The episode as NWS MQT wrote it up.
A strong upper disturbance from south central Canada produced moderate to heavy lake enhanced snow over portions of northwest and north central Upper Michigan from the 14th into the 16th.
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 14, 6:26 AM EST, 2 hours 34 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MARQUETTE MI 626 AM EST SAT DEC 14 2013 .SHORT TERM...(TODAY AND TONIGHT) ISSUED AT 503 AM EST SAT DEC 14 2013 WV IMAGERY AND RAP ANALYSIS SHOW A LONG WAVE TROUGH OVER THE CENTRAL CONUS...WITH MUCH OF THE ENERGY IN THE SOUTHERN STREAM MOVING THROUGH THE SOUTHERN THIRD OF THE CONUS. CLOSER TO THE UPPER GREAT LAKES...A SHORTWAVE IS CURRENTLY TRACKING THROUGH SOUTHERN MANITOBA AND INTO NORTHERN MINNESOTA AT THIS TIME...WITH A BROAD AREA OF MOISTURE AHEAD OF THIS WAVE IN MN/WI/MI. AT THE SURFACE...A ELONGATED AREA OF 1034MB HIGH PRESSURE STRETCHES FROM LAKE WINNIPEG EAST-SOUTHEAST INTO SOUTHWEST QUEBEC...WHILE A TROUGH STRETCHES NORTHEAST INTO SOUTHERN WISCONSIN FROM A 1007MB LOW IN NORTH CENTRAL TEXAS. THE FORCING FROM THE SHORTWAVE AND INCREASED MOISTURE AHEAD OF IT HAS LED TO -SHSN OVER MINNESOTA OVER THE LAST SEVERAL HOURS AND THEY HAVE EXPANDED EAST INTO WESTERN WISCONSIN. CLOSER TO THE U.P. 850MB TEMPS OF -17 TO -20C OVER THE CWA HAS COMBINED WITH LIGHT NORTHEAST TO EASTERLY FLOW TO LEAD TO LIGHT LAKE EFFECT SNOW SHOWERS OVER SOUTH CENTRAL LAKE SUPERIOR. IT HAS FINALLY STARTED TO PUSH TO THE NORTHEAST AS THE LOW LEVEL WINDS HAVE SWITCHED TO THE SOUTH. INVERSION HEIGHTS OF 3-4KFT ON 00Z KINL SOUNDING AND 08Z KMQT VAD PROFILE ARE LIKELY THE MAIN LIMITING FACTOR TO THE SNOW OVERNIGHT...IN ADDITION TO THE VARIABLE LOW LEVEL FLOW. FARTHER SOUTH...LAKE ENHANCED SNOWFALL CONTINUES OFF LAKE MICHIGAN IN EAST CENTRAL AND PARTS OF NORTHEAST WISCONSIN. THERE WAS A STRONGER BAND AFFECTING OCONTO EARLIER IN THE NIGHT...BUT IT HAS SINCE WEAKENED. THERE ARE SOME HINTS THAT THE LAKE EFFECT IS NEARING MENOMINEE...BUT VISIBILITIES THERE ARE STILL 10SM. MUCH OF THE FORECAST FOR THE SHORT TERM WILL FOCUS ON THE SHORTWAVE AND LAKE EFFECT/ENHANCED SNOWFALL UNDER VEERING LOW LEVEL WINDS TO THE SOUTHEAST THROUGH THE EVENING. AS THE SHORTWAVE SHIFTS INTO WISCONSIN AND UPPER MICHIGAN THIS AFTERNOON...A INVERTED TROUGH WILL DEVELOP NORTHWEST FROM THE LOW MOVING INTO THE MID ATLANTIC STATES. 