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

EVEN THOUGH THE OBSERVED LAKE SUPERIOR WATER LEVEL FELL AGAIN DURING
JANUARY, THE WELL ABOVE NORMAL WATER LEVELS AT THE END OF LAST
SUMMER ENSURED THE LAKE LEVEL REMAINED ABOVE AVERAGE THROUGH 1/31.
AT THE END OF JANUARY, WATER LEVELS ON LAKE SUPERIOR WERE 4 TO 5
INCHES ABOVE NORMAL BUT 4 TO 5 INCHES LOWER THAN OBSERVED IN JANUARY
2016. THE LEVEL ON LAKES MICHIGAN AND HURON ACTUALLY REMAINED NEARLY
STEADY THROUGH JANUARY SO THAT AT THE END OF THE MONTH THE LEVEL WAS
7 TO 8 INCHES ABOVE NORMAL BUT STILL 3 TO 4 INCHES LOWER THAN IN
JANUARY 2016.

                      JANUARY CLIMATE HIGHLIGHTS

HIGHEST REPORTED TEMPERATURE...55 AT BIG BAY IN MARQUETTE COUNTY
                                ON 1/18

LOWEST REPORTED TEMPERATURE...-30 AT AMASA IN IRON COUNTY ON 1/13

HIGHEST AVERAGE TEMPERATURE...24.4 DEGREES AT COPPER HARBOR

LOWEST AVERAGE TEMPERATURE...15.3 DEGREES AT STAMBAUGH IN IRON
                              COUNTY

HIGHEST MONTHLY PRECIPITATION...3.69 INCHES AT MUNISING

LOWEST MONTHLY PRECIPITATION...1.33 INCHES AT GARDEN CORNERS
                                IN DELTA COUNTY

HIGHEST MONTHLY SNOWFALL...71.7 INCHES AT PAINESDALE IN HOUGHTON
                            COUNTY

LOWEST MONTHLY SNOWFALL...4.3 INCHES AT MENOMINEE

GREATEST MONTHLY SNOW DEPTH...39 INCHES AT PAINESDALE ON 1/11

WHILE THERE WAS A STRETCH OF COLD WEATHER IN JANUARY FROM 1/3 TO
1/15 THAT FEATURED MEAN DAILY TEMPERATURES AS MUCH AS 15 DEGREES
BELOW AVERAGE, MUCH OF THE REST OF THE MONTH WAS DOMINATED BY A WEST-
TO-EAST FLOW OF PACIFIC AIR. MEAN DAILY TEMPERATURES DURING THE
WARMEST TIME FROM 1/16 UNTIL 1/26 RAN 15 TO AS MUCH AS 20 TO 25
DEGREES ABOVE NORMAL. THIS EXTRAORDINARY WARMTH EASILY OFFSET THE
FIRST HALF CHILL AS WELL AS SOME COLDER WEATHER THAT OCCURRED NEAR
THE END OF JANUARY. AVERAGE MONTHLY TEMPERATURES RANGING FROM ABOUT
15 TO 25 DEGREES ENDED UP 4 TO 6 DEGREES ABOVE NORMAL AND WERE
WITHIN A DEGREE OR TWO OF THE DECEMBER AVERAGES. IN FACT AT SOME
PLACES, JANUARY 2017 IS NOW ONE OF THE TOP TEN WARMEST FIRST MONTHS
ON RECORD.

