...GREAT LAKES WATER LEVELS WELL ABOVE NORMAL IN DECEMBER...

EVEN THOUGH WATER LEVELS TYPICALLY FALL SLOWLY IN DECEMBER AND
MONTHLY PRECIPITATION WAS NOT AS SIGNIFICANT AS IN RECENT MONTHS...
THE RUNOFF FROM THE ABOVE NORMAL PRECIPITATION THAT FELL ACROSS THE
UPPER GREAT LAKES AND SURROUNDING AREAS IN RECENT MONTHS AS WELL AS
RELATIVELY CHILLY LAKE WATER TEMPERATURES THAT HAVE LIMITED
EVAPORATION CONTRIBUTED TO A SLOW RISE IN THE LEVELS OF LAKES
MICHIGAN AND HURON IN DECEMBER 2014. AT THE END OF THE MONTH...THE
LEVEL OF THESE LAKES WAS ALMOST 23 INCHES HIGHER THAN IN DECEMBER
2013 AND 9 INCHES ABOVE THE LONG TERM NORMAL. THE LEVEL OF LAKE
SUPERIOR FELL SLOWLY DURING DECEMBER BECAUSE MUCH OF THE
PRECIPITATION IN ITS DRAINAGE BASIN THE LAST TWO MONTHS FELL AS SNOW
AND LIMITED RUNOFF. EVEN SO...THE LAKE SUPERIOR WATER LEVEL ON 12/31
WAS AROUND 9 INCHES HIGHER THAN DURING DECEMBER 2013 AND 7 TO 8
INCHES HIGHER THAN THE MONTHLY NORMAL DUE TO THE LONGER TERM WET
PATTERN AND DIMINISHED EVAPORATION.

DUE TO WARM WEATHER THAT PREVAILED MUCH OF THE MONTH...THERE WAS
LITTLE ICE BUILDUP AWAY FROM SOME OF THE SHELTERED BAYS ON THE
WESTERN GREAT LAKES IN DECEMBER.

                      DECEMBER CLIMATE HIGHLIGHTS

HIGHEST REPORTED TEMPERATURE...49 AT STAMBAUGH IN IRON COUNTY AND BIG
                                BAY IN MARQUETTE COUNTY ON 12/15

LOWEST REPORTED TEMPERATURE...-26 AT WAKEFIELD IN GOGEBIC COUNTY
                               ON 12/31

HIGHEST AVERAGE TEMPERATURE...27.2 DEGREES AT COPPER HARBOR

LOWEST AVERAGE TEMPERATURE...18.1 DEGREES AT HERMAN IN BARAGA COUNTY AND
                              STAMBAUGH IN IRON COUNTY

HIGHEST MONTHLY PRECIPITATION...3.51 INCHES AT ATLANTIC MINE IN
                                 HOUGHTON COUNTY

LOWEST MONTHLY PRECIPITATION...1.60 INCHES AT MARQUETTE CITY

HIGHEST MONTHLY SNOWFALL...46.7 INCHES AT PAINESDALE IN HOUGHTON COUNTY

LOWEST MONTHLY SNOWFALL...5.1 INCHES AT MENOMINEE

GREATEST SNOW DEPTH...39 INCHES AT HERMAN ON 12/29

LOWEST SNOW DEPTH...ZERO AT MENOMINEE ON NUMEROUS DAYS DURING THE
                     SECOND HALF OF DECEMBER AND AT SOME OTHER
                     LOCATIONS NEAR THE GREAT LAKES AT TIMES DURING
                     THE MONTH

ALTHOUGH THE NORTHWEST FLOW ALOFT ON THE WESTERN FLANK OF A DEEP
UPPER TROUGH IN EASTERN NORTH AMERICA BROUGHT A STREAM OF COLD
CANADIAN AIR INTO THE GREAT LAKES DURING THE FIRST WEEK OF DECEMBER
AND THE FINAL COUPLE OF DAYS OF THE MONTH...MUCH OF THE MIDDLE OF
DECEMBER WAS DOMINATED BY A MORE MODERATE FLOW OF MARITIME POLAR
PACIFIC AIR. THE RESULT WAS A MEAN MONTHLY TEMPERATURE THAT RAN 2 TO
4 DEGREES ABOVE NORMAL. THE AVERAGE DECEMBER TEMPERATURE BETWEEN
ABOUT 18 AND 27 DEGREES WAS ONLY 1 TO 5 DEGREES LOWER THAN THE
NOVEMBER MEAN BECAUSE NOVEMBER WAS SO COLD.