00Z KINL SOUNDING FAIRLY REPRESENTATIVE OF THE LIMITED MOISTURE IN LOWER LEVELS ROTATING AROUND THE HIGH (VERY DRY BETWEEN 940-700MB)...BUT EXPECT THAT TO GIVEWAY FROM SOUTHWEST TO NORTHEAST LATE THIS MORNING AND CONTINUE INTO THE AFTERNOON. ALREADY FAIRLY MOIST ON THE 00Z KGRB SOUNDING AND WITH THAT CLOSE PROXIMITY AND LIGHT NORTHEASTERLY PUSH AROUND THE HIGH...THE DRIER AIR SHOULD GIVE AWAY FAIRLY EASILY. FORCING FROM THE SHORTWAVE AND INVERTED TROUGH WILL DEVELOP LIGHT SNOW ACROSS MUCH OF THE AREA LATE THIS MORNING BEFORE DIMINISHING FROM WEST TO EAST THROUGH THE LATE AFTERNOON AND EVENING HOURS. FOCUS TURNS TO LAKE EFFECT/ENHANCED SNOWFALL. FIRST...THE SNOW OVER SOUTH CENTRAL LAKE SUPERIOR SHOULD CONTINUE TO DRIFT NORTHWEST THIS MORNING AND BRIEFLY CROSS THE KEWEENAW PENINSULA BEFORE MOVING BACK INTO LAKE SUPERIOR. THE MAIN AREA OF CONCERN IS FOR LAKE ENHANCED SNOWFALL ALONG THE BAY OF GREEN BAY. INDICATIONS ARE THERE FROM THE MODELS AND THE DELTA-T VALUES OF 18 TO 21 SUPPORT IT...BUT HIGHER RESOLUTION MODELS WHICH TRADITIONALLY OVER DO QPF ARE STRUGGLING TO PUT OUT ANY SIGNIFICANT VALUES OVER SOUTHERN MENOMINEE AND SOUTHEAST DELTA COUNTIES TODAY. HAVE A FEELING THAT THE STRUGGLE TO PUT OUT ANY DECENT QPF IS RELATED TO THE LOW LEVEL SHEAR INDICATED BY THE MODELS. THIS CAN BE SEEN AT THE PRESENT TIME IN EAST CENTRAL WISCONSIN WHERE WINDS ARE PREDOMINATELY EASTERLY IN THE LOWER LEVELS AND LAKE ENHANCEMENT IS OCCURRING. BUT FARTHER NORTH ACROSS THE BAY OF GREEN BAY...THE DRIER AIR COMBINED WITH WINDS VARYING IN DIRECTION DEPENDING ON LEVEL (850MB VEERING SOUTHEAST...925MB STAYING MAINLY EASTERLY...AND SURFACE WINDS NORTHEASTERLY) HAS BEEN LIMITING DEVELOPMENT THUS FAR. THIS WILL LIKELY CONTINUE THROUGH THE AFTERNOON UNTIL THE TROUGH DEVELOPS ACROSS THE AREA AND FOCUSES WINDS OUT OF THE SOUTHEASTERLY DIRECTION THIS EVENING. AM WONDERING IF THIS SHEAR WILL BE ENOUGH TO LIMIT ANY REAL STRONG LAKE ENHANCED BANDS. IN ADDITION...INVERSION HEIGHTS AROUND MENOMINEE THIS MORNING ARE AROUND 5-6KFT AND REMAINS THROUGH MUCH OF TODAY...LIKELY LIMITING STRONG ENHANCEMENT AND HIGHER TOTALS. THEY ARE A LITTLE HIGHER AROUND ESCANABA (6-7KFT THIS AFTERNOON/EVENING) AND WHEN COMBINED WITH THE MORE UNIFORM FLOW THIS EVENING...THINK THAT IS WHEN THEY WILL HAVE THE BEST OPPORTUNITY FOR MODERATE SNOWFALL. ON THE POSITIVE SIDE...MUCH OF THE LAKE ENHANCED FORCING IS IN OR JUST BELOW THE DGZ AND ALLOW FOR SNOW RATIOS TO BE HIGHER AND AROUND 20 TO 1. UNFORTUNATELY...DEALING WITH AROUND 20-1 SNOW RATIOS MAKES FOR A DIFFICULT TIME ON PINNING DOWN AMOUNTS ON THESE LOWER END QPF AMOUNTS. MODEL COBB SNOW AMOUNTS ARE ALL OVER THE BOARD WITH 12Z NAM FOR KESC GIVING AROUND 3.5-4IN AND OUR LOCAL 00Z WRF-ARW HAS 3-3.8IN...WHILE THE 08Z RAP IS GIVING 1.3IN THROUGH 02Z. 03Z SREF MEAN HAS 2.3-3.0 AND THINK THAT IS A REASONABLE COMPROMISE. AMOUNTS FOR KMNM HAVE A SIMILAR RANGE...WITH THE HIGHEST AMOUNTS FROM THE MODELS OF 4-5INCHES...BUT THOSE RUNS HAD 2IN OF