AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
1153 AM CST SAT DEC 7 2013

UPDATED AVIATION PORTION FOR 18Z TAF ISSUANCE

.SHORT TERM...TODAY...TONIGHT...AND SUNDAY
ISSUED AT 407 AM CST SAT DEC 7 2013

UPPER PATTERN TO CONTINUE TO SHOW BROAD TROF OVER MUCH OF CONUS
WITH HIGH OVER GULF OF ALASKA. FEATURE OF INTEREST THIS PERIOD IS
WAVE CURRENTLY MOVING THROUGH NORTHERN CANADA.

COLD CONTINUES TO BE THE FORECAST TODAY AND TONIGHT. HIGH PRESSURE
TO MOVE INTO STATE WITH WINDS EXPECTED TO GO LIGHT OVERNIGHT.
QUESTION WILL BE THE AMOUNT OF CLOUD LATER TONIGHT AND ITS AFFECT
ON TEMPS. SYSTEM HAS TO OVERCOME A LOT OF DRY AIR. HAVE LOWERED
TEMPS A BIT...ESPECIALLY NORTH WHERE AM THINKING HIGH CLOUDS WILL
BE LATE TO ARRIVE.

MODELS APPEAR TO BE SLOWING PCPN ARRIVAL A BIT FOR SUN AS WAVE
APPROACHES FROM THE WEST. SOUNDINGS SUGGEST DOES NOT SATURATE IN
THE EAST UNTIL MID TO LATE MORNING. THINKING WILL SEE SOME VERY
LIGHT SNOW THROUGH THE MORNING...WITH STEADIER/LIGHT TO MODERATE
SNOW DURING THE AFTERNOON. LIFT PRESENT THROUGH DEEP DENDRITIC
GROWTH ZONE. GIVEN THIS AND TEMPS THINKING IS SNOW WILL BE LIGHT
AND FLUFFY TYPE. AMOUNTS EXPECTED SUPPORT ADVISORY BUT SINCE SNOW
DOES NOT START TIL LATER THIRD PERIOD HAVE DECIDED TO STAY WITH
ONLY ONE HEADLINE/WIND CHILL AT THIS TIME.

NOT SEEING MUCH SUPPORT FOR LAKE BAND FORMATION IN WIND FIELDS AS
THEY REMAIN LIGHT WITH HIGH OVERHEAD INTO SUN MORNING. LAYER OF
EAST TO SOUTHEAST WINDS INCREASE LATER IN AFTERNOON. LOOKS TO BE
MORE OF A LAKE ENHANCEMENT SCENARIO. WILL HAVE 1 TO 2 INCH HIGHER
TOTALS WITH ENHANCEMENT OVER THE EAST.

.LONG TERM...SUNDAY NIGHT THROUGH FRIDAY
ISSUED AT 407 AM CST SAT DEC 7 2013

AMPLIFIED MEAN FLOW TO PREVAIL THRU THE MIDDLE OF NEXT WEEK BEFORE
THE FLOW SPLITS OVER THE ERN PACIFIC AND BRINGS A DIFFERENT AIR
MASS TO NE WI. INITIAL ACCUMULATING SNOW EVENT TO BE EXITING THE
REGION ON MON...TO BE FOLLOWED BY A PAIR OF WEAKER SYSTEMS ON TUE
AND TOWARD NEXT WEEKEND. ARCTIC AIR MASS TO BRIEFLY ABATE...BUT
MAKE ANOTHER APPEARANCE MID-WEEK. AS THE PATTERN BREAKS DOWN...
TEMPS COULD MAKE A RUN TOWARD NORMAL LEVELS.

