AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
243 PM CST SAT DEC 17 2011

.SHORT TERM...UPPER TROUGH WILL EXIT THE REGION BY EARLY EVENING
WITH CLEARING FOR AWHILE FROM MID EVENING THROUGH SUNDAY DAYBREAK.
LOWS WILL NOT DROP TOO MUCH AS THERE IS LITTLE COLD AIR UPSTREAM
AND BOUNDARY LAYER WINDS WILL NOT DIMINISH VERY MUCH. WENT A
LITTLE ABOVE MOS GUIDANCE TONIGHT.

CLOUDS WILL INCREASE AGAIN SUNDAY AS THE NEXT UPPER SYSTEM
APPROACHES. LOW LEVEL WARM ADVECTION IS QUITE IMPRESSIVE WITH
850MB WINDS FORECAST TO INCREASE TO 45 TO 50 KNOTS DRIVING
TEMPERATURES AT THAT LEVEL WELL ABOVE 0C BY AFTERNOON. SURFACE
TEMPERATURES WOULD GET INTO THE 50S IF IT WERE NOT MID DECEMBER
AND WE COULD GET MIXING TO 850MB. SO WENT A DEGREE OR TWO ABOVE
MOS AND THINK 40F WILL BE TOPS IN SOUTH AND EASTERN PARTS OF THE
FORECAST AREA.

.LONG TERM...SUNDAY NIGHT THRU NEXT SATURDAY. NO MAJOR CHANGES TO
THE SYNOPTIC PATTERN ACROSS THE CONUS...WITH A SPLIT FLOW
CONTINUING. MAIN FORECAST CONCERN ARE FINDING NEXT CHANCE FOR
PRECIP.

MODELS CONTINUE TO SHOW A COLD FRONT QUICKLY CROSSING THE AREA
SUNDAY NIGHT...BRINGING A WIND SHIFT FROM SW TO NW...ALONG WITH AN
INCREASE IN CLOUD COVER. WILL STICK WITH DRY FRONTAL PASSAGE AS
MODELS SHOW LIMITED MOISTURE IN THE MID-LEVELS...AND BEST FORCING
ASSOCIATED WITH THE SURFACE LOW AND SHORTWAVE WELL NORTH OF THE
AREA. BUFKIT SOUNDINGS HINTING AT SOME DRIZZLE POTENTIAL...BUT
DEPTH OF MOISTURE DOES NOT LOOK DEEP ENOUGH. SOMETHING TO KEEP AN
EYE ON THOUGH. HIGH PRESSURE WILL BUILD INTO THE NORTHERN PLAINS
EARLY MONDAY...AND EXTEND/BUILD INTO WI DURING THE DAY. THIS WILL
BRING DRY WEATHER TO THE AREA. THE ONE EXCEPTION WILL BE FAR NORTH
CENTRAL WI...MAINLY VILAS CO...WHERE LAKE EFFECT SNOW SHOWERS WILL
BE POSSIBLE AS 850MB TEMPS TO AROUND -10C...AND DELTA-T VALUES
INCREASE INTO THE MIDDLE TEENS. SURFACE TO 850MB WINDS WILL VEER
FROM THE W SUNDAY EVENING...TO THE MORE FAVORABLE NW BY LATE
EVENING AND CONTINUE THRU MONDAY. WILL CONTINUE TO CARRY CHANCES
FOR SNOW SHOWERS FOR THIS PERIOD...WITH ONLY MINOR ACCUMULATIONS
EXPECTED. AS WINDS DIE OFF AND BACK MORE WESTERLY MONDAY
EVENING...THE THREAT FOR SNOW SHOWERS SHOULD COME TO AND END.

HIGH PRESSURE IN CONTROL MONDAY NIGHT...WITH CLEARING SKIES AND
COLDER TEMPS. WILL KEEP MOST PLACES NEAR 10 IN THE NORTH...HOWEVER
THE TYPICAL COLD SPOTS COULD DROP CLOSER TO ZERO. CLOUDS AND WINDS
HOLD ON LONGER ACROSS THE EAST...WITH TEMPS FALLING INTO THE
LOWER 20S. QUIET WEATHER LOOKS TO CONTINUE ON TUESDAY...AS MODELS
SHOW THE NORTHERN AND SOUTHERN STREAMS NOT PHASING SOON ENOUGH TO
BRING SNOW INTO NE WI...AS LOW PRESSURE AND A SHORTWAVE PASS
ACROSS THE OHIO VALLEY. CLOUD DEBRIS MAY SNEAK INTO PORTIONS OF
CENTRAL AND EAST CENTRAL WI AS THE SYSTEM PASSES TO OUR SOUTH. IT
SHOULD BE NOTED THAT THE LATEST ECMWF HAS DRIFTED A LITTLE NORTH
WITH THE SYSTEM...BRINGING LIGHT SNOW TO THE LAKESHORE...AND MORE
CLOUDS TO THE STATE. WILL NOT MAKE ANY CHANGES TO THE DRY
FORECAST...BUT SOMETHING TO KEEP IN MIND AS MODELS STILL PINNING
DOWN EXACTLY HOW THE UPPER LOW EJECTS OUT OF THE SOUTHWESTERN US.

THE NORTHERN STREAM SHORTWAVE THAT DID NOT PHASE WITH THE SYSTEM
OVER THE OHIO VALLEY WILL BE THE NEXT MAJOR WEATHER MAKER AS IT
DIVES INTO THE NORTHERN PLAINS WEDNESDAY...AS TRACKS ACROSS THE
GREAT LAKES ON THURSDAY. THIS SYSTEM WILL SWING A COLD FRONT
ACROSS THE STATE ON WED NIGHT. LOW/MID LEVELS TOO DRY FOR PRECIP
ON WED...BUT AS COLD FRONT AND UPPER TROUGH APPROACH...AND MOISTURE
INCREASES...THE CHANCE FOR LIGHT SNOW WILL INCREASE FROM NW TO SE
ACROSS THE AREA. NOT EXPECTING MUCH ACCUMULATION. NOT AN IMPRESSIVE
SYSTEM PRECIP-WISE...SO WILL KEEP MOST POPS IN THE SLIGHT
CATEGORY...EXCEPT ACROSS THE FAR NORTH. SOME LAKE EFFECT SNOW IS
POSSIBLE BEHIND THE SYSTEM IN THE LAKE SUPERIOR SNOW BELT THURSDAY
NIGHT AND EARLY FRIDAY BEFORE WINDS BACK TO THE WEST.
&&

.AVIATION...CIGS GENERALLY BETWEEN 1000' AND 2000' AGL WITH LOCAL
IFR CIGS AND VSBYS IN SNOW SHOWERS UNTIL 00Z. CLEARING EXPECTED
FROM WEST TO EAST DURING THE EVENING. VFR CIGS EXPECTED SUNDAY.
&&

.GRB WATCHES/WARNINGS/ADVISORIES...
NONE.
