...WATER LEVELS REMAIN ABOVE NORMAL IN FEBRUARY...

EVEN THOUGH THE OBSERVED LAKE SUPERIOR WATER LEVEL FELL AGAIN DURING
FEBRUARY, THE WELL ABOVE NORMAL WATER LEVELS AT THE END OF LAST
SUMMER ENSURED THE LAKE LEVEL REMAINED ABOVE AVERAGE THROUGH 2/28.
AT THE END OF FEBRUARY, WATER LEVELS ON LAKE SUPERIOR WERE 6 TO 7
INCHES ABOVE NORMAL BUT 2 TO 3 INCHES LOWER THAN OBSERVED IN
FEBRUARY 2016. THE LEVEL ON LAKES MICHIGAN AND HURON ACTUALLY ROSE A
BIT THROUGH FEBRUARY SO THAT AT THE END OF THE MONTH THE LEVEL WAS 9
TO 10 INCHES ABOVE NORMAL BUT STILL 2 TO 3 INCHES LOWER THAN IN
FEBRUARY 2016.

DUE TO THE OVERALL WINTER WARMTH ACROSS THE UPPER GREAT LAKES, ICE
COVER ON LAKE SUPERIOR AND LAKES MICHIGAN-HURON IN FEBRUARY WAS
RESTRICTED TO THE SHELTERED BAYS ALONG THE SHORES OF THESE GREAT
LAKES.

                     FEBRUARY CLIMATE HIGHLIGHTS

HIGHEST REPORTED TEMPERATURE...64 AT STONINGTON IN DELTA COUNTY
                                ON 2/18

LOWEST REPORTED TEMPERATURE...-22 AT STAMBAUGH IN IRON COUNTY ON 2/4

HIGHEST AVERAGE TEMPERATURE...26.1 DEGREES AT COPPER HARBOR

LOWEST AVERAGE TEMPERATURE...19.4 DEGREES AT CLARKSBURG IN MARQUETTE
                              COUNTY

HIGHEST MONTHLY PRECIPITATION...4.93 INCHES AT GRAND MARAIS
                                 IN ALGER COUNTY

LOWEST MONTHLY PRECIPITATION...0.66 INCH AT ESCANABA

HIGHEST MONTHLY SNOWFALL...73.5 INCHES AT GRAND MARAIS

LOWEST MONTHLY SNOWFALL...4.9 INCHES AT ESCANABA

GREATEST MONTHLY SNOW DEPTH...45 INCHES AT GRAND MARAIS ON 2/16

AS WAS THE CASE IN DECEMBER AND JANUARY, THE FEBRUARY 2017 WEATHER
PATTERN ACROSS THE UPPER GREAT LAKES WAS A VERY CHANGEABLE ONE.
ALTHOUGH THERE WERE BOUTS OF COLD WEATHER MAINLY DURING THE FIRST
HALF OF THE MONTH, A PERIOD OF EXTRAORDINARY WARMTH ASSOCIATED WITH
A STRONG FLOW OF PACIFIC AIR WHICH DOMINATED THE WEEK AFTER MID
MONTH LIFTED THE FEBRUARY AVERAGE TEMPERATURE TO BETWEEN 4 AND 7
DEGREES ABOVE NORMAL, ENOUGH TO QUALIFY THE MONTH AS ONE OF THE TOP
TEN WARMEST FEBRUARYS AT MANY LOCATIONS. MEAN MONTHLY TEMPERATURES
RANGING FROM ABOUT 19 TO 26 DEGREES WERE ABOUT 2 TO 6 DEGREES HIGHER
THAN THE JANUARY NUMBERS.

SINCE THE CHANGEABLE FEBRUARY UPPER FLOW WAS ALSO AN ACTIVE ONE,
MOST PLACES SAW ABOVE NORMAL MONTHLY PRECIPITATION. EVEN THOUGH SOME
OF THIS PRECIPITATION FELL AS RAIN DURING THE WARM PERIOD AFTER MID
MONTH, MONTHLY SNOWFALL IN UPPER MICHIGAN WAS ALSO ABOVE NORMAL AT
MOST PLACES, ESPECIALLY OVER THE KEWEENAW AND NEAR LAKE SUPERIOR
EAST OF MARQUETTE, WHERE PRECIPITATION WAS ENHANCED NEAR LAKE
SUPERIOR. GRAND MARAIS IN ALGER COUNTY LED REPORTING STATIONS ON
PRECIPITATION AND SNOWFALL WITH 4.93 INCHES AND 73.5 INCHES
RESPECTIVELY. OVER 3 INCHES OF WATER EQUIVALENT PRECIPITATION FELL
IN AN AREA FROM MUNISING TO NEWBERRY, AMOUNTS AROUND 175 PERCENT OF
NORMAL. SNOWFALL IN THIS SAME AREA ENDED UP AT LEAST 150 PERCENT OF
THE FEBRUARY AVERAGE AT MOST LOCATIONS. THE 2.84 INCHES OF LIQUID
EQUIVALENT PRECIPITATION MEASURED AT THE HOUGHTON COUNTY AIRPORT IS
A LITTLE OVER DOUBLE THE NORMAL FEBRUARY TOTAL FOR THAT SITE.
PAINESDALE OVER THE HIGHER TERRAIN TO THE SOUTH OF HOUGHTON HAD THE
MOST FEBRUARY SNOWFALL ACROSS THE WEST WITH 62.4 INCHES.