ACCUMULATION ALREADY EVEN THOUGH IT HASN/T EVEN STARTED SNOWING. THEREFORE...OPTED TO LOWER AMOUNTS ABOUT AN INCH AND MAY NEED TO DO MORE IF THE SNOW STRUGGLES TO DEVELOP THIS MORNING. STILL THINK THE HIGHEST AMOUNTS WILL BE OVER THE GARDEN PENINSULA...WHERE AMOUNTS COULD REACH 5 INCHES. OVERALL VERY UNCERTAIN ON SNOWFALL AMOUNTS FOR MENOMINEE AND DELTA COUNTIES TODAY...LARGELY DUE TO THE LOW LEVEL SHEAR THAT LOOKS LIKE IT WILL OCCUR. A LITTLE MORE CONFIDENCE IN PORTIONS OF DELTA AS WINDS BECOME MORE FAVORABLE THIS EVENING AND THERE IS LESS SHEAR...BUT EVEN THEN THE BANDS WILL LIKELY BE MOVING ENOUGH TO THE EAST TO LIMIT SIGNIFICANT ACCUMULATIONS. THEREFORE...WILL KEEP THE ADVISORY GOING FOR NOW (WITH WEAKER WORDING AND GREATER RANGE IN TOTALS TO SHOW UNCERTAINTY) SINCE THEY SHOULD SEE SOME SNOW AND ALLOW THE DAY SHIFT TO ASSESS THE SITUATION THROUGH THE MORNING. WITH THE UNCERTAINTY...DID NOT EXPAND ADVISORY TO SOUTHERN SCHOOLCRAFT FOR TONIGHT EVEN THOUGH THERE TOTALS ARE IN THE SAME RANGE AS SOUTHERN DELTA COUNTY. A SURFACE LOW LOOKS TO DEVELOP ALONG THE SURFACE TROUGH OVER NORTHERN LAKE SUPERIOR TONIGHT AS A SECONDARY AND STRONGER SHORTWAVE DROPS OVER LAKE SUPERIOR. THE FLOW AROUND THE LOW WILL KEEP MUCH OF THE LAKE EFFECT AWAY FROM THE LAKE SUPERIOR SHORELINES THIS EVENING...BEFORE WINDS SHIFT TO THE WEST-NORTHWEST OVER THE WESTERN LAKE OVERNIGHT WITH THE LOW MOVING INTO THE EASTERN LAKE. THEREFORE...SHOULD SEE LAKE EFFECT INCREASING OVER THE WESTERN HALF OF THE CWA OVERNIGHT WITH THAT WINDSHIFT AND THE INTENSIFYING LOW OVER THE NORTHERN/EASTERN LAKE. INVERSION HEIGHTS DO LOOK TO IMPROVE TO AROUND 10KFT OVER THE WESTERN LAKE OVERNIGHT AND WITH THE HELP OF THE ADDITIONAL MOISTENING TODAY FROM THE SURFACE TROUGH...THAT AREA SHOULD BE ABLE TO REALIZE THOSE FAIRLY HIGH INVERSION HEIGHTS. 850MB TEMPS FALL FROM -16C AT 06Z TO -20C BY 12Z SUNDAY...SO LAKE INSTABILITY IS PRESENT AND BUFKIT SOUNDINGS ARE SHOWING LAKE INDUCED CAPES IN THE 400-600 J/KG RANGE. IN ADDITION...THE EXTRA FORCING FROM THE SHORTWAVE (INCREASING MID LEVEL Q-VECTOR CONVERGENCE) WILL PRODUCE A CONDUCIVE PERIOD FOR LAKE EFFECT SNOWFALL. THUS...WOULD EXPECT THERE TO BE A FAIRLY DECENT BURST OF SNOW AFTER ABOUT 06Z FROM THE PORKIES UP THROUGH THE KEWEENAW PENINSULA AS THE WINDS SHIFT TO THE WNW. HIGH RESOLUTION MODELS AGREE FAIRLY WELL WITH THIS TIMING AND WILL BUMP POPS UP TO 100 PERCENT IN THOSE AREAS OVERNIGHT. WITH MUCH OF THE FORCING RIGHT WITHIN AND A LITTLE ABOVE THE DGZ...SHOULD SEE FAIRLY DECENT SNOW RATIOS (AROUND 20-22 TO 1) AND WOULD EXPECT AT LEAST OF COUPLE HOUR PERIOD OF 1 IN/HR SNOWFALL AFTER 06Z IN SOME LOCATIONS. THEREFORE...HAVE TRENDED