...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.

                               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

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 ON 12/30 AND 12/31. 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 FREQUENT LAKE EFFECT SNOWS 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.

A WEST-TO-EAST OF PACIFIC AIR BROUGHT A PERIOD OF ABOVE NORMAL
TEMPERATURES TO UPPER MICHIGAN THE FIRST COUPLE OF DAYS OF
DECEMBER...WITH MEAN DAILY TEMPERATURES AVERAGING AROUND 5 DEGREES
ABOVE NORMAL ON 12/1 THROUGH 12/4. A DISTURBANCE EMBEDDED IN THIS
ZONAL FLOW MOVED THROUGH THE CENTRAL GREAT LAKES DURING THE NIGHT ON
12/3-12/4...BRINGING A PERIOD OF SNOW. AS MUCH AS 2 TO 4 INCHES
ACCUMULATED OVER SOUTH CENTRAL UPPER MICHIGAN.

AS AN UPPER TROUGH DEEPENED OVER THE WEST...A MOISTURE LADEN LOW
PRESSURE SYSTEM DEVELOPING IN THE CENTRAL PLAINS MOVED NORTHEAST
INTO WISCONSIN ON 12/4 AND THEN ACROSS WESTERN UPPER MICHIGAN INTO
ONTARIO ON 12/5. SNOW AHEAD OF THIS LOW DEVELOPED ON 12/4 AND BECAME
MODERATE TO HEAVY AT TIMES OVER MAINLY THE NORTHWEST HALF OF THE
U.P. EAST WINDS GUSTING UP TO 30-35 MPH OVER THE KEWEENAW CAUSED
SOME BLOWING SNOW AS WELL. BUT AS THE LOW DREW WARMER AIR INTO THE
UPPER LAKES...THE SNOW CHANGED TO A WINTRY MIX OF SLEET...FREEZING
RAIN...AND RAIN SOUTHEAST TO NORTHWEST. THIS WINTRY MIX TRANSITIONED
TO JUST SOME SCATTERED RAIN SHOWERS AS DRIER AIR MOVED IN ALOFT
DURING THE EVENING ON 12/4... WHEN PATCHY FOG DEVELOPED. SOME
LOCATIONS REPORTED MORE PERSISTENT FREEZING RAIN ON COLDER SURFACES.
ONCE THE LOW SHIFTED INTO NORTHERN LAKE SUPERIOR AND THEN ONTARIO IN
THE EARLY MORNING ON 12/5...ITS ASSOCIATED COLD FRONT SURGED ACROSS
UPPER MICHIGAN. WEST WINDS GUSTING AS HIGH AS 45 TO 50 MPH ADVECTED
MUCH COLDER AIR INTO THE AREA...CHANGING ANY LINGERING RAIN SHOWERS
TO SCATTERED SNOW SHOWERS. THE STRONGEST WINDS AND MORE WIDESPREAD
SNOW SHOWERS IMPACTED THE KEWEENAW PENINSULA...WHERE THERE WAS QUITE
A BIT OF BLOWING SNOW AGAIN THROUGH THE DAY ON 12/5. DESPITE A
RETURN OF AT LEAST PARTIAL SUNSHINE AWAY FROM THE KEWEENAW...
TEMPERATURES ON 12/5 TENDED TO FALL THROUGH THE DAY...REACHING ABOUT
10 DEGREES OVER THE WEST LATE IN THE DAY. THE GUSTY WINDS MADE THE
AIR FEEL EVEN COLDER. STORM TOTAL SNOW DURING THIS EVENT RANGED FROM
LESS THAN AN INCH NEAR LAKE MICHIGAN TO AS MUCH AS 6 TO 8 INCHES
OVER THE NORTHWEST. A LOCATION NEAR REDRIDGE IN HOUGHTON COUNTY
REPORTED THE MOST WITH 9 INCHES. SOME PLACES REPORTED CLOSE TO 0.25
INCH OF ICE FROM THE FREEZING RAIN. WATER EQUIVALENT PRECIPITATION
WAS 0.50 TO 1.00 INCH AT MOST SITES. BUT STONINGTON IN DELTA
COUNTY...ALLOUEZ IN KEWEENAW COUNTY AND COPPER HARBOR LOGGED 1.75
INCHES...1.54 INCHES AND 1.23 INCHES RESPECTIVELY ON 12/4 INTO 12/5.

