...GREAT LAKES WATER LEVELS RISE SLOWLY AND REMAIN WELL ABOVE
NORMAL IN DECEMBER...

ALTHOUGH GREAT LAKES WATER LEVELS TYPICALLY FALL DURING DECEMBER...
HEAVY MONTHLY PRECIPITATION...MUCH OF WHICH FELL IN THE FORM OF RAIN
DUE TO THE WELL ABOVE NORMAL TEMPERATURES...CAUSED WATER LEVELS ON
THE WESTERN GREAT LAKES TO RISE AN INCH OR TWO DURING THE MONTH. AT
THE END OF DECEMBER...WATER LEVELS ON LAKE SUPERIOR WERE 7 TO 8
INCHES ABOVE NORMAL BUT ABOUT AN INCH LOWER THAN IN DECEMBER 2014.
THE LEVEL ON LAKES MICHIGAN AND HURON WAS ABOUT 10 INCHES ABOVE
AVERAGE ON 12/30 AND 2 TO 3 INCHES HIGHER THAN IN DECEMBER 2014.

GREATEST SNOW DEPTH...18 INCHES AT PAINESDALE

DECEMBER 2015 WILL GO DOWN IN THE RECORD BOOKS AS THE WARMEST TWELFTH
MONTH ON RECORD AT MOST PLACES IN UPPER MICHIGAN DUE TO THE INFLUENCE
OF A RECORD STRONG EL NINO...WHICH CAUSED A PERSISTENT WEST-TO-EAST
FLOW OF MILD PACIFIC AIR TO DOMINATE THE WEATHER PATTERN ACROSS NORTH
AMERICA MOST OF THE TIME DURING THE MONTH. SINCE THIS FLOW PREVENTED
THE FREQUENT INFUSIONS OF CANADIAN AIR TYPICAL FOR THE WINTER...
DECEMBER MEAN TEMPERATURES RANGING FROM 25 TO 34 DEGREES RAN 9 TO 12
DEGREES ABOVE THE MONTHLY NORMAL AND WERE ONLY 5 TO 9 DEGREES LOWER
THAN THE NOVEMBER AVERAGES. THE WARMTH WAS MOST PRONOUNCED WITH LOW
TEMPERATURES DURING THE FIRST HALF OF DECEMBER...WHEN MEAN DAILY
TEMPERATURES ON MOST DAYS WERE 10 DEGREES OR MORE ABOVE NORMAL. THE
WARMTH WAS MOST ANOMALOUS AT NIGHT. THE ONLY COLD AIR OUTBREAKS
DURING DECEMBER OCCURRED ON 12/17 INTO 12/20 AND 12/27 INTO 12/29.
BUT EVEN ON THE COLDEST DAYS DURING THESE PERIODS...MEAN DAILY
TEMPERATURES RAN NO MORE THAN A FEW DEGREES BELOW NORMAL.

THERE WERE NO SUB-ZERO TEMPERATURES REPORTED IN DECEMBER AT ANY SPOT
IN UPPER MICHIGAN. IN FACT...THE MERCURY FELL UNDER 10 ABOVE AT AT
LEAST ONE LOCATION IN UPPER MICHIGAN ONLY ON 12/19...12/20 AND
12/28...DAYS WHEN THOSE INFREQUENT POLAR AIRMASSES HAD INVADED THE
AREA. AT MANY LOCATIONS...DECEMBER 2015 IS NOW THE DECEMBER WITH THE
FEWEST DAYS THAT HAVE A LOW TEMPERATURE UNDER 10 DEGREES. ON THE
OTHER HAND...MANY PLACES HAD MORE DAYS WITH MINIMUM TEMPERATURES AT
OR ABOVE FREEZING IN DECEMBER 2015 THAN DURING ANY PAST DECEMBER.
MOST OF THESE BALMY OVERNIGHTS OCCURRED DURING THE WARM SECOND WEEK
OF THE MONTH...A PERIOD WHEN CLOUD COVER WAS MORE WIDESPREAD AND
HELPED TO MINIMIZE THE NOCTURNAL FALL OF TEMPERATURE. DURING THE
WARMEST NIGHTS ON 12/9...12/10...12/11...12/13 AND 12/14...READINGS
AT SOME OF THE WARMER LOCATIONS NEAR THE GREAT LAKES DID NOT FALL
BELOW 40. THIS ANOMALOUS WARMTH RESULTED IN MANY NEW DAILY RECORD
HIGH MINIMUM TEMPERATURES. THE ONLY DAYS WHEN THE THERMOMETER PEAKED
AT 50 OR HIGHER WERE 12/4...12/5...12/23 AND 12/24. WITH THE WARM
WEATHER INTO 12/24...MANY PLACES OVER SOUTH CENTRAL AND EASTERN
UPPER MICHIGAN HAD A BROWN CHRISTMAS IN 2015.

