT THAT
MIGHT BE A BIT MUCH FOR THE NORTHERN COUNTIES...WHICH MAY HAVE TO
BE DROPPED TO SLIGHT CHANCE WITH MID MORNING UPDATE.

CURRENT THINKING IS THAT CLOUDS WILL BREAK UP FOR A BIT THIS
AFTERNOON...BUT THEY WILL QUICKLY BUILD BACK IN AGAIN AS
AFOREMENTIONED FRONT MOVES BACK NORTH IN THE FORM OF WARM FRONT
LATER TODAY.

TEMPS...WENT WITH A MAV/MET BLEND ACROSS THE NORTHERN 2/3 OF
FORECAST AREA. HOWEVER...TRENDED A FEW DEGREES BELOW GUIDANCE
ACROSS THE FAR SOUTHERN PORTIONS OF CENTRAL INDIANA DUE TO ANY
LINGERING CLOUDS/RAIN SHOWERS FROM THIS MORNING/S MCS.

&&

.SHORT TERM /TONIGHT THROUGH WEDNESDAY/...

THE FOCUS OF SHORT TERM CONTINUES TO BE POPS AND THUNDERSTORM
POTENTIAL.

WARM FRONT WILL CONTINUE IT/S NORTHWARD PROPAGATION THIS EVENING
ALONG WITH VERY MOIST AIR. THIS PART OF FORECAST IS WHERE
CONFIDENCE IS A BIT LOWER. ANOTHER MCS SHOULD DEVELOP OVER THE
LOWER MIDWEST THIS EVENING/TONIGHT AS A MID-LEVEL SHORT WAVE MOVES
THROUGH. HOWEVER...MODELS ARE ALL DIFFERING IN TIMING OF THIS
SHORTWAVE. CURRENT THINKING THOUGH IS THAT SHOWERS AND
THUNDERSTORMS WILL MOVE THROUGH CENTRAL INDIANA LATE TONIGHT.

ENVIRONMENT WILL ONCE AGAIN BECOME PRIMED TOMORROW AHEAD OF COLD
FRONT TOMORROW NIGHT. WINDS WILL VEER TO THE SOUTHWEST TOMORROW
AFTERNOON...BRINGING IN VERY WARM AIR. TRENDED ON THE WARMER SIDE
OF GUIDANCE AND TOPPED HIGHS OFF IN THE UPPER 80S/LOW 90S OVER
FORECAST AREA. CAPES WILL BE VERY IMPRESSIVE WITH READINGS AS HIGH
AS 5000 J/KG. SO...THE COLD FRONT WILL HAVE A VERY UNSTABLE
ENVIRONMENT TO WORK WITH WHEN IT MOVES THROUGH TOMORROW NIGHT.

ONE NOTE THOUGH...VORTICITY DOES NOT LOOK AS IMPRESSIVE ALONG AND
AHEAD OF THE COLD FRONT AS PREVIOUS RUNS. WESTERLY WINDS IN THE
MID LEVELS ARE STILL DECENT THOUGH...BUT THIS MAY STILL BE
SOMETHING TO KEEP IN MIND.

TEMPS...TRENDED ON THE HIGHER SIDE OF GUIDANCE TONIGHT THROUGH
TOMORROW...AND THEN BELOW GUIDANCE FOR THE REMAINDER OF SHORT TERM
IN WAKE OF COLD FRONT.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/...

HIGH PRESSURE SHOULD ALLOW FOR MOSTLY DRY WEATHER MIDWEEK THROUGH
SATURDAY. ALTHOUGH...A FRONT WILL BE GETTING A BIT CLOSER FROM THE
NORTHWEST LATE WEEK AND EARLY WEEKEND...DRY FORECAST LOOKS GOOD FOR
NOW. WITH UPPER RIDGE BUILDING IN FROM THE SOUTHWEST...ABOVE NORMAL
HPC TEMPERATURES LOOK EASILY ATTAINABLE.

&&

.AVIATION.../DISCUSSION FOR THE 12Z TAFS/...

VFR CONDITIONS EXPECTED TODAY AND THIS EVENING...HOWEVER MVFR FOG
WILL BE POSSIBLE OVERNIGHT.

DEPARTING MCS EXPECTED TO WANE AND DISSIPATE DURING THE FIRST FEW
HOURS OF THE TAF PERIOD. WARM FRONTAL BOUNDARY SOUTHWEST OF
INDIANA WILL ALLOW FOR WARM AIR ADVECTION AND OVERRUNNING OF
CLOUDS TODAY. FORECAST SOUNDINGS SHOW CCLS NEAR 3-4K FT AND TIME
HEIGHT SHOW GOOD MOISTURE IN THE LOWER LEVELS. LITTLE LIFT IS
AVAILABLE IN THE WAKE OF THE DEPARTING SHORT WAVE AND FORECAST
SOUNDINGS FAIL TO INDICATE STEEP ENOUGH LAPSE RATES FOR TSRA
CONCERNS. THUS JUST SOME CLOUDS TODAY.

WARM FRONT REMAINS SOUTHWEST OF INDIANA OVERNIGHT AND TAF SITES
WILL BE IN IDEAL SPOT FOR FOG FORMATION. SURGE OF HIGHER DEW POINT
TEMPERATURES IS ALSO EXPECTED TO ARRIVE AS THE FRONT TRIES TO
SLOWLY PUSH NORTHWARD TONIGHT. THUS WILL INCLUDE THE MVFR FOG FOR NOW.

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