AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
436 AM EDT WED MAR 28 2012

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

&&

.SYNOPSIS...

A LINE OF SHOWERS AND THUNDERSTORMS ALONG A COLD FRONT WILL
MOVE ACROSS CENTRAL INDIANA EARLY THIS MORNING...QUICKLY FOLLOWED
BY HIGH PRESSURE THIS AFTERNOON. THE RIDGING WILL RESULT IN DRY
WEATHER THROUGH FRIDAY WHEN THE NEXT DISTURBANCE ENTERS THE
FORECAST AREA. BEYOND THAT...QUIET CONDITIONS FOR THE REMAINDER OF
THE WEEKEND...AND THEN ANOTHER SYSTEM OVER THE GREAT LAKES REGION
IS PROGGED FOR MONDAY.  ITS ASSOCIATED COLD FRONT WILL TRIGGER
THUNDERSTORM ACTIVITY ACROSS CENTRAL INDIANA.

&&

.NEAR TERM /THIS MORNING AND TODAY/...

THE MAIN FOCUS OF THE NEAR TERM FORECAST IS A LINE OF SHOWERS WITH
ISOLATED EMBEDDED THUNDERSTORMS CURRENTLY MOVING INTO NORTHERN
PORTIONS OF CENTRAL INDIANA.

AS MENTIONED ABOVE...THUNDERSTORMS HAVE BEEN ISOLATED IN NATURE
AND ARE HAVING A TOUGH TIME INTENSIFYING DUE TO LACK OF FORCING.
AS A RESULT...SEVERE WEATHER IS NOT EXPECTED. ENVIRONMENT IS NOT
EVEN CONDUCIVE TO STRONG THUNDERSTORMS FOR THAT MATTER.

THIS WEAK CONVECTION SHOULD BE THROUGH THE FORECAST AREA BY MID
MORNING IF NOT SOONER. THE SURFACE LOW/S CENTER IS TRACKING OVER
THE GREAT LAKES...SO ANY ASSOCIATED WRAPAROUND MOISTURE WITH THAT
WILL STAY WELL NORTH OF CENTRAL INDIANA. AS A RESULT...CLOUDS WILL
SCATTER OUT LATER THIS MORNING...AND SUNNY SKIES WILL PREVAIL FOR
THE REMAINDER OF THE DAY.

TEMPS...MODELS DO NOT SEEM TO BE ACCOUNTING FOR CLEARING VERY
WELL...THUS SEEM A TAD LOW ON TODAY/S HIGHS. AS A RESULT...TRENDED A
FEW DEGREES ABOVE GUIDANCE DUE TO SUFFICIENT SUNSHINE LATER TODAY.

&&

.SHORT TERM /TONIGHT THROUGH FRIDAY/...

THE MAIN FOCUS OF THE SHORT TERM IS THE NEXT ROUND OF SHOWERS AND
THUNDERSTORMS ON FRIDAY.

RIDGE WILL RE-ESTABLISH ITSELF ACROSS FORECAST AREA TONIGHT
BRINGING DRY CONDITIONS THROUGH FRIDAY. HOWEVER...THE RIDGE WILL
BREAK DOWN ON THURSDAY NIGHT AS A 500 MB SHORTWAVE APPROACHES
CENTRAL INDIANA. THE GFS AND EURO ARE A TAD MORE PROGRESSIVE THAN
THE NAM IN REGARD TO PRECIP ON THURSDAY NIGHT...BUT INCREASING
ISENTROPIC LIFT SUPPORTS POPS AS EARLY AS FRI 06Z. THE BEST LIFT
WILL OCCUR IN THE FRI 12-18Z TIME FRAME AS SHORT WAVE AND SURFACE
LOW PASS OVER CENTRAL INDIANA. SO...INTRODUCED DEFINITE POPS INTO
GRIDS DURING THAT PERIOD...WHICH MAY HAVE TO BE EXTENDED INTO
FRIDAY NIGHT DEPENDING ON POSITION OF ASSOCIATED COLD FRONT.

TEMPS...STUCK WITH A BLEND UNTIL FRIDAY. THAT/S WHEN MODELS
STARTED HAVING A LITTLE TROUBLE WITH THE AFOREMENTIONED
DISTURBANCE. TRENDED ON THE COOLER SIDE FOR DAYTIME HIGHS...AND
LEANED ON THE WARMER SIDE FOR FRIDAY NIGHT LOWS DUE TO INCREASED
CLOUD COVER.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY NIGHT/...

THIS PERIOD BEGINS WITH SOME REMAINING LOW CHANCES FOR POPS AS FRONT
IS PROGGED TO BE DROPPING SOUTH OF THE AREA BY SATURDAY AFTERNOON.
MODELS HAVE BEEN INCREASINGLY PROGRESSIVE WITH THIS FRONT SO HAVE
BACKED OFF ON POPS SLIGHTLY FOR SATURDAY. UPPER RIDGING BUILDS IN
EARNEST BY SATURDAY NIGHT...AND PROVIDES QUIET DRY AND WARMER
WEATHER FOR CENTRAL INDIANA THROUGH SUNDAY NIGHT. ANOTHER FRONT IS
PROGGED TO APPROACH THE REGION SUNDAY NIGHT AND CROSS THE AREA
MONDAY INTO MONDAY EVENING...BRINGING CHANCES FOR THUNDER BACK INTO
THE FORECAST. RIDGE BUILDS BACK IN BY TUESDAY.

&&

.AVIATION /DISCUSSION FOR 280600Z TAF ISSUANCE/...

0830Z UPDATE...REMOVED LLVL WIND SHEAR AND TEMPO/D IN SHOWERS WITH
CB FOR 10-12Z...BASED ON CURRENT RADAR TRENDS. PREVIOUS DISCUSSION
FOLLOWS.

VFR CONDITIONS EXPECTED THROUGHOUT THE FORECAST PERIOD.

FRONTAL BOUNDARY APPROACHING THE REGION EARLY THIS MORNING WITH A
LINE OF SCATTERED CONVECTION. AIRMASS IS DRIER AND MORE STABLE OVER

ISOLATED OVER THE NEXT SEVERAL HOURS AS IT MOVES INTO THE FORECAST
AREA. HAVE CONTINUED WITH A VCSH/CB MENTION AT ALL TERMINALS IN A 3
TO 4 HOUR WINDOW THROUGH MID MORNING.

CLOUDS SHOULD QUICKLY CLEAR BY MIDDAY AS DRIER AIR ADVECTS INTO THE
REGION BEHIND THE FRONT. PRESENCE OF STRONGER WINDS ALOFT THROUGH
THE DAY AND MIXING LEVELS UP TO AROUND 5KFT WILL PROMOTE W/NW WIND
GUSTS AT 25-30KTS FOR MUCH OF THE AFTERNOON. WINDS WILL VEER TO
NORTHERLY AND LIGHTEN DURING THE EVENING AS A RIDGE OF HIGH
PRESSURE EXPANDS INTO THE REGION FROM THE NORTHWEST.
