AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
418 AM CST TUE FEB 5 2008

.SHORT TERM...TODAY INTO WEDNESDAY

WATCHING TWO SYSTEMS FOR THIS PERIOD. SHORT WAVE SHIFTING EAST
THROUGH WESTERLIES OVER SOUTHERN CANADA AND UPPER LOW LIFTING OUT
OF THE SOUTHERN PLAINS. SOME DIFFERENCES IN NCEP MODELS WITH GFS
FASTER IN LIFTING OUT LOW...BRINGING PCPN FURTHER NORTH. NAM REMAINS
DRY FOR AREA...THOUGH HAS TRENDED A BIT FURTHER NORTH WITH THIS
RUN. BOTH MODELS SHOWING SOUTHERN/SOUTHEAST PORTION OF CWA UNDER
DYNAMICS OF EXITING JET MAX/COUPLED JET FEATURE TONIGHT. GFS
SHOWING AREA OF GOOD FRONTOGENETIC FORCING AT MID LEVELS AND WEAK
LLVL ADVECTION. WILL TREND WITH BLEND OF GFS/NAM AS SUGGESTED BY
NCEP LEANING TOWARDS PCPN EDGING FURTHER NORTH AS HAS BEEN THE
TREND THIS SEASON. BOTH CANADIAN AND ECMWF SUPPORT THIS. CONCERNED
THAT WILL HAVE SOME LAKE ENHANCEMENT/EFFECT LATER TONIGHT INTO WED
MORNING. LLVL WINDS FAIRLY WELL ALIGNED BY 00Z TONIGHT...WITH
DELTA TS DROPPING TO AROUND 10 OR 11 BY MORNING. CONFIDENT ENOUGH TO
GO WITH ADVISORY FOR FAR SOUTHEAST. WILL GO WITH TOTALS OF 1 TO 3
INCHES POSSIBLE FURTHER WEST AND NORTH. NORTHERN STREAM SHORT WAVE
TO SHUNT DEEPER MOISTURE TO THE SOUTH AND EAST...THUS WILL STAY
WITH VERY LOW CHANCE POPS FOR NORTH CENTRAL WI.

RIDGE AND DRIER/COLDER AIR MASS TO WORK IN WED WITH PCPN CHANCES
QUICKLY ENDING FROM NORTH TO SOUTH THROUGH THE DAY.

.LONG TERM...WED NGT THRU NXT MON. MAIN FCST CHALLENGES TO BE
SEVERAL CHCS FOR GENERALLY LGT SNOW AND DEPTH OF ARCTIC AIR SET TO
ARRIVE THIS WEEKEND.

WEAK RIDGING BOTH AT THE SFC AND ALOFT TO MOV ACROSS NE WI WED NGT
BRINGING PARTLY CLDY SKIES...LGT WNDS AND COLD TEMPS TO THE RGN.
DUE TO FRESH SNOW ON THE GROUND...PREFER TO LEAN ON THE COLDER MAV
GUID FOR MIN TEMPS WHICH WAS WELL-HANDLED BY THE PREV SHIFT. A
SHRTWV TROF/ACCOMPANYING SHEARED SHRTWV AND SFC TROF TO APPROACH
NE WI ON THU. CLDS WL QUICKLY INCREASE THU MORNING WITH A CHC OF
LGT SNOW ARRIVING BY THU AFTERNOON AS THE TROF PUSHES INTO THE
AREA. FORCING AND LIFT APR RATHER WEAK...THUS AM EXPECTING ONLY
LGT QPF AMTS. CURRENT THINKING IS THAT MOST LOCATIONS WOULD SEE AN
INCH OR LESS OF SNOW ACCUMULATION BY 00Z FRI. THE SW WNDS AHD OF
THIS SYSTEM SHOULD HELP BRING TEMPS INTO THE MID TO UPR 20S
THROUGHOUT NE WI.

