AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
243 PM CST FRI DEC 7 2012

.SHORT TERM...TONIGHT AND SATURDAY...THE MAIN FCST CONCERNS ARE
PCPN TRENDS AND SNOWFALL AMOUNTS TONIGHT INTO EARLY SATURDAY...
AND SKY COVER AND TEMPERATURES ON SATURDAY.

A LARGE AREA OF LIGHT TO OCCASIONALLY MODERATE SNOW WAS ONGOING
OVER SE SD...SW MN AND NE IA THIS AFTERNOON. THE SNOW WAS ASSOCIATED
WITH AN APPROACHING S/W TROF...A JET STREAK...AND MID-LEVEL
FRONTOGENETIC FORCING. OVER WI...THE LOWER ATMOSPHERE REMAINED
FAIRLY DRY...WITH MAINLY MID-LEVEL CLOUDS OVERSPREADING THE REGION
AT THIS TIME.

BASED ON UPSTREAM RADAR/SFC OBS TRENDS...THE STRENGTH OF THE INCOMING
FORCING...AND A MODEL TREND TOWARD BETTER SATURATION OF THE LOWER
ATMOSPHERE...HAVE DECIDED TO INCREASE POPS TO LIKELY OVER THE
SOUTHERN TWO-THIRDS OF THE CWA...AND MENTION SOME ACCUMULATIONS IN
THE FCST. LITTLE ACCUMULATION IS EXPECTED IN THE FAR NORTH...BUT
MUCH OF THE CWA SHOULD SEE A HALF INCH TO AN INCH. NE WINDS...
COMBINED WITH LAKE-H8 DELTA-T'S OF 13-14 C MAY LEAD TO SOME LAKE-
ENHANCEMENT OVER KEWAUNEE/MANITOWOC COUNTIES...ALTHOUGH THE
POTENTIAL FOR A BRIEF MIX WITH RAIN MAY REDUCE THE ACCUMS RIGHT
ALONG THE SHORELINE. WILL HEDGE THE SNOWFALL FCST HIGHER THERE...
AND MENTION ACCUMS OF 1-2 INCHES FOR KEW/MTW COUNTIES. ANOTHER
SCENARIO WHERE HIGHER ACCUMS COULD BE SEEN IS IF A WELL-DEFINED
FRONTOGENTIC BAND DEVELOPS. THERE WAS A NICE BAND OVER SOUTH
DAKOTA EARLIER...WITH SOME 1/2SM VSBYS NOTED ON OBS SITES WITHIN
IT. THERE IS A STEADY SIGNAL FOR FRONTOGENETIC FORCING AND SOME
EPV (INSTABILITY) DURING THE OVERNIGHT PERIOD...ESP ACROSS PARTS
OF C/EC WI...SO THIS BEARS WATCHING FOR A NARROW CORRIDOR OF
HIGHER SNOWFALL AMOUNTS.

THE SNOW IS EXPECTED TO PULL OUT OF EC WI EARLY ON SATURDAY...WITH
A GRADUAL CLEARING TREND DURING THE LATE MORNING AND EARLY
AFTERNOON. EXPECT PARTLY CLOUDY CONDITONS BY AFTERNOON...WITH
HIGHS ONLY WARMING INTO THE 30S.

.LONG TERM...SATURDAY NIGHT THROUGH THURSDAY.

