The episode as NWS MQT wrote it up.
A winter storm developed over the Plains and tracked northeast into the Upper Great Lakes. The storm dropped widespread heavy snow across Upper Michigan from the evening of the 10th into the afternoon of the 12th. Blizzard conditions also occurred over the Keweenaw Peninsula on the morning of the 11th.
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 Apr 10, 7:15 PM EST, 45 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
815 PM EDT THU APR 10 2008
ADDED UPDATE SECTION AND UPDATED AVIATION DISCUSSION FOR 00Z TAFS
.UPDATE...
BAND OF MODERATE-HEAVY SNOW WITH UPSTREAM VSBY 1/2SM DOWN TO 1/4SM
PUSHING INTO SW UPR MI. THE BAND IS ASSOCIATED WITH INCREASING MID
LEVEL DEFORMATION AND INITIAL SURGE OF MID LEVEL FRONTOGENESIS. EVEN
A LIGHTNING STRIKE NEAR PARK FALLS WI IN THIS BAND. SINCE THE
HEAVIEST SNOW IS SHIFTING TO THE WEST OF UPR MI EXPECT A LULL AFTER
THIS BAND MOVES ACROSS BEFORE THE WIDESPREAD PCPN OVR SOUTHERN HALF
OF WI MOVES IN TOWARD MIDNIGHT.
UPDATED POPS/WX/SNOW AMOUNTS AS THE INITIAL BAND OF SNOW COMES IN
QUICKER.
DISCUSSION....
SHORT TERM...UP TO 00Z FRI...
UPPER AIR PATTERN CONSISTS OF A 500 MB CLOSED LOW ACROSS SW KS WITH
A STRONG 500 MB TROUGH ACROSS THE WESTERN HIGH PLAINS AND SHORTWAVE
RIDGING ACROSS THE UPPER GREAT LAKES. NAM TAKES THE 500 MB LOW
NORTHEAST TOWARDS THE AREA AND UP INTO THE UPPER GREAT LAKES REGION
ON FRI AND SAT WITH VERY SLOW MOVEMENT TO THE EAST.
LOOKING AT MODEL SOUNDINGS FROM THE GFS...KCMX...KSAW...KERY AND
KIWD ALL SHOW TEMPERATURES THROUGHOUT THE PROFILE REMAINING AT OR
BELOW FREEZING...SO ACCORDING TO THE GFS...PCPN TYPE SHOULD STAY ALL
SNOW. KISQ AND KESC SHOWS A WARM LAYER ALOFT AT 18Z FRI AROUND 800
MB OF 3C AND TEMPERATURES REMAINING ABOVE FREEZING FROM ABOUT 760 MB
TO 860 MB WITH THE SOUNDING REMAINING BELOW ZERO OTHERWISE. KMNM HAS
AN ELEVATED LAYER ABOVE FREEZING 06Z TONIGHT FROM 700 MB TO 850 MB
WITH WARMEST TEMPERATURES AROUND 3C AND THIS ELEVATED LAYER REMAINS
THROUGH 18Z FRI. KIMT HAS ELEVATED WARM LAYER AS WELL AT 18Z OF
2C...OTHERWISE THE SOUNDING REMAINS BELOW FREEZING THE WHOLE TIME.
IRON RIVER HAS ELEVATED LAYER OF 1C AT 18Z BUT VERY LITTLE LAYER OF
ABOUT 50 MB THICK FROM 750MB TO 800 MB. NAM FORECAST SOUNDINGS
SIMILAR TO THE GFS WITH THE WARM LAYER ALOFT AND WHO WOULD SEE SNOW
AND WHO WOULD SEE MIXED PCPN. WILL GO WITH MIXED PCPN FROM SOUTH OF
A LINE FROM IRON RIVER TO GERMFASK AS A FIRST GUESS. NORTH OF THAT
LINE WILL STAY ALL SNOW. FOLLOWED THIS REASONING FOR SNOW AMOUNTS
WITH DIFFERENT RATIOS USED WITH SLEET...RAIN AND SNOW MIXED IN WHICH
WILL LOWER LOWER THE SNOWFALL TOTALS. HAD A HARD TIME TRYING TO
REFLECT WHAT WAS GOING ON WITH THE MIXED PCPN INTO THE SNOW FORECAST
AND COULD HAVE SPEND ANOTHER COUPLE HOURS TRYING TO FINE TUNE
GRIDS...BUT THEN WOULD NOT HAVE TIME TO ISSUE PRODUCTS OR FORECAST
OTHER GRIDS. SNOW AMOUNTS...NOT CONFIDENT ENOUGH THAT I GOT THESE
RIGHT BUT BEST GUESS FOR STORM TOTALS IS UP TO TWO FEET...ESPECIALLY
IN THE HIGHER TERRAIN IN THE HURON MOUNTAINS AND UPSLOPE AREAS OF
MARQUETTE COUNTY WITH LESSER AMOUNTS NEAR THE SHORELINES AND THE
SOUTH AND EAST.