THE SFC LOW IS NOW FCST TO TRACK TOWARD NRN SECTIONS OF LK HURON
SUNDAY NGT...ACCOMPANIED BY A MID-LEVEL SHORTWAVE TROF AND
FAVORABLE UPR JET DYNAMICS. SNOW TO ALREADY BE FALLING WITH THE
STRONGEST LIFT/FORCING OCCURRING DURING THE EVENING HOURS...
ESPECIALLY OVER THE SE HALF OF THE FCST AREA. ADDITIONAL
ACCUMULATIONS TO RANGE FROM 1 TO 3 INCHES OVER CNTRL WI...TO 3 TO
5 INCHES ALONG LAKE MI DUE TO AN INITIAL LAKE ENHANCEMENT BEFORE
WINDS SHIFT TO THE W-NW.

ANY LEFTOVER LIGHT SNOW OVER NE WI SHOULD EXIT EARLY MON MORNING
AS THE ENTIRE SYSTEM QUICKLY HEADS TOWARD E-CNTRL ONTARIO. ANOTHER
SURGE OF ARCTIC AIR WL SWEEP ACROSS WI ON BLUSTERY WEST WINDS AND
THIS MAY LEAD TO BLOWING/DRIFTING OF THE NEW SNOW...ESPECIALLY ON
NORTH-SOUTH ROADWAYS. THE ONSET OF CAA WL PREVENT MUCH OF ANY TEMP
RISE ON MON WITH READINGS REMAINING IN THE TEENS TO AROUND 20 DEGS
WITH WIND CHILLS IN THE SINGLE DIGITS ABOVE OR BELOW ZERO.

A WEAK SFC RDG SLIDES ACROSS WI MON EVENING AND WL BRIEFLY ALLOW
SKIES TO BECOME PARTLY CLOUDY. HOWEVER...MDLS CONT TO SHOW A FAST-
MOVING...COMPACT SHORTWAVE TROF TO DIG INTO THE WRN GREAT LAKES
LATER MON NGT. CLOUDS WL BEGIN TO INCREASE ONCE AGAIN OVER NE WI
WITH SUFFICIENT FORCING TO AT LEAST BRING A SMALL CHC OF LIGHT
SNOW TO CNTRL WI DESPITE A LACK OF MOISTURE. THE INCREASE IN
CLOUDS WL PREVENT A COMPLETE COLLAPSE IN TEMPS...HOWEVER IT WL
STILL BE VERY COLD WITH READINGS RANGING FROM THE SINGLE DIGITS
ABOVE ZERO NEAR LAKE MI...TO AROUND 10 BELOW ZERO OVER N-CNTRL WI.
THIS SYSTEM IS FCST TO MOVE PRIMARILY THRU NRN SECTIONS OF THE
GREAT LAKES ON TUE...THUS SLIGHTLY HIGHER POPS FOR NRN WI. DO NOT
ANTICIPATE MUCH IN THE WAY OF ACCUMULATION...HOWEVER THIS SYSTEM
WL PULL THE NEXT SURGE OF ARCTIC AIR INTO WI WITH 8H TEMPS
DROPPING TO AROUND -20C BY 00Z WED. MAX TEMPS FOR TUE WL AGAIN BE
A GOOD 10 TO 20 DEGS BELOW NORMAL.

THE NEXT ARCTIC HI PRES AREA IS EXPECTED TO MOVE SE INTO THE NRN
PLAINS TUE NGT WITH AN EWD EXTENSION TOWARD THE WRN GREAT LAKES.
SKY CONDITIONS ARE FCST TO BECOME PARTLY CLOUDY OVRNGT AND WITH
THE ARCTIC AIR MASS FIRMLY IN PLACE AND A SNOWPACK ON THE GROUND...
TEMPS SHOULD HAVE NO PROBLEM FALLING BELOW ZERO AWAY FROM LAKE MI.
IN FACT...MAY NEED TO LOWER VALUES ACROSS CNTRL WI INTO THE TEENS
BELOW ZERO. WHEN ONE ADDS A WEST WIND OF 10 TO 15 MPH...WE COULD
BE LOOKING AT WIND CHILL ADVISORY OR EVEN WIND CHILL WARNINGS IF
WINDS REMAIN STRONG ENUF. THE SFC HI BUILDS ACROSS THE MIDWEST ON
WED AND EVEN WITH SOME SUNSHINE...MAX TEMPS MAY NOT GET OUT OF THE
NEGATIVE NUMBERS OVER N-CNTRL WI.

