AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
839 AM EST TUE JAN 17 2012

.UPDATE...

THE AVIATION SECTION HAS BEEN UPDATED BELOW.

&&

.SYNOPSIS...

A COLD FRONT IS EXPECTED TO PUSH THROUGH CENTRAL INDIANA THROUGH
THIS MORNING AND DROP TO THE SOUTH OF THE AREA BY THIS AFTERNOON.
IN THE WAKE OF THIS SYSTEM...HIGH PRESSURE IS EXPECTED TO BUILD INTO
THE AREA FOR THE MIDDLE OF THE WEEK. A LOW PRESSURE SYSTEM IS
EXPECTED TO MOVE ACROSS THE GREAT LAKES AROUND THURSDAY. ANOTHER
AREA OF LOW PRESSURE WILL MOVE INTO THE OHIO VALLEY TOWARDS THE END
OF THE WEEK. A COLD FRONT MAY MOVE INTO THE AREA EARLY NEXT WEEK.

&&

.NEAR TERM /TODAY/...

AS OF 230 AM THIS MORNING...SHORT RANGE MODEL DATA AND LATEST
OBSERVATIONS INDICATE THE COLD FRONT WILL BE CLOSE TO THE NORTHWEST
BORDER ZONES BY 171200Z. THIS IS MUCH SLOWER THAN WHAT WAS
ORIGINALLY DEPICTED IN THE MODELS. WIDESPREAD SCATTERED
SHOWERS...AND A FEW EMBEDDED THUNDERSTORMS ARE CURRENTLY OVER THE
FORECAST AREA. MORE WIDESPREAD CONVECTION LIES TO THE SOUTH OF THE
AREA (WHERE BETTER INSTABILITY LIES) AND OFF TO OUR NW AHEAD OF THE
COLD FRONT. THE MORE ORGANIZED LINE OF CONVECTION WILL MOVE ACROSS
CENTRAL INDIANA BETWEEN 11-17Z TODAY...BUT EXPECT ACTIVITY TO WEAKEN
AS IT PUSHES EASTWARD. THE PRE-COLD FRONTAL AIRMASS WILL HAVE
LIMITED MOISTURE CONTENT WITH HEATING/DESTABILIZATION OTHERWISE
LIMITED BY THE PREVALENCE OF CLOUD COVER/SHOWERS TODAY. THIS
LOW-TOPPED CONVECTION WILL TEND TO BE ROOTED JUST ABOVE A
SHALLOW/MARGINALLY MOIST BOUNDARY LAYER. STILL...STRONG
CONVECTIVE WIND GUSTS ARE POSSIBLE...AS IS EVIDENCED
UPSTREAM...WITH GUSTS UP TO 40 TO 50 MPH. WILL MENTION THIS IN THE
HWO ALONG WITH HEAVY RAINFALL AND SMALL HAIL.

TEMPERATURES CONTINUE TO PROVE CHALLENGING...AS OF THIS HOUR THE SW
CORNER OF THE FORECAST AREA HAS WARMED TO NEAR 60 DEGREES! KIND
ITSELF HAS HELD STEADY AT 57 FOR THE LAST FEW HOURS. WITH THE COLD
FRONTAL PASSAGE DELAYED UNTIL LATER TODAY...EXPECT THESE WARM TEMPS
TO REMAIN STEADY THROUGHOUT THE MORNING...AND FINALLY BEGIN TO START
FALLING BY THE AFTERNOON...FIRST BEGINNING ACROSS THE NW.

THE SLOWER TIMING OF THIS FRONT HAS ALSO IMPACTED OUR CHANCES FOR
SNOW OR A RAIN/SNOW MIX THIS AFTERNOON. HELD OFF ON MENTIONING -SN
ACROSS THE NW COUNTIES AND -RAIN/SNOW MIX FOR CENTRAL INDIANA UNTIL
LATE THIS AFTERNOON. (20-21Z TIMEFRAME) MOISTURE WILL BE EXTREMELY
LIMITED BY THEN AND ONLY CHANCES ARE ONLY GOOD FOR 20-40%...SO
SNOWFALL ACCUMULATION WILL BE NIL TO A FEW TENTHS AT MOST.

OF COURSE EVERYTHING IN THIS DISCUSSION HINGES ON THE SPECIFIC
TIMING OF THE FRONTAL PASSAGE AND IS SUBJECT TO UPDATES BASED ON
LATEST TRENDS.

