109 AM EST TUE JAN 11 2011

.AVIATION...
MAIN CHANGE FOR THE 06Z TAFS IS TO CONTINUE TREND OF SLIGHTLY
SLOWING DOWN ONSET OF LIGHT SNOW. DRY EASTERLY FLOW HAS
DISCOURAGED EASTWARD EXPANSION OF -SN THROUGH THE NIGHT. WATER
VAPOR IMAGERY INDICATING MORE VIGOROUS UPPER LEVEL DISTURBANCE
ASSOCIATED WITH UPPER LEVEL JET STREAK NOSING INTO EASTERN
MISSOURI AT THIS TIME. VEERING LOW/MID LEVEL WINDS OVERNIGHT
SHOULD ALLOW FOR SOME MORE SUBSTANTIAL MOISTURE RETURN TOWARD
12Z...ESPECIALLY AT KFWA. BASED ON TIMING FORCING FROM THIS
DISTURBANCE...IT APPEARS PERIOD OF HEAVIEST SNOW WILL FALL IN THE
16Z-22Z TIME FRAME WITH LIFR CONDITIONS LIKELY...ESPECIALLY AT
KFWA DURING THIS PERIOD. WRAP AROUND MOISTURE INTO NORTHEAST
INDIANA AND NORTHWEST OHIO WILL LIKELY ALLOW IFR CONDITIONS TO
LINGER AT KFWA INTO THIS EVENING...AND FOCUS WILL EVENTUALLY
SHIFT BACK TO THE WEST WITH LAKE EFFECT SNOW POTENTIAL ON THE BACK
SIDE OF THIS SYSTEM. FOR MUCH OF THE EVENING HOURS...EXPECTING
DOMINANT LAKE EFFECT BANDING TO REMAIN WEST OF KSBN...WITH GREATER
POTENTIAL OF KSBN GETTING INTO HEAVIER LAKE EFFECT SNOW LATE
TUESDAY NIGHT AND MORE LIKELY BY WEDNESDAY MORNING AS LOW LEVEL
WINDS SLIGHTLY BACK TO MORE NORTHEAST AS SFC LOW DEPARTS EASTERN
GREAT LAKES. LIGHT EAST NORTHEAST WINDS WILL SLIGHTLY BACK TODAY
WITH SFC LOW PASSAGE SOUTH OF THE AREA...EVENTUALLY BECOMING
NORTHWEST TONIGHT. TIGHTENING GRADIENT AND WEAK COLD ADVECTION
TONIGHT SHOULD PROMOTE SOME GUSTS TO 15 TO 20 KNOTS LATER THIS
EVENING.

.PREV DISCUSSION... /ISSUED 913 PM EST MON JAN 10 2011/

UPDATE...
ONLY CHANGE TO FORECAST THIS EVENING WILL BE TO SLIGHTLY PUSH BACK
ONSET OF WINTER WEATHER ADVISORY HEADLINE FOR ESPECIALLY NORTHEAST
PORTIONS OF THE FORECAST AREA.

WATER VAPOR IMAGERY/RUC ANALYSIS INDICATING LEAD SHORT WAVE
LIFTING NORTHWARD ACROSS SWRN WISCONSIN AT THIS TIME WHICH HAS
ALLOWED SOME LIGHT SNOW AND FLURRIES TO OVERSPREAD SOUTHERN
WISCONSIN. LULL IN MID/UPPER FORCING BEHIND THIS INITIAL SHORT
WAVE WITH NEXT STRONGER VORT MAX STILL POSITIONED ACROSS EASTERN
KANSAS IN ASSOCIATION WITH STRONG UPPER JET STREAK. THIS VORT MAX
AND NOSE OF UPPER JET WILL APPROACH THE AREA DURING THE OVERNIGHT
HOURS. LARGE SCALE ISENTROPIC UPGLIDE WILL STRENGTHEN AFTER 06Z
TONIGHT AS LOW LEVEL WINDS BEGIN TO VEER. NAM ISENTROPIC ANALYSIS
OF 285K SFC DEPICTING SOME VERY DRY MIXING RATIOS INITIALLY ACROSS
THE AREA GENERALLY AT OR BELOW 0.25 G/KG. BETTER CHANCE OF
ACCUMULATING SNOW APPEARS TO BE CLOSER TO THE 12Z TIMEFRAME WHEN
UPPER SUPPORT INCREASES AND MORE SUBSTANTIAL LOW LEVEL MOISTURE
ADVECTION OCCURS. GIVEN THE ABOVE FACTORS...WILL LIKELY PUSH BACK
ONSET OF ADVISORY A FEW HOURS...ESPECIALLY FOR NORTHEAST PORTIONS
OF THE ADVISORY AREA TO AROUND 12Z. OTHERWISE...GOING FORECAST
SEEMS TO HAVE A GOOD HANDLE ON THINGS AND NO CHANGES TO SNOW
TOTALS AT THIS TIME.

PREV DISCUSSION... /ISSUED 344 PM EST MON JAN 10 2011/

SHORT TERM.../TODAY THROUGH TUESDAY NIGHT/...

MORE SNOW TO FALL ACROSS THE AREA FOLLOWED BY ANOTHER
SIGNIFICANT LAKE EFFECT EVENT...