THE WARMEST WEATHER OCCURRED AROUND MID-MONTH WHEN A VERY MILD
PACIFIC AIRMASS MOVED INTO THE WESTERN GREAT LAKES UNDER AN UPPER
RIDGE. MEAN DAILY TEMPERATURES RAN AS MUCH AS 15 TO 25 DEGREES ABOVE
NORMAL ON 12/13 THROUGH 12/15...A PERIOD OF DAYS WHEN NUMEROUS DAILY
RECORD HIGH MINIMUM AND MAXIMUM RECORDS WERE BROKEN. AT SOME OF THE
WARMER LOCATIONS OVER THE SOUTH CENTRAL...THE MERCURY DID NOT FALL
BELOW 32 FROM LATE ON 12/12 UNTIL THE EVENING ON 12/16. AT LEAST A
FEW LOCATIONS SAW THE THERMOMETER PEAK IN THE 40S ON 12/12 THROUGH
12/16. MANY PLACES OVER THE SOUTH CENTRAL LOST THEIR SNOW COVER
DURING THIS WARM STRETCH...WHEN SOME RAIN ALSO FELL AS A LOW
PRESSURE SYSTEM MOVED NORTHEAST FROM THE CENTRAL PLAINS INTO THE
UPPER LAKES ON 12/15 AND 12/16.

DURING ARCTIC AIR INVASIONS IN EARLY DECEMBER AND LATE IN THE
MONTH...MEAN DAILY TEMPERATURES FELL TO AS MUCH AS 15 TO 20 DEGREES
BELOW NORMAL ON 12/1...12/2...12/4...AND 12/29 THROUGH 12/31. SUB
ZERO MINIMUM TEMPERATURES OCCURRED AT AT LEAST A FEW SPOTS ON
12/1...12/2...12/4...12/6... 12/11...12/19 AND 12/28 THRU 12/31.

SINCE THE MORE VARIABLE FLOW ALOFT ALLOWED SOME MOISTURE-LADEN LOW
PRESSURE SYSTEMS TO MOVE FARTHER NORTH...MONTHLY PRECIPITATION
TENDED TO RUN ABOVE NORMAL EXCEPT IN A SWATH FROM NEAR MARQUETTE TO
MUNISING AND NEWBERRY. DECEMBER TOTALS WERE HIGHEST OVER THE
NORTHWEST DUE TO THE COMBINATION OF MORE LAKE EFFECT SNOW IN THOSE
AREAS AS WELL AS THE RAIN AND SNOW THAT ACCOMPANIED THE LARGER SCALE
LOW PRESSURE SYSTEMS. AT THE HOUGHTON COUNTY AIRPORT...THE 3.33
INCHES OF WATER EQUIVALENT PRECIPITATON THAT FELL WAS ABOUT 175
PERCENT OF THE DECEMBER NORM FOR THAT SITE. ON THE OTHER HAND...
SINCE THE ABSENCE OF ARCTIC AIR MUCH OF THE MIDDLE OF DECEMBER
RESULTED IN DIMINISHED LAKE EFFECT SNOW ESPECIALLY IN THE SNOW BELTS
EAST OF MARQUETTE...THOSE LOCATIONS WERE DRIER. THE 1.60 INCHES OF
LIQUID EQUIVALENT PRECIPITATION THAT FELL AT MARQUETTE WAS ABOUT 80
PERCENT OF THE DECEMBER AVERAGE. MUNISING REPORTED 2.82 INCHES...
JUST 75 PERCENT OF THEIR MONTHLY NORMAL.

ALTHOUGH PRECIPITATION WAS ABOVE AVERAGE OVER THE WEST...SOME OF
THIS FELL IN THE FORM OF RAIN DURING THE WARMER PERIODS IN MID-
DECEMBER. WITH THE BELOW NORMAL LAKE EFFECT SNOW...DECEMBER SNOW
TOTALS WERE BELOW NORMAL ALMOST EVERYWHERE. EVEN IN THE FAVORED SNOW
BELTS ACROSS WESTERN UPPER MICHIGAN AND EAST OF MARQUETTE...
MONTHLY SNOW TOTALS WERE NO HIGHER THAN ABOUT 35 TO 45 INCHES...
ABOUT 60 TO 75 PERCENT OF THE DECEMBER NORMAL. THE ONE EXCEPTION WAS
AN AREA OVER THE SOUTH CENTRAL NEAR THE WISCONSIN BORDER FROM IRON
RIVER TO IRON MOUNTAIN THAT SAW ALMOST 10 INCHES OF THE WHITE STUFF
ON THE NORTHERN FLANK OF A LOW PRESSURE SYSTEM MOVING THROUGH THE
CENTRAL GREAT LAKES ON 12/27. IRON MOUNTAIN LOGGED 22.1 INCHES OF
SNOW IN DECEMBER...ALMOST 160 PERCENT OF THE MONTHLY NORMAL 13.9
INCHES.
---------------------------------------------------------------------
                  ...2014 ANNUAL WEATHER SUMMARY...