                         DECEMBER WEATHER SUMMARY

SINCE THE FLOW OF PACIFIC AIR ADVECTED AIRMASSES THAT WERE MOISTER
THAN NORMAL INTO THE UPPER LAKES...DECEMBER PRECIPITATION RAN WELL
ABOVE AVERAGE ACROSS UPPER MICHIGAN. MANY PLACES EXPERIENCED A TOP
TEN WARMEST DECEMBER AND REPORTED MORE THAN 5 INCHES OF WATER
EQUIVALENT PRECIPITATION...OVER 300 PERCENT OF NORMAL AT SOME
LOCATIONS. IN FACT AT IRON MOUNTAIN AND MANISTIQUE...DECEMBER 2015
IS THE WETTEST DECEMBER ON RECORD. MUCH OF THIS PRECIPITATION FELL
DURING A MID MONTH STORM ON 12/14 INTO 12/15...WHEN RAINFALL TOTALS
APPROACHED 3 INCHES OVER THE SOUTHEAST U.P.

ALTHOUGH PRECIPITATION WAS WELL ABOVE NORMAL...MUCH OF THIS FELL IN
THE FORM OF RAIN DUE TO THE OVERALL WARMTH. THERE WAS ALSO A NEAR
ABSENCE DURING THE FIRST HALF OF THE MONTH OF THE LAKE EFFECT SNOWS
THAT ARE COMMON IN DECEMBER DUE TO THE ANOMALOUS WARMTH THAT
PREVAILED DURING THAT PERIOD. THE RESULT WAS WELL BELOW NORMAL
SNOWFALL THAT WAS GENERALLY A TOP TEN LOWEST ACCUMULATION FOR
DECEMBER. SOME PLACES...MAINLY OVER THE SOUTHEAST UPPER PENINSULA...
DID NOT REPORT ANY ACCUMULATING SNOW UNTIL 12/28...WHEN A LOW
PRESSURE MOVING THROUGH THE CENTRAL GREAT LAKES DELIVERED A MODERATE
SNOWFALL TO MAINLY THE SOUTHEAST HALF. AS A RESULT...MOST PLACES
OVER THE SOUTH CENTRAL AND NEAR LAKE SUPERIOR EAST OF MARQUETTE
MEASURED NO MORE THAN 6 INCHES OF SNOW. THESE SNOW TOTALS WERE AS
LITTLE AS 10 PERCENT OF NORMAL AT MUNISING...WHICH REPORTED A RECORD
LOW DECEMBER SNOWFALL OF 5.5 INCHES. ALTHOUGH SNOWFALL OVER THE
HIGHER TERRAIN OF THE NORTHWEST HALF REACHED AS MUCH AS 25 TO 35
INCHES...THESE TOTALS ARE GENERALLY NO MORE THAN ABOUT 50 PERCENT OF
THE MONTHLY NORMAL.

A DEEP LOW PRESSURE SYSTEM MOVING NORTHEAST INTO THE WESTERN GREAT
LAKES BROUGHT A WINTRY MIX OF SNOW...SLEET...FREEZING RAIN AND RAIN
TO UPPER MICHIGAN ON 12/1. AS MUCH AS 2 TO 3 INCHES OF SNOW
ACCUMULATED OVER THE HIGHER TERRAIN OF NORTHWEST UPPER MICHIGAN...
BUT LITTLE IF ANY SNOW FELL OVER THE SOUTHEAST HALF. WATER
EQUIVALENT PRECIPITATION WAS GENERALLY 0.25 TO 0.50 INCH.

