TH

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
239 PM CST THU MAR 1 2012

.SHORT TERM...TONIGHT AND FRIDAY.

LATEST RUC ANALYSIS AND SATELLITE/RADAR IMAGERY SHOW LOW PRESSURE
MOVING OVER THE EASTERN GREAT LAKES...BUT WITH SURFACE TROUGHING
EXTENDING WEST INTO NORTHERN WISCONSIN.  THE COMBO OF WEAK CYCLONIC
FLOW AND THERMAL TROUGHING IN THE LOW LEVELS HAS LEAD TO A ROBUST
STRATUS DECK THAT HAS HELD FIRM THROUGH EARLY THIS AFTERNOON.  SOME
HOLES IN THE CLOUDS HAVE TRIED TO DEVELOP OVER THE LAKESHORE WITHOUT
MUCH LUCK.  MEANWHILE...PLENTY OF INCOMING CONCERNS UPSTREAM.
NORTHERN STREAM SHORTWAVE IS SLOWLY MOVING EAST OVER THE
MONTANA/N.D. BORDER WITH LIGHT SNOW SPREADING ACROSS N.D.  FARTHER
SOUTH...WEAK SHORTWAVE IMPULSES ARE MOVING WITHIN FAST SW FLOW OVER
THE CENTRAL PLAINS.  ONE DISTURBANCE IS PRODUCING LIGHT SNOW OVER NE
NEBRASKA AND NW IOWA.  FINALLY...THE STRONGEST SHORTWAVE IS RAPIDLY
MOVING EAST OVER UTAH/COLORADO...AND SNOW AMOUNTS/HEADLINES WITH
THIS FEATURE WILL BE THE MAIN FORECAST CONCERN.

TONIGHT...NORTHERN STREAM SHORTWAVE WILL MOVE ACROSS NORTH DAKOTA
INTO MINNESOTA AND PUSH AN UPPER LEVEL FRONT INTO NORTHWEST
WISCONSIN LATE TONIGHT.  FORCING IS PRETTY WEAK...BUT GUIDANCE IS
OPTIMISTIC ABOUT GENERATING LIGHT SNOW ALONG IT.  UPSTREAM OBS SNOW
THE POTENTIAL FOR LIGHT SNOW...SO WILL KEEP IT IN THE FORECAST AFTER
06Z.  MEANWHILE...RELATIVELY WEAKER SOUTHERN STREAM IMPULSES WILL
RACE NORTHEAST INTO THE WESTERN GREAT LAKES.  LIGHT SNOW OVER NE
NEBRASKA MAY MAKE A RUN AT CENTRAL OR EAST-CENTRAL WISCONSIN LATE AS
WELL.  CONFIDENCE NOT QUITE AS HIGH WITH THIS FEATURE AS THE ONE
FARTHER NORTH...SO WILL SHOW LOWER POPS.  NOT EXPECTING MUCH ACCUMS
WITH EITHER FEATURE THOUGH...PERHAPS A COUPLE TENTHS.
OTHERWISE...ANTICIPATE THE BACK EDGE OF THE LOW STRATUS WILL
ACCELERATE NORTHEAST OVER THE NORTHERN MISSISSIPPI VALLEY EARLY
TONIGHT.  LOW LEVEL WIND FIELDS BECOME WEAK SO THINK THE LOW
OVERCAST WILL HANG AROUND.  IF THEY DO CLEAR OVER CENTRAL AND
EAST-CENTRAL WISCONSIN (HIGHEST PROBABILITY)...MID AND HIGH CLOUDS
WILL KEEP THE SKIES OVERCAST.  LOWS IN THE MID 20S TO THE LOWER 30S.

FRIDAY...CENTRAL ROCKIES SHORTWAVE WILL BE MOVING ACROSS THE CENTRAL
PLAINS AND NORTHEAST OVER THE MID-MISSISSIPPI VALLEY.  IT WILL DRIVE
A RAPIDLY STRENGTHENING SURFACE LOW FROM SW MISSOURI TO NORTHEAST
INDIANA.  NUISANT SMALL PRECIP CHANCES WILL LINGER OVER N-C
WISCONSIN AND CENTRAL WISCONSIN IN THE MORNING BUT THE MAIN SHOW
WILL ARRIVE IN THE AFTERNOON AS THE SURFACE LOW MOVES OVER ILLINOIS
AND INDIANA. INCREASING UPPER DIVERGENCE IN THE LEFT FRONT QUAD OF A
JETSTREAK...AND STRONG FGEN CENTERED AROUND 700MB ON THE NW FLANK OF
THE SURFACE LOW WILL LEAD TO PRECIP SPREADING NORTHEAST OVER CENTRAL
AND NORTHEAST WISCONSIN MID-AFTERNOON ONWARD.  NEGATIVE EPV ABOVE
THIS FGEN LAYER WILL SUPPORT ENHANCED BANDING ACTIVITY WHICH COULD
LEAD TO LOCALLY HEAVIER SNOWFALL RATES.  SOME RAIN MAY MIX IN WITH
THE SNOW OVER THE FOX VALLEY AND LAKESHORE AREAS WHERE TEMPS WILL BE
IN THE MID 30S AS THE PRECIP ARRIVES.  BUT ONCE THE HEAVIER PRECIP
RATES MOVE IN...A TIGHTENING BAROCLINIC ZONE WILL LIKELY LEAD TO
RAPIDLY ACCUMULATING SNOW FOR THE EVENING COMMUTE.  COULD SEE A
QUICK 1-3 INCHES OF HEAVY SNOW FOR THE FOX VALLEY AND LAKESHORE BY
00Z SATURDAY WITH LESSER AMOUNTS TO THE NORTHWEST.  WILL HOIST A
WINTER STORM WATCH STARTING AT 3 PM FOR WINNEBAGO TO SOUTHERN
MARINETTE ON EAST.