THE WEATHER PATTERN THE SECOND WEEK OF DECEMBER FEATURED A DEEP
UPPER TROUGH OVER CENTRAL NORTH AMERICA BETWEEN RIDGES OFF THE WEST
AND SOUTHEAST COASTS. A BITTERLY COLD NORTHWEST FLOW OF CANADIAN AIR
HELD UPPER MICHIGAN IN ITS GRIP ON 12/6 THROUGH 12/16...DROPPING
MEAN DAILY TEMPERATURES 10 TO AS MUCH AS 20 TO 25 DEGREES BELOW
NORMAL. THE THERMOMETER READ -20F OR LOWER AT AT LEAST ONE LOCATION
ON THE MORNINGS OF 12/10 AND 12/16. STAMBAUGH IN IRON COUNTY WAS THE
COLD SPOT ON BOTH DAYS...WITH A MINIMUM READING OF -22 ON 12/10 AND
-26 ON 12/16. AT THE COLDER PLACES...HIGH TEMPERATURES ON SEVERAL OF
THE DAYS IN THIS COLD STRETCH BARELY RECOVERED ABOVE ZERO. THE
PERSISTENT WEST TO NORTHWEST LOW LEVEL FLOW OF ARCTIC AIR OVER THE
RELATIVELY WARM WATERS OF LAKE SUPERIOR ALSO RESULTED IN FREQUENT
LAKE EFFECT SNOW SHOWERS IN THE SNOW BELTS FAVORED BY THE WEST TO
NORTHWEST WINDS...ESPECIALLY OVER THE KEWEENAW PENINSULA. PAINESDALE
IN HOUGHTON COUNTY WAS BURIED UNDER 44.9 INCHES OF SNOW ON 12/6 INTO
12/13...WHEN A WEAK RIDGE OF HIGH PRESSURE SUPPRESSED THE SNOW
SHOWERS. OF THIS TOTAL...15 INCHES FELL FROM LATE ON 12/5 INTO 12/6.
FOR THE SNOW BELTS EAST OF MARQUETTE...GRAND MARAIS IN ALGER COUNTY
HAD THE MOST WITH A TOTAL OF 22.4 INCHES. NO MORE THAN AN INCH OR
TWO OF SNOW FELL AWAY FROM THE FAVORED LAKE EFFECT SNOW BELTS DURING
THIS TIME.

THE SOUTHWEST FLOW AHEAD OF A CLIPPER TYPE LOW PRESSURE SYSTEM
DROPPING FROM CANADA TOWARD THE UPPER GREAT LAKES BROUGHT WIDESPREAD
SNOW TO UPPER MICHIGAN ON 12/14 INTO 12/15. SNOW ACCUMULATIONS WERE
GENERALLY 2 TO 6 INCHES. BUT THE SOUTHWEST FLOW AHEAD OF THIS
DISTURBANCE CAUSED SOME LOCALLY HEAVY LAKE ENHANCED SNOW OFF LAKE
MICHIGAN. WHERE THE HEAVIEST SNOW SHOWERS CAME ASHORE NEAR THE
GARDEN PENINSULA...ALMOST 13 INCHES ACCUMULATED NEAR FAYETTE IN
DELTA COUNTY. ONCE THE CLIPPER LOW PASSED TO THE EAST...A GUSTY
NORTHWEST WIND TO 35 TO 45 MPH NEAR LAKE SUPERIOR CAUSED QUITE A BIT
OF BLOWING AND DRIFTING SNOW AT EXPOSED LOCATIONS. A LINGERING LOW
PRESSURE TROUGH OVER SOUTHERN LAKE SUPERIOR IN THE WAKE OF THE
DEPARTING CLIPPER BROUGHT MORE MODERATE LAKE EFFECT SNOW TO SOME
AREAS NEAR THE BIG LAKE INTO THE NIGHT ON 12/15...WHEN THE ARRIVAL
OF A HIGH PRESSURE SYSTEM CAUSED THE SNOW SHOWERS TO WEAKEN. SNOW
AMOUNTS OF 3 TO 6 INCHES WERE COMMON NEAR LAKE SUPERIOR...BUT AS
MUCH AS 8 INCHES FELL AT HARVEY IN MARQUETTE COUNTY BEFORE THE SNOW
DIMINISHED BY DAYBREAK ON 12/16 WITH THE ARRIVAL OF THE RIDGE. THIS
SAME HIGH PRESSURE RIDGE CAUSED SKIES TO CLEAR OVER THE SOUTH
CENTRAL AND THE BONE CHILLING COLD REPORTED AT DAWN ON 12/16 AT
STAMBAUGH AND MANY OTHER LOCATIONS AWAY FROM THE MODERATING
INFLUENCE OF LAKE SUPERIOR.

