AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
607 AM CST TUE DEC 6 2011

UPDATED AVIATION PORTION FOR 12Z TAF ISSUANCE

.SHORT TERM...TODAY THROUGH WEDNESDAY.

FORECAST CONCERNS THIS PERIOD...CLOUDS

LATEST RUC ANALYSIS AND SATELLITE/RADAR IMAGERY SHOW HIGH PRESSURE
STRETCHING FROM WESTERN LAKE SUPERIOR INTO WESTERN IA. LOWER CLOUD
CLEARING OVER MUCH OF EASTERN WI AS DRIER AIR...SEEN ON GRB
SOUNDING...WORKING IN. CLOUDS HANGING TOUGH OVER WESTERN PART OF
STATE. SURFACE HIGH WILL CONTINUE TO SHIFT OVER STATE
TODAY...EXITING TONIGHT WITH COLD FRONT ASSOCIATED WITH LOW MOVING
THROUGH NORTHERN CANADA MOVING THROUGH STATE ON WED.

QUESTION IS WHAT WILL HAPPEN WITH CLOUDS TODAY. AREA OF
CONVERGENCE ASSOCIATED WITH WEAK SURFACE TROF OVER WESTERN WI TO
WEAKEN THIS MORNING. SOME MODELS SHOW LOWER CLOUD MOVING BACK INTO
EASTERN WI LATE TODAY AS LOW LEVEL WINDS SHIFT TO THE SOUTHWEST LATE.
SOME SHOW CLOUD DISSIPATING THROUGH THE DAY AS SUPPORT WEAKENS.
HAVE LEANED TOWARDS CANADIAN THAT SHOWS CURRENT CLEARING OVER
EASTERN AND NORTH CENTRAL WI...THOUGH WILL STAY WITH PARTLY
CLOUDY/PARTLY SUNNY WORDING GIVEN CIRRUS MOVING THROUGH AND SOME
UNCERTAINTY. CLOUDS CONTINUE TO MOVE SOUTH OFF LAKE
SUPERIOR/MICHIGAN IN THE FAR EAST. THUS CLEARING SLOWED A BIT FROM
PREVIOUS FORECAST...THOUGH LITTLE CHANGE MADE IN TEMPERATURE
FORECAST.

.LONG TERM...WEDNESDAY NIGHT THROUGH MONDAY.

MODELS HAD AN UPPER TROUGH OVER MUCH OF THE CONUS EARLY IN THE
PERIOD...WITH THE FLOW BECOMING ZONAL OVER THE UPPER GREAT LAKES BY
EARLY NEXT WEEK.

AN ARCTIC FRONT WILL BRING MUCH COLDER AIR INTO THE FORECAST AREA
ON THURSDAY. HAVE A SLIGHT CHANCE OF SNOW SHOWERS IN VILAS COUNTY
FOR THE END OF THE WORK WEEK. LAPSE RATES OVER LAKE SUPERIOR
SHOULD BE STEEP...BUT WINDS APPEARED TO HAVE TOO MUCH OF A
WESTERLY COMPONENT TO GO AS HIGH AS CHANCE POPS. NEAR OR ABOVE
NORMAL TEMPERATURES CAN BE EXPECTED BY SUNDAY AS A SURFACE RIDGE
PASSES EAST OF THE AREA AND SOUTHWEST WINDS BRING WARMER AIR INTO
THE STATE.

HAVE SOME SLIGHT CHANCE POPS LATE IN THE PERIOD WITH SHORT WAVE
ENERGY AND A SURFACE LOW APPROACHING WISCONSIN. MAY NEED TO GO
WITH HIGHER POPS IN THE AFTERNOON FORECAST PACKAGE OR TOMORROW
MORNING IF CONDITIONS APPEAR MORE FAVORABLE FOR PRECIPITATION.
&&

.AVIATION...DRIER AIR WORKING IN OVER EASTERN WI HAS CLEARED SKIES
FOR MUCH OF EASTERN WI AND NORTH CENTRAL WI...NOW WORKING INTO
CENTRAL WI. SUPPORT FOR FLURRIES/CLOUDS JUST WEST OF CWA/AUW TO
DIMINISH THIS MORNING. THOUGHTS ARE CLOUDS WILL CONTINUE TO DIMINISH
OVER WEST. INCREASING SOUTHWEST WINDS THIS EVENING...30 KTS AT 2K
FT. THOUGH NOT STRONG ENOUGH DIFFERENCE FROM SURFACE FOR LLWS AT
THIS TIME.
