AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
358 AM CST FRI DEC 14 2012

.SHORT TERM...TODAY THROUGH SATURDAY...SKY COVER AND TEMPERATURES
ARE THE MAIN CONCERN FOR TODAY...WITH PCPN TRENDS AND TYPE THE
DILEMMA FOR LATE TONIGHT INTO SATURDAY.

LOW CLOUDS HAVE FILTERED INTO NC AND PARTS OF FAR NE WI...IN THE
WAKE OF THE WEAK COLD FRONT THAT MOVED THROUGH THE FORECAST AREA.
PARTLY CLOUDY SKIES AND PATCHY FOG WERE OBSERVED ACROSS THE REST
OF GRB CWA...WITH FAIRLY THICK HIGH CLOUDS PREVENTING MORE
WIDESPREAD FOG FROM DEVELOPING. TEMPERATURES VARIED GREATLY ACROSS
THE RGN...RANGING FROM THE UPPER 20S WHERE LOW CLOUDS WERE PRESENT...
TO THE TEENS WHERE SKIES WERE PARTLY CLOUDY.

EXPECT THE LOW CLOUDS OVER NORTHERN WI TO ERODE ON THE EDGES THIS
MORNING...THEN GET ADVECTED NWWD AS SE WINDS DEVELOP THIS AFTERNOON.
PATCHES OF HIGH CLOUDS WILL CONTINUE TO STREAM ACROSS THE AREA...
LEADING TO PARTLY SUNNY CONDITIONS. DIDN'T MAKE ANY MAJOR ADJUSTMENTS
TO THE PREVIOUS MAX TEMP FCST...WHICH HAD HIGHS IN THE 30S.

HAVE DELAYED THE PCPN A LITTLE BIT TONIGHT...WITH CHC POPS ONLY
MAKING IT INTO OUR SW COUNTIES AFTER 09Z/SAT...WHEN SHORT-WAVE
ENERGY APPROACHES THE REGION. NUDGED MIN TEMPS A FEW DEGREES
FROM THE PREVIOUS FCST.

ON SATURDAY...THE MAIN SURGE OF PCPN IS EXPECTED TO MOVE INTO
GRB CWA...AS THE STRONG UPPER TROF...UPPER LEVEL DIVG AND WAA
ARRIVE. HAVE RAISED POPS TO 100 PERCENT ACROSS THE ENTIRE CWA
BY AFTERNOON. REMOVED ANY MENTION OF DZ/FZDZ AHEAD OF THE MAIN
PCPN BAND...AS RH TIMESECTIONS DON'T INDICATE ANY SIGNIFICANT
SATURATION IN THE LOWER ATMOSPHERE. HAVE SIDED CLOSELY WITH THE
ECMWF FOR PCPN TYPE...AS THIS MODEL IS PREFERRED BY HPC. THE
ECMWF SHOWED PRONOUNCED DYNAMIC/EVAPORATIVE COOLING IN THE
LOWER ATMOSPHERE AS THE MAIN PCPN BAND ARRIVES...WHICH MAKES
SENSE GIVEN THE ANTECEDENT DRY AIR. LOW-LEVEL TEMP/THICKNESS
PROGS SUGGEST MAINLY SNOW OVER NC/FAR NE WI...A MIX OF RAIN/SNOW
FROM CENTRAL INTO NE WI...AND MAINLY RAIN OVER THE FOX
VALLEY/LKSHR AREAS. EXPECT ACCUMS OF 2 TO 3 INCHES OVER NC/FAR NE
WI DURING THE DAY...WITH LESSER AMTS FARTHER SOUTH...AND LITTLE
OR NO ACCUM SE OF A LINE FROM WAUTOMA TO MARINETTE.

.LONG TERM...SATURDAY NIGHT THROUGH NEXT THURSDAY.

THE LATEST MEDIUM RANGE GUIDANCE CONTINUES TO SHOW SPLIT FLOW OVER
NORTH AMERICA THROUGH THE MIDDLE OF THE NEXT WEEK...THOUGH THE
SOUTHERN STREAM BECOMES DOMINANT ACROSS THE LOWER 48.  MEDIUM RANGE
MODELS CONTINUE TO STRUGGLE WITH THE DETAILS FOR THE SECOND HALF OF
THE WEEKEND.  BOTH THE NAM/GFS/GEM KEEP THE SURFACE LOW PARKED
ACROSS THE REGION LONGER THAN THE ECMWF...MOSTLY AS A RESULT OF
STRONGER SHORTWAVE ENERGY THAT FOLLOWS THE LEAD SHORTWAVE.  HPC PUTS
ITS SUPPORT INTO THE ECMWF...BUT CANNOT IGNORE THE OTHER MODELS.  SO
WILL USE A BLEND OF THE ECMWF/GFS FOR MUCH OF THIS FORECAST...WHICH
ARE ACTUALLY IN DECENT AGREEMENT IN THE LATER PERIODS.