.LONG TERM...FRI NGT THRU NXT THU. FAIRLY PROGRESSIVE MEAN FLOW
ACROSS THE COUNTRY AS ONE LONGWAVE TROF MOVES ACROSS THE ERN CONUS
THIS WEEKEND...TO BE FOLLOWED BY ANOTHER LONGWAVE TROF PUSHING
INTO THE WRN CONUS EARLY NXT WEEK. NE WI TO DEAL WITH INITIAL TROF
INTO THE WEEKEND...HOWEVER UPR RIDGING BETWEEN THE TWO TROFS WL
BRING A GOOD WARM-UP EARLY TO MID-WEEK. THE APPROACH OF A CDFNT
WED/THU WL BRING THE NXT BEST CHC OF SEEING WIDESPREAD PCPN.

MDLS CONT TO CONVERGE ON A STORM TRACK FROM TAKING A DEEPENING SFC
LOW ROUGHLY FROM SW LWR MI NEWD TO EXTREME SE ONTARIO FRI NGT.
ACCUMULATING SNOW WL CONT TO IMPACT PRIMARILY ERN WI WHERE AN ADDL
2 TO 4 INCHES IS PSBL DURING THE EVENING. CONVERSELY...WRN SECTIONS
OF THE FCST AREA (GENERALLY WEST OF HWY 51) WL BE LUCKY TO SEE AN
ADDL INCH OF NEW SNOW. STRONG CYCLONIC FLOW COMBINED WITH A SFC
TROF DROPPING SOUTH INTO WI WL KEEP AT LEAST A CHC OF SNOW SHWRS
ACROSS THE FCST AREA THRU THE OVRNGT PERIOD.

THE WEAK SFC TROF SAGS SWD TOWARD SRN WI ON SAT WITH A WEAKENING
CYCLONIC FLOW HANGING ON OVER THE WRN GREAT LKS. FURTHERMORE...THE
LONGWAVE TROF WL BE MOVING INTO THE REGION WITH SEVERAL EMBEDDED
SHORTWAVES PUSHING THRU WI. FINALLY...MID-LVL LAPSE RATES GET
PRETTY STEEP ADDING INSTABILITY TO THE ATMOSPHERE. ADD ALL THIS UP
AND WE ARE LOOKING AT A DECENT CHC OF SNOW SHWRS THROUGHOUT ALL OF
NE WI. WOULD NOT BE SURPRISED TO SEE A FEW LOCALLY HEAVIER SNOW
BURSTS WITH PERHAPS A QUICK ONE-HALF INCH TO AN INCH OF ACCUMULATION.
MAX TEMPS TO BE COOLER THAN PREV DAYS WITH READINGS TOPPING OUT IN
THE LWR TO MID 30S.

SNOW SHWRS SHOULD BECOME MORE ISOLATED IN NATURE SAT NGT AS THE SFC
TROF PULLS AWAY AND THE LOSS OF DAYTIME HEATING MINIMIZES THE
INSTABILITY. SKIES TO REMAIN MOSTLY CLOUDY THRU THE NGT...HOWEVER
ENUF COOL AIR TO HAVE SETTLED OVER THE REGION TO ALLOW TEMPS TO
DROP INTO THE TEENS NORTH/CENTRAL...NEAR 20 EAST-CENTRAL. THE
LONGWAVE TROF TO STILL BE SITUATED OVER THE GREAT LKS THRU SUNDAY...
THEREBY PROVIDING A MEAN NW FLOW ACROSS WI. A PROMINENT SHORTWAVE
IS FCST TO DIVE SE FROM MN TO NRN IL WITH EVEN A SEMBLENCE OF A WEAK
SFC LOW MOVING SE THRU IA. EXPECT TO SEE SCT SNOW SHWRS OVER MUCH OF
NE WI ON SUNDAY WITH MAX TEMPS ONLY REACHING THE MID 20S NORTH/
AROUND 30 CENTRAL/E-CENTRAL.