ONE MAJOR CHANGE I DID IS STARTED THE PCPN OFF AS SNOW TONIGHT AS
SOUNDINGS SHOWED AS SUCH WITH EVAPORATIVE COOLING TAKING PLACE WITH
SOME DRY AIR. THIS IS WHAT HAPPENED AT KGRB WHEN PCPN STARTED THIS
AFTERNOON...STARTED OFF BRIEFLY AS RAIN AND THEN QUICKLY CHANGED
OVER TO SNOW. WITH EALIER SNOW...SNOW AMOUNTS WILL BE UP. BLIZZARD
CONDITIONS WITH THE WINDS WILL BE A PROBLEM FOR LATE TONIGHT AND
FRI. DID NOT MAKE TOO MANY MAJOR CHANGES TO THE GOING FORECAST.
.LONG TERM...00Z SAT - 00Z MON
THE LOW WILL LIFT NORTHEAST INTO CENTRAL IOWA DRAGGING THE COLD
FRONT INTO MIDDLE MISSISSIPPI RIVER VALLEY FRIDAY NIGHT. ISENTROPIC
ASCENT AHEAD OF THE FRONT WILL CONTINUE TO DESTABILIZE THE LOW
LEVELS. USING A BLEND OF ECMWF AND GFS STILL SHOWS A .6-.7 INCH QPF
ACROSS THE AREA FRIDAY NIGHT. BUFKIT SUGGESTING A 8 TO 1 RATIO OVER
CENTRAL U.P. WITH A LITTLE HIGHER RATIO OVER THE WEST AND LESS OVER
THE EAST. LOOKING AT THE TEMPERATURE PROFILES...THIS SEEMS
REASONABLE FOR SNOW TOTALS. THIS WILL GIVE US TOTALS OF UP TO 6
INCHES OVER THE HIGHER TERRAIN OF NORTH CENTRAL U.P. AND 2 TO 3
INCHES ELSEWHERE DURING THIS PERIOD. THIS APPEARS TO BE IN LINE WITH
THE HPC GUIDANCE AS WELL.
THE LOW WILL DIG INTO SOUTHWEST LOWER MICHIGAN AS THE LONGWAVE
TROUGH SWEEPS INTO SOUTHEAST ONTARIO ON SATURDAY. Q-VECTOR ENERGY
WILL WEAKEN OVER THE AREA. AS THE LOW SWEEPS SOUTHEAST...DRIER AIR
WILL START TO INVADE THE FORECAST AREA FROM THE NORTHWEST
DIMINISHING THE CHANCES OF SNOW. GFS/ECMWF CONTINUE TO SHOW QPF OVER
THE AREA ON THE ORDER OF .4 TO .5 INCHES OVER U.P. KEEPING WITH THE
SAME RATIO...WILL GIVE SNOW TOTALS ON 1 TO 3 INCHES OVER THE AREA
WITH THE HEAVIEST OVER THE NORTHERN U.P.
THE LONGWAVE TROUGH WILL CONTINUE TO DOMINATE THE GREAT LAKES REGION
SATURDAY NIGHT INTO SUNDAY. A WEAK SHORTWAVE...WITH INCREASED
Q-VECTOR CONVERGENCE...SLIDING THROUGH THE TROUGH WILL ENTER INTO
THE FORECAST AREA. THE SURFACE RIDGE WILL SHIFT INTO NORTHERN
ONTARIO...THE UPPER MISSISSIPPI RIVER VALLEY AND THE FORECAST AREA.
THE AIR MASS WILL BE LITTLE DRY. THUS WILL KEEP A CHANCE OF SNOW
WILL CONTINUE OVER THE NORTHERN U.P. AS WINDS WILL REMAIN OUT OF THE
NORTH DRAWING SOME MOISTURE FROM THE LAKE.