MODELS ARE IN DECENT AGREEMENT WITH THE LARGE SCALE FEATURES THROUGH
ABOUT 00Z TUESDAY BEFORE SPLIT FLOW DEVELOPS OVER MUCH OF THE
CONTINENT...WHILE RIDGING REMAINS PRESENT OVER THE EASTERN PACIFIC
AND ALSO THE NORTHERN ATLANTIC.  OBVIOUSLY THE MAIN FORECAST CONCERN
OVER THIS PERIOD IS THE STORM SYSTEM THAT WILL IMPACT THE AREA
MAINLY LATE SATURDAY NIGHT THROUGH SUNDAY NIGHT.  MEDIUM RANGE
MODELS CONTINUE TO HAVE SOME DIFFERENCES IN REGARDS TO THEIR MASS
FIELDS AND ALSO THEIR TIMING...WHICH SIGNIFICANTLY IMPACTS THE
DETAILS OF THIS SYSTEM.  LATEST GFS ENSEMBLE MEAN AND SREF ENSEMBLE
INDICATES A FLATTER AND MORE SUPPRESSED NORTHERN STREAM WAVE WHICH
FAVORS THE ECMWF SOLUTION...WHILE THE LATEST GFS/NAM HAVE A MORE
DEVELOPED NORTHERN STREAM WAVE AND ASSOCIATED SURFACE LOW.  THE
ECMWF REMAINS THE MOST CONSISTENT MODEL OVER THE PAST SEVERAL DAYS
OF RUNS SO WILL SIDE WITH THAT DIRECTION.  FOR LATER PERIODS...A
BLEND OF THE GFS/ECMWF WILL SUFFICE.

SATURDAY NIGHT THROUGH MONDAY...POSITIVELY TILTED NORTHERN STREAM
SHORTWAVE TROUGH WILL BE MOVING EAST OVER THE NORTHERN PLAINS
SATURDAY NIGHT.  AS THE WAVE DRAWS CLOSER TO THE REGION...WEAK
ISENTROPIC ASCENT WILL DEVELOP ON THE 280-285K PRESSURE SURFACES
LATE SATURDAY NIGHT.  MUCH OF THIS ASCENT WILL GO INTO SATURATING
THE MID LEVELS...SO PRECIP MAY NOT ARRIVE UNTIL LATE SATURDAY NIGHT
INTO CENTRAL WISCONSIN.  THOUGH THE MAIN SURFACE LOW WILL DEVELOP
OVER THE MID-MISSISSIPPI VALLEY...AN INVERTED SURFACE TROUGH AND
BROAD 850MB LOW WILL PASS ACROSS THE REGION ON SUNDAY.  DO SEE
EVIDENCE OF A WEAK COUPLED JET STRUCTURE THAT WILL MOVE INTO SOUTHERN
AND CENTRAL WISCONSIN SUNDAY MORNING AND BROAD UPPER DIVERGENCE TO
YIELD DECENT UPPER SUPPORT.  THE BEST FORCING SEEMS TO PASS OVER
CENTRAL TO NORTH-CENTRAL WISCONSIN...WHERE THE COLDER AIR WILL BE IN
PLACE ALOFT.  THERE IS ALSO NEGATIVE EPV OVER NORTHERN WISCONSIN ON
SUNDAY WITHIN THE ISENTROPIC ASCENT ZONE...THOUGH THE DENDRITIC
GROWTH ZONE IS NOT PARTICULARLY DEEP.  FURTHER SOUTH...TEMPERATURE
PROFILES DO LOOK COLDER OVER CENTRAL AND EASTERN WISCONSIN THAN THEY
DID YESTERDAY...WHICH WOULD CORRELATE TO MORE OF A STRAIGHT SNOWFALL
AS OPPOSED TO A MIX OR ALL RAIN (EXCEPT NEAR THE LAKESHORE).  HOWEVER...
TOUGH TO BECOME CONFIDENT IN THE THERMAL PROFILE HERE...AS MODELS
HAVE BEEN WAFFLING BACK AND FORTH. TIMING-WISE...THE BULK OF THE
PRECIP NOW LOOKS TO OCCUR LATE SUNDAY MORNING THROUGH SUNDAY
AFTERNOON BEFORE DIMINISHING SUNDAY EVENING FROM SOUTHWEST TO
NORTHEAST. BLENDING VARIOUS QPFS AND SNOWFALL RATIO GRIDS YIELDS
ABOUT 4-6 INCHES OVER CENTRAL AND NORTH-CENTRAL WISCONSIN...AND
2-4 INCHES FROM THE LAKESHORE TO THE WESTERN PART OF THE FOX
VALLEY AND BAYSHORE. AN ADDITIONAL 1-3 INCHES MAY FALL OVER N-C
WISCONSIN AS LAKE EFFECT SNOW RAMPS UP LATE SUNDAY NIGHT THROUGH
MIDDAY MONDAY. WINDS WILL NOT BE MUCH OF A FACTOR THROUGH THIS
EVENT AS THE PRESSURE GRADIENT WILL BE BAGGING WITH THE INVERTED
TROUGH MOVING THROUGH. BASED ON COORDINATION WITH SURROUNDING
OFFICES...WILL HOIST A WINTER STORM WATCH NORTHWEST OF A MARATHON
CO. TO NORTHERN MARINETTE CO. LINE FOR 4-6 INCHES OF SNOW PLUS THE
FIRST SNOW OF THE SEASON FOR MANY PLACES.