AS THE ZONAL FLOW ALOFT TRANSITIONED TO AN UPPER RIDGE OVER THE
UPPER GREAT LAKES ON 12/4 AND 12/5...WARM PACIFIC AIR DOMINATED THE
UPPER GREAT LAKES. MEAN DAILY TEMPERATURES RANGING FROM ABOUT 10
DEGREES ABOVE NORMAL ON 12/1 ROSE TO AS MUCH AS 15 TO 20 DEGREES
ABOVE AVERAGE ON 12/4 AND 12/5...WHEN HIGH TEMPERATURES AT A FEW
SPOTS TOPPED OUT IN THE 50S AT SOME LOCATIONS WITH AT LEAST SOME
PARTIAL SUNSHINE AND AS HIGH AS THE MONTHLY MAXIMUM OF 56 AT BIG BAY
IN MARQUETTE COUNTY ON 12/4. AT SOME PLACES...MORNING LOWS ON 12/5
DID NOT FALL BELOW FREEZING. ALTHOUGH A WEAK COLD FRONT PASSED ON
12/6 AS THE UPPER RIDGE WEAKENED...THE MERCURY FELL OFF ONLY TO
ABOUT 10 DEGREES ABOVE NORMAL ON 12/6 AND TO 5 DEGREES ABOVE AVERAGE
ON 12/7.

A MOIST FLOW OF MILD PACIFIC AIR DOMINATED ON 12/8 THROUGH 12/12...
RESULTING IN PLENTY OF CLOUDS...SOME LOCALLY DENSE FOG ESPECIALLY
DURING THE NIGHT ON 12/7-12/8 AND PATCHY DRIZZLE. A WEAK DISTURBANCE
PASSING ON 12/9 BROUGHT A PERIOD OF SHOWERS WITH UP TO 0.10 TO 0.25
INCH OF RAIN. A STRONGER LOW PRESSURE SYSTEM TRACKING FROM THE
NORTHERN PLAINS INTO NORTHWEST ONTARIO CAUSED MORE RAIN SHOWERS ON
12/10. AS A BIT COLDER AIR FOLLOWED THE ATTENDANT COLD FRONTAL
PASSAGE DURING THE NIGHT ON 12/10-12/11... THE RAIN CHANGED TO WET
SNOW OVER THE NORTHWEST HALF. AS MUCH AS 0.25 TO 0.75 INCH OF WATER
EQUIVALENT PRECIPITATION FELL DURING THIS EVENT...WITH AN INCH OR
TWO OF WET SNOW ACCUMULATING OVER THE KEWEENAW EARLY ON 12/11. MEAN
DAILY TEMPERATURES ON 12/8 THROUGH 12/11 AVERAGED 15 DEGREES ABOVE
NORMAL. OVERNIGHT LOWS HOLDING ABOVE 32 AT MANY PLACES ESTABLISHED
NEW DAILY RECORD HIGH MINIMUMS ON ALL THREE DAYS. IN FACT...SOME
LOCATIONS NEAR THE WARMING INFLUENCE OF THE GREAT LAKES DID NOT SEE
THE THERMOMETER FALL BELOW 40 EARLY ON 12/9...12/10 AND 12/11. EVEN
THOUGH SLIGHTLY COLDER AIR MOVED IN ON 12/12 FOLLOWING THE PASSAGE
OF A WEAK DISTURBANCE THAT DROPPED SOME LIGHT SNOW AND RAIN...MEAN
DAILY TEMPERATURES THAT DAY WERE STILL 10 TO 15 DEGREES ABOVE NORMAL.