AS THE UPPER TROUGH IN CENTRAL NORTH AMERICA RELAXED DURING THE
THIRD AND FOURTH WEEKS OF DECEMBER...THE INTENSE COLD MODERATED A
BIT. MEAN DAILY TEMPERATURES ON 12/17 THROUGH CHRISTMAS DAY ENDED UP
FROM NEAR NORMAL TO 5 DEGREES BELOW AVERAGE. A WEAK CLIPPER LOW
PRESSURE SYSTEM TRACKING THROUGH ONTARIO DROPPED 1 TO 3 INCHES OF
SNOW AT MOST PLACES FROM LATE ON 12/16 INTO EARLY 12/17. ANOTHER 1
TO 3 INCHES OF THE WHITE STUFF FELL DURING THE DAY ON 12/19 AND
NIGHT ON 12/19-12/20 AS A MORE POTENT UPPER DISTURBANCE CROSSED THE
AREA. THE HEAVIEST SNOW FELL OVER THE NORTH CENTRAL...WHERE 4 TO 6
INCHES WAS COMMON AND AS MUCH AS 8.1 INCHES FELL AT NEGAUNEE IN
MARQUETTE COUNTY. ANOTHER DEEPER LOW PRESSURE SYSTEM TRACKING
THROUGH THE LOWER GREAT LAKES AND INTO SOUTHEAST CANADA ON 12/22
INTO 12/23 BROUGHT SOME SNOW TO MAINLY THE SOUTHEAST HALF OF UPPER
MICHIGAN ON 12/22 AND THEN SOME LAKE ENHANCED SNOW INTO MAINLY THE
NORTH WIND SNOW BELTS NEAR SUPERIOR THROUGH 12/23. TOTAL SNOW
THROUGH THIS TIME RANGED FROM 2 TO 4 INCHES AT MOST PLACES TO 6 TO
12 INCHES OVER THE NORTH CENTRAL FROM THE HURON MOUNTAINS INTO
WESTERN ALGER COUNTY. NEGAUNEE TOPPED REPORTING STATIONS WITH 13.5
INCHES ON 12/22 THROUGH 12/23. A WEAK HIGH PRESSURE SYSTEM FOLLOWED
INTO THE UPPER LAKES DURING THE NIGHT ON 12/23-12/24...DIMINISHING
THE LAKE EFFECT SNOW AND ALLOWING FOR PARTIAL CLEARING. SINCE WINDS
WERE LIGHT...TEMPERATURES RESPONDED BY PLUMMETING BELOW ZERO AT SOME
INLAND LOCATIONS AND AS LOW AS -20 AT NEWBERRY AT DAYBREAK ON 12/24.