DURING THE PERIOD OF COLDEST WEATHER ON 1/4 AND 1/5, SOME LOCATIONS
OVER WESTERN UPPER MICHIGAN REPORTED SUB-ZERO MAXIMUM TEMPERATURES.
AT LEAST ONE SPOT IN THE U.P. SAW THE MERCURY FALL TO -10 OR LOWER
EACH DAY FROM 1/4 THROUGH 1/7, 1/13 THROUGH 1/15, AND ON 1/30.
READINGS DIPPED TO -20 OR LOWER ON 1/6, 1/7, 1/13 AND 1/15,
INCLUDING THE MONTHLY MINIMUM OF -30 AT AMASA IN IRON COUNTY ON
1/13. DURING THE WARM PERIOD THE SECOND HALF OF JANUARY, SOME
LOCATIONS SAW HIGH TEMPERATURES REACH 40 OR HIGHER ON 1/16 THROUGH
1/20 AND AGAIN ON 1/23. THE THERMOMETER PEAKED AT OR ABOVE 50 AT A
COUPLE OF LOCATIONS ON 1/18 AND 1/19. BIG BAY IN MARQUETTE COUNTY
REPORTED THE WARMEST JANUARY TEMPERATURE, AN IMPRESSIVE MAXIMUM OF
55 ON 1/18. ALTHOUGH THESE HIGH TEMPERATURES WERE UNUSUALLY MILD,
MANY PLACES SAW OVERNIGHT LOWS HOLD ABOVE THE FREEZING MARK FOR
SEVERAL DAYS IN A ROW FROM 1/21 TO 1/25. AT HOUGHTON, THE MERCURY
FELL NO LOWER THAN 33 ON 1/21 THROUGH 1/24, SETTING A RECORD FOR THE
MOST CONSECUTIVE DAYS IN JANUARY AT FOUR WHEN READINGS DID NOT FALL
TO AT LEAST THE FREEZING MARK. MANY PLACES SAW SOME NEW DAILY RECORD
HIGH MINIMUM TEMPERATURES ESTABLISHED DURING THIS STRETCH OF DAYS,
WHEN AREAS OF DENSE FOG ALSO OCCURRED OVER THE MELTING SNOW PACK.

ALTHOUGH THERE WERE ONLY TWO WIDESPREAD PRECIPITATION EVENTS IN
JANUARY, THE LOW PRESSURE SYSTEM THAT IMPACTED THE AREA ON 1/10
THROUGH 1/11 DROPPED ENOUGH SNOW THAT MONTHLY PRECIPITATION ENDED UP
NEAR TO ABOVE NORMAL AT MOST LOCATIONS. MUNISING LED REPORTING
STATIONS WITH 3.69 INCHES OF WATER EQUIVALENT PRECIPITATION BECAUSE
THAT SITE ALSO SAW A RELATIVELY HIGH AMOUNT OF LAKE EFFECT SNOW. BUT
SINCE THE EXTENDED WARMTH PREVENTED ANY LAKE EFFECT SNOW FROM 1/16
THROUGH 1/26 AND THE LOW PRESSURE THAT IMPACTED THE AREA ON 1/21
INTO 1/22 DROPPED MAINLY RAIN, JANUARY SNOWFALL WAS NEAR TO BELOW
AVERAGE AT MOST SPOTS. ALTHOUGH PAINESDALE IN HOUGHTON COUNTY
REPORTED THE HEAVIEST JANUARY SNOWFALL WITH 71.7 INCHES, MANY PLACES
OVER THE NORTHWEST HALF OF UPPER MICHIGAN SAW THE LEAST SNOW
RELATIVE TO NORMAL. THE 23.3 INCHES THAT FELL AT IRONWOOD IS ONLY A
LITTLE MORE THAN HALF THE JANUARY NORMAL FOR THAT SITE. OF THE 71.7
INCHES THAT ACCUMULATED AT PAINESDALE, 59.1 INCHES FELL FROM 1/3
INTO 1/14, WHEN THAT SITE WAS IMPACTED BY THE LARGER SCALE LOW
PRESSURE SYSTEM ON 1/10 INTO 1/11 AND THE NEARLY CONTINUOUS LAKE
EFFECT SNOWS THAT PREVAILED DURING THIS PERIOD DOMINATED BY THE FLOW
OF ARCTIC AIR OVER THE RELATIVELY WARM WATERS OF LAKE SUPERIOR.

