AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MARQUETTE MI
1230 AM EST SUN DEC 14 2008
UPDATED FOR THE 06Z TAF ISSUANCE
.SYNOPSIS...
ATTN IS SQUARELY ON STRONG SHORTWAVE OVR PACIFIC NW INTO NRN ROCKY
MOUNTAINS. 12HR HEIGHT FALLS OVR 200M SPREADING OUT AHEAD OF THE
WAVE AND A 150+KT JET STREAK AT H3 IS DIGGING ALONG WRN PERIFERY OF
THE TROUGH. AS JET/HEIGHT FALLS MOVE INTO THE PLAINS THIS EVENING
SFC TROUGH OVR THE ROCKIES WILL STRENGTHEN INTO A 990MB SFC LOW.
THIS LOW LIFTS ACROSS WRN UPR MI ON SUNDAY...BRINGING A MIXED BAG OF
RAIN/FREEZING RAIN/SNOW TO UPR MI. EXPECTED TRACK OF SFC LOW FAVORS
PCPN IN FAR WRN TIER OF CWA TO REMAIN SNOW THROUGH THE EVENT.
&&
.SHORT TERM (TONIGHT AND SUNDAY)...
WARM AND MOIST SOUTHERLY FLOW CONTINUES ACROSS UPR LAKES. WARM FRONT
AT THE SFC HAS NOT QUITE MADE IT INTO UPR MI...BUT ITS CLOSE. SFC
TEMPS HAVE ALREADY CRACKED FREEZING MARK ALONG LK MICHIGAN...BUT ARE
STILL IN THE MID 20S OVR WRN AND CNTRL CWA. WARMING ALOFT WILL BRING
MIXED PCPN ISSUE INTO FCST LATER TONIGHT AND MORE SO ON SUNDAY. FOR
TONIGHT...MULTIPLE WAVES OF ISENTROPIC LIFT SHOULD ALLOW FOR PERIODS
OF LGT SNOW ACROSS CWA. EXCEPTION IS DOWNWIND OF LK MICHIGAN AS
NAM/LOCAL WRF SHOW TEMPS IN LOWEST 1KFT WARMING ABOVE FREEZING
INLAND AFT 06Z. DESPITE WARMING...GROUND TEMPS STILL REMAIN
COLD...AND THE RAIN IS ARRIVING DURING THE NIGHT. SO...THOUGHT IT
WOULD BE GOOD TO HAVE A MENTION OF FZRA OVR THE ECNTRL INTERIOR.
ELSEWHERE...SOUNDINGS INDICATE STEADIER PCPN TAPERS OFF AFT 06Z BUT
THERE IS STILL MOISTURE IN LOW-LEVELS WITH LIFT IN THE MOIST LAYER.
MENTION OF FZDZ SEEMS APPROPRIATE.
LATER TONIGHT TOWARD DAYBREAK ON SUN...WAVE OF DEEPER MOISTURE/PCPN
CURRENTLY OVR NRN IL MAKES ITS WAY INTO SRN CWA. PCPN IS SUPPORTED
BY ISENTROPIC LIFT ON 295K SFC (H8-H7) AS A RESULT OF CONTINUAL WARM
AIR ADVECTION. MIXING RATIOS FLIRT WITH 4G/KG BUT PERIOD OF LIFT
MOST LIKELY ENDS UP LESS THAN 6 HR IN DURATION. SOUNDINGS OVR WRN
HALF OF CWA SHOW A BRIEF PERIOD OF MODERATE SNOW (1-3 OR PERHAPS
2-4) INTO LATE MORNING...WHILE MORE OF A RAIN/SNOW MIX WITH
LINGERING FZRA IN THE INTERIOR PERSISTS IN THE EAST. HEAVIER PCPN
WILL BE OVR THE WRN CWA CLOSER TO THE INCOMING HEIGHT FALLS AND
SHARPENING INVERTED SFC TROUGH TIED TO THE SHORTWAVE TROUGH/LOW
PRESSURE SYSTEM LIFTING ACROSS THE CNTRL PLAINS.
SOUNDINGS OVR CNTRL CWA INDICATE 900MB-850MB WARM LAYER...WITH TEMPS
UP TO +2C...AFFECTING THE AREA AS SFC LOW REACHES JUST SW OF UPR MI
BY 00Z MON. DO EXPECT MOST AREAS EAST OF THE INVERTED TROUGH TO HAVE
A COMPLETE CHANGE TO RAIN BUT THROUGH EARLY AFTN THE INTERIOR WHERE
GROUND TEMPS ARE STILL BLO FREEZING COULD SEE SOME FZRA.