ALTHOUGH 2014 WAS THE WARMEST YEAR ON RECORD IN TERMS OF GLOBAL
AVERAGE ANNUAL TEMPERATURE...THAT WAS NOT THE CASE IN UPPER
MICHIGAN. DUE TO THE NORTHWEST FLOW ALOFT THAT PREVAILED MUCH OF THE
TIME BETWEEN A PERSISTENT RIDGE OVER WESTERN NORTH AMERICA AND A
TROUGH OVER THE EAST HALF OF THE CONTINENT...COLD CANADIAN AIRMASSES
WERE FREQUENT VISITORS TO THE UPPER GREAT LAKES. AS A RESULT...THE
MEAN 2014 TEMPERATURE AT MOST LOCATIONS IN THE U.P. ENDED UP FROM
ABOUT 3.5 TO 4.5 DEGREES BELOW NORMAL.

2014 WAS ALSO A WET ONE...WITH ABOVE NORMAL ANNUAL SNOWFALL AS WELL.
IN FACT...SOME LOCATIONS ENDURED A TOP FIVE WETTEST AND SNOWIEST
YEAR. THE COMBINATION OF THIS ABOVE NORMAL PRECIPITATION AND REDUCED
EVAPORATION TIED TO THE OVERALL CHILL ALLOWED WATER LEVELS OVER
LAKES SUPERIOR...MICHIGAN AND HURON TO RISE WELL ABOVE NORMAL BY THE
END OF THE YEAR.

               ...TOP 5 COLDEST YEAR AT MOST PLACES...

                       DECEMBER WEATHER SUMMARY

MORE TO COME LATER.

                          FEBRUARY FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING AN EQUAL CHANCE
OF AN ABOVE AND BELOW NORMAL MONTHLY MEAN TEMPERATURE AND ABOVE AND
BELOW NORMAL MONTHLY PRECIPITATION OVER ALL OF UPPER MICHIGAN IN
FEBRUARY 2015.

                        FEBRUARY CLIMATOLOGY

ALTHOUGH DAYLIGHT LENGTHENS NOTICEABLY DURING FEBRUARY (580 MINUTES
OF POSSIBLE SUNSHINE ON 2/1 TO 664 MINUTES ON 2/28)...WINTER USUALLY
MAINTAINS ITS ICY GRIP ON UPPER MICHIGAN DURING THE MONTH. IN
FACT...THE LOWEST TEMPERATURE DURING THE YEAR OFTEN OCCURS IN THE
SECOND MONTH. HUMBOLDT IN MARQUETTE COUNTY OBSERVED A FRIGID -49 LOW
ON THE MORNING OF 2/10/1899...THE LOWEST READING EVER RECORDED IN
UPPER MICHIGAN. THE FREQUENT ARRIVAL OF ARCTIC AIRMASSES CAN STILL
CAUSE TEMPERATURES TO PLUNGE AS LOW AS 25 TO 35 BELOW ZERO EVEN
DURING THE LAST WEEK OF THE MONTH. THE COLDEST FEBRUARY IN RECENT
MEMORY WAS IN 2014...WHEN A NEARLY CONTINUOUS FLOW OF CANADIAN AIR
UNDER A PERSISTENT DEEP TROUGH DROPPED THE MEAN MONTHLY TEMPERATURE
TO BETWEEN 9 AND 12 DEGREES BELOW THE FEBRUARY AVERAGE. MANY PLACES
ENDURED A TOP FIVE COLDEST FEBRUARY IN 2014...AND LAKE SUPERIOR AND
NORTHERN LAKE MICHIGAN BECAME ALMOST COMPLETELY ICE COVERED BY THE
END OF THE MONTH. SOME OTHER COLD FEBRUARYS IN THE NOT TOO DISTANT
PAST OCCURRED IN 1994...2003 AND 2007...YEARS WHEN FEBRUARY ENDED UP
AS ONE OF THE TOP TEN COLDEST SECOND MONTHS AT MANY LOCATIONS.