WL NEED TO CARRY A SML CHC OF SNOW FOR ERN WI INTO THU EVENING AS
THE SYSTEM STILL IN THE PROCESS OF EXITING THE RGN. OTHERWISE...A
LACK OF DRY AIR OR SUBSIDENCE SHOULD KEEP CLDS HANGING AROUND THRU
THE REST OF THE NGT. THESE CLDS WL HELP HOLD TEMPS UP SOMEWHAT
WITH READINGS A GOOD 5 TO 10 DEGS WARMER THAN WED NGT. ATTN SHIFTS
TO THE NW WHERE MDLS INDICATE A FAST MOVG CLIPPER-TYPE AREA OF LOW
PRES MOVG ACROSS EXTREME SRN CANADA ON FRI. BEST DYNAMICS/FORCING
TO BE RELEGATED TO OUR NORTH...HOWEVER A TRAILING CDFNT EXTENDED
SW FROM THE SFC LOW IS PROGGED TO APPROACH NW WI BY 00Z SAT. SINCE
MSTR APRS TO BE RATHER SHALLOW...PREFER TO ONLY MENTION A SLGT CHC
FOR N-CNTRL WI AND DROP THE FLURRIES ELSEWHERE.

ANY LGT WAA PCPN AHD OF THE FIRST CDFNT IS FCST TO QUICKLY DEPART
THE AREA BY FRI EVENING...HOWEVER THE TRUE ARCTIC FNT IS THEN SET
TO SWEEP INTO WI LTR FRI NGT. BULK OF CAA/BAROCLINIC ZN PCPN LOCATED
BEHIND THE FNT SO PREV FCST OF BRINGING SNOW BACK TO N-CNTRL WI AFT
MIDNGT STILL LOOKS GOOD ATTM. THE MAIN UPR TROF WL THEN SWING ACROSS
THE WRN GREAT LKS ON SAT ACCOMPANIED BY A STG SHRTWV EMBEDDED IN THE
MEAN FLOW. MORE THAN ENUF FORCING AND LIFT TO WARRANT A CHC OF SNOW
SHWRS AND/OR FLURRIES OVR ALL OF NE WI ON SAT. TEMPS ON SAT WL BE
TRICKY DEPENDING ON EXACTLY WHERE THE ARCTIC FNT WL BE LOCATED. WE
COULD VERY EASILY HAVE MORNING HIGHS AND THEN WATCH TEMPS STEADILY
FALL THRU THE REST OF THE DAY.

CANADIAN HI PRES IS EXPECTED TO BUILD SE INTO THE NRN PLAINS/MIDWEST
SAT NGT AND INTO THE WRN GREAT LKS BY SUNDAY. NW WNDS AND 8H TEMPS
DOWN INTO THE -24 TO -28C RANGE SHOULD BRING LK EFFECT SNOW SHWR
POTENTIAL INTO FAR NRN WI (ESP VILAS CNTY) SAT NGT BEFORE TRAJS
BECOME UNFAVORABLE. HAVE LOWERED TEMPS FOR BOTH SAT NGT AND SUNDAY
A FEW DEGS...BUT IF THE GFS IS CORRECT...THESE READINGS WOULD NEED
TO BE DROPPED MUCH MORE IN LTR FCSTS. ANOTHER CLIPPER IS HINTED AT
BY THE MDLS EARLY NXT WEEK ALTHO THE MDLS ARE HAVING SIGNIFICANT
TIMING ISSUES DUE TO THE FAST W-NW FLOW MOVG ACROSS THE CONUS.
PREFER TO LEAVE THE CHC OF LGT SNOW GOING FOR SUNDAY NGT INTO MON
UNTIL THIS TIMING GETS BETTER RESOLVED.

.AVIATION...MFVR AND IFR CIGS EXPECTED THROUGH TODAY...WITH
CONDITIONS DETERIORATING SOUTH LATER THIS AFTERNOON AND EVENING WITH
SNOW DEVELOPING AHEAD OF WAVE LIFTING OUT OF PLAINS.

.GRB WATCHES/WARNINGS/ADVISORIES...
SNOW ADVISORY FROM 9 PM THIS EVENING TO 12 PM CST WEDNESDAY FOR