A SOUTHWEST FLOW ALOFT ON THE WESTERN FLANK OF A BUILDING UPPER
RIDGE OVER THE SOUTHEAST STATES ALLOWED A MOISTURE-LADEN LOW
PRESSURE SYSTEM TO MOVE NORTHEAST FROM THE SOUTHERN PLAINS ON 12/13
INTO THE UPPER LAKES ON 12/14. LIGHT RAIN WELL IN ADVANCE OF THIS
LOW MOVED INTO THE AREA ON 12/13...WHEN THERE WAS ALSO SOME LOCALLY
DENSE FOG. A STEADIER...HEAVIER RAIN THEN OVERSPREAD THE U.P. ON
12/14. NORTHEAST WINDS GUSTING UP TO 35 TO 45 MPH OVER THE NORTHWEST
DREW ENOUGH COLD AIR INTO WESTERN UPPER MICHIGAN TO ALLOW THE
PRECIPITATION TO AT LEAST MIX WITH SNOW...SLEET AND FREEZING RAIN IN
THAT AREA. ONCE THE LOW LIFTED TO THE NORTHEAST INTO CANADA...THE
PRECIPITATION CHANGED MAINLY TO SNOW DURING THE NIGHT ON 12/14-12/15
AS THE COLDER AIR SURGED INTO THE ENTIRE AREA. BY THE TIME THE
WIDESPREAD PRECIPITATION TAPERED OFF TO FLURRIES...DRIZZLE AND
FREEZING DRIZZLE ON 12/15 IN THE WAKE OF THE DEPARTING LOW IN
SOUTHEAST CANADA...TOTAL LIQUID PRECIPITATION DURING THIS EVENT
RANGED FROM ABOUT AN INCH OVER THE KEWEENAW TO AROUND 3 INCHES OVER
THE SOUTHEAST. GARDEN CORNERS IN DELTA COUNTY LOGGED THE MOST WITH
3.05 INCHES. WET SNOWFALL OVER THE HIGHER TERRAIN OF THE NORTHWEST
HALF ON 12/14 INTO 12/15 WAS BETWEEN 1 AND 5 INCHES. THE THERMOMETER
CONTINUED TO RUN WELL ABOVE NORMAL ON 12/13 INTO 12/15...WITH
READINGS 15 TO 20 DEGREES ABOVE AVERAGE ON 12/13 DIPPING TO AROUND
ONLY 10 DEGREES ABOVE NORMAL ON 12/15. MORNING LOWS ON 12/13 AND
12/14 WERE VERY WARM...WITH MINIMUMS HOLDING ABOVE 32 AT MOST PLACES
AND EVEN OVER 40 AT A FEW LOCATIONS NEAR THE LAKES.

AFTER A BRIEF BREAK...ANOTHER LOW PRESSURE SYSTEM MOVING NORTHEAST
FROM THE PLAINS TOWARD THE UPPER MISSISSIPPI RIVER VALLEY BROUGHT
ANOTHER ROUND OF MIXED PRECIPITATION TO UPPER MICHIGAN ON 12/16.
ALTHOUGH THE STORM BEGAN AS A RAIN/SNOW MIX...THE PRECIPITATION
CHANGED PRIMARILY TO RAIN SINCE THE LOW PRESSURE SYSTEM TRACKED SO
FAR TO THE WEST. MOST PLACES LOGGED 0.25 TO 0.50 INCH OF WATER
EQUIVALENT PRECIPITATION. NO MORE THAN AN INCH OF WET SNOW FELL...
MAINLY OVER THE HIGHER TERRAIN OF THE NORTHWEST. WEST TO NORTHWEST
WINDS GUSTING UP TO 40 TO 45 MPH BEHIND THE LOW DEPARTING INTO
ONTARIO DREW ENOUGH COLDER AIR INTO THE GREAT LAKES TO CAUSE SOME
MODERATE TO HEAVY LAKE EFFECT SNOW IN THE SNOW BELTS FAVORED BY THAT
FLOW BEGINNING ON 12/17. THE INFLUX OF COLD AIR ALSO CAUSED AN UPPER
TROUGH TO DEEPEN OVER THE NORTH CENTRAL STATES INTO 12/19. WITH THE
PERSISTENT FLOW OF COLD AIR...THE MODERATE TO HEAVY LAKE EFFECT
SNOWS CONTINUED AS WELL INTO 12/19 ACROSS THE WEST TO NORTHWEST WIND
SNOW BELTS. THE SNOW SHOWERS WERE HEAVIEST OVER NORTHERN ONTONAGON
COUNTY AND THE KEWEENAW AS WELL AS NEAR LAKE SUPERIOR FROM GRAND
MARAIS IN ALGER COUNTY OVER TOWARD WHITEFISH POINT. SNOWFALL IN
EXCESS OF A FOOT FELL AT MANY PLACES IN HOUGHTON COUNTY. SOME OF THE
MORE IMPRESSIVE TOTALS WERE 23 INCHES NEAR CHASSELL AND 20 INCHES AT
TOIVOLA. GRAND MARAIS LOGGED THE MOST SNOW IN THE EASTERN SNOW BELTS
DURING THIS PERIOD WITH 9 INCHES. GUSTY WEST TO NORTHWEST WINDS ALSO
RESULTED IN CONSIDERABLE BLOWING SNOW INTO 12/18...WHEN THE WINDS
BEGAN TO DIMINISH. WITH THE INFLUX OF COLD AIR...MEAN DAILY
TEMPERATURES THAT RAN ABOUT 15 DEGREES ABOVE NORMAL ON 12/16 FELL
OFF TO ABOUT 10 DEGREES ABOVE AVERAGE ON 12/17 AND THEN TO NEARLY 5
DEGREES BELOW NORMAL ON 12/18 AND 12/19...WHEN AN APPROACHING HIGH
PRESSURE RIDGE CAUSED THE LAKE EFFECT SNOW TO DIMINISH.

