The episode as NWS MQT wrote it up.
A clipper low pressure system moving through Wisconsin brought heavy lake enhanced snow to portions of Delta County on the 20th and 21st. The system also brought heavy lake effect snow to portions of Marquette County and the Keweenaw Peninsula. Winds gusting around 40 mph at times also caused considerable blowing of snow over the Keweenaw Peninsula.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Marquette, MI wrote its last area forecast discussion before the first event at Dec 20, 7:00 PM EST, 30 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MARQUETTE MI
700 PM EST SAT DEC 20 2008
UPDATED AVIATION SECTION FOR 00Z TAFS
.SYNOPSIS...
WATER VAPOR IMAGE AND RUC SHOWING A CLOSED LOW OVER NORTHWEST NORTH
DAKOTA...PUSHING A RIDGE OVER WESTERN ONTARIO AND THE UPPER GREAT
LAKES REGIONS. WEAK SHORTWAVES ARE BEING EJECTED OUT AHEAD OF THIS
LOW AND ARE OVER MANITOBA AND MINNESOTA. SURFACE ANALYSIS DEPICTS AN
INVERTED TROUGH STRETCHING FROM WESTERN IOWA NORTH INTO SOUTHEAST
MANITOBA. THIS TROUGH IS SEPARATING A RIDGE OVER EASTERN ONTARIO
FROM A HIGH OVER SOUTHWEST CANADA. ANOTHER SIGNIFICANT LOW IS OVER
THE MIDDLE MISSISSIPPI RIVER VALLEY. A STATIONARY FRONT STRETCHES
EAST FROM THIS LOW ACROSS THE SOUTHEASTERN STATES.
&&
.SHORT TERM...TONIGHT AND SUNDAY.
STRONG LIFT PER 700-500MB Q-VECTOR DIVERGENCE AND DEEP MOISTURE
THROUGH 20KFT THIS EVENING WILL ALLOW FOR 3 TO 4 INCHES OF SYNOPTIC
SNOW TO FALL TONIGHT AS INVERTED TROUGH SHIFTS INTO FORECAST AREA
AFTER 00Z. MAIN SNOW WONT ARRIVE UNTIL AFT 00Z. A SURFACE LOW
EJECTING OUT OF TEXAS THIS AFTERNOON WILL MERGE WITH THE TROUGH OVER
THE LOWER GREAT LAKES SUNDAY MORNING. AS THIS HAPPENS THE RESULTING
NORTHEASTERLY FLOW WILL ALLOW FOR HEAVY LES TO DEVELOP OVER NORTH
CENTRAL AND WESTERN UPPER MICHIGAN. WINTER STORM WARNINGS REMAIN IN
EFFECT FOR GOGEBIC/ONTONAGON/MARQUETTE/ALGER. ADVISORIES WILL KEEP
ELSEWHERE AS NOT ENOUGH CONFIDENCE IN REACHING WARNING CRITERIA.
TONIGHT THROUGH SUNDAY UP TO 8 INCHES OR MORE OF LES MAY FALL ACROSS
THE HIGHER TERRAIN OF MARQUETTE COUNTY...AREAS OF KEWEENAW COUNTY
AND INTO WESTERN GOGEBIC/ONTONAGON COUNTIES. THIS IS FURTHER
SUPPORTED BY THE LOCAL WRF MODEL. CONCERN ABOUT POSSIBLE LAKE
ENHANCED SNOW SHOWERS OVER MENOMINEE COUNTY...FOR POSSIBLE NEED FOR
WARNING. HOWEVER...WRF/NAM12 SHOWING WINDS BACKING NORTH SHORTLY
AFTER SUNRISE OVER SOUTHERN COUNTIES...DRIER AIR ADVECTING IN...AND
LACK OF TERRAIN SUPPORT OF LES. THUS WILL STAY WITH THE CURRENT
ADVISORIES FOR THAT AREA TOO. AFTER COORDINATED WITH GRB DECIDED TO
STAY WITH THE ADVISORY FOR NOW.
&&
.LONG TERM...SUNDAY NIGHT THROUGH SATURDAY.
SUN NIGHT...EXPECT TRANSITION FROM LAKE ENHANCED TO LAKE EFFECT SNOW
WITH CONTINUED VERY FAVORABLE SNOW GROWTH PARAMETERS WITH GOOD
UPWARD MOTION IN THE DGZ THROUGH 06Z/MON. EVEN THOUGH SNOW/WATER
RATIOS SHOULD BE AOA 30/1 DURING THE EVENING...WITH CONTINUED WINDY
CONDITIONS...FRACTURING AND DRIFTING SHOULD REDUCE ACTUAL/OBSERVED
SNOW TOTALS. NEVERTHELESS...ADDITIONAL AMOUNTS IN THE 2 TO 6 INCH
RANGE ARE EXPECTED FOR N WIND FAVORED SNOWBELTS...WITH THE GREATEST
AMOUNTS IN THE HIGHER TERRAIN WHERE STRONG UPSLOPE LIFT WILL OCCUR.
OVERNIGHT...WITH BACKING WINDS...LOWERING INVERSION HEIGHTS/ EXIT OF
DEEPER MOISTURE...SNOWFALL RATES WILL TAPER OFF AND LES SHOULD SHIFT
TOWARD NW FLOW FAVORED AREAS. BLOWING SNOW SHOULD ALSO SUBSIDE
OVERNIGHT AS THE GRADIENT WEAKENS IN THE WAKE OF THE DEPARTING LOW.
