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 4, 6:40 AM EST, 20 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED AVIATION NATIONAL WEATHER SERVICE MARQUETTE MI 640 AM EST TUE DEC 4 2007 .DISCUSSION... MAIN CONCERN IS LK EFFECT AS COLD PATTERN DOMINATES UPPER LEVEL PATTERN FEATURES TROUGH OVER EASTERN CANADA/GREAT LAKES AND NORTHEAST CONUS WHILE RIDGE IS PRESENT FM SOUTHWEST CONUS INTO WESTERN CANADA. COLD AIR CONTINUES TO SPILL INTO THE GREAT LAKES IN THE NW FLOW ALOFT. H85 TEMPS BLO -15C WITH GOING LAKE TEMPS OF 4-5C ARE MORE THAN SUFFICIENT FOR LK EFFECT SNOW SHOWERS AND WILL REMAIN THAT WAY FOR THE REST OF THE WEEK. BY LATE THIS WEEKEND...UPPER LEVEL PATTERN TRANSITIONS TO A TROUGH OVER THE WESTERN CONUS WITH A MORE ZONAL FLOW INTO THE GREAT LAKES. THIS WILL SIGNAL A WARMING TREND WITH TEMPS RISING TOWARD NORMAL. SFC LOW OVER NORTHEAST CONUS AND STRONG HIGH PRESSURE CENTERED OVER MANITOBA RESULTS IN NORTH WINDS FLOWING ACROSS LK SUPERIOR NEXT 24 HR. EXCEPTION IS OVER WESTERN LK SUPERIOR AND FAR WESTERN UPR MI WHERE WINDS WILL BE DOMINATED BY LAND BREEZES. MOSTLY A SETUP FOR PURE LK EFFECT THROUGH MUCH OF TODAY. 950MB CONVERGENCE IS WEAK UNTIL LATE TODAY WITH APPROACH OF A PAIR OF SHORTWAVES. CURRENT RADAR LOOP SHOWS THAT THE ORGANIZED SNOW SHOWERS FM LAST EVENING HAVE REALLY BECOME MORE SPLOTCHY IN APPEARANCE. SUFFICIENT OVER WATER INSTABILITY WILL KEEP SNOW SHOWERS GOING INTO THE AFTN BUT ACCUMS THROUGH 18Z SHOULD BE MINOR. AFTER 18Z...SHORTWAVE OVER ALBERTA AND SASKATCHEWAN ALONG WITH DEVELOPING SFC LOW SLIDES INTO IOWA BY THIS EVENING AND TO SOUTHERN INDIANA BY 12Z WED. ALSO...ANOTHER SHORTWAVE CURRENTLY OVER NINAVUT IN NORTHERN CANADA SWINGS ACROSS UPR LAKES THIS EVENING. MAJORITY OF LIFT WITH THESE FEATURES WILL NOT IMPACT UPR MI WITH MUCH LARGE SCALE LIFT/SNOW...BUT COULD AID IN INCREASING INVERSION HEIGHTS OF ONGOING LK EFFECT LATE THIS AFTN INTO TONIGHT. 950MB CONVERGENCE DOES INCREASE AS A RESULT OF THE INCREASING FORCING FM THE SHORTWAVES AND THIS SHOULD HELP IN THE ORGANIZATION OF THE LK EFFECT. DURING THIS ENHANCEMENT PERIOD WINDS STAY FM THE NORTH WHICH WILL FAVOR NORTH CENTRAL UPR MI FOR GREATEST SNOW AMOUNTS. LARGE SCALE MODEL AGREEMENT WAS PRETTY GOOD SO HAVE LEANED TOWARD THE LOCAL WRF-ARW FOR SPECIFICS WITH THE LK EFFECT. QPF/SNOW AMOUNTS THIS AFTN AND TONIGHT ARE MAXIMIZED OVER MARQUETTE AND WESTERN ALGER COUNTIES TO START AND LATER IN THE NIGHT OVER FAR WESTERN UPR MI AS DOMINANT BAND OVER WESTERN LK SUPERIOR SINKS SOUTH. EXPECTED QPF AND A 30-40:1 SNOW TO