A MILDER WEATHER PATTERN RETURNED ON 12/20 THROUGH 12/22 FOLLOWING
THE RETREAT OF THE DEEP UPPER TROUGH INTO CANADA. ALTHOUGH A WEAK
DISTURBANCE PASSING THROUGH THE AREA BROUGHT SOME LIGHT SNOW AND
FREEZING DRIZZLE ON 12/21 INTO 12/22...ANY PRECIPITATION WAS ON THE
LIGHT SIDE. MEAN DAILY TEMPERATURES ROSE TO 5 TO 10 DEGREES ABOVE
AVERAGE ON 12/20 AND 10 TO 15 DEGREES ABOVE NORMAL ON 12/21 AND
12/22.

AS AN UPPER TROUGH DEEPENED ACROSS WESTERN NORTH AMERICA AND A RIDGE
BUILT OVER THE EAST...A STRENGTHENING SOUTHWEST FLOW ALLOWED ANOTHER
MOISTURE-LADEN LOW PRESSURE SYSTEM TO MOVE FROM THE PLAINS TOWARD
THE WESTERN GREAT LAKES ON 12/23. SINCE THIS FLOW ALSO BROUGHT A
RETURN OF UNSEASONABLY WARM WEATHER THAT LIFTED TEMPERATURES AS HIGH
AS A DAILY RECORD 50 ON 12/23 INTO EARLY 12/24...THE BULK OF THE
PRECIPITATION ASSOCIATED WITH THIS LOW FELL AS RAIN. AFTER THE LOW
LIFTED TO THE NORTH AND INTO ONTARIO ON 12/24...WEST WINDS GUSTING
AS HIGH AS 50 TO 60 MPH FOLLOWING THE ACCOMPANYING COLD FRONTAL
PASSAGE BROUGHT A RETURN OF COLDER AIR...LAKE EFFECT SNOW AND SOME
BLOWING SNOW OVER THE WEST AND NORTH CENTRAL EARLY ON CHRISTMAS EVE
MORNING. THIS PRECIPITATION...GUSTY WINDS AND BLOWING SNOW ENDED
WITH THE ARRIVAL OF A WEAK HIGH PRESSURE SYSTEM LATER ON 12/24. THE
GUSTY WINDS ON 12/24 DOWNED NUMEROUS TREES IN THE ESCANABA/GLADSTONE
AREA. PRECIPITATION TOTALS DURING THIS EVENT RANGED FROM AROUND 0.50
INCH OVER THE EAST HALF OF UPPER MICHIGAN TO AS MUCH AS 1.00 TO 1.25
INCHES OVER THE WEST... WHERE 2 TO 6 INCHES OF SNOW FELL ON
CHRISTMAS EVE. IRONWOOD HAD THE MOST SNOW WITH 6.5 INCHES. WITH THE
RETURN OF WARMER WEATHER AND THE RAIN ON 12/23 AND 12/24...MANY
PLACES AWAY FROM THE ACCUMULATING LAKE EFFECT SNOW THAT FELL OVER
THE WEST AND HIGHER TERRAIN OF THE NORTH CENTRAL HAD A BROWN
CHRISTMAS IN 2015. MEAN DAILY TEMPERATURES RAN AS HIGH AS 20 TO 25
DEGREES ABOVE NORMAL ON 12/23...WHEN THE MERCURY NEVER FELL BELOW 32
AND ESTABLISHED A NEW DAILY RECORD HIGH MINIMUM AT MANY PLACES. THE
MEAN DAILY TEMPERATURE FELL TO 10 TO 20 DEGREES ABOVE NORMAL ON
12/24 AND TO 5 TO 10 DEGREES ABOVE AVERAGE ON CHRISTMAS DAY...WHICH
WAS MOSTLY CLOUDY WITH WEAK HIGH PRESSURE PASSING JUST TO THE SOUTH.

