AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
150 PM EDT THU AUG 16 2012

.UPDATE...

THE LONG TERM SECTION HAS BEEN UPDATED BELOW.

&&

.SYNOPSIS...
ISSUED AT 230 PM EDT THU AUG 16 2012

A COLD FRONT WILL DROP SOUTHEAST ACROSS CENTRAL INDIANA TONIGHT
RESULTING IN SCATTERED TO NUMEROUS THUNDERSTORMS...SOME OF WHICH
COULD BE SEVERE WITH DAMAGING WINDS AND LARGE HAIL POSSIBLE.
THEN...HIGH PRESSURE WILL BUILD IN...IN THE WAKE OF THE FRONT WHICH
WILL RESULT IN COOL AND DRY WEATHER THROUGH EARLY NEXT WEEK.
FINALLY...TEMPERATURES ARE EXPECTED TO MODERATE AND BECOME NEAR
NORMAL BY THE MIDDLE OF NEXT WEEK.

&&

.NEAR TERM /TONIGHT/...
ISSUED AT 141 PM EDT THU AUG 16 2012

THE MAIN FOCUS ON THE NEAR TERM WILL BE ON THUNDERSTORM COVERAGE
INCLUDING SEVERE POTENTIAL ALONG WITH COLD FRONTAL TIMING.

EARLY THIS AFTERNOON...SURFACE ANALYSIS WAS SHOWING A COLD FRONT
ACROSS NORTHERN ILLINOIS SOUTHWEST TO NORTHWEST ARKANSAS. THE FRONT
WAS MAKING DECENT PROGRESS SOUTHEAST WITH FAST NORTHWEST FLOW AROUND
THE BASE OF AN UPPER LOW ACROSS ONTARIO. AHEAD OF THE FRONT...RADAR
WAS SHOWING A LINE OF STRONG THUNDERSTORMS FROM NORTHEAST INDIANA
AND SOUTHWEST ACROSS OUR CENTRAL COUNTIES. MEANWHILE...THERE WAS A
LARGE AREA OF SHOWERS AND EMBEDDED THUNDERSTORMS BEHIND THE MAIN
SQUALL LINE...AND ADDITIONAL ACTIVITY FIRING UP ACROSS NORTHERN
ILLINOIS NEAR THE FRONT.

THE 12Z NAM HAS NOW CAUGHT ON WITH THE CONSISTANT GFS AND ECMWF
REGARDING THE QUICKER FRONTAL SPEED. MODEL BLEND HAS THE COLD FRONT
TO OUR FAR NORTHWEST COUNTIES BY 00Z THIS EVENING AND SOUTH OF THE
AREA AROUND 09Z. ALONG AND AHEAD OF THE FRONT...RAPID REFRESH
REFLECTIVITY FORECAST...RADAR TRENDS...MODEL INSTABILITY PROGS AND
OVERALL SYSTEM DYNAMICS...SUGGEST LIKELY TO CATEGORICAL POPS TONIGHT
TAPPERING OFF TO CHANCE AFTER 06Z NORTHWEST.

INSTABILITY PROGS ARE SHOWING 2000 J/KG OR MORE POOLED IN THE
VICINITY OF THE COLD FRONT 00Z THIS EVENING...WHILE MODEL TIME
SECTIONS ARE SHOWING DEEP MOISTUE IN THE COLUMN. MODELS ALSO SHOW
STRONG ELONGATED UPPER VERTICAL MOTION FIELDS AND...ALONG WITH RADAR
TRENDS AND RAPID REFRESH...SUGGEST SEVERAL LINES OF STORMS LIKELY IN
THE VICINITY AND AHEAD OF THE FRONT. CENTRAL INDIANA WILL ALSO BE
WITHIN DECENT 25 KNOT OR MORE LOW LEVEL FLOW AND BE IN THE RIGHT
REAR QUADRANT OF A 90 PLUS UPPER LEVEL JET ACROSS THE GREAT LAKES.
THUS...SPC DAY 1 SLIGHT RISK FOR DAMAGING WINDS AND LARGE HAIL
CERTAINLY IS WARRANTED.

MOS TEMPERATURES ARE IN SURPRISINGLY DECENT AGREEMENT CONSIDERING A
FRONT THIS STRONG....SO WILL GO WITH A BLEND.

&&

.SHORT TERM /FRIDAY THROUGH SUNDAY/...
ISSUED AT 141 PM EDT THU AUG 16 2012

THE MAIN CHALLENGE TO THE SHORT TERM WILL BE WHETHER OR NOT TO HOLD
ON MORNING POPS FRIDAY AS WELL AS CLOUD COVER AND TEMPERATURES.
THEN...THE FOCUS WILL SHIFT TO TEMPERATURES AS COOL CANADIAN HIGH
PRESSURE BUILDS IN BEHIND THE DEPARTING COLD FRONT.

