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

ALTHOUGH GREAT LAKES WATER LEVELS FELL SLOWLY IN JANUARY 2015 AS IS
NORMAL...THESE LEVELS REMAINED WELL ABOVE THE LONG-TERM AVERAGE. AT
THE END OF JANUARY...THE LEVEL OF LAKES MICHIGAN AND HURON WAS 8 TO
9 INCHES HIGHER THAN NORMAL AND ALMOST 22 INCHES HIGHER THAN ON 1/31
IN 2014. AS FOR LAKE SUPERIOR...THE 1/31 LEVEL OF THAT BODY OF WATER
WAS OVER 7 INCHES ABOVE NORMAL AND MORE THAN 8 INCHES HIGHER THAN
OBSERVED ON 1/31 IN 2014.

DUE TO THE INTENSE CHILL THAT PREVAILED DURING THE FIRST HALF OF
JANUARY...THERE WAS CONSIDERABLE ICE DEVELOPMENT IN THE NEARSHORE
WATERS OF THE GREAT LAKES IN JANUARY. THE NORTHERN BAY OF GREEN BAY
BECAME ALMOST COMPLETELY ICE COVERED.

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 JANUARY.

                       JANUARY CLIMATE HIGHLIGHTS

HIGHEST REPORTED TEMPERATURE...41 AT BIG BAY IN MARQUETTE COUNTY
                                ON 1/23 AND NORWAY IN DICKINSON
                                COUNTY ON 1/24

LOWEST REPORTED TEMPERATURE...-31 AT STAMBAUGH IN IRON COUNTY ON 1/13

HIGHEST AVERAGE TEMPERATURE...17.3 DEGREES NEAR ESCANABA

LOWEST AVERAGE TEMPERATURE...8.3 DEGREES AT STAMBAUGH

HIGHEST MONTHLY PRECIPITATION...3.48 INCHES NEAR GRAND MARAIS
                                 IN ALGER COUNTY

LOWEST MONTHLY PRECIPITATION...0.45 INCH AT MENOMINEE

HIGHEST MONTHLY SNOWFALL...60.6 INCHES NEAR GRAND MARAIS

LOWEST MONTHLY SNOWFALL...7.1 INCHES AT MENOMINEE

GREATEST SNOW DEPTH...40 INCHES AT HERMAN BARAGA COUNTY ON 1/4
                       AND 1/10

LOWEST SNOW DEPTH...ZERO AT MENOMINEE ON 1/2 AND 1/26

THE WEATHER PATTERN THE FIRST HALF OF JANUARY 2015 WAS DOMINATED BY
A DEEP TROUGH OVER CENTRAL AND EASTERN NORTH AMERICA DOWNSTREAM OF A
STRONG RIDGE ALONG THE WEST COAST. THE NORTHWEST FLOW BETWEEN THESE
TWO FEATURES DELIVERED A STEADY STREAM OF ARCTIC AIR INTO THE GREAT
LAKES...SO THE MEAN TEMPERATURE THE FIRST TWO WEEKS OF JANUARY
AVERAGED 10 TO 15 DEGREES BELOW NORMAL. BUT THE UPPER FLOW AFTER
1/14 BECAME LESS AMPLIFIED...LIMITING THE INFLUX OF ARCTIC AIR AND
ALLOWING SOME MORE MODERATE MARITIME POLAR PACIFIC AIRMASSES TO
INFLUENCE UPPER MICHIGAN`S WEATHER AT TIMES. ALTHOUGH THE AVERAGE
TEMPERATURE FROM 1/15 THROUGH 1/31 RAN CLOSE TO 10 DEGREES ABOVE
NORMAL...THE CHILL THE FIRST TWO WEEKS WAS SO MUCH MORE ANOMALOUS
THAT JANUARY 2015 ENDED UP COLDER THAN NORMAL OVER THE ENTIRE U.P.
MEAN MONTHLY TEMPERATURES RANGING FROM NEAR 8 DEGREES AT THE COLD
SPOTS OVER THE INTERIOR WEST HALF AND AROUND 17 AT THE WARM SPOTS
NEAR THE GREAT LAKES WERE 8 TO 12 DEGREES LOWER THAN THE DECEMBER
AVERAGES AND RANGED FROM ABOUT 0.5 DEGREE BELOW THE JANUARY NORMAL
OVER THE FAR WEST AT IRONWOOD TO AS MUCH AS 3 TO 5 DEGREES BELOW
AVERAGE OVER THE EAST FROM MUNISING TO NEWBERRY AND MANISTIQUE. THE
REASON THE EAST WAS COLDER RELATIVE TO NORMAL THAN THE WEST IS
BECAUSE THAT AREA WAS CLOSER TO THE CORE OF THE COLDEST AIR THAT
LINGERED OVER EASTERN CANADA EVEN AFTER THE UPPER PATTERN HAD
TRANSITIONED TO A MORE MODERATE ONE THE SECOND HALF OF THE MONTH.