THE CLOSED LOW OVER SOUTHERN QUEBEC WILL SLIDE EAST INTO THE
CANADIAN MARITIME SUNDAY NIGHT AND MONDAY. THE ACCOMPANYING LONGWAVE
TROUGH WILL EDGE INTO THE LOWER GREAT LAKES. A WEAK SHORTWAVE WILL
SWEEP THROUGH THE FORECAST AREA. THE RIDGE WILL MOVE INTO NORTHERN
ONTARIO AS ANOTHER LONGWAVE TROUGH EDGES INTO THE PACIFIC NORTHWEST.
THE SURFACE RIDGE WILL THEN NAVIGATE OVER THE UPPER GREAT LAKES. THE
LOWER GREAT LAKES LONGWAVE TROUGH WILL REACH THE EAST COAST ON
TUESDAY...WHILE WEST COAST TROUGH WANDERS INTO SOUTH CENTRAL CANADA
AND THE RIDGE WILL MOVE ACROSS UPPER MICHIGAN. THE SURFACE RIDGE
WILL REACH EASTERN CONUS AS A SURFACE LOW AND ACCOMPANYING COLD
FRONT TRACKS THROUGH THE NORTHERN PLAINS. ISENTROPIC ASCENT AHEAD OF
THE LOW WILL GENERATE A SOME RAIN SHOWERS OVER WESTERN LAKE SUPERIOR
LATE ON TUESDAY.
AS THE LOW AND ACCOMPANYING FRONTAL SYSTEM SWEEPS THROUGH THE
FORECAST AREA TUESDAY NIGHT AND WEDNESDAY IT WILL GENERATE A CHANCE
OF SOME SNOW. A WEAK RIDGE FOLLOWING THE FRONTAL SYSTEM WILL SWEEP
INTO THE AREA WEDNESDAY NIGHT AND CONTINUING INTO THURSDAY BRINGING
DRIER CONDITIONS TO THE AREA.

.AVIATION (FOR THE 00Z TAF ISSUANCE)...
SCT LOW CLOUDS TRIED TO FORM EARLIER...BUT DRY AIR ON AFTN TAMDAR
SOUNDING FM KSAW DID NOT ALLOW THIS MOISTURE TO FORM INTO A LOW
CLOUD DECK. CONDITIONS AT KSAW SHOULD LOWER THIS EVENING AS BAND
OF SNOW OVR WI ARRIVES. BAND OF SNOW STAYS OVR WESTERN AND SOUTHERN
UPR MI...SO KCMX SHOULD REMAIN VFR THIS EVENING. WINDS WILL CONTINUE
TO INCREASE. AFTER 06Z...CONDITIONS AT KCMX AND KSAW WILL RAPIDLY
DETEREORATE TO VERY LOW IFR IN SNOW AND BLOWING SNOW. LOW CONDITIONS
WILL CONTINUE ALL DAY AT KCMX BUT MAY IMPROVE SLIGHTLY AFT 18Z AT
KSAW...AT LEAST FOR A TIME...AS SNOW TRIES TO LIGHTEN SOME.
DIMINISHING TREND SHOULD BE BRIEF THOUGH AS SNOW IS EXPECTED TO
INCREASE AGAIN FRI EVENING.

.MARINE (FOR THE 4 PM LAKE SUPERIOR FORECAST ISSUANCE)...
A LONG LIVED GALE EVENT WILL CONTINUE THROUGH SATURDAY ACROSS THE
WATERS. STORM FORCE GUSTS ARE POSSIBLE ACROSS LAKE SUPERIOR
ESPECIALLY ACROSS THE FAR WEST WHICH WILL HAVE A STORM WARNING UP
WITH A FAVORED NE WIND FUNNELING DOWN LAKE SUPERIOR WHICH WILL HELP
WITH COASTAL CONVERGENCE AND THE TERRAIN WILL ACT TO FUNNEL THE WIND
AND ACCENTUATE THE WIND SPEEDS. PLAN ON WAVES AS HIGH AS 22 FEET AT
END OF FETCH AND ISSUED A LAKESHORE FLOOD STATEMENT FOR MARQUETTE
COUNTY TO ACCOUNT FOR THAT.