SNOW AHEAD OF ANOTHER FAST MOVING LOW PRESSURE SYSTEM MOVING THROUGH
ONTARIO SPREAD ACROSS THE U.P. ON CHRISTMAS EVE AND WAS HEAVIEST
OVER THE EAST WITH A SOUTH WIND OFF THE RELATIVELY WARM WATERS OF
LAKE MICHIGAN. OVER 6 INCHES OF SNOW FELL AT SOME PLACES EAST OF A
LINE FROM GRAND MARAIS TO MANISTIQUE...INCLUDING AN EVEN 12.0 INCHES
AT DOLLARVILLE IN LUCE COUNTY. MOST LOCATIONS TO THE WEST OF THIS
LINE MEASURED 1 TO 3 INCHES INTO CHRISTMAS MORNING BEFORE THE SNOW
DIMINISHED AFTER THE LOW PASSED TO THE EAST. BUT THEN SOME LOCALLY
HEAVY LAKE EFFECT SNOW DEVELOPED IN THE WEST TO NORTHWEST WIND SNOW
BELTS OVER THE WEST IN THE AFTERNOON ON 12/25 AS COLDER AIR FOLLOWED
THE PASSING LOW INTO THE UPPER LAKES. THESE SNOW SHOWERS CONTINUED
THROUGH THE DAY ON 12/26...WHEN MEAN DAILY TEMPERATURES FELL TO
AROUND 10 DEGREES BELOW NORMAL. IN THE SNOW BELTS EAST OF
MARQUETTE...THE SNOW SHOWERS WERE MORE SCATTERED. BY THE TIME THE
LAKE EFFECT SNOWS SHIFTED INTO LAKE SUPERIOR DURING THE EVENING ON
12/26 AS THE WIND TURNED TO THE SOUTHWEST ON THE NORTHERN FLANK OF
HIGH PRESSURE MOVING INTO THE LOWER LAKES...MANY LOCATIONS OVER THE
WEST HAD PICKED UP 6 TO 12 INCHES OR MORE OF LAKE EFFECT SNOW. A
SITE NEAR SILVER CITY IN ONTONAGON COUNTY LOGGED ALMOST 17 INCHES.
MELSTRAND IN ALGER COUNTY SAW THE HIGHEST AMOUNT IN THE EASTERN SNOW
BELTS WITH NEARLY 6 INCHES OF THE WHITE STUFF. CLEARING ASSOCIATED
WITH THE PASSING HIGH PRESSURE RIDGE TO THE SOUTH ALLOWED
TEMPERATURES DURING THE NIGHT ON 12/26-12/27 TO FALL SHARPLY BELOW
ZERO AT MANY PLACES AWAY FROM THE LAKE SUPERIOR SHORE AND ALL THE
WAY TO -19 AT A LOCATION JUST SOUTH OF MUNISING.

DESPITE THE COLD START ON 12/27...THE THERMOMETER RECOVERED QUICKLY
DURING THE DAY AS THE COMBINATION OF SOME SUNSHINE AND A WARMER
SOUTHWEST WIND LIFTED AFTERNOON TEMPERATURES ABOVE FREEZING AT MANY
LOCATIONS IN THE AFTERNOON. THE MILD WEATHER LINGERED THROUGH 12/28
DESPITE PLENTY OF CLOUDS AND SOME PATCHY FREEZING DRIZZLE AND
FLURRIES. NEAR NORMAL MEAN DAILY TEMPERATURES ON 12/27 REBOUNDED TO
ABOUT 10 DEGREES ABOVE AVERAGE ON 12/28. BUT THE WARMTH WAS SHORT
LIVED AS ANOTHER ARCTIC COLD FRONT EMBEDDED IN THE DEEPENING UPPER
TROUGH IN CENTRAL NORTH AMERICA PASSED DURING THE NIGHT OF 12/28-
12/29. THE ARRIVAL OF THE TRAILING BITTERLY COLD AIRMASS LED TO MORE
LAKE EFFECT SNOW SHOWERS IN THE WEST TO NORTHWEST WIND SNOW BELTS
THROUGH 12/31. SNOW TOTALS ON 12/29 THROUGH 12/31 EXCEEDED A FOOT
OVER PORTIONS OF THE KEWEENAW PENINSULA. MOHAWK IN KEWEENAW COUNTY
AND CALUMET IN HOUGHTON COUNTY MEASURED 15.0 AND 12.6 INCHES OF SNOW
RESPECTIVELY. TO THE EAST...GRAND MARAIS REPORTED 8.9 INCHES DURING
THESE THREE DAYS. LITTLE IF ANY SNOW FELL OVER THE SOUTH CENTRAL ON
12/29 THROUGH 12/31.