THE 12Z NAM IS NOW FASTER AND VERY NEAR THE GFS AND ECWMF REGARDING
THE FRONTAL POSITION AT 12Z FRIDAY. SO...A MODEL BLEND LOOKS GOOD.
MODELS HAVE THE FRONT ACROSS NORTH CENTRAL KENTUCKY BY 12Z FRIDAY
WITH DEEPER MOISTURE AND LIFT SOUTH OF SOUTH CENTRAL INDIANA.
THUS...SEE NO REASON TO KEEP EVEN A SMALL CHANCE OF MORNING SHOWERS
ACROSS OUR FAR SOUTH. HOWEVER...WITH MODEL TIME SECTIONS AGREEING ON
LINGERING POST-FRONTAL LOW LEVEL MOISTURE AND CYLCONIC FLOW ALOFT ON
THE SOUTH SIDE OF THE ONTARIO UPPER LOW...SHOULD SEE A DECENT AMOUNT
OF DIURNAL AFTERNOON CU. WITH TIME SECTIONS SHOWING THE REST OF THE
COLUMN DRY...SHOULD SEE SOME SUNSHINE...HOWEVER. PREFER THE COOLER
GFS AND ECMWF 850 TEMPERATURES WITH THE STRENGTH OF THIS SYSTEM.
THIS WOULD FAVOR THE COOLER GFS MOS TEMPERATURES WHICH HAVE BEEN
PREFERED ALL ALONG.

FOR THE REST OF THE WEEKEND...MODELS IN GOOD AGREEMENT ON BROAD AREA
OF AFOREMENTIONED HIGH PRESSURE ACROSS THE MIDWEST AND LOWER GREAT
LAKES THROUGH SUNDAY. IN ADDITION...MODEL TIME SECTIONS WERE SHOWING
LOW LEVEL DRYING AND WERE HINTING AT MOSLT ONLY CIRRUS THROUGH THE
WEEKEND IN THE PERSISTANT UPPER CYCLONIC FLOW.

MODEL 850 MILLIBAR TEMPERATURES CHANGE LITTLE THIS WEEKEND AND ARE
PRETTY CLOSE...SO A MOS BLEND LOOKS JUST FINE WITH AFTERNOON HIGHS
MOSTLY IN THE 70S EXCEPT FOR PERHAPS FAR SOUTH WHERE HIGHS COULD
REACH 80. OVERNIGHT LOWS WILL ONLY BE IN THE 50S.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
ISSUED AT 141 PM EDT THU AUG 16 2012

GUIDANCE IS IN GENERAL AGREEMENT ON A RELATIVELY DRY AND COOL LONG
TERM PERIOD...WITH UPPER LEVEL CYCLONIC FLOW ACROSS THE GREAT
LAKES AND BROAD HIGH PRESSURE IN CONTROL AT THE SURFACE. ALLBLEND
TRENDS BACK TOWARDS CLIMATOLOGY WITH TIME...WHICH IS REASONABLE AS
FLOW BECOMES MUCH LESS AMPLIFIED AS THE PERIOD WEARS ON.

LITTLE OPPORTUNITY TO IMPROVE ON INITITIALIZATION TEMPS AS THEY
ARE REASONABLE IN LIGHT OF 850 TEMPS BEGINNING THE PERIOD 10-12C
AND RISING TO 16C BY LATE IN THE WEEK. GRADUAL WARMING TREND IS
DEPICTED WELL.

&&

.AVIATION /DISCUSSION FOR THE 16/18Z TAFS/...
ISSUED AT 1230 PM EDT THU AUG 16 2012

MAINLY VFR THROUGH THE PERIOD OUTSIDE OF ANY THUNDERSTORMS.

INITIAL COMPLEX OF STORMS NOW PASSING THROUGH NORTHERN HALF OF THE
AREA...LIKELY ONLY BRUSHING HUF AND ONLY APPROACHING VICINITY
BMG...WITH A LULL BEFORE ADDITIONAL DEVELOPMENT IMPACTS THE AREA AS
THE FRONT APPROACHES LATER IN THE AFTERNOON/EVENING. HAVE ATTEMPTED
TO TIME BEST OPPORTUNITY FOR ADDITIONAL STORMS WITH TEMPO GROUPS
LATER THIS EVENING PRIOR TO FRONTAL PASSAGE.

MAV/LAMP WANTS TO DEVELOP POST FRONTAL STRATUS LATE TONIGHT INTO
EARLY TOMORROW...BUT THIS MAY BE AN ARTIFACT OF ITS LONG STANDING
STRUGGLES WITH LOW LEVEL MOISTURE FIELDS. WILL HINT AT THIS FOR NOW
WITH A SCT015 DECK OVERNIGHT...AND LEAVE TO LATER PACKAGES TO
EVALUATE.