WATER RATIO...AS HAS BEEN THE CASE LAST 24 HR...YIELDS TOTAL SNOW AMOUNTS THIS AFTN AND TONIGHT NEAR ADVISORY. HOWEVER...SINCE LK EFFECT AT THIS TIME IS PRETTY DISORGANIZED AND SHOULD NOT INCREASE MARKEDLY UNTIL LATE TODAY ...WILL HOLD OFF ON ANY HEADLINES FOR NOW AND LET DAYSHIFT SEE HOW THE LK EFFECT RESPONDS TO THE INCOMING FAVORABLE DYNAMICS. SEEMS POSSIBLE THAT DOMINANT BAND AFFECTING FAR WESTERN CWA AFTER 06Z WED COULD PRODUCE A QUICK BURST OF HEAVY SNOW FOR A COUPLE HOURS. WINDS IN WAKE OF THE BAND ARE NOT AS FAVORABLE SO THE HEAVY SNOW WOULD BE SHORT LIVED. HIGH PRESSURE BUILDS IN MORE FOR WED AND WED NIGHT TURNING THE WINDS MORE NORTHWEST. THUS...BY WED AFTN EXPECT HIGHEST POPS TO SHIFT BACK TO TRADITIONAL NW WIND SNOW BELTS OF THE KEWEENAW PENINSULA AND ALONG LAKE SUPERIOR EAST OF MARQUETTE. CONVERGENCE REALLY RAMPS UP WED NIGHT AT THE END OF THE FETCH EAST OF GRAND MARAIS TOWARD WHITEFISH POINT. DEPENDING WHERE THIS DOMINANT BAND SETS UP THERE COULD BE SIGNIFICANT SNOW ACCUMULATIONS IN THE FAR NE CWA WED NIGHT INTO THU. GFS/ECMWF CONTINUE TO SHOW WARM AIR ADVECTION REGIME DEVELOPING LATE THU INTO THU NIGHT. BUMPED UP POPS AWAY FM W FLOW LK EFFECT AREAS AS SOME ACCUMULATING SNOW LOOKS LIKE IT COULD OCCUR...ESPECIALLY IN THE SOUTH. && .AVIATION (FOR THE 12Z TAF ISSUANCE)... THIS FCST PERIOD AT KCMX/KSAW WILL BE DOMINATED BY LAKE EFFECT -SHSN UNDER NRLY WINDS AND THINGS WILL NOT CHANGE MUCH. AS IS TYPICAL FOR LAKE EFFECT...VISIBILITIES WILL FLUCTUATE SIGNIFICANTLY AS BANDS OF -SHSN PASS. WINDS WILL BE LIGHT (GENERALLY AOB 10KT) THRU THE PERIOD...SO BLSN WILL NOT BE AN ISSUE TO FURTHER REDUCE VIS. OVERALL...EXPECT VIS TO FLUCTUATE MOSTLY BTWN MVFR AND IFR THOUGH MVFR WILL BE PREDOMINANT. THERE WILL BE SOME PERIODS OF VFR AND POSSIBLY A FEW VERY BRIEF PERIODS OF LIFR AS WELL. CIGS SHOULD GENERALLY VARY THROUGHOUT THE MVFR RANGE. && .MARINE (FOR THE 4 AM LAKE SUPERIOR FORECAST ISSUANCE)... WINDS WILL CONTINUE TO BE BELOW GALES ON LAKE SUPERIOR THANKS TO THE CURRENT LOW OVER WESTERN QUEBEC HEADING EASTWARD AND A RIDGE OF HIGH PRESSURE BUILDING IN FROM NW ONTARIO AND WESTERN WI AND THIS HIGH WILL NOT MOVE MUCH. HOWEVER...WINDS ARE GOING TO HAVE A HARD TIME DROPPING MUCH BELOW 20 KNOTS THROUGH SATURDAY. IN FACT...THERE COULD BE A PERIOD WHERE THE WINDS GET CLOSE TO GALES WEDNESDAY NIGHT...WHEN HIGH PRESSURE DROPS INTO MN FROM THE NW TERRITORIES AND TIGHTENS THE PRESSURE GRADIENT OVER THE WESTERN GREAT LAKES. && .MQT WATCHES/WARNINGS/ADVISORIES...NONE. && DISCUSSION...JLA AVIATION/MARINE...GJM