ANY SNOW SHWR ACTIVITY SHOULD DIMINISH SUNDAY EVENING AS THE
SHORTWAVE DIVES TOWARD THE OHIO RIVER VALLEY AND INSTABILITY
WEAKENS UPON SUNSET. AS HI PRES BUILDS ACROSS THE MIDWEST LATER
SUNDAY NGT...SKIES WL ATTEMPT TO BECOME PARTLY CLOUDY OVER AT LEAST
CENTRAL WI BRINGING ANOTHER COLD NGT TO THE FCST AREA. THE HI PRES
DRIFTS ACROSS WI ON MON AND WL BE SITUATED JUST TO OUR EAST BY 00Z
TUE. WINDS BACKING S-SW WL START TO TAP WARMER AIR TO OUR WEST...
BUT COOLS START TO THE DAY WL ONLY BRING MAX TEMPS ON MON INTO THE
30-35 DEG RANGE. AS THE HI PRES HEADS TOWARD THE ERN CONUS ON TUE...
A STRONG AREA OF LOW PRES WL BE MOVING ACROSS S-CENTRAL CANADA. A
TIGHT PRES GRADIENT TO EXIST ACROSS THE GREAT LKS...BRINGING
BLUSTERY CONDITIONS TO NE WI. THESE GUSTY S-SW WINDS WL ALSO DRAW
VERY MILD AIR INTO WI WITH 8H TEMPS CLIMBING TO NEAR +6C. DEPENDING
ON THE DEPTH OF THE SNOW COVER...MAX TEMPS SHOULD EASILY RISE INTO
THE 40S WITH ANY SNOW-FREE AREAS SURPASSING THE 50 DEG MARK.

THE NXT LONGWAVE TROF TO BE IN THE PROCESS OF PUSHING ACROSS THE
ROCKIES TUE NGT BEFORE REACHING THE NRN/CNTRL PLAINS ON WED.
PRECEDING THIS UPR TROF WL BE A CDFNT WHICH THE MDLS HAVE SOME
TIMING ISSUES WITH. LATEST TRENDS HAVE THIS FNT APPROACHING CENTRAL
WI BY WED AFTERNOON...THUS A NEED FOR CHC POPS ACROSS MOST OF NE
WI. ANOTHER MILD DAY WOULD HAVE ANY PCPN FALL AS RAIN WITH MAX
TEMPS TO RANGE FROM THE MID 40S NORTH TO AROUND 50 DEGS CENTRAL
AND EAST-CENTRAL WI. THE CDFNT DRIVES THRU MOST OF WI WED NGT WITH
A BAND OF LIGHT RAIN MIXING WITH AND CHANGING TO LIGHT SNOW AS
COOLER AIR ARRIVES BEHIND THE FNT. SOME DEBATE LINGERS AS TO
WHETHER THIS FNT WL BE ABLE TO CLEAR THE AREA BEFORE ANY SFC WAVES
CAN DEVELOP ON THE FNT TO SLOW ITS PROGRESS. HAVE USED A GENERAL
CONSENSUS FOR THU WHICH KEEPS THINGS DRY FOR NOW...BUT THU MAY
NEED TO BE RE-EVALUATED LATER AS THE 12Z ECMWF NOW DIGS AN UPR
TROF INTO THE CNTRL CONUS AND REVS UP A SFC LOW TOWARD CHICAGO.
&&

.AVIATION...CYCLONIC FLOW ACROSS MUCH OF THE GREAT LAKES REGION
KEEPING THE LOW STRATUS SOCKED IN AT THE TAF SITES.  NOT MUCH
IMPROVEMENT EXPECTED THIS AFTERNOON WITH DAYTIME HEATING.  COOLING
TONIGHT SHOULD LEAD TO LOWERING OF CIGS TO IFR LEVELS AT ALL TAF
SITES...WHICH COMPARES WELL TO THE MET GUIDANCE.  MAY SEE EVEN LOWER
CIGS OVER CENTRAL AND NORTH-CENTRAL WISCONSIN AS A SURFACE TROUGH
APPROACHES LATE TONIGHT.  A SMALL CHANCE OF LIGHT SNOW WITH THIS
TROUGH LATE TONIGHT INTO TOMORROW MORNING.  CIGS IMPROVE LATE
TOMORROW MORNING BACK TO MVFR BUT THEN WILL BE WATCHING FOR A
SIGNIFICANT WINTER STORM TO ARRIVE BY LATE AFTERNOON OVER THE FOX
VALLEY AND LAKE SHORE.