AS IS OFTEN THE CASE, LOCATIONS OVER THE SOUTH CENTRAL SAW THE LEAST
PRECIPITATION AND SNOW IN FEBRUARY. ESCANABA REPORTED ONLY 0.66 INCH
OF WATER EQUIVALENT PRECIPITATION AND 4.9 INCHES OF SNOW IN FEBRUARY,
THE LOWEST U.P. MONTHLY TOTALS IN BOTH CATEGORIES AND JUST 72
PERCENT AND 62 PERCENT OF THE FEBRUARY NORMALS FOR ESCANABA.

AT LEAST ONE SPOT IN THE UPPER PENINSULA SAW THE MERCURY DIP TO -10
OR LOWER ON 2/2, 2/3, 2/4, 2/9, 2/10, 2/16 AND 2/27. STAMBAUGH IN
IRON COUNTY REPORTED THE LOWEST FEBRUARY MINIMUM OF -22 ON 2/4, WHEN
THE WESTERN GREAT LAKES WERE UNDER THE INFLUENCE OF A LARGE CANADIAN
HIGH PRESSURE SYSTEM.

ON THE OTHER HAND, HIGH TEMPERATURES IN THE 50S OCCURRED ON 2/13 AND
EACH DAY FROM 2/17 THROUGH 2/22, THE WEEK WHEN THE WARMEST PACIFIC
AIRMASSES INVADED THE GREAT LAKES AND BROUGHT SOME RECORD WARM
MAXIMUM AND MINIMUM TEMPERATURES. SOME LOCATIONS SAW THE MERCURY
CLIMB OVER 60 ON 2/17 AND 2/18, INCLUDING THE MONTHLY MAXIMUM 64-
DEGREE READING OBSERVED AT STONINGTON IN DELTA COUNTY ON 2/18.
MINIMUM TEMPERATURES HELD ABOVE FREEZING AT AT LEAST A FEW LOCATIONS
ON 2/14 AND EACH MORNING FROM 2/18 UNTIL 2/23, WHEN A DEEPENING
UPPER TROUGH BROUGHT A RETURN OF MORE SEASONABLE CANADIAN AIR TO END
THE MONTH. ON EACH DAY FROM 2/17 THROUGH 2/23, MEAN DAILY
TEMPERATURES RAN AT LEAST 10 TO 25 DEGREES ABOVE NORMAL. ON 2/21,
THE WARMEST DAY OF THIS PERIOD, THE THERMOMETER AVERAGED AROUND 30
DEGREES ABOVE AVERAGE.

                             MARCH 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 MARCH 2017.

                           MARCH CLIMATOLOGY

AS THE SUN CONTINUES ITS MARCH NORTHWARD DURING THE THIRD MONTH OF
THE YEAR...DAYLIGHT AND AVERAGE TEMPERATURES INCREASE STEADILY. THE
POSSIBLE SUNSHINE INCREASES FROM 666 MINUTES ON 3/1 TO 765 MINUTES
ON 3/31. ON 3/1...NORMAL MAXIMUM AND MINIMUM TEMPERATURES AT THE
MARQUETTE NWS ARE 30 AND 8...BUT REBOUND TO 40 AND 20 ON 3/31.
MONTHLY AVERAGE TEMPERATURES THROUGHOUT UPPER MICHIGAN ARE 8 TO 11
DEGREES HIGHER IN MARCH THAN FEBRUARY. REMEMBER TO TURN YOUR CLOCKS
AHEAD ONE HOUR AT 2 AM EST ON SUNDAY 3/12 AS MOST OF THE UNITED
STATES TRANSITIONS FROM STANDARD TIME TO DAYLIGHT SAVINGS TIME.
SPRING ARRIVES IN THE NORTHERN HEMISPHERE THIS YEAR ON 3/20 AT 6:29
AM EDT.

