AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
1215 PM EDT WED SEP 10 2014

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

&&

.SYNOPSIS...
ISSUED AT 330 AM EDT WED SEP 10 2014

A COLD FRONT ASSOCIATED WITH A RATHER STRONG FRONTAL SYSTEM WILL
MOVE ACROSS CENTRAL INDIANA TODAY AND TONIGHT BRINGING HEAVY
RAINFALL AND POSSIBLE SEVERE WEATHER. MUCH COOLER WEATHER WILL
FOLLOW IN ITS WAKE ALONG WITH SOME DRIER WEATHER ON THURSDAY NIGHT
AND FRIDAY. HOWEVER...PRECIP CHANCES WILL RETURN AGAIN ON FRIDAY
NIGHT WITH THE PASSAGE OF AN UPPER LOW OVER THE GREAT LAKES REGION.

&&

.NEAR TERM /REST OF TODAY/...
ISSUED AT 950 AM EDT WED SEP 10 2014

FORECAST IS ON TRACK. ADJUSTED POPS UP THIS MORNING ACROSS THE NORTH
BASED ON CURRENT RADAR TRENDS. EXPECT ADDITIONAL STORMS TO DEVELOP
THIS AFTERNOON AHEAD OF THE COLD FRONT.

CENTRAL INDIANA REMAINS IN A SLIGHT RISK FOR SEVERE WEATHER. WILL
CONTINUE TO MONITOR CLOSELY. THREAT FOR HEAVY RAIN STILL EXISTS WITH
PRECIPITABLE WATER VALUES OVER 2 INCHES MOVING INTO THE AREA.

NUDGED DOWN TEMPERATURES A BIT ACROSS PORTIONS OF THE AREA SINCE
RAIN THIS MORNING WILL KEEP READINGS DOWN FOR A WHILE.

PREVIOUS DISCUSSION FOLLOWS...
THE MAIN FOCUS OF THE NEAR TERM PERIOD IS FLOODING AND SEVERE
POTENTIAL WITH COLD FRONT.

RAPID REFRESH IS PORTRAYING CURRENT RADAR ACTIVITY
WELL...WIDESPREAD SHOWERS WITH EMBEDDED THUNDERSTORMS CURRENTLY
MOVING ACROSS ILLINOIS AHEAD OF FRONTAL SYSTEM CENTERED OVER IOWA.
THIS ACTIVITY WILL SPREAD ACROSS CENTRAL INDIANA THIS MORNING WITH
ENVIRONMENT GRADUALLY DESTABILIZING THIS AFTERNOON. DEWPOINTS ARE
PROGGED TO CLIMB INTO THE LOW 70S WITH MLCAPES IN THE 1000 TO 2000
J/KG RANGE. AS COLD FRONT MOVES INTO THIS ENVIRONMENT LATE THIS
AFTERNOON/EVENING...SEVERE THUNDERSTORMS COULD DEVELOP AHEAD AND
ALONG THE LINE WITH DAMAGING WINDS. THERE IS SOME QUESTION AS TO HOW
LONG THOSE STORMS WILL MAINTAIN THEIR STRENGTH THE FARTHER SOUTH
THEY MOVE AND AS THEY LOSE THE DAYTIME HEATING. THE BEST DYNAMICS
STILL REMAIN OVER LOWER MICHIGAN/NORTHERN INDIANA WHERE A 50 TO 60
KT LOW LEVEL JET AND 80 TO 100 KT 300 MB JET WILL PROVIDE
ADDITIONAL ENHANCEMENT.

THE LARGER THREAT TO CENTRAL INDIANA WILL MOST LIKELY BE THE
FLOODING THREAT WITH QPFS STILL AT 2 PLUS INCHES. SO...WILL
CONTINUE TO CARRY THE FLASH FLOOD WATCH OVER THE NORTHERN TWO-
THIRDS OF FORECAST AREA.

TEMPS...STUCK CLOSE TO GUIDANCE FOR THIS AFTERNOON...WHICH PUTS
HIGHS IN THE UPPER 70S TO MID 80S. THIS WILL HAVE TO BE MONITORED
THOUGH...ANY LINGERING CLOUD COVER COULD MAKE IT TOUGH TO REACH
THOSE NUMBERS.