BUT THE CONTINUED CLIMB OF THE SUN IN THE SOUTHERN SKY PROMISES THE
END OF WINTER IS IN SIGHT AND THAT SPRINGTIME IS GETTING CLOSER.
AVERAGE TEMPERATURES RISE STEADILY AFTER THE FIRST WEEK OF THE
MONTH...FROM 12 ON 2/7 TO 17 ON 2/28 AT THE MARQUETTE NWS. DURING
THE LAST HALF OF FEBRUARY...RECORD HIGH TEMPERATURES REACH WELL INTO
THE 50S AND 60S. AT MANY SITES...FEBRUARY 1998...1999...2000 AND
2002 ALL FALL INTO THE TOP 10 WARMEST ON RECORD. IN FEBRUARY 2000...
RECORD WARMTH AFTER 2/21 CAUSED RAPID SNOW MELT...AND ICE JAM
FLOODING WAS OBSERVED ON THE ONTONAGON RIVER. IN FACT...THE
TEMPERATURE AVERAGED 39.3 DEGREES BETWEEN 2/22/2000 AND 2/29/2000 AT
THE MARQUETTE NWS...MARKING THIS 8-DAY PERIOD AS THE WARMEST WEEK IN
THE SECOND MONTH SINCE RECORDS BEGAN IN 1961. BUT AT MOST LOCATIONS
IN UPPER MICHIGAN...FEBRUARY 1998 GOES DOWN IN THE RECORD BOOKS AS
THE WARMEST FEBRUARY EVER. TEMPERATURES AT SOME PLACES ENDED THE
MONTH AS MUCH AS 15 DEGREES ABOVE NORMAL AS A STRONG EL NINO AND
ZONAL PACIFIC FLOW ALOFT PREVENTED THE NORMAL PARADE OF ARCTIC
AIRMASSES FROM INVADING THE UPPER GREAT LAKES.

AVERAGE SNOWFALL OVER UPPER MICHIGAN DURING FEBRUARY IS LESS THAN IN
JANUARY AS THE MEAN POSITION OF THE JET STREAM AND STORM TRACK MOVES
A BIT FARTHER SOUTH. FALLING LAKE SUPERIOR WATER TEMPERATURES AND
THE FORMATION OF ICE ON THE LAKE SOME YEARS ALSO REDUCE THE
INTENSITY OF LAKE EFFECT SNOW. EVEN SO...THERE IS A SHARP DECREASE
IN AVERAGE SNOWFALL FROM AREAS NEAR LAKE SUPERIOR TO INLAND
LOCATIONS ALONG THE WISCONSIN BORDER. WHILE HOUGHTON TYPICALLY
TALLIES ALMOST 33 INCHES OF THE WHITE STUFF...IRON MOUNTAIN WILL LOG
ONLY 10 INCHES DURING A TYPICAL FEBRUARY. ALTHOUGH MONTHLY
TEMPERATURES AVERAGED WELL ABOVE NORMAL...FEBRUARY 2002 WILL LONG BE
REMEMBERED FOR HEAVY PRECIPITATION AND SNOWFALL...ESPECIALLY IN THE
LAKE EFFECT SNOW BELTS. VERY MILD WEATHER INTO FEBRUARY THAT WINTER
MAINTAINED LAKE SUPERIOR TEMPERATURES WELL ABOVE NORMAL...SO THAT
HEAVIER THAN USUAL LAKE EFFECT AND LAKE ENHANCED SNOW ACCOMPANIED A
GREATER THAN AVERAGE NUMBER OF SYNOPTIC STORMS. THE 91.9 INCHES OF
SNOW THAT FELL AT THE MARQUETTE NWS THAT MONTH PUSHES FEBRUARY 2002
TO THE TOP OF THE LIST OF NOT ONLY THE SNOWIEST FEBRUARY...BUT ALSO
THE SNOWIEST CALENDAR MONTH. THE 5.35 INCHES OF LIQUID EQUIVALENT
PRECIPITATION THAT FELL AT THAT LOCATION EASILY ECLIPSED THE
PREVIOUS STANDARD OF 3.62 INCHES OBSERVED IN FEBRUARY 1971. MANY
LOCATIONS FROM IRONWOOD TO NEWBERRY ALSO RECORDED A TOP FIVE
SNOWIEST AND WETTEST FEBRUARY IN 2002. DURING THE COLD FEBRUARY OF
1989...THE HOUGHTON COUNTY AIRPORT RECORDED 89.8 INCHES OF SNOW. NOT
ONLY IS FEBRUARY 1998 THE WARMEST AT MANY LOCATIONS...IT IS ALSO THE
LEAST SNOWY AT MANISTIQUE (1.0 INCH)...IRONWOOD (2.8 INCHES)...
ONTONAGON (5.0 INCHES)...AND THE HOUGHTON COUNTY AIRPORT (5.5
INCHES). MONTHLY SNOWFALLS OF 3.0 INCHES AT NEWBERRY AND 8.8 INCHES
AT MUNISING PLACE FEBRUARY 1998 AMONG THE TOP FIVE LEAST SNOWY.

                        OUTLOOK FOR SPRING

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING A GREATER THAN
CLIMATOLOGICAL CHANCE OF AN ABOVE NORMAL 3-MONTH AVERAGE TEMPERATURE
BUT AN EQUAL CHANCE OF ABOVE AND BELOW NORMAL 3-MONTH PRECIPITATION
OVER ALL OF UPPER MICHIGAN IN MARCH THROUGH MAY 2015.