GOING ADVY FOR FAR WRN CWA LOOKS GOOD. PTYPE ON SUNDAY SHOULD REMAIN
MOSTLY SNOW WITH ACCUMS UP TO 5 INCHES DURING THE DAY. ALSO...WENT
AHEAD AND ISSUED WINTER WEATHER ADVY FOR AREAS TO THE EAST OF THE
GOING ADVY...BASICALLY THROUGH BARAGA AND IRON COUNTIES. IN THOSE
AREAS...EXPECT THE SNOW IN THE MORNING TO CHANGE TO FZRA AND
EVENTUALLY RAIN IN THE AFTN. DID NOT ISSUE THE ADVY FARTHER TO THE
EAST AS PCPN AMOUNTS ARE NOT TOO SIGNIFICANT.
.LONG TERM (SUN NIGHT THROUGH NEXT SATURDAY)...
PERIOD BEGINS WITH BROAD UPPER TROUGH OVER WRN CONUS AND STRONG SFC
LOW TRACKING INTO UPPER MI. PATH OF THE LOW HAS CONTINUED TO BE
CONSISTENT AND TRAVELING NE FROM WATERSMEET AT 00Z MON AND OVER ERN
LK SUP AT 06Z. INTENSITY OF THE LOW HAS COME INTO AGREEMENT...WITH
IT PASSING ACROSS UPPER MI AROUND 993MB. COLD AIR WILL QUICKLY MOVE
OVER THE AREA FROM W TO E ON SUN NIGHT...WITH -20C DROP AT H850 OVER
THE W BETWEEN 00Z AND 12Z MON. THIS WILL CREATE A QUICK TRANSITION
FROM RAIN TO SNOW ACROSS THE AREA. EXPECT PCPN THROUGH THE NIGHT
OVER THE WRN CWA...AS COLD AIR WRAPS AROUND THE LOW AND LK INFLUENCE
KICKS IN. ONLY HAVE A COUPLE OF INCHES OF ACCUMULATION OVERNIGHT IN
THE WRN TIER OF COUNTIES...DUE TO LIMITED QPF AS MOISTURE WRAPS
AROUND AND THE STRONGER WINDS BREAKING UP THE LARGER SNOWFLAKES AS
THEY COME DOWN. ADDED BLOWING SNOW OVER THE WRN CWA ALONG LK SUP
AFTER 06Z MON AND THROUGH 00Z TUES...AS STRONG WINDS COME OFF THE
LAKE AND 6HR PRESS RISE/FALL COUPLET MOVES THROUGH. FOR THE CNTRL
AND ERN CWA...MIGHT BE A PERIOD OF MIX PCPN AS DRY SLOT AND
SUBSIDENCE MOVES IN BEHIND THE COLD FRONT...BUT EXPECT MOST OF THE
PCPN TO BE DONE AT THAT TIME. DID LOWER POPS BEHIND THE FRONT OVER
THE S CNTRL CWA DUE TO PREVIOUSLY MENTIONED REASONS. END TIME FOR
THE ADVISORIES OVER THE WRN TIER OF COUNTIES SEEMS REASONABLE WITH
THE WINDS...BLOWING SNOW...AND SNOW FOR MON. TEMPS WILL STRUGGLE TO
RISE ON MON...WITH H850 TEMPS FALLING BETWEEN -28 TO -25 OVER THE W
AND LOW -20S OVER THE E BY THE AFTN. EXPECT THE HIGHS FOR THE DAY TO
BE AROUND DAYBREAK AND THEN DROP THROUGH THE DAY. THIS IS ALSO SHOWN
ON MAV/MET GUIDANCE AND ATTEMPTED TO FOLLOW FOR HOURLY TEMPS.
EXPECT LES TO CONTINUE ON MON NIGHT...WITH ONLY LIGHT ACCUMULATIONS
IN LOCATIONS FAVORED BY A WNW WIND. WINDS WINDS WILL BEGIN TO BACK
TO THE SW ON TUES AND PUSH THE LES BANDS OVER LK SUP. MON NIGHT
TEMPS SHOULD BE VERY COLD OVER INTERIOR W PART OF CWA. WITH LITTLE
TEMP RESPONSE ON MON AND COLD TEMPS ALOFT...EXPECT AREAS THAT CLEAR
OUT IN THE INTERIOR W AREA OF CWA TO DROP INTO THE TEENS BELOW ZERO.
KEPT TEMPS TUES COLD...IN THE TEENS...AS H850 TEMPS ARE STILL AROUND
-20 WEST TO -16 EAST...BEFORE WINDS BEGIN TO TURN TO THE SW AND
INCREASE DURING THE AFTN.