A LOW PRESSURE WAVE MOVING ALONG A COLD FRONT DROPPING SLOWLY
THROUGH THE UPPER GREAT LAKES CAUSED PERIODS OF SNOW OVER MAINLY THE
NORTHWEST HALF OF UPPER MICHIGAN ON 12/26. THIS SNOW TRANSITIONED TO
LAKE EFFECT SNOW SHOWERS DURING THE NIGHT ON 12/26-12/27 AS SOMEWHAT
COLDER AIR FOLLOWED THE FRONTAL PASSAGE. THIS GENERALLY LIGHT LAKE
EFFECT SNOW CONTINUED INTO 12/28. SLOWLY VEERING WINDS TO THE
NORTHEAST ON THE SOUTHERN FLANK OF HIGH PRESSURE MOVING ACROSS
ONTARIO LIMITED THE RESIDENCE TIME OF THE BANDS AND OVERALL
ACCUMULATIONS. TOTAL SNOWFALL DURING THE 12/26 INTO 12/28 TIME
VARIED FROM FROM LESS THAN AN INCH OVER THE SOUTHEAST TO 4 TO 8
INCHES OVER THE NORTHWEST HALF...WHERE HOUGHTON-HANCOCK LED
REPORTING STATIONS WITH THE 8 INCH SNOWFALL. WATER EQUIVALENT
PRECIPITATION REACHED UP TO 0.50 TO 0.55 INCH IN THIS AREA OF
HEAVIER SNOW. MEAN DAILY TEMPERATURES RUNNING AROUND 10 DEGREES
ABOVE NORMAL ON 12/26 FELL TO NEAR NORMAL ON 12/28 AS THE COLD
AIRMASS MOVED OVER THE UPPER LAKES.

A DEEPENING LOW PRESSURE THAT TRACKED NORTHEAST FROM THE SOUTH
CENTRAL STATES ACROSS NORTHERN LOWER MICHIGAN EARLY ON 12/29 BROUGHT
A PERIOD OF MODERATE SNOW TO MAINLY THE SOUTHEAST HALF OF UPPER
MICHIGAN LATE ON 12/28 THROUGH THE MORNING ON 12/29. THIS SNOW
DIMINISHED TO SOME LIGHT LAKE EFFECT SNOW SHOWERS DURING THE
AFTERNOON ON 12/29 AS THE LOW CONTINUED NORTHEAST INTO ONTARIO AND
WEAKENED. MOST PLACES OVER THE SOUTHEAST HALF PICKED UP 4 TO 6
INCHES OF THE WHITE STUFF...WITH AS MUCH AS 7 INCHES FALLING AT
GLADSTONE IN DELTA COUNTY. LIQUID EQUIVALENT PRECIPITATION WAS AS
HIGH AS 0.75 INCH IN THIS AREA. LESS THAN AN INCH OF SNOW
ACCUMULATED OVER THE KEWEENAW...WHICH WAS FARTHEST FROM THE LOW
TRACK. AN AREA OF WEAK HIGH PRESSURE BROUGHT QUIETER CONDITIONS WITH
LOTS OF CLOUDS BUT JUST SOME LIGHT LAKE EFFECT SNOW SHOWERS ON 12/30
AND 12/31. MORE MODERATE SNOW SHOWERS DEVELOPED IN THE EVENING ON
NEW YEAR`S EVE ACROSS THE KEWEENAW AS A LOW PRESSURE TROUGH MOVED
INTO THE UPPER LAKES. THE THERMOMETER AVERAGED 5 TO 10 DEGREES ABOVE
NORMAL ON 12/29 THROUGH 12/31.

                         FEBRUARY FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING A GREATER THAN
CLIMATOLOGICAL CHANCE OF AN ABOVE NORMAL MONTHLY MEAN TEMPERATURE
AND BELOW NORMAL MONTHLY PRECIPITATION OVER ALL OF UPPER MICHIGAN IN
FEBRUARY 2016.

                       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.

                        OUTLOOK FOR SPRING

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING A GREATER THAN
CLIMATOLOGICAL CHANCE OF AN ABOVE NORMAL 3-MONTH AVERAGE TEMPERATURE
AND BELOW NORMAL 3-MONTH PRECIPITATION OVER ALL OF UPPER MICHIGAN IN
MARCH THROUGH MAY 2016. THESE FORECAST TEMPERATURE AND PRECIPITATION
ANOMALIES ARE DUE TO A PERSISTENT EL NINO IN THE TROPICAL EASTERN
PACIFIC OCEAN.
