...WATER LEVELS FALL BUT REMAIN ABOVE NORMAL IN DECEMBER...

EVEN THOUGH THE OBSERVED GREAT LAKES WATER LEVELS FELL DURING
DECEMBER DUE TO THE DRIER WEATHER OBSERVED THE LAST THREE MONTHS, THE
WELL ABOVE NORMAL WATER LEVELS AT THE END OF SUMMER ENSURED THE
LAKES REMAINED ABOVE AVERAGE THROUGH 12/31. AT THE END OF DECEMBER,
WATER LEVELS ON LAKE SUPERIOR WERE 3 TO 4 INCHES ABOVE NORMAL BUT 3
TO 4 INCHES LOWER THAN OBSERVED IN DECEMBER 2015. THE LEVEL ON LAKES
MICHIGAN AND HURON REMAINED 5 TO 6 INCHES ABOVE NORMAL AT THE END OF
THE MONTH BUT WERE ABOUT 3 INCHES LOWER THAN IN DECEMBER 2015.

                           JANUARY FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING EQUAL CHANCES OF
AN ABOVE AND BELOW NORMAL MONTHLY MEAN TEMPERATURE AND MONTHLY
PRECIPITATION ACROSS ALL OF UPPER MICHIGAN IN JANUARY 2017.

                          JANUARY CLIMATOLOGY

ALTHOUGH DAYLIGHT BEGINS TO INCREASE THROUGH JANUARY (519 MINUTES OF
POSSIBLE SUNSHINE ON 1/1 TO 576 MINUTES ON 1/31)...TEMPERATURES
CONTINUE THEIR DOWNWARD SLIDE DURING THE MONTH AS ARCTIC AIRMASSES
MAKE FREQUENT VISITS TO UPPER MICHIGAN. IN FACT...JANUARY IS THE
COLDEST MONTH AT ALL REPORTING STATIONS...WITH AVERAGE TEMPERATURES
5 TO 6 DEGREES LOWER THAN IN DECEMBER.

AT MANY PLACES...INCLUDING IRONWOOD...IRON MOUNTAIN...NEWBERRY...
MUNISING...HOUGHTON AND MARQUETTE CITY...THE COLDEST JANUARY ON
RECORD...AND FOR THAT MATTER THE COLDEST MONTH...OCCURRED IN JANUARY
1912. DURING THIS FRIGID TIME...MONTHLY AVERAGE TEMPERATURES WERE 15
OR MORE DEGREES BELOW NORMAL AND UNDER ZERO AT SOME OF THESE PLACES.
IRONWOOD WAS COLDEST WITH A MONTHLY MEAN TEMPERATURE OF -5.3
DEGREES. THE MERCURY HELD BELOW ZERO AT THAT LOCATION FROM 1/1 TO
1/13 IN 1912. MORNING LOWS WERE UNDER -30 AT IRONWOOD ON FIVE OF
THESE DAYS AND AS LOW AS -37 ON 1/7. THE COLDEST FIRST MONTH IN
RECENT MEMORY WAS JANUARY 1994...WHEN TEMPERATURES ACROSS ALL OF
UPPER MICHIGAN AVERAGED ABOUT 10 DEGREES BELOW NORMAL AND THE
MERCURY NEVER ROSE ABOVE THE FREEZING MARK. JANUARY 1994 GOES DOWN
IN THE RECORD BOOKS AS THE COLDEST EVER AT THE MARQUETTE
NWS...MANISTIQUE AND ONTONAGON. WATER PIPES FROZE IN A NUMBER OF
HOMES THROUGHOUT UPPER MICHIGAN THAT COLD MONTH. MORE
RECENTLY...JANUARY 2014 WAS A TOP TEN COLDEST FIRST MONTH AT MANY
LOCATIONS WITH A PERSISTENT UPPER TROUGH LOCKED OVER THE GREAT LAKES
THROUGH THE MONTH. THE MEAN MONTHLY TEMPERATURE IN JANUARY 2014 WAS
6 TO 10 DEGREES BELOW NORMAL.

ON THE OTHER SIDE OF THE COIN...JANUARY 2006 IS THE WARMEST FIRST
MONTH ON RECORD AT MOST PLACES ACROSS UPPER MICHIGAN. MONTHLY MEAN
TEMPERATURES AVERAGED AN INCREDIBLE 10 TO 15 DEGREES ABOVE THE
LONG-TERM NORMAL. A STRONG WEST-TO-EAST FLOW ALOFT KEPT ARCTIC AIR
BOTTLED UP WELL NORTH IN CANADA...AND THE DAILY TEMPERATURE ENDED UP
ABOVE THE MEAN ALL 31 DAYS OF THE MONTH AT MOST SITES. THERE WAS
ALMOST A COMPLETE ABSENCE OF SUB-ZERO TEMPERATURES IN JANUARY 2006.
FOR THE FIRST TIME SINCE RECORDS BEGAN IN 1901...THE MERCURY DID NOT
FALL BELOW ZERO IN JANUARY AT IRONWOOD IN 2006. AT IRON MOUNTAIN AND
THE MARQUETTE NWS...2006 JOINS 2002 AS THE ONLY YEAR WHEN THE
THERMOMETER NEVER DIPPED BELOW ZERO IN JANUARY. AT MANY PLACES WEST
OF MUNISING AND ESCANABA...1/27/2006 WAS THE WARMEST OR ONE OF THE
TOP FIVE WARMEST JANUARY DAYS ON RECORD. MAXIMUM TEMPERATURES PEAKED
AT OR ABOVE 50 AT MANY LOCATIONS...INCLUDING THE HOUGHTON COUNTY
AIRPORT. THE PREVIOUS HIGHEST JANUARY TEMPERATURE ON RECORD THERE
HAD BEEN 43. AVERAGE JANUARY TEMPERATURES IN 2002...2001...AND 1990
WERE AMONG THE TOP FIVE HIGHEST ON RECORD AT MANY LOCATIONS.
READINGS DURING THOSE MONTHS AVERAGED 5 TO 10 DEGREES OR MORE ABOVE
NORMAL. EVEN MORE RECENTLY...JANUARY 2012 WAS QUITE WARM. MONTHLY
MEAN TEMPERATURES AVERAGED 4 TO 7 DEGREES ABOVE NORMAL...ENOUGH TO
QUALIFY THAT JANUARY AS ONE OF THE TOP TEN WARMEST FIRST MONTHS ON
RECORD AT MOST PLACES.

