...GREAT LAKES WATER LEVELS FALL SLOWLY IN DECEMBER...

WATER LEVELS ON LAKES SUPERIOR AND MICHIGAN/HURON FELL AN INCH OR
TWO IN DECEMBER...A NORMAL RATE FOR THE END OF THE YEAR. DESPITE
THIS SLOW DECLINE...THE LEVEL ON LAKES MICHIGAN/HURON WAS ABOUT 13
INCHES HIGHER AT THE END OF DECEMBER THAN AT THE END OF DECEMBER IN
2012. FOR LAKE SUPERIOR...THE LEVEL ENDED ABOUT 11 INCHES HIGHER
THAN AT THE END OF 2012. THESE HIGHER LEVELS WERE COURTESY OF A
COMBINATION OF COOLER WEATHER IN 2013 THAT RESTRICTED EVAPORATION
AND OVERALL ABOVE NORMAL ANNUAL PRECIPITATION IN THE DRAINAGE BASINS
FOR THESE LAKES. EVEN WITH THIS IMPROVEMENT...LAKES MICHIGAN/HURON
WERE STILL 15 INCHES LOWER THAN THE LONG TERM AVERAGE. LAKE SUPERIOR
REMAINED 2 TO 3 INCHES LOWER THAN NORMAL.

DUE TO THE UNSEASONABLE DECEMBER CHILL...MOST OF THE BAY OF GREEN
BAY WAS ICE COVERED BY THE END OF DECEMBER. THERE WAS SOME ICE
BUILDUP IN THE SHELTERED BAYS AND INLETS ALONG THE LAKE SUPERIOR
SHORE AS WELL.

HIGHEST REPORTED TEMPERATURE...46 AT MENOMINEE ON 12/4 AND 12/5

LOWEST REPORTED TEMPERATURE...-27 AT STAMBAUGH IN IRON COUNTY
                               ON 12/31

HIGHEST AVERAGE TEMPERATURE...17.6 DEGREES AT COPPER HARBOR

LOWEST AVERAGE TEMPERATURE...6.8 DEGREES AT STAMBAUGH IN IRON COUNTY

HIGHEST MONTHLY PRECIPITATION...4.45 INCHES AT ATLANTIC MINE IN
                                 HOUGHTON COUNTY

LOWEST MONTHLY PRECIPITATION...1.15 INCHES AT CLARKSBURG-CHAMPION
                                IN MARQUETTE COUNTY

HIGHEST MONTHLY SNOWFALL...102.7 INCHES AT PAINESDALE IN HOUGHTON
                            COUNTY

GREATEST SNOW DEPTH...36 INCHES AT ATLANTIC MINE ON 12/16

LOWEST MONTHLY SNOWFALL...9 INCHES AT WITCH LAKE IN MARQUETTE COUNTY

ALTHOUGH A WEST-TO-EAST FLOW OF MARITIME POLAR PACIFIC AIR RESULTED
IN ABOVE NORMAL TEMPERATURES THE FIRST COUPLE OF DAYS OF DECEMBER
2013...A DEEP UPPER TROUGH THAT DOMINATED CENTRAL AND EASTERN NORTH
AMERICA AFTER 12/5 DELIVERED A NEARLY CONTINUOUS FLOW OF ARCTIC AIR
INTO THE UPPER GREAT LAKES THE REST OF THE MONTH. THE RESULT WAS A
TOP TEN COLDEST DECEMBER ALMOST EVERYWHERE...AND EVEN THE THIRD
COLDEST TWELFTH MONTH ON RECORD AT NEWBERRY AND ONTONAGON. MEAN
MONTHLY TEMPERATURES THAT RANGED FROM ABOUT 7 TO 17 DEGREES WERE 6
TO 10 DEGREES BELOW THE LONG-TERM DECEMBER AVERAGE AND 16 TO 21
DEGREES LOWER THAN THE NOVEMBER READINGS.

THE COLDEST WEATHER RELATIVE TO NORMAL IMPACTED THE UPPER GREAT
LAKES DURING THE SECOND WEEK OF DECEMBER. MEAN DAILY TEMPERATURES
FROM 12/6 THROUGH 12/16 AVERAGED 10 TO 20 DEGREES BELOW NORMAL. A
BITTERLY COLD AIRMASS ALSO INVADED THE GREAT LAKES AT THE END OF
DECEMBER...WHEN MEAN DAILY TEMPERATURES ON 12/30 AND 12/31 FELL TO
AROUND 20 DEGREES BELOW NORMAL. THE MERCURY FELL UNDER 20 BELOW ZERO
AT AT LEAST ONE REPORTING SITE ON 12/8...12/10...12/16...12/24...
12/30 AND 12/31. WIND CHILLS WERE AS LOW AS 25 TO 35 BELOW ZERO
DURING THE COLDEST OVERNIGHTS AND MORNINGS. THE ONLY 40-DEGREE
TEMPERATURES REPORTED IN DECEMBER OCCURRED ON 12/2 AND 12/4 INTO
EARLY 12/5...WHEN A SHARP COLD FRONT PLOWED THROUGH THE UPPER LAKES
AND OPENED THE DOOR FOR THE ARCTIC INVASION.