SATURDAY NIGHT THROUGH SUNDAY NIGHT...BROAD LOW PRESSURE WILL BE
MOVING NORTHEAST ACROSS SOUTHWEST AND EAST CENTRAL WISCONSIN
SATURDAY NIGHT.  THOUGH THE MAJORITY OF THE LARGE-SCALE ASCENT WILL
HAVE PASSED TO THE EAST BY THE START OF THE PERIOD...PROGGED
SOUNDINGS REMAIN PRETTY SATURATED THROUGH THE 18Z SUNDAY...WHICH
SHOULD YIELD WIDESPREAD LIGHT PRECIP.  THERMAL PROFILES CONTINUE
THEIR WARMER TREND...AND WILL ONLY SHOW SNOW FOR THE NORTHERN PART OF
NORTH-CENTRAL WISCONSIN...RAIN FOR CENTRAL AND NORTH-CENTRAL
WISCONSIN...AND A MIX IN-BETWEEN.  SOME OF THE MIX WILL LIKELY START
CHANGING OVER TO SNOW LATE SATURDAY NIGHT OVER NORTH-CENTRAL
WISCONSIN AND ON SUNDAY OVER CENTRAL WISCONSIN AS WEAK COLD
ADVECTION SHIFTS EAST ACROSS THE STATE.  SNOW ACCUMULATIONS ACROSS
THE NORTH COULD SEE AN INCH OR INCH AND A HALF SATURDAY NIGHT AND
SUNDAY.  PRECIP WILL SLOWLY COME TO AN END FROM SW TO NE SUNDAY
AFTERNOON INTO SUNDAY EVENING.  STILL THINKING MOSTLY RAIN ACROSS
NORTHEAST WISCONSIN.  TEMPS WILL STICK IN THE 30S SATURDAY NIGHT AND
SUNDAY...THEN FALL INTO THE 20S SUNDAY NIGHT.

REST OF THE FORECAST...AFTER A POSSIBLE PERIOD OF DRY CONDITIONS...A
DECENT SHORTWAVE WILL BE PASSING OVER SOUTHERN WISCONSIN MONDAY
AFTERNOON.  MAY SEE LIGHT SNOW PASS OVER CENTRAL WISCONSIN FROM THIS
WAVE AND WILL LEAVE A SLIGHT CHANCE IN THE FORECAST.  THE WAVE
SHOULD BE EXITING BY THE START OF MONDAY EVENING...BUT PLENTY OF
MOISTURE IN THE LOW LEVELS WITHIN CYCLONIC FLOW SUGGESTS SCT-BKN
CLOUD COVER WILL LIKELY STICK AROUND THROUGH THE NIGHT.  HIGH
PRESSURE WILL MOVE ACROSS THE AREA TUESDAY AND TUESDAY NIGHT AND
SHOULD SEE THE CLOUDS DEPART OVER THIS PERIOD.  THE NEXT SYSTEM WILL
BE MOVING THROUGH DURING THE LATE WEDNESDAY THROUGH THURSDAY
PERIOD.  PTYPE MAY AGAIN BE A PROBLEM TO NAIL DOWN OVER EASTERN
WISCONSIN WITH THIS SYSTEM...BUT SHOULD HAVE ENOUGH COLD AIR AROUND
TO KEEP THE PTYPE AS ALL SNOW ACROSS THE NORTH.  PRECIP THEN EXITS
LATE THURSDAY INTO THURSDAY NIGHT.  TEMPERATURES NEAR NORMAL OVER
THE PERIOD.
&&

.AVIATION...FOR THE 06Z TAF ISSUANCE...WEAK PRESSURE GRADIENT OVER
REGION ASSOCIATED WITH WEAK COLD FRONT MOVING THROUGH NORTHERN
WI. LIGHT NORTH FLOW BEHIND FRONT...OFF SUPERIOR BRINGING SOME LOW
CLOUDS SOUTH. EXPECT WILL PERSIST THROUGH EARLY MORNING...LIMITING
FOG FORMATION FAR NORTH. AREA OF LOW CLOUDS EXPANDING QUICKER
SOUTH AND WEST...WITH MODELS INDICATING TRAPPED LOW LEVEL MOISTURE
THROUGH MUCH OF PERIOD. MAKES SENSE WITH WAA PATTERN FOR FRI AND
LINGERING SNOW/MOISTURE MELT. HAVE GONE PESSIMISTIC IN TAFS WITH
IFR CIGS REST OF TONIGHT...LIFTING TO MVFR ON FRI. INCOMING PCPN
WITH NEXT SYSTEM SLOWING DOWN WITH LAST FEW MODEL RUNS...HAVE
STAYED DRY THROUGH 15/06Z.
