AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
346 AM EST FRI FEB 1 2013

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

&&

.SYNOPSIS...
ISSUED AT 323 AM EST FRI FEB 1 2013

A SERIES OF UPPER DISTURBANCES WITHIN A NORTHWESTERLY FLOW WILL
RESULT IN PERIODIC CHANCES FOR PRECIPITATION INTO EARLY NEXT WEEK.
HIGH PRESSURE IS EXPECTED DURING THE MIDDLE PARTS OF NEXT WEEK. A
FRONTAL SYSTEM MAY APPROACH THE AREA TOWARDS NEXT THURSDAY.

&&

.NEAR TERM /TODAY/...
ISSUED AT 323 AM EST FRI FEB 1 2013

WILL BE ISSUING A WIND CHILL ADVISORY FOR AREAS ROUGHLY NORTH OF
INTERSTATE 70 UNTIL 011600Z AS IT APPEARS EXPECTED TEMPERATURES AND
WINDS THROUGH LATE MORNING WILL RESULT IN WIND CHILLS AROUND
ADVISORY CRITERIA. WINDS SHOULD BEGIN TO SLACKEN OFF TOWARDS MIDDAY
AS PRESSURE GRADIENT AND COLD ADVECTION DIMINISH...SO EXPECTING WIND
CHILLS TO IMPROVE BY THEN.

OTHERWISE...LOW LEVEL LAPSE RATES REMAIN STEEP UNDER STRONG COLD
ADVECTION THIS MORNING...SO WILL KEEP SOME FLURRIES IN THE FORECAST
THROUGH THE LATE MORNING. SHOULD SEE A DECREASING TREND IN CLOUD
COVER DURING THE DAY AS COLD ADVECTION/LOW LEVEL LAPSE RATES
DIMINISH LATER TODAY.

BASED ON PROGGED LOW LEVEL THICKNESSES TODAY...WILL TAKE ABOUT 3
DEGREES OFF THE NAM MOS GUIDANCE.

&&

.SHORT TERM /TONIGHT THROUGH SUNDAY/...
ISSUED AT 323 AM EST FRI FEB 1 2013

MODELS INDICATE THE MAIN ITEM OF INTEREST DURING THIS PERIOD WILL BE
A DISTURBANCE THAT IS EXPECTED TO DROP SOUTHEAST INTO THE AREA ON
SATURDAY. LIFT ASSOCIATED WITH THIS DISTURBANCE LOOKS DECENT THROUGH
THE PRECIPITATION BEARING LAYER...BUT NOT OVERLY IMPRESSIVE. APPEARS
FROM THE MODEL DATA THAT THE MAIN LIFT WILL BE MOVING INTO THE AREA
ROUGHLY 020600Z-021800Z...SO WILL GO WITH LIKELY POPS FOR SNOW AFTER
MIDNIGHT TONIGHT THROUGH THE EARLY AFTERNOON HOURS ON SATURDAY.
STILL APPEARS A COUPLE OF INCHES ACCUMULATION IS LIKELY FROM THIS
SYSTEM.

MODELS SUGGEST THERE STILL MAY BE SOME UPPER ENERGY MOVING THROUGH
THE AREA SATURDAY NIGHT...SO WILL KEEP SOME CHANCE POPS GOING AT
THAT TIME. MOST OF THE OPERATIONAL AND ENSEMBLE DATA SUGGEST
PRECIPITATION THREAT WILL BE OVER BY SUNDAY...SO WILL GO DRY AT THAT
TIME.

PROGGED LOW LEVEL THICKNESSES SUGGEST THE GFS MOS TEMPERATURES
GUIDANCE LOOKS TOO COLD THROUGHOUT MOST OF THE PERIOD. WILL LEAN
TOWARDS THE WARMER NAM GUIDANCE.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
ISSUED AT 323 AM EST FRI FEB 1 2013

ENSEMBLES SEEM TO BE IN AGREEMENT WITH THE LARGE SCALE DETAILS OF
THE EXTENDED PERIOD AND THE ALLBLEND INITIALIZATION SEEMS REASONABLE
BASED ON THIS OUTPUT. THIS PERIOD WILL BE CHARACTERIZED BY A COUPLE
WEAK SYSTEMS ROTATING THROUGH A BROAD UPPER TROUGH...BRINGING
PERIODIC CHANCES FOR PRECIPITATION TO CENTRAL INDIANA THROUGH LATE
NEXT WORK WEEK.

FIRST SYSTEM MOVES THROUGH ON MONDAY/MONDAY NIGHT AND SHOULD BE COLD
ENOUGH TO PRODUCE ONLY LOW CHANCES FOR SNOW. ANOTHER QUICK SYSTEM
DIVES THROUGH THE AREA AGAIN ON TUESDAY AND PRODUCES CHANCE FOR SNOW
ACROSS THE NORTH AND A RAIN/SNOW MIX (SOUTH). VERY LIGHT PRECIP
AMOUNTS WITH BOTH FEATURES. NEXT SYSTEM MOVES THROUGH THU/THU NIGHT
AND ATTM COULD BRING A FAIR AMOUNT OF MOISTURE TO THE REGION AS
COMPARED TO THE LAST FEW DISTURBANCES...BUT THIS IS STILL VERY FAR
OUT IN THE FORECAST. GOOD ENOUGH FOR CHANCE POPS DURING THIS TIME
WITH PRECIP TYPE RANGING FROM ALL SNOW ACROSS THE NORTH TO A
RAIN/SNOW MIX SOUTH.

.AVIATION /DISCUSSION FOR THE 0106OOZ TAF ISSUANCE/...

ISSUED AT 345 AM EST FRI FEB 1 2013

0830Z UPDATE...ADDED A MFVR TEMPO GROUP FOR -SHSN UNTIL 11Z.

LOOKS LIKE THE LIGHT SNOW WILL FINALLY BE OVER BY ISSUANCE TIME.
MEANWHILE...CLEARING IS EXPECTED FROM SOUTHWEST TO NORTHEAST AFTER

DEGREES TO AROUND 20 KNOTS AND GUSTING TO NEAR 30 WILL REMAIN GUSTY
BUT GRADUALLY DROP OFF TO 10 TO 15 KNOTS BY 12Z WITH GUSTS BELOW 25
KNOTS. WINDS WILL DROP OFF EVEN FURTHER AND BECOME WEST AND
SOUTHWEST AS ARCTIC HIGH PRESSURE SETLLES SOUTHEAST ACROSS THE OHIO
VALLEY LATER TODAY. BY AFTERNOON...THE GUSTS SHOULD BE A MEMORY.

AFTER 04Z SATURDAY AHEAD OF A CLIPPER SYSTEM. WINDS WILL BE SOUTH
LESS THAN 10 KNOTS.
