AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
104 PM EDT FRI SEP 7 2012

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

&&

.SYNOPSIS...

ISSUED AT 335 AM EDT FRI SEP 7 2012

A STRONG UPPER TROUGH OVER THE UPPER MIDWEST WILL ROTATE ACROSS OUR
REGION BY SATURDAY.  THIS WILL CAUSE A COLD FRONT FROM THE CENTRAL
PLAINS TO WISCONSIN TO STRENGTHEN AS IT MOVES OUR WAY BY TONIGHT.
MODELS ALSO DEVELOP A LOW PRESSURE SYSTEM ALONG THE FRONT...AND MOVE
IT ACROSS OUR REGION EARLY TONIGHT AND INTO THE EASTERN GREAT LAKES
ON SATURDAY.  THIS FRONTAL SYSTEM WILL BRING LOCALLY HEAVY RAINFALL
LATER TONIGHT AND EARLY TONIGHT.  A FEW SHOWERS COULD LINGER INTO
SATURDAY MORNING. OTHERWISE...MUCH COOLER AND DRY WEATHER WILL BE
THE RULE THE REST OF THE WEEKEND.

IN THE EXTENDED AN UPPER TROUGH OVER THE ST. LAWRENCE RIVER MOVES ON
TO THE EAST AND WARMER AND DRY WEATHER WILL BE THE RULE AS HIGH
PRESSURE DOMINATES OUR WEATHER AND AN UPPER RIDGE OVER THE CENTRAL
U.S. BUILDS OUR WAY.

&&

.NEAR TERM /THIS AFTERNOON/...

ISSUED AT 1226 PM EDT FRI SEP 7 2012

1615Z UPDATE...CONVECTIVE OUTFLOW HAS GENERALLY SURGED S OF THE
REMNANT MCS ACROSS CNTRL IL. AS SURFACE HEATING CONTINUES
DOWNSTREAM ACROSS THE CWA AND WITH CONVECTIVE TEMPERATURES IN THE
80S...ONGOING ACTIVITY WILL BECOME SURFACE-BASED. AMIDST
FAVORABLE 0-6 KM SPEED SHEAR AS SAMPLED BY THE WOLCOTT IND
PROFILER...CONVECTION WILL INTENSIFY AND LIKELY DEVELOP EMBEDDED
SHORT-LINE SEGMENTS CAPABLE OF PRODUCING DAMAGING WINDS. THEREFORE
SEVERE THUNDERSTORM WATCH 628 FOR THE NORTHERN HALF THE CWA WAS
ISSUED AROUND 1130 AM.

PREVIOUS DISCUSSION FOLLOWS...

1015Z UPDATE...WELL UNLIKE YESTERDAY THERE REMAINS QUITE A BIT OF
UNCERTAINTY WITH REGARD TO THE MODEL TIMING OF THIS SYSTEM. THE
GENERAL CONSENSUS IS THAT THE TIMING HAS SLOWED DOWN
CONSIDERABLY...BY AS MUCH AS 6 HOURS COMPARED TO THIS TIME
YESTERDAY...PUSHING THE BULK OF THE SHOWER/TSRA ACTIVITY UNTIL
LATER THIS EVENING...CLOSER TO 00Z.

IN THE MEANTIME...A COMPLEX OF STORMS DEVELOPED OVER PORTIONS OF
IOWA LAST NIGHT AND AND IS CURRENTLY OVER NE IL AND NW IN. SHORT
TERM GUIDANCE SHOWS THIS ACTIVITY BEING KEPT TO THE NORTH OF THE
AREA...BUT RADAR TRENDS ARE LEADING TO BELIEVE SOME OF THIS WILL
MAKE IT INTO OUR NW/W COUNTIES BY THIS AFTERNOON. HAVE ACCOUNTED
FOR THIS IN THE GRIDS.

IN TERMS OF OTHER GRID COMPONENTS...MADE SOME ADJUSTMENTS TO
SKY/TEMP/DEW PT...MAINLY TO ACCOUNT FOR LATEST TRENDS. PREVIOUS
DISCUSSION FOLLOWS...

THUNDERSTORMS WERE CURRENTLY DEVELOPING ACROSS IOWA...AND PARTS OF
THE CENTRAL PLAINS.  MODELS DISAGREE ON HOW FAST THUNDERSTORMS MOVE
INTO OUR REGION AND THIS COULD HAVE A BIG AFFECT ON TEMPERATURES.
THE GFS AND GEMNH BRING PRECIP QUICKLY INTO OUR REGION...WHILE THE
NAM...MM5 AND RAPID REFRESH MOVE THE IOWA STORMS INTO NORTHERN
INDIANA LATER THIS MORNING AND DON'T BRING MUCH INTO OUR REGION
UNTIL AFTER 21Z.  AS A RESULT WILL GO A LITTLE WARMER MOST AREAS
TODAY AND WILL ONLY KEEP MENTION OF HEAVY RAINFALL ACROSS OUR
NORTHWEST THIS AFTERNOON. WILL MENTION CHANCE POPS ACROSS OUR
NORTHWEST HALF BY LATE MORNING AND HIGH POPS ACROSS OUR NORTHWEST
2/3 BY LATE AFTERNOON WITH CHANCE POPS IN THE SOUTHEAST.