SINCE ONLY ONE MOISTURE-LADEN LOW PRESSURE SYSTEM INFLUENCED UPPER
MICHIGAN WEATHER IN DECEMBER 2013...MONTHLY PRECIPITATION TENDED TO
BE NEAR TO BELOW NORMAL. THE EXCEPTION WAS IN AREAS OVER MAINLY
NORTHWEST UPPER MICHIGAN THAT SAW ALMOST CONTINUOUS LAKE EFFECT SNOW
FROM 12/5 THROUGH 12/31. MONTHLY WATER EQUIVALENT PRECIPITATION IN
THIS AREA APPROACHED OR EXCEEDED 4 INCHES AT MANY LOCATIONS...UP TO
200 PERCENT OF NORMAL AT HOUGHTON. DECEMBER SNOWFALL WAS OVER 100
INCHES AT A FEW PLACES ACROSS CENTRAL HOUGHTON COUNTY IN THE
KEWEENAW PENINSULA. PAINESDALE AND ATLANTIC MINE REPORTED THE
HEAVIEST SNOW WITH 102.7 AND 102.5 INCHES RESPECTIVELY. THE MONTHLY
SNOWFALL IN EXCESS OF 75 INCHES AT MOST PLACES FROM ONTONAGON NORTH
THROUGH THE KEWEENAW RAN 125 TO 175 PERCENT OF THE DECEMBER NORMAL.
AS IS OFTEN THE CASE IN THE COLD SEASON...LOCATIONS OVER SOUTH
CENTRAL UPPER MICHIGAN WERE DRIEST. LESS THAN 2 INCHES OF LIQUID
EQUIVALENT PRECIPITATION FELL AT MANY PLACES IN THIS AREA...AS LOW
AS 75 PERCENT OF NORMAL. BUT SINCE MOST OF THE DECEMBER
PRECIPITATION THAT DID FALL WAS A FLUFFY SNOW...MONTHLY SNOW TOTALS
OVER THE SOUTH CENTRAL WERE NOT FAR FROM THE DECEMBER AVERAGE.

                         JANUARY FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING A GREATER THAN
CLIMATOLOGICAL CHANCE OF A BELOW NORMAL MONTHLY MEAN TEMPERATURE BUT
AN EQUAL CHANCE OF ABOVE AND BELOW NORMAL MONTHLY PRECIPITATION OVER
ALL OF UPPER MICHIGAN IN JANUARY 2014.

                       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.

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 (AVERAGE TEMPERATURE 2.8)...IRON MOUNTAIN (3.0)...
THE HOUGHTON COUNTY AIRPORT (4.9)...MANISTIQUE (5.8)...ONTONAGON
(5.8)...AND MUNISING (7.8). NEWBERRY RECORDED ITS SECOND COLDEST
JANUARY IN 1994 (5.3)...AND IRONWOOD ITS FOURTH COLDEST (-0.3).
WATER PIPES FROZE IN A NUMBER OF HOMES THROUGHOUT UPPER MICHIGAN
THAT COLD MONTH. A BRUTAL ARCTIC OUTBREAK IN MID-JANUARY 2005 DROVE
TEMPERATURES AS LOW AS -31 AT CHAMPION IN MARQUETTE COUNTY. AT
IRONWOOD...THE MERCURY REMAINED BELOW ZERO FROM LATE IN THE
AFTERNOON ON 1/13 UNTIL JUST AFTER DAWN ON 1/18 IN 2005...INCLUDING
A HIGH OF 6 BELOW ZERO ON 1/15. BOTH IRONWOOD AND NEWBERRY...WHERE
RECORDS GO BACK TO THE EARLY 1900S...SAW THEIR COLDEST JANUARY IN
1912...WHEN AVERAGE TEMPERATURES WERE A FRIGID -5.3 AND 2.7
RESPECTIVELY. MORE RECENTLY...JANUARY 2009 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 2009 WAS 3 TO 7 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.

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; AND 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
INCHES). 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 27.7 INCHES (1968).
