AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
407 AM CST SAT DEC 10 2011

.SHORT TERM...TODAY THROUGH SUNDAY.

UPPER TROF NOW PASSING OFF TO EAST WITH A RETURN TO MORE ZONAL
PATTERN EXPECTED THROUGH THIS PERIOD. QUESTION IS HOW MUCH OF THE
WARMING WILL BE REALIZED AT THE SURFACE.

SFC HIGH PASSING TO THE SOUTH OF THE STATE OVERNIGHT. COLD AIR
MASS...WEAK GRADIENT AND CLEAR SKIES LEADING TO A RATHER COLD
NIGHT. WHERE WINDS HAVE GONE CALM...TEMPS HAVE RAPIDLY FALLEN INTO
THE NEGATIVE NUMBERS. UPSTREAM OVER NORTHERN MN AREA OF
CLOUDS...MAINLY AT MID LEVELS MAKING RAPID PROGRESS TOWARDS
NORTHERN WI. CLOUDS ASSOCIATED WITH SIG WAA THAT IS EXPECTED TO
PASS THROUGH NORTHERN PORTION OF THE STATE THIS MORNING...EXITING
IN THE LATER AFTERNOON. SOME FLURRIES SEEN...THOUGH THIS IS
EXPECTED TO PASS NORTH OF STATE WITH DEEPER MOISTURE. LITTLE
CHANGE MADE TO MAX TEMP GRIDS TODAY WITH CLOUDS HELPING TO HOLD
BACK TEMPS TODAY.

INCREASING SW LOW LEVEL FLOW TONIGHT WITH 925 WINDS APPROACHING 35
KTS BY SUN MORNING...LEADING TO TEMPS SHOWING NON DIURNAL
TENDENCIES TONIGHT...LIKELY SEEING A RISING TREND AFTER MIDNIGHT.
BUFKIT CROSS SECTIONS ON BOTH GFS AND NAM SHOWING LOW LEVEL
STRATUS MOVING IN OVER AREA TONIGHT. AM HAVING HARD TIME BELIEVING GIVEN
LIMITED MOISTURE IN VICINITY. WILL NEGATE FOR MOST PART...WITH
THOUGHTS THAT THIS IS MORE PROBABLE SUN NIGHT AS MOISTURE SURGES
NORTH AHEAD OF LOW IN PLAINS.

850 TEMPS INCREASE TO ABOVE ZERO BY SUN MORNING...THOUGH STRONG
INVERSION IN PLACE WITH MODELS SHOWING MIXING LIMITED TO 1K FT OR
LESS. HAVE SIDED WITH COOLER GUIDANCE...SHAVING OFF A DEGREE OR TWO
FROM PREVIOUS MAX TEMP FORECAST.

.LONG TERM...SUNDAY NIGHT THROUGH FRIDAY.

MAIN FORECAST CONCERNS DURING THE PERIOD ARE PRECIPITATION
CHANCES.

THE WEATHER BECOMES MORE INTERESTING LATE SUNDAY NIGHT INTO THE
EARLY PART OF THE WORK WEEK. A SHORT WAVE ALOFT...FROM THE
SSW...WILL COMBINE WITH A COLD FRONT APPROACHING FROM THE
NORTHWEST TO BRING PRECIPITATION CHANCES BACK TO THE AREA. NOT
MUCH LIFT IS EXPECTED BUT MOISTURE WILL INCREASE AHEAD OF THE
FRONT AS WARM ADVECTION TAKES PLACE. HAVE A CHANCE OF RAIN ACROSS
THE SOUTHEAST HALF OF THE FORECAST AREA AND SNOW FOR THE
REST...BUT HAVE ALSO INCLUDED A MENTION OF DRIZZLE OR FREEZING
DRIZZLE DUE TO LACK OF STRONG LIFT. HAVE MORE SNOW THAN RAIN MENTIONED
BY MONDAY NIGHT BUT CONTINUED WITH A MENTION OF DRIZZLE OR
FREEZING DRIZZLE.

ONCE THE COLD FRONT PASSES SOUTHEAST OF THE AREA THERE SHOULD BE A
PERIOD OF DRY WEATHER BEFORE A MORE SIGNIFICANT SYSTEM APPROACHES
THE REGION FROM THE SOUTHWEST. MODELS SHOWED ENOUGH DIFFERENCES IN
TRACK AND TIMING THAT CONFIDENCE IS NOT THAT GREAT AT THIS POINT.
SOME PRECIPITATION TYPE ISSUES ARISE AGAIN BUT THE END OF THE WEEK
SHOULD BE COLD ENOUGH FOR JUST SNOW BEHIND THE SYSTEM
&&

.AVIATION...GOOD FLYING WEATHER TONIGHT THROUGH SATURDAY EVENING
WITH CLEAR SKIES TONIGHT AND INCREASING MIDDLE AND HIGH CLOUDS
SATURDAY.

RDM

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