AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
1025 PM EDT WED JUN 12 2013

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

&&

.SYNOPSIS...
ISSUED AT 308 PM EDT WED JUN 12 2013

STRONG TO SEVERE STORMS WILL OCCUR TONIGHT AHEAD OF A COLD FRONT.
RAIN WILL LINGER INTO THURSDAY MORNING...THEN DRY CONDITIONS CAN BE
EXPECTED UNTIL SATURDAY AFTERNOON. A COUPLE OF WEATHER SYSTEMS WILL
KEEP CHANCES FOR RAIN AROUND FROM SATURDAY AFTERNOON INTO NEXT
TUESDAY. TEMPERATURES WILL BE COOLER THAN NORMAL ON THURSDAY BUT
RETURN TO NEAR AVERAGE AND REMAIN THERE FROM THE WEEKEND ON.

&&

.NEAR TERM /OVERNIGHT/...

ISSUED AT 926 PM EDT WED JUN 12 2013

GIVEN THE RECENT RADAR TRENDS...MUCH OF THE CONVECTION REMAINS
NORTH OF CENTRAL INDIANA AND CONTINUES TO PROPAGATE EASTWARD. A FEW
CELLS HAVE TRIED TO DEVELOP ON THE SOUTHERN EDGE HOWEVER THEY HAVE
BEEN UNABLE TO SUSTAIN THEMSELVES. MAIN THREAT FROM THE NEXT FEW
HOURS WILL BE WITH THE CLUSTER OF STORMS NEAR KIRKSVILLE
ILLINOIS...AND IT/S PROPAGATION TO THE EAST OR THE SOUTHEAST. THUS
HAVE KEPT POPS HIGHER IN THE LAF...OKK...MUNCIE AND ANDERSON
AREAS...WHILE TRIMMING POPS DRAMATICALLY ACROSS THE FAR SOUTHERN
PARTS OF THE FORECAST AREA. ONGOING TEMPERATURE FORECAST APPEARS
ON THE MARK GIVEN RECENT TRENDS HAVE MADE ONLY MINOR TWEAKS.

&&

.SHORT TERM /THURSDAY THROUGH SATURDAY/...

ISSUED AT 308 PM EDT WED JUN 12 2013

FOCUS IS ON CHANCES FOR RAIN THROUGH THE PERIOD. MODELS ARE CLOSE
ENOUGH THAT A BLEND CAN BE USED.

SOME LINGERING FORCING WILL CONTINUE ACROSS MAINLY THE SOUTHERN AND
EASTERN FORECAST AREA ON THURSDAY MORNING AS SYSTEM EXITS THE AREA.
WENT LIKELY POPS EXTREME EAST TO LOW CHANCE POPS WEST. ENDED CHANCES
FOR RAIN BY AFTERNOON AS THE SYSTEM PULLS EAST.

HIGH PRESSURE WILL THEN PROVIDE DRY CONDITIONS THURSDAY NIGHT INTO
SATURDAY MORNING.

UPPER WAVES RIDING AROUND AN UPPER RIDGE COULD TRIGGER SOME
CONVECTION ACROSS THE AREA SATURDAY AFTERNOON. UNCERTAINTY REMAINS
HIGH IN THE TIMING AND STRENGTH OF THESE WAVES. THEREFORE ONLY WENT
CHANCE POPS SATURDAY AFTERNOON...MAINLY ACROSS THE NORTHWEST
FORECAST AREA CLOSER TO THE FORCING.

FOR TEMPERATURES THROUGH THE PERIOD WENT WITH A BLEND MOST PERIODS.

&&

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

ISSUED AT 227 PM EDT WED JUN 12 2013

MODELS AND WEATHER PREDICTION CENTER SUGGEST A COLD FRONT WILL DROP
SOUTHEAST ACROSS CENTRAL INDIANA ON MONDAY FOLLOWED BY AN UPPER WAVE
ON TUESDAY. MOISTURE STREAMING NORTHEAST OFF THE GULF AHEAD OF THE
FRONT SHOULD ALLOW FOR SCATTERED TO NUMEROUS THUNDERSTORMS PRIOR TO
THE FRONTAL PASSAGE WITH LOWER CHANCES AHEAD OF THE UPPER FEATURE.

REGIONAL INITIALIZATION TEMPERATURES NEAR NORMAL IN THE LOWER TO MID
80S LOOK REASONABLE AND WITH THE SYSTEM TONIGHT TAKING PLENTY OF
FOCUS...WILL NOT MAKE ANY CHANGES.

&&

.AVIATION /DISCUSSION FOR THE 130300Z KIND TAF UPDATE/...
ISSUED AT 1025 PM EDT WED JUN 12 2013

VORTICITY TAIL FROM COMPLEX ACROSS NORTHERN INDIANA CURRENTLY
PUSHING INTO WESTERN INDIANA. SOME CONVECTION HAS BEEN TRYING TO
DEVELOP ALONG THIS TAIL...BUT THIS EVENING/S UPPER AIR SUGGESTS AIR
MASS IS STILL CAPPED TO SOME EXTENT. THIS FEATURE EXPECTED TO PASS
OVER KIND AROUND 130400Z...SO WILL FINE TUNE THE HIGHEST CONVECTIVE
THREAT BETWEEN 130400Z-130600Z. LARGE COMPLEX DROPPING SOUTHEAST MAY
GET CLOSE TO KIND AS WELL AFTER 130400Z. IF THIS COMPLEX REACHES
KIND...GUSTY VARIABLE WINDS TO AROUND 40 KTS POSSIBLE.