ARCTIC AIR WILL FILTER ACROSS THE REGION BEHIND THE SYSTEM LATE
SUNDAY NIGHT THROUGH MONDAY.  SOME SNOW SHOWERS/FLURRIES WILL LIKELY
LINGER ON MONDAY OVER NE WISCONSIN WHERE DEEPER MOISTURE AND
CYCLONIC FLOW WILL BE SLOW TO MOVE OUT.  PARTIAL CLEARING WILL WORK
INTO CENTRAL AND POSSIBLY NORTH-CENTRAL WISCONSIN MONDAY AFTERNOON
AS THE SURFACE RIDGE AXIS MOVES IN.  HIGHS ONLY IN THE 20S.

REST OF THE FORECAST...HIGH PRESSURE WILL MOVE OVER THE AREA MONDAY
NIGHT.  WITH AT LEAST A PERIOD OF CLEARING AND FRESH SNOW
COVER...TEMPS COULD REALLY TAKE A NOSE DIVE.  WILL LOWER TEMPS.  THE
NEXT NORTHERN STREAM SHORTWAVE WILL PUSH A LOW PRESSURE SYSTEM
ACROSS LAKE SUPERIOR OR FAR SOUTHERN ONTARIO ON TUESDAY.  WILL SEE
AN INCREASE OF MID AND HIGH CLOUDS AHEAD OF THIS SYSTEM...BUT THE
ONLY CHANCE OF SNOW WILL RESIDE OVER FAR N-C WISCONSIN WHERE AN
ARCTIC FRONT WILL DROP SOUTH IN THE AFTERNOON AND EVENING.
MODERATING TEMPS WILL OCCUR WEDNESDAY INTO WEDNESDAY NIGHT AS RETURN
FLOW RAMPS UP AHEAD OF THE NEXT FRONT DUE TO ARRIVE IN THE
THURSDAY/THURSDAY NIGHT PERIOD.  NOT MUCH FORCING ALOFT AS THE FRONT
APPROACHES SO POPS WILL BE LOW.
&&

.AVIATION...LIGHT NORTH FLOW OFF LAKE SUPERIOR WAS HELPING TO MAINTAIN
AN AREA OF MVFR CIGS OVER FAR NORTHERN WI EARLY THIS AFTERNOON. THESE
SHOULD GRADUALLY MIX OUT LATE THIS AFTERNOON. OTHERWISE...THE MAIN
AVIATION CONCERN WILL BE VSBYS/CIGS ASSOCIATED WITH LIGHT SNOW
TONIGHT INTO EARLY SATURDAY. CONDITIONS ARE EXPECTED TO DETERIORATE
TO MVFR/IFR ONCE THE STEADIER SNOW DEVELOPS. THE BEST PERIOD FOR
STEADY SNOW SHOULD BE FROM 04Z-10Z AT RHI/CWA/AUW...AND 08Z-13Z AT
ATW/GRB. THERE IS SOME POTENTIAL FOR SOME LAKE ENHANCEMENT IN PARTS
OF KEWAUNEE/MANITOWOC COUNTIES LATE TONIGHT INTO EARLY SATURDAY...
SO SNOW BANDS COULD BECOME MORE INTENSE THERE. THE SNOW COULD ALSO
BRIEDLY MIX WITH RAIN ALONG THE LKSHR.