JANUARY IS THE SNOWIEST MONTH OF THE YEAR AT MOST LOCATIONS. THE
PASSAGE OF ARCTIC AIR OVER THE TYPICALLY UNFROZEN LAKE SUPERIOR
RESULTS IN CONSIDERABLE LAKE EFFECT SNOW. AS THE COLD AIR PASSES
OVER THE RELATIVELY WARM WATERS OF THE LAKE...THE AIRMASS BECOMES
INCREASINGLY UNSTABLE. THE RESULT IS A GREATER FREQUENCY OF LOW
CLOUD AND SNOW SHOWERS...WHICH ARE TYPICALLY HEAVIER AND MORE
WIDESPREAD OVER HIGHER TERRAIN JUST DOWNWIND OF LAKE SUPERIOR. THE
LOCATION OF MAXIMUM SNOWFALL IS VERY DEPENDENT ON THE LOW LEVEL WIND
DIRECTION BECAUSE THE LONGEST WIND FETCH ACROSS THE WATER RESULTS IN
GREATEST DESTABILIZATION. A WEST WIND FAVORS THE KEWEENAW PENINSULA;
A NORTHWEST WIND USUALLY RESULTS IN HEAVIER SNOW AROUND ONTONAGON
AND IN ALGER AND LUCE COUNTIES...WHILE A NORTH TO NORTHEAST WIND
CAUSES THE HEAVIEST SNOW AROUND IRONWOOD AND IN THE NORTH CENTRAL
HIGHLANDS OF BARAGA AND MARQUETTE COUNTIES. ALTHOUGH LARGE SCALE
STORM SYSTEMS THAT TYPICALLY MOVE NORTHEAST FROM THE PLAINS STATES
INTO THE GREAT LAKES CAN ALSO BRING HEAVY SNOW TO INLAND
LOCATIONS...AVERAGE JANUARY PRECIPITATION IS QUITE A BIT LESS AWAY
FROM LAKE SUPERIOR. FOR INSTANCE...THE HOUGHTON COUNTY AIRPORT PICKS
UP 62.8 INCHES OF SNOW AND 3.71 INCHES OF LIQUID EQUIVALENT
PRECIPITATION DURING A TYPICAL JANUARY. IRON MOUNTAIN RECEIVES ONLY
15.0 INCHES OF SNOW AND 1.25 INCHES OF LIQUID EQUIVALENT
PRECIPITATION ON AVERAGE. WHILE RECORD SNOWS AT INLAND LOCATIONS ARE
TYPICALLY AROUND 50 INCHES... LOCATIONS THAT RECEIVE BOTH LAKE
EFFECT AND SYNOPTIC SNOW CAN PICK UP 100 INCHES OF THE WHITE STUFF.
DURING THE COLD JANUARY OF 2004... A LOCATION JUST SOUTHWEST OF
ONTONAGON WAS BURIED UNDER 121 INCHES OF THE WHITE STUFF. TWO HEART
IN LUCE COUNTY LOGGED 115 INCHES...AND BOTH PAINESDALE IN HOUGHTON
COUNTY AND PHOENIX IN KEWEENAW COUNTY REPORTED 112 INCHES. SNOWFALL
IN JANUARY 1997 WAS ALSO HEAVY...106.3 INCHES FELL AT THE HOUGHTON
COUNTY AIRPORT...100.7 INCHES AT IRONWOOD...91.7 INCHES AT THE
MARQUETTE NWS...AND 88.7 INCHES AT MUNISING.

DURING DRY AND/OR WARM YEARS...MONTHLY SNOWFALL MAY NOT EXCEED 12
INCHES AT MANY LOCATIONS. IRON MOUNTAIN PICKED UP ONLY 2.3 INCHES OF
SNOW IN JANUARY 1961...EVEN THOUGH THE MONTHLY TEMPERATURE WAS NEAR
NORMAL. AN ACTIVE STORM TRACK THAT YEAR TOO FAR TO THE SOUTH LEFT
MUCH OF UPPER MICHIGAN AWAY FROM LAKE SUPERIOR HIGH AND DRY (TOTAL
LIQUID EQUIVALENT PRECIPITATION AT IRON MOUNTAIN WAS ONLY 0.12
INCH). DURING A RELATIVELY DRY AND MILD JANUARY 1973 WHEN THERE WERE
FEW ARCTIC INVASIONS...THE MARQUETTE NWS RECORDED ONLY 12.0 INCHES
OF SNOW. THE RECORD LOW JANUARY SNOWFALL AT THE HOUGHTON COUNTY
AIRPORT IS 13.5 INCHES...MEASURED IN 1944.

                OUTLOOK FOR LATE WINTER INTO SPRING

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING EQUAL CHANCES OF
AN ABOVE AND BELOW NORMAL 3-MONTH AVERAGE TEMPERATURE BUT A GREATER
THAN CLIMATOLOGICAL CHANCE OF ABOVE NORMAL 3-MONTH PRECIPITATION
ACROSS ALL OF UPPER MICHIGAN IN FEBRUARY THROUGH APRIL 2017.