WAVE MOVING THROUGH UPPER RIDGE OVER WRN CAN AND AK COMPRESSES
TROUGH OVER WRN CONUS ON TUES. THIS WAVE WILL MOVE THROUGH THE UPPER
GREAT LKS ON TUES NIGHT AND EARLY WED...AND MERGE WITH WAVE COMING
OUT OF THE TROUGH OVER WRN CONUS. SOME DIFFERENCES IN THE HANDLING
OF THESE WAVES AND ASSOCIATED SFC FEATURES AT THIS TIME. GEM/ECMWF
SHOW A BROAD/WEAK AREA OF LOW PRESS DEVELOPING WITH THE WAVES OVER
THE GREAT LKS...WHILE THE GFS DEVELOPS A SLIGHTLY STRONGER AND
CLOSED OFF LOW TRACKING THROUGH THE OHIO VALLEY REGION. HAVE BUMPED
UP CHANCES ACROSS THE CWA FOR TUES NIGHT AND WED...SINCE MOST MODELS
SHOWING AT LEAST SOME PCPN AS THE WAVES MOVE THROUGH. JUST EXPECT A
COUPLE INCHES OF SNOW...AS THERE IS LITTLE MOISTURE TO DRAW
FROM...PWAT VALUES AROUND 0.2...AND DGZ NEAR THE SFC WITH H850 TEMPS
AROUND -18C. BEHIND THE WAVES...WEAK W TO NW WINDS ARE EXPECTED AS
ANOTHER HIGH MOVES OVER THE NRN PLAINS WED AND THURS. WITH H850
TEMPS REMAINING STEADY...EXPECT SOME LES TO DEVELOP ON WED AND THEN
GRADUALLY SHIFT OVER LK SUP ON THURS...AS WINDS BACK TO THE SW. ONLY
LIGHT ACCUMULATIONS EXPECTED DUE TO SIMILAR FEATURES MENTIONED
ABOVE. GFS/ECMWF ARE HINTING AT ANOTHER WAVE/LOW COMING OUT OF THE
WRN CONUS TROUGH FOR THURS NIGHT THROUGH FRI AND HAVE EXPANDED
CHANCE POPS ACROSS THE AREA TO ACCOUNT FOR THIS. TEMPS FOR THE
EXTENDED PERIOD WILL BE WELL BELOW NORMAL THROUGH THE FIRST HALF OF
THE WORK WEEK...BEFORE GRADUALLY MODERATING TO SLIGHTLY BELOW NORMAL
VALUES BY THE WEEKEND.
&&
.AVIATION (FOR THE 06Z TAF ISSUANCE)...
IFR CONDITIONS...IN TERMS OF VSBY AND CIGS...CONTINUE AT CMX AND SAW
OVERNIGHT AS WARMER/MOIST SOUTHWEST FLOW FLOWS OVER THE TOP OF
SHALLOW COOL LAYER AT THE SFC. EXPECT A MIX OF LGT SNOW/SNOW
GRAINS/FZDZ. VSBY WILL REMAIN LOW THOUGH DUE TO THE INCREASED LOW
LEVEL MOISTURE. PERIOD OF HEAVIER SNOW...VSBY LIFR OR VLIFR IS
POSSIBLE ON SUNDAY AT BOTH SITES. CONDITIONS WILL NOT CHANGE MUCH
AND WILL REMAIN LIFR WITH LOW CIGS AND VIS AT BOTH SITES. RAIN WILL
MOVE INTO SAW SUN MORNING.
&&
.MARINE (FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE)...
A LOW PRESSURE SYSTEM MOVING OUT OF LEE OF THE ROCKIES WILL TRAVEL
NE THROUGH THE PLAINS ON SUNDAY AND THEN ACROSS LAKE SUPERIOR ON
SUNDAY NIGHT. THIS WILL PRODUCE INCREASING SOUTHERLY WINDS OVER
EASTERN LAKE SUPERIOR AND NORTHEASTERLY WINDS OVER WESTERN LAKE
SUPERIOR TONIGHT. AS THE LOW MOVES INTO MN AND WI ON SUN...NORTHEAST
GALES TO 45 KNOTS ARE EXPECTED OVER THE WESTERN HALF OF LAKE
SUPERIOR. WINDS WILL TURN TO THE NORTHWEST SUNDAY NIGHT AND
MONDAY...AS THE LOW MOVES INTO CANADA. NORTHWEST WINDS ARE EXPECTED
TO DIMINISH MONDAY EVENING AND REMAIN BELOW 25 KNOTS THROUGH FRIDAY.

The national radar mosaic for the moment the first event began.
4 winter weather. Local standard time, as filed.
A spotter five miles northwest of Wakefield estimated four to six inches of snow in 12 hours. Some freezing rain was also reported.
A sloppy mix of wet snow and rain contributed to very slippery highways across the county on the 14th. One car slid into a guardrail on Highway 41. The observer in Watton reported two inches of wet snow in 12 hours.
The Marquette National Weather Service in Negaunee Township measured over 4.5 inches of wet snow in 14 hours. The mix of rain and snow contributed to slippery highways and a few minor accidents throughout the county on the 14th. The poor weather conditions also forced airlines to cancel flights in and out of K.I. Sawyer International Airport.
A wintry mix of wet snow...rain and freezing rain contributed to very slippery driving conditions in the hills of Houghton/Hancock as reported by WLUC-TV in Marquette.