THE CORE OF THE SFC HI TO SLIDE E-SE TOWARD THE OHIO RIVER VALLEY
BY THU WITH WEAK RIDGING EXTENDED NWWD INTO WI. THE CRUX OF THE
ARCTIC AIR IS PROGGED TO BEGIN RETREATING BACK INTO CANADA BY THIS
TIME...THUS EXPECT TO SEE TEMPS MAKE A RECOVERY INTO THE TEENS
(STILL WELL BELOW NORMAL).

BY THE END OF THE NEXT WEEK...THE MEAN FLOW TO HAVE SPLIT OVER THE
ERN PACIFIC WITH A RATHER FLAT FLOW ACROSS THE CONUS. THIS PATTERN
SHIFT SHOULD ALLOW TEMPS TO MAKE A MOVE AT LEAST CLOSER TO NORMAL
WITH MAX TEMPS BOTH FRI AND SAT RANGING FROM AROUND 20 DEGS NORTH
TO THE MIDDLE 20S OVER E-CNTRL WI. THE BIGGER PROBLEM TO DEAL WITH
WOULD BE PCPN CHCS...STARTING WITH ISEN LIFT ON FRI AND A WEAK NRN
STREAM SYSTEM ON SAT. MDLS ALWAYS STRUGGLE INITIALLY WHEN A MAJOR
PATTERN CHANGE OCCURS...THUS CONFIDENCE ON EXTENT OF ANY PCPN IS
RATHER LOW. HAVE PLACED SMALL POPS IN THE FCST FOR BOTH FRI AND
SAT.

SNOW BREAKING OUT IN THE 15Z TO 18Z TIME FRAME OVER CENTRAL

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH CENTRAL AND NORTHEAST
WISCONSIN.

.DAY ONE...TODAY AND TONIGHT

THE PROBABILITY FOR WIDESPREAD HAZARDOUS WEATHER IS LOW.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

THE NEXT CHANCE FOR ACCUMULATING SNOWS ARRIVES SUNDAY MORNING OR
EARLY SUNDAY AFTERNOON...AND CONTINUES INTO MONDAY MORNING AS AN
AREA OF LOW PRESSURE LIFTS NORTHEAST INTO THE GREAT LAKES. IT
APPEARS THAT SEVERAL INCHES OF SNOW ARE LIKELY ACROSS MUCH OF
CENTRAL INTO NORTHEAST WISCONSIN. SNOWFALL TOTALS COULD BE HIGHER
NEAR LAKE MICHIGAN DUE TO A SOUTHEAST FLOW OFF THE LAKE. IF THE
TRACK OF THE SURFACE LOW DOES NOT CHANGE...A WINTER WEATHER
ADVISORY WILL BE NEEDED FOR SUNDAY AFTERNOON THROUGH SUNDAY NIGHT
ACROSS ALL OF NORTHEAST WISCONSIN.

ON MONDAY...GUSTY WEST WINDS MAY CAUSE SOME BLOWING AND DRIFTING
OF THE NEW SNOW...ESPECIALLY ACROSS NORTH TO SOUTH ROADS. ANOTHER
SURGE OF ARCTIC AIR IS EXPECTED THROUGH THE MID-WEEK PERIOD WITH
TEMPERATURES 15 TO 30 DEGREES BELOW NORMAL. THE COMBINATION OF
VERY COLD TEMPERATURES AND THE PERSISTENT WEST WINDS WILL GENERATE
DANGEROUSLY LOW WIND CHILLS TUESDAY AND WEDNESDAY. SOME MODERATION
OF THE ARCTIC AIR IS EXPECTED TOWARD THE END OF THE WORK WEEK.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY OR TONIGHT.
