AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
332 AM EDT WED APR 17 2013

.UPDATE...
THE SYNOPSIS...NEAR TERM...SHORT TERM AND LONG TERM SECTIONS HAVE
BEEN UPDATED BELOW.

&&

.SYNOPSIS...

ISSUED AT 327 AM EDT WED APR 17 2013

A FRONTAL SYSTEM STALLED NEAR THE OHIO RIVER IS EXPECTED TO MOVE
NORTH ACROSS THE FORECAST AREA TONIGHT. STRONG LOW PRESSURE IS
EXPECTED TO MOVE THROUGH THE GREAT LAKES THURSDAY NIGHT AND
FRIDAY...BRINGING A COLD FRONT THROUGH THE AREA. IN THE WAKE OF THIS
FRONT...HIGH PRESSURE IS EXPECTED TO BUILD INTO THE AREA BY NEXT
WEEKEND AND INTO EARLY NEXT WEEK. ANOTHER FRONTAL SYSTEM MAY AFFECT
THE AREA BY NEXT TUESDAY.

&&

.NEAR TERM /THIS MORNING THROUGH TODAY/...

ISSUED AT 327 AM EDT WED APR 17 2013

FRONTAL BOUNDARY REMAINS JUST SOUTH OF THE OHIO RIVER AS OF 230 AM.
DESPITE THAT...SCATTERED CONVECTION CONTINUES TO DEVELOP AND MOVE
ACROSS SOUTHERN PORTIONS OF THE FORECAST AREA...AND ADDITIONAL
STORMS CONTINUE IN THE NORTHERN WABASH VALLEY.

MESOANALYSIS INDICATES INSTABILITY GRADIENT REMAINS NORTH OF THE
BOUNDARY AND DRAPED OVER FAR SOUTHERN COUNTIES...LIKELY CONTRIBUTING
TO THE PERSISTENCE OF STORMS. PRESENCE OF THE DEEPER LIFT AND WARM
ADVECTION SHOULD ENABLE CONVECTION TO PERSIST THROUGH EARLY THIS
MORNING. WILL MAINTAIN LIKELY TO SCATTERED THUNDERSTORM COVERAGE
THROUGH EARLY THIS MORNING...WITH A DECREASE IN COVERAGE ANTICIPATED
TOWARDS DAYBREAK AS THE AXIS OF LIFT SHIFTS NORTH AND LOW LEVEL
FORCING WEAKENS IN RESPONSE TO SUBTLE RIDGING ALOFT.

AS FOR THE REST OF THE DAY SCATTERED CHANCES FOR SHOWERS AND
THUNDERSTORMS WILL PERSIST HOWEVER NOT ANTICIPATED TO BE AS
WIDESPREAD AS THEY WERE TUESDAY NIGHT. GUIDANCE REALLY HAS NOE
HANDLE ON THE NEXT 24 HOURS...AS MUCH OF THE SHORT TERM GUIDANCE HAS
CONDITIONS DRY NOW AND CONTINUES THIS TREND THROUGH THE DAY. LEANED
ON PERSISTENCE FOR THE FORECAST TODAY AND TONIGHT. MOS BLEND YIELDS
HIGHS IN THE UPPER 60S TO MID 70S SEEMS REASONABLE.

&&

.SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/...

ISSUED AT 327 AM EDT WED APR 17 2013

THE AFOREMENTIONED STALLED FRONTAL BOUNDARY NEAR THE OHIO RIVER WILL
LIFT NORTHWARD AS A WARM FRONT TONIGHT...GENERATING RENEWED CHANCES
FOR SHOWERS AND THUNDERSTORMS. BEST MOISTURE...LIFT...AND
INSTABILITY LIES MAINLY NORTH OF I-70 AND THIS IS WHERE THE HIGHER
POPS ARE CONCENTRATED FOR TONIGHT. WENT A FEW DEGREES ABOVE MOS FOR
LOWS AVERAGING THE MID 60S.

CENTRAL INDIANA WILL BE FIRMLY IN THE WARM SECTOR THURSDAY. WITH
STRONG SW LLVL FLOW HIGH TEMPERATURES WILL BE CLOSER TO THE MAVMOS
THAN MET...DESPITE THE CLOUD COVER AND PRECIP CHANCES. LOOK FOR
HIGHS IN THE UPPER 70S (N) TO LOW 80S (S). AGREE WITH PREVIOUS
THINKING THAT THERE REALLY IS NOT MUCH OF A FORCING MECHANISM FOR
WIDESPREAD CONVECTION DURING THE DAY THURSDAY...OTHER THAN SOME LEFT
OVER RESIDUAL BOUNDARIES FROM NIGHT BEFORE OR DIURNALLY CHARGED.
KEPT POPS AT CHANCE...EXCEPT FOR THE FAR NW LATER IN THE DAY AS THE
FRONT QUICKLY APPROACHED THE REGION.