THE YEAR 2013 ENDED ON A VERY COLD NOTE WITH MEAN DAILY TEMPERATURES
ABOUT 5 DEGREES BELOW AVERAGE ON 12/29 FALLING TO AS MUCH AS 20 TO
25 DEGREES BELOW NORMAL ON 12/30 AND 12/31. THE LOWEST TEMPERATURES
REPORTED WERE -26 AT WAKEFIELD IN GOGEBIC COUNTY AND STAMBAUGH ON
12/30 AND -27 AT STAMBAUGH ON 12/31. THE MERCURY FAILED TO RISE
ABOVE ZERO AT SOME PLACES OVER THE WEST ON 12/30 AND 12/31...
INCLUDING A HIGH OF ONLY -6 AT IRONWOOD ON 12/31. WIND CHILLS FELL
TO AS LOW AS 25 TO 35 BELOW ZERO AT MANY SPOTS OVER THE INTERIOR

                    ...2013 CALENDAR YEAR STATS...
       ...GENERALLY COOL AND WET WITH ABOVE NORMAL SNOWFALL...

ABOVE NORMAL PRECIPITATION WAS THE RULE ACROSS UPPER MICHIGAN IN
2013...WITH MANY LOCATIONS REPORTING A TOP 10 WETTEST CALENDAR YEAR.
IN FACT...LAST YEAR IS NOW THE WETTEST CALENDAR YEAR ON RECORD AT
IRONWOOD AND MANISTIQUE. THE 2013 PRECIPITATION TOTAL OF 53.46
INCHES AT IRONWOOD IS ALMOST 20 INCHES ABOVE AND 150 PERCENT OF
NORMAL.

SINCE A GOOD DEAL OF THIS PRECIPITATION FELL DURING THE COLDER
MONTHS...ANNUAL SNOWFALL WAS ALSO ABOVE AVERAGE AT MOST PLACES IN
2013 AND THE HIGHEST ON RECORD AT MUNISING AND NEWBERRY...WHERE THE
OBSERVED TOTAL OF 222.7 INCHES IS ALMOST 170 PERCENT OF NORMAL.

THE OBSERVED ANNUAL AVERAGE TEMPERATURES BETWEEN ABOUT 37 AND 42
DEGREES IS ABOUT 1 TO AS MUCH AS 2.5 DEGREES BELOW NORMAL...ENOUGH
TO QUALIFY 2013 AS ONE OF THE TOP TEN COOLEST ON RECORD AT SOME
LOCATIONS.

                         FEBRUARY 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 FEBRUARY 2014.

                        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 FEBRUARIES IN RECENT
MEMORY WERE IN 2003 AND 1994...WHEN TEMPERATURES ACROSS UPPER
MICHIGAN AVERAGED 6 TO 9 DEGREES BELOW NORMAL. DURING FEBRUARY
1994...THE MEAN TEMPERATURE AT IRONWOOD WAS A BRUTAL 6.5 DEGREES.
BUT THAT WAS WARM COMPARED TO FEBRUARY 1936...WHEN IRONWOOD`S
AVERAGE TEMPERATURE WAS -0.5 DEGREES. FEBRUARY 2003 RANKS AS THE
COLDEST AT MICHIGAN TECH UNIVERSITY (AVERAGE TEMPERATURE 8.7
DEGREES) AND IN THE TOP FIVE COLDEST AT MUNISING...THE MARQUETTE
NWS...AND IRON MOUNTAIN. MORE RECENTLY...INTENSE COLD PREVAILED
THROUGH MUCH OF FEBRUARY 2007...WHEN THE MONTHLY MEAN TEMPERATURE
RAN 4 TO 8 DEGREES BELOW AVERAGE. THAT MONTH WAS ONE OF THE TOP TEN
COLDEST FEBRUARYS AT ONTONAGON...IRONWOOD...MANISTIQUE...MUNISING...
MARQUETTE CITY AND THE MARQUETTE NWS.

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 A BELOW NORMAL 3-MONTH MEAN TEMPERATURE
OVER THE NORTHWEST HALF OF UPPER MICHIGAN BUT EQUAL CHANCES OF
ABOVE AND BELOW NORMAL TEMPERATURES OVER THE REST OF UPPER MICHIGAN
IN MARCH THROUGH MAY 2014. THE CPC FORECAST SHOWS EQUAL CHANCES OF
ABOVE AND BELOW NORMAL 3-MONTH PRECIPITATION OVER ALL OF UPPER
MICHIGAN FOR THIS COMING MARCH THROUGH MAY.