AS WINDS BACK TO WRLY BY MIDDAY MON...LES WILL SHIFT INTO
THE KEWEENAW AND FAR NE UPPER MI WHILE RELATIVELY TRANQUIL WEATHER
PREVAILS ACROSS THE REST OF THE CWA. BEFORE CLOUDS THICKEN MON
NIGHT IN ADVANCE OF THE NEXT SHRTWV...TEMPS MAY PLUMMET CLOSER TO
LOWER NAM GUIDANCE VALUES NEAR -10F WELL INLAND.
TUE...MDLS WERE IN GOOD AGREEMENT WITH THE NEXT MID LEVEL AND SFC
TROUGH THAT WILL MOVE THROUGH THE REGION BRINGING ANOTHER ROUND OF
SNOW. MDLS TEMP/UVV/RH PROFILE SUGGEST SNOW/WATER MAY BE RELATIVELY
LOW WITH BEST LIFT ABOVE THE DGZ. SO WITH QPF VALUES IN THE 0.10 TO
0.20 RANGE AND SNOW/WATER RATIOS NEAR 15/1 ACCUMULATIONS MAINLY IN
THE 1 TO 3 INCH RANGE WOULD BE EXPECTED.
WED...SIGNIFICANT UNCERTAINTY REMAINS WITH THE POTENTIAL FOR ANOTHER
STRONGER SHRTWV AND SFC LOW DEVELOPMENT. THE 12Z ECMWF AND UKMET
FAVORED POTENTIAL FOR HEAVIER SNOW WITH THIS FEATURE WHILE THE GFS
AND CMC DID NOT. IF THE EURO MODELS VERIFY...ANOTHER HEAVY
SNOW EVENT WOULD BE EXPECTED WITH FAVORABLE SCENARIO FOR LAKE
ENHANCED SNOW IN N CNTRL UPPER MI.
THU-SAT...THE FCST GENERALLY FOLLOWED THE HPC PREFERRED ECMWF/CMC
MDLS SCENARIO WHICH ALSO HAD DECENT SUPPORT FROM THE 12Z GFS
ENSEMBLES. THE 06Z/12Z WAS AN OUTLIER IN BRINGING A WEAKER NRN
STREAM SYSTEM THROUGH THE NRN TIER AND DELAYING THE EJECTION OF A
STRONGER SHRTWV FROM THE SW CONUS. SO...WITH A SW FLOW PATTERN AND
STRONGER SE CONUS RIDGE...A SHRTWV AND SFC LOW TRACK THROUGH OR WEST
OF CNTRL UPPER MI COULD BRING POTENTIAL FOR MIXED PCPN
(SN/FZRA/PL/RA) AND A BRIEF WARMUP AOA FREEZING BY LATE FRI.
&&
.AVIATION (FOR THE 00Z TAF ISSUANCE)...
SNOW IS SPREADING INTO THE SOUTHERN PORTION OF UPPER MICHIGAN AS
UPPER DISTURBANCE AND SURFACE TROUGH PUSH INTO THE AREA. EXPECT LGT
SNOW...MOSTLY IFR VSBY/CIGS...TO START UP AT BOTH SITES BY MIDNIGHT.
PERIOD OF HEAVIER SNOW/POTENTIAL VLIFR CONDITIONS DEVELOPS LATE
TONIGHT AT CMX AS THE SFC TROUGH SHIFTS THROUGH...THEN BY LATE
SUNDAY MORNING AT SAW. IN THE WAKE OF THE HEAVY SNOW THROUGH SUNDAY
AFTN...EXPECT VLIFR/LIFR CONDITIONS AT BOTH SITE DUE TO LK EFFECT
SNOW...STRONG NRLY WINDS GUSTING TO 35 KNOTS...AND SIGNIFICANT
BLOWING SNOW.
&&
.MARINE (FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE)...
THE WINDS ON LAKE SUPERIOR WILL INCREASE TONIGHT OUT OF THE
NORTHEAST. THIS IS DUE TO INTERACTION BETWEEN THE RIDGE OF HIGH
PRESSURE REMAINING OVER NORTHERN ONTARIO...AND A LOW PRESSURE OVER
THE OHIO RIVER VALLEY. WINDS SHOULD INCREASE FURTHER ON SUNDAY TO
NORTH WINDS 25 TO 30 KNOTS WITH FREQUENT GALE FORCE GUSTS TO 35 OR
40 KT AS THE LOW CONTINUES TO DEEPEN AND COLD AIR RUSHES SOUTH OUT
OF CANADA. THIS COLD AIR WILL ALSO HELP PRODUCE HEAVY FREEZING
SPRAY. THE WINDS WILL GRADUALLY DIMINISH SUNDAY NIGHT AND GALE FORCE
GUSTS WILL DIMINISH AS THE LOW PULLS AWAY. THE HIGH PRESSURE RIDGE
WILL CROSS UPPER MICHIGAN LATE MONDAY INTO MONDAY NIGHT...BUT WINDS
ON SUPERIOR SHOULD STILL STAY WEST TO SOUTHWEST AT 15 TO 30 KNOTS. A
LOW PRESSURE SYSTEM WILL DEVELOP OVER THE CENTRAL PLAINS ON
TUESDAY AND MOVE INTO THE UPPER GREAT LAKES TUESDAY NIGHT AND
WEDNESDAY. WINDS SHOULD STAY BELOW GALES CRITERIA WITH THIS
SYSTEM...THOUGH THE SOUTHERLY WINDS AHEAD OF IT ON TUESDAY AND THE
NORTHWEST WINDS BEHIND ON IT ON WEDNESDAY WILL CONTINUE TO RANGE
FROM 15 TO 30 KNOTS.