COLD FRONT EXPECTED TO MOVE THROUGH THE AREA LATE THURSDAY
NIGHT/EARLY FRIDAY MORNING. FORCING ALONG THE FRONT LOOKS
STRONG...ALONG WITH STRONG DEEP LAYER SHEAR...ALTHOUGH THE LAPSE
RATES LOOK RATHER POOR AT THIS POINT. NEVERTHELESS...HIGH WINDS ARE
POSSIBLE GIVEN THE EXPECTED WIND FIELDS/LIFT. 80-90 POPS DURING THIS
PERIOD WILL CONTINUE AT THIS TIME...ALONG WITH A SLIGHT RISK FOR
SEVERE WX FOR THE ENTIRE FORECAST AREA.

WILL KEEP SOME POPS GOING FOR FRIDAY AS WELL TO COVER ANY LINGERING
ACTIVITY IN THE WAKE OF FRONT. AREA SHOULD BE DRY BY FRIDAY NIGHT.

&&

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

ISSUED AT 327 AM EDT WED APR 17 2013

IN WAKE OF THE COLD FRONT AT THE END OF THE WORK WEEK...AN AREA OF
COLD HIGH PRESSURE BUILDS INTO THE OHIO VALLEY FROM THE NORTHWEST.
THIS WILL KEEP DRY BUT COOL CONDITIONS ACROSS CENTRAL
INDIANA...WITH BELOW NORMAL TEMPERATURES. LOWS ON SATURDAY MORNING
WILL NEED TO BE WATCHED AS FROST POTENTIAL MAY EXIST...HOWEVER THE PRESSURE
GRADIENT AT THAT TIME STILL SUGGESTS THAT WINDS BE STRONG ENOUGH
TO PREVENT FROST FORMATION AND SKIES MAY REMAIN PARTLY CLOUDY. HIGH
PRESSURE SHIFTS EAST OF INDIANA THROUGH THE WEEKEND AND INTO THE
NEXT WORKWEEK. A RETURN OF SOUTHERLY FLOW AROUND THE HIGH SHOULD
RESULT IN SLIGHTLY WARMER TEMPERATURES EACH DAY. THE NEXT BEST
CHANCE FOR PRECIP APPEARS ON TUESDAY AND TUESDAY NIGHT AS A STRONG
COLD FRONT ONCE AGAIN PUSHES THROUGH THE STATE.

&&

.AVIATION /DISCUSSION FOR THE 160600Z TAFS/...

ISSUED AT 1233 AM EDT WED APR 17 2013

FRONTAL BOUNDARY IS CURRENTLY DOWN NEAR THE OHIO RIVER...BUT A
PERSISTENT LOW LEVEL JET WILL REMAIN ACROSS THE REGION OVER THE NEXT
SEVERAL HOURS. THIS WILL COMBINE WITH INCREASING ISENTROPIC LIFT AND
WARM ADVECTION TO MAINTAIN SCATTERED CONVECTION ACROSS THE FORECAST
AREA FOR THE NEXT SEVERAL HOURS. WILL CONTINUE TO CARRY TEMPO GROUPS
FOR THUNDER THROUGH 09Z. THE AXIS OF STRONGEST LIFT SHOULD LIFT
NORTH TOWARDS DAYBREAK...WITH CONVECTIVE COVERAGE DIMINISHING INTO
THE MORNING. MODEL SOUNDINGS INDICATING DEEP MOISTURE TRAPPED
BENEATH A SHARP INVERSION...AND ANTICIPATE WIDESPREAD IFR CEILINGS
AND LOWER TO IMPACT THE TERMINALS THROUGH LATE MORNING. CEILINGS
WILL BEGIN TO LIFT INTO THE AFTERNOON AS THE INVERSION WEAKENS.
LIKELY TO SEE SCATTERED CONVECTION DEVELOP ONCE AGAIN DURING THE
AFTERNOON AS THE FRONT LIFTS BACK NORTH THROUGH THE REGION. WILL
CONTINUE TO CARRY A PERIOD OF VCTS DURING THE LATE AFTERNOON AND
EARLY EVENING. WINDS WILL GRADUALLY VEER FROM EAST-NORTHEAST EARLY
THIS MORNING TO SOUTHEAST THROUGH THE DAY AT ABOUT 10KTS.

&&

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