WITH A PERSISTENT WEST TO NORTHWEST FLOW ALOFT...NO MOISTURE-LADEN
LOW PRESSURE SYSTEMS FROM THE PLAINS IMPACTED UPPER MICHIGAN IN
JANUARY. EVEN THOUGH SOME ALBERTA CLIPPER LOW PRESSURE SYSTEMS
EMBEDDED IN THIS FLOW PASSED THROUGH THE UPPER GREAT LAKES AND
DROPPED SOME SNOW...THESE DISTURBANCES WERE MOISTURE DEPRIVED...SO
ACCOMPANYING PRECIPITATION TENDED TO BE ON THE LIGHT SIDE. THE
RESULT WAS BELOW NORMAL MONTHLY PRECIPITATION AND SNOWFALL ALMOST
EVERYWHERE. AS IS TYPICAL IN MID-WINTER...THE LEAST PRECIPITATION
FELL OVER THE SOUTH CENTRAL WHILE THE MOST OCCURRED IN THE NORTHWEST
WIND-FAVORED SNOW BELTS NEAR LAKE SUPERIOR. MENOMINEE REPORTED ONLY
0.45 INCH OF WATER EQUIVALENT PRECIPITATION...AND THE 0.63 INCH THAT
FELL AT IRON MOUNTAIN WAS ABOUT ONLY 50 PERCENT OF THE TYPICAL
JANUARY TOTAL. BECAUSE LAKE EFFECT SNOWS WERE COMMON MAINLY IN THE
NORTHWEST WIND SNOWBELTS DOWNWIND OF LAKE SUPERIOR...ESPECIALLY
DURING THE FIRST HALF OF THE MONTH WHEN ARCTIC AIRMASSES WERE
FREQUENT VISITORS...PRECIPITATION TOTALS IN THE SNOW BELTS EAST OF
MARQUETTE WERE 2 INCHES OR MORE...INCLUDING THE MONTHLY MAXIMUM OF
3.48 INCHES AT GRAND MARAIS IN ALGER COUNTY. MUNISING LOGGED 2.86
INCHES...A LITTLE MORE THAN 87 PERCENT OF NORMAL. EVEN IN THE
FAVORED NORTHWEST WIND SNOWBELTS...JANUARY SNOW TOTALS UP TO ABOUT
60 INCHES AT PAINESDALE IN HOUGHTON COUNTY AND AT GRAND MARAIS WERE
NO MORE THAN ABOUT NORMAL DUE TO THE ABSENCE OF MOIST...LARGER-SCALE
LOW PRESSURE SYSTEMS. THE 42.1 INCHES THAT FELL AT MUNISING IS JUST
ABOUT AVERAGE...BUT HOUGHTON`S MONTHLY TOTAL OF 51.6 INCHES IS ONLY
ABOUT 75 PERCENT OF NORMAL. LOCATIONS OVER THE SOUTH CENTRAL SAW
LESS THAN 10 INCHES OF SNOW IN JANUARY...NO MORE THAN ABOUT 2/3 OF
THE MONTHLY MEAN.

SUB-ZERO MINIMUM TEMPERATURES WERE COMMON DURING THE FIRST TWO WEEKS
OF JANUARY. DURING THE PEAK OF THE COLD FROM 1/5 THROUGH 1/9...THE
MERCURY FAILED TO RECOVER TO THE ZERO MARK AT A NUMBER OF THE COLDER
LOCATIONS DURING THE AFTERNOON. READINGS AT A NUMBER OF INTERIOR
LOCATIONS FELL INTO THE TEENS BELOW ZERO ON 1/2...1/5 THROUGH 1/7...
1/10 THROUGH 1/13 AND ON 1/26. MINIMUMS OF -20 OR LOWER OCCURRED ON
1/5...1/6...1/10...1/12 AND 1/13...INCLUDING THE MONTHLY LOW OF -31
AT STAMBAUGH IN IRON COUNTY ON 1/13. THE WARMEST PERIOD IN JANUARY
WAS FROM 1/22 THROUGH 1/24. HIGH TEMPERATURES IN THE 30S WERE COMMON
ON THESE 3 DAYS...AND A FEW PLACES EVEN REPORTED A HIGH OF 40 OR
BETTER...INCLUDING THE JANUARY MAXIMUM OF 41 AT BIG BAY IN MARQUETTE
COUNTY ON 1/23 AND AT NORWAY IN DICKINSON COUNTY ON 1/24. THE
THERMOMETER EVEN READ NO LOWER THAN ABOUT 32 AT A FEW OF THE WARMER
LOCATIONS ON THE MORNINGS OF 1/23 AND 1/24.

                          FEBRUARY FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING A GREATER THAN
CLIMATOLOGICAL CHANCE OF A BELOW NORMAL MONTHLY AVERAGE TEMPERATURE
OVER THE EAST HALF OF UPPER MICHIGAN BUT EQUAL CHANCES OF AN ABOVE
AND BELOW NORMAL MONTHLY MEAN TEMPERATURE OVER THE WEST HALF IN
FEBRUARY 2015. THE CPC IS FORECASTING AN EQUAL CHANCE OF ABOVE AND
BELOW NORMAL MONTHLY PRECIPITATION OVER ALL OF UPPER MICHIGAN IN
FEBRUARY.

                         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.