WINTER STORM POISED TO MOVE ACROSS THE CWA ON TUESDAY CURRENTLY
MOVING THROUGH THE CENTRAL PLAINS WITH HEALTHY SHTWV DEFINED ON W/V
IMAGERY AND A VAST SWATH OF MODERATE SNOW FALLING ACROSS MISSOURI. SFC
RESPONSE LIFTS THROUGH THE LOWER OHIO VALLEY WHILE UPPER TROUGH
SWINGS OVERHEAD AS SHORTWAVE GAINS SPEED AHEAD OF PHASING WITH
SOUTHERN SYSTEM AND RAPIDLY STRENGTHENING OFF THE NEW ENGLAND
COAST. NO SIGNIFICANT CHANGES FROM PREV MODEL CYCLES AND FAVORING
SLIGHTLY FASTER EASTWARD PROGRESSION OF PRECIP AT ONSET PER GFS AS
ISENTROPIC ASCENT ARRIVES...BUT NOT BEING TOO AGGRESSIVE AS THE
MODELS MAY BE A BIT QUICK TO OVERCOME/SATURATE DRY LLEVELS AFTER
06Z IN THE WEST..TO 09Z EAST. AS THIS ASCENT BEGINS TO WANE
STRONGER DYNAMICS ENTER THE PICTURE WITH BEST FORCING CONTINUING
TO FAVOR SOUTHERN PORTION OF THE CWA WHERE UPPER DIVERGENCE
/QVECTORS /STRONGEST FRONTOGENETICAL FORCING ARE COLLOCATED. ALSO
INDICATIONS IN THETA-E FIELDS THAT WARM CONVEYOR/EARLY TROWAL
FORMATION GETS AN OPPORTUNITY TO IMPACT EASTERN REGIONS BEFORE
SYSTEM DEPARTS. OVERALL EXPECTING A GENERALIZED 3-6 INCH SNOWFALL
SOUTH WITH THE HIGHER AMOUNTS ASSOCIATED WITH MESOBANDING FEATURES
IN THE SOUTH WHERE STRONGEST FRONTOGENETICAL FORCING IS
PRESENT...AND HAVE HOISTED AN ADVISORY IN THESE AREAS. LESSER
AMOUNTS NORTHWEST AS THEY MISS OUT ON THE ABOVE FACTORS AND THOUGH
THEY WILL SEE SOME SNOW...AFTER COLLAB WITH SURROUNDING OFFICES
HAVE LIMITED THE NW EXTENT OF HIGHLIGHTS.

ON THE BACK SIDE WINDS BECOME NNW RAMPING UP ANOTHER LAKE RESPONSE
BEGINNING TUESDAY NIGHT. PARAMETERS ARE SIMILAR TO PREV CYCLES WITH
DELTA TS AND EQL HEIGHTS SUFFICIENT BUT NOT IMPRESSIVE HWVR PLENTY
OF MOISTURE PRESENT WITH LONG AXIS FETCH SHOULD ALLOW DEVELOPMENT OF
SINGLE BAND. LAKE EFFECT CONTINUES INTO THE LONG TERM...AND LAKE
EFFECT SNOW WATCH REMAINS IN PLACE WITH NO CHANGES.

LONG TERM...

SNOWY START TO THE LONG TERM WITH LAKE EFFECT CONTINUING ACROSS
NORTHWESTERN PORTIONS OF THE FORECAST AREA AS NORTHWEST FLOW IS IN
PLACE. DID NOT MAKE MANY CHANGES IN TERMS OF AMTS ACROSS THESE AREAS
AND WILL CONT WITH LAKE EFFECT SNOW WATCH HEADLINE AS BOTH THE LOCAL
WRF AND NAM STILL IN AGREEMENT IN TERMS OF THE LOCATION OF THE BAND.
BY THURSDAY MORNING LAKE EFFECT SNOW WILL BEGIN TO DIMINISH AS FLOW TURNS
MORE WESTERLY...THEN SOUTHERLY BY FRIDAY AS WAA BEGINS TO FILTER IN
WITH HIGH PRESSURE BUILDING IN FROM THE WEST. CLOUDS WILL BE SLOW TO
GO ANYWHERE THROUGH THE PD AND WITH ANOTHER SURFACE LOW PRESSURE
SYSTEM WITH ASSOCIATED COLD FRONT TRACKING EASTWARD ACROSS THE
NORTHERN GREAT LAKES BY THE START OF THE WEEKEND...EXPECT CLOUD
COVER TO REMAIN...ANOTHER ROUND OF SNOW...AND COLDER TEMPERATURES TO
PERSIST. USED A BLEND OF THE MODELS THROUGH MOST OF THE PERIOD AS
BOTH THE GFS/ECMWF IN FAIRLY DECENT CONSISTENCY WITH TIMING/TRACK OF
EARLY WEEKEND SYSTEM.

BIGGEST CHALLENGES THIS FCST PERIOD ARE THE TEMPERATURES GIVEN LAKE
EFFECT AND SNOWPACK THAT WILL BE ON THE GROUND FROM TUES SYSTEM.
HIGHS WILL GENERALLY BE IN THE 20S THROUGH THE WEEKEND.
HOWEVER...LOW TEMPERATURES ARE MORE DIFFICULT. WED NIGHT GIVEN LAKE
EFFECT SNOW/CLOUDS WENT WITH SLIGHTLY HIGHER TEMPS...IN THE
TEENS...AND THEN SINGLE DIGITS PRACTICALLY EVERYWHERE ELSE GIVEN
POSSIBLY LESS CLOUDS AND SNOWPACK. SLIGHTLY WARMER LOWS EXPECTED
FRIDAY NIGHT WITH SOUTHERLY FLOW IN PLACE THEN A RETURN TO SINGLE