THE SNOWFALL FORECAST UP A LITTLE BIT WITH A GENERAL 1-3 INCH AMOUNTS AND HAVE THE HIGHEST VALUES OVER THE HIGHER TERRAIN FROM THE PORKIES THROUGH THE KEWEENAW. OVER THE REST OF THE CWA...WINDS WILL BE SHIFTING FROM SOUTH-SOUTHEAST TO WESTERLY AS THE LOW MOVES TO THE EAST THROUGH THE NIGHT. EXPECT THE ONGOING LAKE EFFECT OFF LAKE MICHIGAN TO FOLLOW THAT EASTWARD PUSH THROUGH THE NIGHT AND LARGELY INFLUENCING DELTA COUNTY IN THE EVENING AND THEN SCHOOLCRAFT AND SOUTHERN LUCE COUNTIES DURING THE OVERNIGHT HOURS. THE EXPECTED EASTWARD MOVEMENT OF THE LAKE ENHANCED SNOWFALL SHOULD LIMIT THE SNOWFALL AMOUNTS OVER MOST OF THOSE AREAS TO A QUICK 1-3IN OF SNOW TONIGHT. .LONG TERM...(SUNDAY THROUGH FRIDAY) ISSUED AT 403 AM EST SAT DEC 14 2013 NAM SHOWS A CLOSED 500 MB LOW NORTH OF LAKE SUPERIOR 12Z SUN WHICH MOVES SOUTHEAST ON SUN. ANOTHER UPPER TROUGH DIGS SOUTHEAST INTO THE AREA FOR MON NIGHT. NAM SHOWS SOME 850-500 MB Q-VECTOR CONVERGENCE 12Z MON MOVING INTO THE AREA WITH SOME DEEPER MOISTURE WHICH REMAINS INTO MON NIGHT. LAKE EFFECT SNOW WILL CONTINUE THIS PERIOD FOR SUNDAY INTO SUNDAY EVENING WITH COLD AIR IN NORTHWEST AND NORTH LAKE EFFECT SNOW BELTS. ON MONDAY...THERE COULD BE SOME LAKE ENHANCEMENT MON AFTERNOON AND EVENING OFF OF LAKE MICHIGAN AND HAVE THIS COVERED WITH LIKELY POPS IN THE EASTERN CWA FOR SOUTHWEST WIND FLOW. HAVE LIKELY POPS MON NIGHT ACROSS THE KEWEENAW FOR WEST FLOW LAKE EFFECT SNOW BELTS. DID NOT MAKE TOO MANY CHANGES TO THE GOING FORECAST FOR TEMPERATURES. IN THE EXTENDED...GFS AND ECMWF SHOW A BROAD 500 MB TROUGH OVER THE CENTRAL AND EASTERN U.S. 12Z TUE. THIS TROUGH PULLS EAST 12Z WED WITH SFC HIGH PRESSURE ALONG THE MISSISSIPPI RIVER VALLEY. SFC LOW PRESSURE MOVES INTO THE CENTRAL PLAINS 12Z THU. GFS AND ECMWF SHOW A 500 MB TROUGH OVER THE NORTHERN PLAINS AND DESERT SW 12Z FRI. COLDER THAN NORMAL TEMPERATURES LOOK TO CONTINUE THIS FORECAST PERIOD EXCEPT FOR A BRIEF RESPITE ON THU INTO FRIDAY BEFORE COLD AIR ARRIVES AGAIN. STILL LOOKS COLD ENOUGH WITH A WARM FRONT TO THE SOUTH AND WARM AIR JUST TO THE SOUTH TO KEEP THE PCPN AS SNOW ON THU...BUT WILL HAVE TO WATCH THIS AS THERE IS A LOW POSSIBILITY OF SOME MIXED PCPN IN THE FAR SOUTH. BASICALLY...LAKE EFFECT SNOW WILL CONTINUE THROUGH WED BEFORE SYSTEM KICKS OUT ON THU. COLD AIR THEN ARRIVES AGAIN LATE ON FRIDAY. && .AVIATION...