AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
1233 AM EDT WED APR 17 2013

.UPDATE...

THE AVIATION SECTION HAS BEEN UPDATED BELOW.

&&

.SYNOPSIS...
ISSUED AT 232 PM EDT TUE APR 16 2013

A FRONTAL SYSTEM LOCATED NEAR THE OHIO RIVER IS EXPECTED TO MOVE
NORTH ACROSS THE FORECAST AREA WEDNESDAY NIGHT. 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 /OVERNIGHT/...
ISSUED AT 1005 PM EDT TUE APR 16 2013

FRONTAL BOUNDARY HAS SHIFTED TO JUST SOUTH OF THE OHIO RIVER AS OF
02Z. DESPITE THAT...SCATTERED CONVECTION CONTINUES TO DEVELOP AND
MOVE ACROSS SOUTHERN PORTIONS OF THE FORECAST AREA...AND
ADDITIONAL STORMS HAVE DEVELOPED INTO THE NORTHERN WABASH VALLEY.
TEMPS AS OF 02Z HAD FALLEN INTO THE UPPER 40S AND LOWER/MID 50S NORTH
OF THE BOUNDARY.

MESOANALYSIS INDICATING INSTABILITY GRADIENT REMAINS NORTH OF THE
BOUNDARY AND DRAPED OVER FAR SOUTHERN COUNTIES...LIKELY
CONTRIBUTING TO THE PERSISTENCE OF STORMS. LOW LEVEL JET REMAINS
ACROSS THE REGION AND INCREASING WARM ADVECTION AND ISENTROPIC
UPGLIDE LIKELY CONTRIBUTING TO THE NOTED INCREASE IN CONVECTION
OVER THE LAST TWO HOURS. PRESENCE OF THE DEEPER LIFT AND WARM
ADVECTION SHOULD ENABLE CONVECTION TO PERSIST FOR THE NEXT SEVERAL
HOURS AS THE FRONT BECOMES STATIONARY JUST SOUTH OF THE OHIO
RIVER. WILL MAINTAIN SCATTERED THUNDERSTORMS ALL NIGHT 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. STORMS OVER FAR SOUTHERN COUNTIES IN CLOSEST
PROXIMITY TO THE BOUNDARY MAY CONTINUE TO POSE A RISK FOR HAIL
WITH ELEVATED CORES FOR THE NEXT COUPLE HOURS...OTHERWISE STORMS
WILL REMAIN BELOW SEVERE LEVELS. TEMPS ARE CURRENTLY AT THEIR MINS
FOR THE NIGHT...EXPECT TEMPS TO REMAIN STEADY OR SLOWLY RISE
OVERNIGHT.

ZONE AND GRID UPDATES OUT.

&&

.SHORT TERM /WEDNESDAY THROUGH FRIDAY/...
ISSUED AT 232 PM EDT TUE APR 16 2013

MODEL DATA SUGGEST FRONT WILL PRETTY MUCH HOLD ITS POSITION NEAR THE
OHIO RIVER INTO WEDNESDAY NIGHT. A DEVELOPING STRONG LOW LEVEL JET
AHEAD OF APPROACHING PLAINS SYSTEM SHOULD SERVE TO PUSH THIS FRONT
BACK TO THE NORTH WEDNESDAY NIGHT. WILL CONTINUE WITH CHANCE POPS
FOR WEDNESDAY...AND GO WITH LIKELY POPS OVER MOST OF THE
AREA...EXCEPT FOR THE SOUTHEAST...WEDNESDAY NIGHT AS THERE SHOULD BE
GOOD FORCING ALONG THE JET.

SHOULD BE IN THE WARN SECTOR THURSDAY. OTHER THAT
INSTABILITY...DON/T SEE ANY REAL FOCUS FOR CONVECTION AT THAT
TIME...OTHER THAN POSSIBLY SOME RESIDUAL BOUNDARIES FROM THE
WEDNESDAY NIGHT ACTIVITY. WILL KEEP POPS IN THE CHANCE CATEGORY AT
THAT TIME.

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. WILL GO WITH HIGH POPS
THURSDAY NIGHT.

WILL KEEP SOME POPS GOING FOR FRIDAY AS WELL TO COVER ANY LINGERING
ACTIVITY IN THE WAKE OF FRONT.

PROGGED LOW LEVEL THICKNESSES SUGGEST THE GFS MOS HIGHS FOR
WEDNESDAY AND THURSDAY MAY STILL BE A LITTLE WARM...ESPECIALLY IN
THE SOUTH. WILL NUDGE THE GUIDANCE DOWN A LITTLE IN THOSE AREAS.
LOWS DON/T LOOK TOO BAD.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
ISSUED AT 232 PM EDT TUE APR 16 2013

ECMWF AND GFS DEPICT THE DEPARTURE OF A STRONG COLD FRONT ON FRIDAY
AS ANOTHER 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 BODE WATCHING AS FROST POTENTIAL MAY EXIST...HOWEVER
PRESSURE GRADIENT AT THAT TIME STILL SUGGESTS THAT WINDS BE STRONG
ENOUGH TO PREVENT FROST FORMATION. WILL WATCH CLOSELY.

AS HIGH PRESSURE SHIFTS EAST OF INDIANA THROUGH THE WEEKEND AND INTO
THE NEXT WORKWEEK...RETURN SOUTHERLY FLOW AROUND THE HIGH SHOULD
RESULT IN SLIGHTLY WARMER TEMPERATURES EACH DAY.

THE NEXT BEST CHANCE FOR PRECIP APPEARS ON TUESDAY AS A STRONG COLD
FRONT ONCE AGAIN PUSHES THROUGH THE STATE.

&&

.AVIATION /DISCUSSION FOR THE 16/06Z 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.