&&

.SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/...
ISSUED AT 330 AM EDT WED SEP 10 2014

AS MENTIONED ABOVE...THERE IS DOUBT AS TO HOW LONG LINE OF STORMS
WILL MAINTAIN THEIR INTENSITY THROUGH THE LATE EVENING/EARLY NIGHT
HOURS WITH LOSS OF HEATING AND LIFT. THE BULK OF THE ACTIVITY WILL
BE SITUATED OVER SOUTHEAST INDIANA DURING THAT TIME...AND OUT OF
THE AREA BY THU 12Z.

MOST OF THURSDAY AND FRIDAY WILL BE DRY WITH COOLER TEMPS. HIGHS
WILL ONLY TOP OFF IN THE UPPER 60S/LOW 70S ON BOTH DAYS. MODELS
HAVE A GOOD HANDLE ON THE CHANGING PATTERN...SO WENT WITH
ALLBLEND.

FRIDAY NIGHT...INTRODUCED PRECIP BACK INTO THE FORECAST AS AN
UPPER LEVEL LOW MOVES ACROSS THE GREAT LAKES REGION. BEST FORCING
WILL BE OVER THE NORTHERN PORTIONS OF CENTRAL INDIANA...SO CARRIED
CHANCE POPS OVER THOSE COUNTIES...AND SLIGHT CHANCE POPS
ELSEWHERE.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
ISSUED AT 330 AM EDT WED SEP 10 2014

HIGH PRESSURE AND A PERSISTENT UPPER TROUGH OVER THE EASTERN U S
WILL MAINTAIN A COOL...MAINLY DRY WEATHER PATTERN OVER THE REGION
THROUGH THE EXTENDED PERIOD.

SOME LINGERING CLOUDS SATURDAY MORNING IN THE WAKE OF THE WAVE ALOFT
WILL DIMINISH QUICKLY DURING THE COURSE OF THE DAY AS BROAD HIGH
PRESSURE BUILDS INTO THE OHIO VALLEY AND GREAT LAKES. THE HIGH WILL
DRIFT EAST OF THE REGION BY MONDAY WITH A SECONDARY WAVE ALOFT IN
THE NORTHERN STREAM ROTATING INTO THE GREAT LAKES BY MONDAY EVENING.
OVERALL MOISTURE PROFILES LOOK UNIMPRESSIVE...BUT FORCING ALOFT
ASSOCIATED WITH THE FEATURE MAY BE JUST ENOUGH TO GENERATE A FEW
SHOWERS OVER THE NORTHERN HALF OF THE FORECAST AREA MONDAY NIGHT.
HIGH PRESSURE WILL THEN REESTABLISH THROUGH THE MIDDLE OF NEXT WEEK.

HIGHS WILL BE IN THE 60S OVER THE WEEKEND...RISING INTO LOWER AND
MIDDLE 70S BY EARLY NEXT WEEK. A FEW CHILLY MORNINGS ANTICIPATED
WITH LOWS IN THE 40S THROUGH MONDAY MORNING...WARMING INTO THE LOWER
50S NEXT WEEK.

&&

.AVIATION /DISCUSSION FOR 101800Z TAF ISSUANCE/...
ISSUED AT 1215 PM EDT WED SEP 10 2014

WIDESPREAD THUNDERSTORMS ARE EXPECTED THIS AFTERNOON AHEAD OF A
STRONG COLD FRONT FROM NEAR KIRK TO KOKC EARLY THIS AFTERNOON.
SO...WILL HAVE TEMPO MVFR OR WORSE THUNDERSTORM GROUPS IN THROUGH
00Z AT LAF AND A LITTLE LATE ELSEWHERE AS THE FRONT SETTTLES
SOUTHEAST. THE FRONT SHOULD REACH LAF AROUND 03Z OR SO AND A FEW
HOURS LATER AT BMG. WINDS WILL BE SOUTH AND SOUTHEAST 15 KNOTS OR
MORE AND GUSTING TO NEAR 25 KNOTS. GUSTS TO 40 KNOTS OR MORE ARE
POSSIBLE IN THUNDERSTORMS. WINDS WILL BECOME NORTHWEST BEHIND THE
COLD FRONT. EXPECT IFR CEILINGS OVERNIGHT AND INTO THURSDAY MORNING.