THE LOW PRESSURE SYSTEM THAT BROUGHT THE HEAVY SNOW TO THE AREA ON
1/10 BEGAN TO TAKE SHAPE IN THE CENTRAL PLAINS ON 1/9. LIGHT SNOW
AHEAD OF THE LOW MOVING NORTHEAST TOWARD THE UPPER LAKES ARRIVED
DURING THE NIGHT ON 1/9-1/10. AS THE LOW GOT CLOSER ON 1/10,
MODERATE TO HEAVY SNOW FELL ACROSS THE UPPER PENINSULA. SINCE THE
LOW MOVED OVER EASTERN UPPER MICHIGAN, LOCATIONS NEAR LAKE MICHIGAN
SAW THE SNOW MIX WITH OR CHANGE TO RAIN FOR A TIME. AS THE LOW MOVED
INTO ONTARIO DURING THE NIGHT ON 1/10-1/11, THE PRECIPITATION
DIMINISHED TO SOME SNOW SHOWERS AT THE SAME TIME WEST TO NORTHWEST
WINDS IN THE WAKE OF THE PASSING LOW GUSTED IN EXCESS OF 50 MPH AT
MANY PLACES. THE STANNARD ROCK LIGHTHOUSE ON EAST CENTRAL LAKE
SUPERIOR REPORTED A WIND GUST OF 76 MPH. THE APPROACH OF ANOTHER
STRONG DISTURBANCE AND COLD FRONT EARLY ON 1/11 CAUSED MORE MODERATE
TO HEAVY SNOW, WHICH DIMINISHED LATER IN THE DAY AFTER THIS
DISTURBANCE SHIFTED TO THE EAST. SNOW TOTALS FROM THE NIGHT ON 1/9-
1/10 THROUGH 1/11 REACHED A FOOT OR MORE AT SOME PLACES. PAINESDALE
AND MUNISING REPORTED THE HIGHEST TOTALS WITH 14 INCHES. IRON
MOUNTAIN, NEGAUNEE IN MARQUETTE COUNTY AND HOUGHTON WERE CLOSE
BEHIND WITH ABOUT 13 INCHES OF THE WHITE STUFF.

ANOTHER LOW PRESSURE CENTER OVER THE CENTRAL PLAINS ON 1/21 TRACKED
TO THE NORTHEAST AND OVER UPPER MICHIGAN ON 1/22. SINCE THIS LOW
IMPACTED THE AREA WHEN THE ANOMALOUSLY WARM PACIFIC AIRMASS
DOMINATED, THE ACCOMPANYING PRECIPITATION FELL AS ALMOST ALL RAIN.
THE HEAVIEST RAIN FELL OVER THE NORTHWEST HALF, WHERE MANY SPOTS
MEASURED 0.50 TO 1.00 INCH, INCLUDING 1.09 INCHES AT BARAGA. THERE
WERE EVEN A FEW LIGHTNING STRIKES WITHIN THE HEAVIER SHOWERS THAT
ACCOMPANIED THIS LOW PRESSURE SYSTEM.

COLDER WEATHER GRADUALLY RETURNED LATE IN JANUARY AFTER 1/26 AS AN
UPPER TROUGH DEEPENED OVER EASTERN NORTH AMERICA, RESULTING IN MORE
FREQUENT LAKE EFFECT SNOWS AGAIN IN THE FAVORED SNOW BELTS NEAR LAKE
SUPERIOR. THE MOST SIGNIFICANT SNOW SHOWERS IMPACTED ALGER AND
SCHOOLCRAFT COUNTIES ON 1/29 INTO 1/30, WHEN JUST OVER 14 INCHES OF
SNOW FELL AT MUNISING.

                           FEBRUARY FORECAST

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

                          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. IN RECENT YEARS...BOTH FEBRUARY
2014 AND 2015 FEATURED SOME RECORD OR NEARLY RECORD LOW MEAN MONTHLY
TEMPERATURES. 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 IN 2014 AND TO
12 TO 15 DEGREES BELOW THE MONTHLY MEAN IN 2015. MANY PLACES ENDURED
A COLDEST OR AT LEAST TOP FIVE COLDEST FEBRUARY IN BOTH THESE
YEARS...AND LAKE SUPERIOR AND NORTHERN LAKE MICHIGAN BECAME ALMOST
COMPLETELY ICE COVERED BY THE END OF BOTH THOSE MONTHS. 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.