SPC HAS US UNDER A SLIGHT RISK OF SEVERE STORMS THIS AFTERNOON AND
EARLY TONIGHT.  NAM INDICATES MU CAPES OF UP TO 3500 J/KG AND
MODERATE LOW LEVEL SHEAR.

&&

.SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...

ISSUED AT 335 AM EDT FRI SEP 7 2012

FORECAST FOCUS WILL BE ON RAIN AMOUNTS AND CHANCES TONIGHT AS WELL
AS THREAT FOR SEVERE WEATHER.  ALL MODELS INDICATE LOCALLY HEAVY
RAINFALL THIS EVENING WITH SOME AREAS RECEIVING 1 TO 2 INCHES OF
PRECIP AS A COLD FRONT MOVES THROUGH AHEAD OF THE ROTATING UPPER
TROUGH.  MOST OF THE SEVERE WEATHER AND HEAVY RAINFALL WILL BE IN
THE EVENING...THEN PRECIP WILL LESSEN OVERNIGHT AFTER COLD FRONT
MOVES THROUGH.  WILL MENTION SLIGHT CHANCE POPS ACROSS OUR EAST
EARLY SATURDAY PER SREF. WIND GUSTS OF 20 TO 25 KNOTS WILL BE
POSSIBLE SATURDAY AS A PRETTY GOOD PRESSURE GRADIENT WILL BE ACROSS
OUR REGION.

DRY AND COOL WEATHER WILL BE THE RULE DURING REST OF THE SHORT TERM
AS HIGH PRESSURE BUILDS INTO THE NORTHERN PLAINS SATURDAY AND INTO
OUR REGION SUNDAY AND SUNDAY NIGHT.  WILL MENTION CLEARING SKIES
SATURDAY NIGHT AND MOSTLY CLEAR AND COOL WEATHER SUNDAY.

AS FAR AS TEMPERATURES ARE CONCERNED...WENT CLOSE TO A MAV/MET BLEND
MOST AREAS.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...

ISSUED AT 335 AM EDT FRI SEP 7 2012

MODELS ARE IN DECENT AGREEMENT THROUGH THE LONG TERM...SO THE
ALLBLEND INITIALIZATION WAS ACCEPTED.

AN UPPER RIDGE WILL BUILD IN ALOFT DURING THE PERIOD WITH HIGH
PRESSURE AT THE SURFACE. THIS WILL KEEP THE LONG TERM DRY AND ALLOW
FOR GRADUALLY WARMING TEMPERATURES THROUGH THE PERIOD. TEMPERATURES
WILL START OUT BELOW AVERAGE BUT WARM TO ABOVE AVERAGE BY THE END OF
THE PERIOD.

&&

.AVIATION /DISCUSSION FOR THE 071800Z TAFS/...
ISSUED AT 1256 PM EDT FRI SEP 7 2012

CONVECTION OVER EAST CENTRAL ILLINOIS IS EXPECTED TO PROPAGATE
EAST ACROSS THE TAF SITES DURING THE FIRST 6 HOURS OF THE TAF
PERIOD. WHEN ANY TSRA STRIKES A TAF SITE MVFR CONDITIONS CAN BE
EXPECTED ALONG WITH BRIEF IFR CONDITIONS POSSIBLE.

AS THE CONVECTION WANES AFTER SUNDOWN...A STRONG COLD FRONT IS
EXPECTED TO PUSH THROUGH THE AREA. CONFIDENCE FOR TSRA WILL BE LOW
AT THIS POINT DUE TO UNCERTAINTY OF THE INSTABILITY DUE TO
PREVIOUS CONVECTION...HOWEVER...WILL CONTINUE TO MENTION VCTS
WITH A TRANSITION TOWARD VCSH IN THE WAKE OF THE FRONT. STRONG
COLD AIR ADVECTION AND TRAPPED STRATOCU WILL LEAD TO SOME MVFR
CIGS AND RECENT RAIN AND COOLING MAY ALSO LEAD TO MVFR FOG
ACROSS THE TAF SITES.

A RETURN TO VFR IS EXPECTED ON SATURDAY MORNING AS HIGH PRESSURE
BUILDS IN ON COOLER NORTHERLY WINDS AND CLOUDS DEPART.

&&

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