PREVIOUS DISCUSSION FOLLOWS.

HIGH CONVECTIVE POTENTIAL ACROSS THE TAF SITES LATER THIS EVENING AS
AN UPPER IMPULSE CURRENTLY ENTERING NORTHWEST ILLINOIS MOVES INTO
NORTHWEST OHIO BY 130600Z. AIR MASS STILL CAPPED OFF...BUT VERY
UNSTABLE. CONVECTION SHOULD RESULT IN EITHER COMPLEX OVER NORTHERN
ILLINOIS TURNING SOUTHEAST...OR DEVELOPMENT ALONG THE TRAILING VORT
TAIL. SHORT TERM MODEL DATA SUGGEST HIGHEST CONVECTIVE POTENTIAL
130100Z-130500Z. BRIEF IFR CONDITIONS...AND GUSTY SHIFTING WINDS IN
THE VICINITY OF THE HEAVIER CELLS.

ADDITIONAL CONVECTION POSSIBLE IN THE WAKE OF THIS WAVE ASSOCIATED
WITH THE COLD FRONT. AT THIS POINT...THINK THE FIRST WAVE WILL SWEEP
OUT MOST OF THE INSTABILITY...BUT IF THIS DOESN/T
HAPPEN...CONVECTIVE THREAT WILL BE HIGHER WITH THE FRONT.

OUTSIDE OF CONVECTION...EXPECTING MVFR CEILINGS TO DEVELOP TOWARDS
SUNRISE THURSDAY IN THE POST FRONTAL ZONE. WILL ALSO KEEP SOME
SURFACE WIND GUSTS AROUND 20 KTS FROM 210-230 DEGREES WELL INTO THE
NIGHT.

834 AM EDT WED JUN 12 2013

THIS HAZARDOUS WEATHER OUTLOOK IS FOR CENTRAL INDIANA.

.DAY ONE...TODAY AND TONIGHT.

OUTLOOK: HOT AND HUMID TODAY. WIDESPREAD THUNDERSTORMS THIS
EVENING AND OVERNIGHT.

HAZARDS: HEAT AND LIGHTNING TODAY. TONIGHT...DAMAGING
WIND...LIGHTNING...LARGE HAIL...ISOLATED TORNADOES AND LOCALIZED
FLASH FLOODING.

TIMING: EVENING INTO THE EARLY OVERNIGHT

DISCUSSION: THE STORM PREDICTION CENTER HAS ISSUED A MODERATE RISK
FORSEVERE WEATHER ACROSS ALL OF CENTRAL INDIANA FOR THIS EVENING
AND EARLY OVERNIGHT. A LINE OF SEVERE THUNDERSTORMS IS EXPECTED
TO FORM ACROSS NORTHWESTERN ILLINOIS LATE THIS AFTERNOON AND EARLY
EVENING AND QUICKLY MOVE EAST AND SOUTHEAST ACROSS CENTRAL INDIANA
THIS EVENING AND INTO THE EARLY OVERNIGHT. A FEW STRONG TO SEVERE
STORMS ARE ALSO POSSIBLE AHEAD OF THE LINE. STRONG WIND SHEAR
ALONG WITH HOT AND HUMID AIR WILL FEED THE STORMS AS A SURFACE AND
UPPER TROUGH HELP MAINTAIN ORGANIZATION.

CONFIDENCE IS HIGH FOR DAMAGING STRAIGHT LINE WINDS IN MANY AREAS.
LARGE HAIL IS ALSO LIKELY BUT SOMEWHAT LESS OF A THREAT. ISOLATED
TORNADOES AND LOCALIZED FLOODING CANNOT BE RULED OUT.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.

OUTLOOK: THUNDERSTORMS ARE EXPECTED AGAIN SATURDAY INTO MONDAY
WITH THE GREATEST THREAT OCCURRING SUNDAY. IT IS TOO EARLY TO
DETERMINE IF THESE STORMS WILL BE SEVERE BUT LIGHTNING IS A HAZARD
IN ALL THUNDERSTORMS.

DISCUSSION: LOW PRESSURE WILL TRACK EAST THROUGH THE GREAT LAKES
THIS WEEKEND AND EARLY NEXT WEEK WITH A FRONTAL BOUNDARY IN THE
AREA. THIS SHOULD HELP TRIGGER MULTIPLE ROUNDS OF THUNDERSTORMS.

.SPOTTER INFORMATION STATEMENT...

SPOTTERS WILL BE NEEDED TONIGHT...AND POSSIBLY AS EARLY AS LATE
AFTERNOON.