&&

.SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/...

WENT WITH A DRY...AND COOLER FORECAST AFTER 00Z WED AS CAA SWEEPS
OVER THE REGION...EXCEPT FOR THE FAR NE COUNTIES WHERE SOME -SN OR
FLURRIES MAY LINGER BEFORE DEPARTING TO THE NE AS THE UPPER TROUGH
SHIFTS AWAY. AGAIN...MOISTURE IS LIMITED AND NOT EXPECTING MUCH
SNOWFALL ACCUMULATION ABOVE A FEW TENTHS OF AN INCH.

FORECAST THEN REMAINS DRY THROUGH WEDNESDAY NIGHT AS SURFACE HIGH
PRESSURE MOVES THROUGH. NEXT A PESKY WEAK CLIPPER SYSTEM IS PROGGED
TO PASS THROUGH THE GREAT LAKES ON THURSDAY. OPERATIONAL MODELS
AREN/T SHOWING TOO MUCH ASSOCIATED WITH THIS FEATURE...HOWEVER THE
MAJORITY OF THE ENSEMBLES SUGGEST POTENTIAL FOR SOME LIGHT
ACCUMULATING SNOWS FOR PARTS OF THE AREA. AS A RESULT...WILL KEEP
CHANCE POPS GOING FOR ON THURSDAY FOR LIGHT SNOW...WITH MINOR
ACCUMULATION OF A FEW TENTHS OF AN INCH POSSIBLE.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...

STUCK CLOSE TO ALLBLEND INITIALIZATION. MODEL GUIDANCE GENERALLY
SUGGESTS TWO SYSTEMS TO IMPACT THE AREA DURING THE LONG TERM...ONE
EARLY IN THE PERIOD AND ANOTHER TOWARD THE END OF THE WEEKEND INTO
EARLY NEXT WEEK. UNCERTAINTY REMAINS REGARDING HOW COLD IT WILL BE
AND THUS PRECIP TYPE FRIDAY AND FRIDAY NIGHT...ALTHOUGH SNOW
APPEARS FAIRLY LIKELY AT SOME POINT IN THE FORECAST AREA. THE
LATTER SYSTEM IS LIKELY TO BE ALL RAIN AS THERMAL PROFILES WARM
SIGNIFICANTLY BY THEN.

ASIDE FROM THE LARGER SCALE DETAILS...SIGNIFICANT TIMING AND
PLACEMENT DISCREPANCIES EXIST...THUS THE REASON FOR LITTLE
DEVIATION FROM INITIALIZATION.

&&

.AVIATION /DISCUSSION FOR THE 17/1330Z TAF UPDATE/...

THUNDERSTORMS DID NOT REACH AS FAR NORTH AS KLAF AND HAVE JUST ABOUT
FINISHED MOVING THROUGH KHUF. THEY WILL CONTINUE TO IMPACT KIND AND
KBMG FOR THE NEXT HOUR OR SO...AND SHOULD BE EAST OF ALL THE SITES
BY 15Z IF NOT BEFORE. INSERTED SOME TEMPO THUNDER AT KIND AND PUSHED
BACK EXIT OF THUNDER THERE.

COLD FRONT WILL PASS THROUGH THE SITES AROUND MIDDAY TODAY...WITH A
QUICK TRANSITION TO WEST/NORTHWEST WINDS WITH SOME RATHER STRONG
GUSTS...PERHAPS AS HIGH AS 35KT. ALSO COULD SEE IFR OR LOWER
CEILINGS WITH BEHIND THIS FRONTAL PASSAGE BASED ON UPSTREAM
OBSERVATIONS...AND ADDED THIS FOR SEVERAL HOURS IN THE AFTERNOON.

SOME SNOW SHOWERS BEHIND THE FRONT CANNOT BE RULED OUT...BUT WILL
JUST HOLD ONTO A VCSH MENTION AT THIS TIME...AS DEEP MOISTURE BEHIND
THE FRONT WILL BE LACKING IN OUR AREA.

WINDS WILL REMAIN GUSTY THROUGH THE DAY AND INTO THE
EVENING...BEFORE RELAXING LATE TONIGHT. CEILINGS WILL ALSO BREAK UP
LATE TONIGHT AS WELL.

&&

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