(FOR THE 12Z TAFS THROUGH 12Z SUNDAY MORNING) ISSUED AT 626 AM EST SAT DEC 14 2013 A SHORTWAVE AND DEVELOPING INVERTED TROUGH MOVING ACROSS UPPER MICHIGAN TODAY WILL LEAD TO INCREASING CHANCES OF LIGHT SNOW SHOWERS AND LOWERING CEILINGS THROUGH THE DAY. EXPECT THE SNOW AND LOWER CEILINGS TO IMPACT KIWD FIRST AND THEN SPREAD TO KCMX/KSAW LATE INTO THE AFTERNOON AND EARLY EVENING. UPSTREAM OBS GENERALLY INDICATE MVFR/VFR VISIBILITIES WITH THE LIGHT SNOW AND WILL CONTINUE TO FOLLOW THAT TREND. A LITTLE UNCERTAIN ON HOW SOON THE CEILINGS AT KIWD WILL GO DOWN DUE TO THE UNFAVORABLE EAST-SOUTHEAST FLOW...SO HAVE HELD THEM UP UNTIL THE BEST SNOW OCCURS IN THE AFTERNOON. FOR KCMX/KSAW THIS MORNING...THE LAKE EFFECT SNOW SHOWERS THAT WERE IMPACTING KSAW WILL CONTINUE NW THROUGH NOON. THINK THE SHOWERS WILL BRUSH OR MISS KCMX TO THE NORTHEAST...SO HAVE TRENDED VISIBILITIES UP THIS MORNING AND KEPT CEILINGS AT MVFR. DID BRING CEILINGS DOWN AT KSAW EARLIER THAN THE OTHER SITES DUE TO FAVORABLE UPSLOPE SOUTHEAST FLOW LATE THIS AFTERNOON. AS A LOW DEVELOPS ALONG THE TROUGH IN NORTHERN LAKE SUPERIOR THIS EVENING AND THEN MOVES SOUTHEAST OVERNIGHT...EXPECT A COLD FRONT TO SWEEP ACROSS UPPER MICHIGAN AND SHIFT WINDS TO THE NORTHWEST. BELIEVE THERE WILL BE A STRONG LINE OF SNOW SHOWERS ALONG THIS FRONT AND THEN TRANSITIONING TO LAKE EFFECT OVERNIGHT AND CONTINUING INTO SUNDAY. MODELS HAVE DECENT AGREEMENT ON TIMING...WITH IT SWEEPING THROUGH KIWD/KCMX BETWEEN 05-07Z SUNDAY AND HAVE FOLLOWED THAT IDEA FOR THOSE SITES. THE UNFAVORABLE WEST-NORTHWEST FLOW FOR KSAW SHOULD LEAD TO A TRANSITION TO VFR CEILINGS/VISIBILITIES. && .MARINE...(FOR THE 4 AM LAKE SUPERIOR FORECAST ISSUANCE) ISSUED AT 503 AM EST SAT DEC 14 2013 HIGH PRESSURE OVER SOUTHERN ONTARIO EARLY THIS MORNING WILL MOVE EAST INTO SOUTHWEST QUEBEC TODAY WHILE A LOW PRESSURE SYSTEM TAKING SHAPE IN THE LOWER MISSISSIPPI VALLEY MOVES INTO THE MID ATLANTIC STATES. WHILE THIS OCCURS...A LOW PRESSURE TROUGH WILL SETUP OVER THE UPPER GREAT LAKES THIS AFTERNOON AND THEN DEVELOP INTO A WEAK LOW TONIGHT BEFORE SHIFTING SOUTHEAST SUNDAY AFTERNOON INTO SUNDAY NIGHT. EXPECT GENERALLY LIGHT WINDS ALONG THIS TROUGH TODAY AND TONIGHT...BUT DO EXPECT THEM TO INCREASE OUT OF THE NORTHWEST ON SUNDAY...WITH GUSTS TO 30KTS EXPECTED SUNDAY AFTERNOON/EVENING. WINDS WILL QUICKLY DIMINISH LATE SUNDAY NIGHT BEFORE INCREASING OUT OF THE SOUTHWEST ON MONDAY (GUSTS TO 30KTS) AHEAD OF A CLIPPER LIKE LOW MOVING SOUTHEAST THROUGH SOUTHERN CANADA AND BRUSHING THE UPPER GREAT LAKES ON MONDAY NIGHT AND TUESDAY. AS THE COLD FRONT SWEEPS THROUGH ON MONDAY NIGHT...EXPECT WINDS TO SHIFT TO THE NORTHWEST AND BE IN THE 20-30KT RANGE. THERE COULD EVEN BE SOME GALE FORCE GUSTS TO 35KTS TUESDAY INTO TUESDAY NIGHT. ANOTHER QUICK HIGH PRESSURE RIDGE WILL MOVE IN ON WEDNESDAY AND DIMINISH WINDS AHEAD OF LOW DEVELOPING IN THE CENTRAL PLAINS AND EXPECTED TO MOVE THROUGH THE GREAT LAKES REGION ON THURSDAY NIGHT. && .MQT WATCHES/WARNINGS/ADVISORIES...