SPRING OFTEN TEASES UPPER MICHIGAN RESIDENTS DURING MARCH WITH
RECORD HIGH TEMPERATURES REACHING WELL INTO THE 60S AND 70S COMMON
BY MONTH`S END. BUT IN MARCH 2012...UNPRECEDENTED WARMTH ARRIVED AT
MID-MONTH AS A SPRAWLING RIDGE OF HIGH PRESSURE DOMINATED THE GREAT
LAKES FOR ALMOST 3 WEEKS. MONTHLY MEAN TEMPERATURES ENDED UP 10 TO
16 DEGREES ABOVE THE LONG TERM AVERAGE...ENOUGH TO PLACE MARCH 2012
AS THE WARMEST THIRD MONTH ON RECORD ALMOST EVERYWHERE EXCEPT FOR
MANISTIQUE. DURING THE WARMEST STRETCH FROM 3/17 TO 3/21...MEAN
DAILY TEMPERATURES AVERAGED AN INCREDIBLE 35 TO 40 DEGREES ABOVE
NORMAL. MANY LOCATIONS REPORTED THE HIGHEST MAXIMUM AND MINIMUM
TEMPERATURE EVER OBSERVED IN MARCH DURING THIS WARM SPELL...
INCLUDING SOME DAYTIME HIGHS IN THE LOW 80S AND OVERNIGHT LOWS IN
THE 50S AND LOW 60S. HARVEY IN MARQUETTE COUNTY LOGGED THE HIGHEST
TEMPERATURE...AN INCREDIBLE 85 ON 3/21. SOME OF THESE DAYS WOULD
HAVE BEEN WARM BY MID-SUMMER STANDARDS. IN RECENT MEMORY...MARCH
2010...2000 AND 1995 WERE ALSO QUITE WARM AND AMONG THE TOP FIVE
WARMEST AT MANY SPOTS. THE EARLY ONSET OF 70- TO 75-DEGREE PLUS
TEMPERATURES BY 3/7 IN MARCH 2000 WAS ALMOST UNPRECEDENTED.

RECORD LOW SNOWFALL AT ALL LOCATIONS DURING MARCH IS AN INCH OR
LESS. MANY LOCATIONS SET THIS MONTHLY RECORD FOR LOW SNOWFALL IN THE
WARM AND DRY MARCH OF 2010. A STRONG EL NINO ALSO RESULTED IN VERY
LOW SNOW TOTALS IN MARCH 1973...WHEN EVEN NORMALLY SNOWY MUNISING
RECORDED A MEAGER 0.5 INCH OF THE WHITE STUFF.

BUT WINTER CAN ALSO SHOW ITS NASTY SIDE DURING MARCH. EVEN ON
3/31...RECORD LOW TEMPERATURES REACH BELOW ZERO AT MANY PLACES...
INCLUDING -17 AT IRONWOOD (3/31/75). DURING THE VERY COLD MARCH
1965...RECORD LOW TEMPERATURES AT THE MARQUETTE NWS DROPPED TO -20
AS LATE AS 3/24/65. ON 3/7/84...THE LOW TEMPERATURE AT IRONWOOD
PLUMMETED TO 34 BELOW ZERO. IN 2003...AN ARCTIC INVASION AT THE
BEGINNING OF THE MONTH DROPPED THE MERCURY AS LOW AS 42 BELOW ZERO
AT EWEN IN ONTONAGON COUNTY ON 3/3. MORE RECENTLY...MARCH 2014
FEATURED LENGTHY PERIODS DOMINATED BY ARCTIC AIRMASSES. THE MEAN
MONTHLY TEMPERATURE THEN RAN 9 TO 13 DEGREES BELOW THE LONG TERM
AVERAGE...EARNING THAT MONTH THE TITLE OF THE COLDEST MARCH ON
RECORD AT IRONWOOD...THE MARQUETTE NWS...MUNISING...MANISTIQUE AND
ONTONAGON AND AS ONE OF THE TOP FIVE COLDEST ELSEWHERE ACROSS UPPER
MICHIGAN.

ALTHOUGH LAKE EFFECT SNOW BECOMES LESS LIKELY DURING MARCH AS LAKE
SUPERIOR TEMPERATURES USUALLY REACH THEIR LOWEST READINGS AND ICE
COVER PEAKS...AVERAGE PRECIPITATION DURING MARCH IS MORE THAN DURING
FEBRUARY BECAUSE THE NORTHWARD MOVING JET STREAM BRINGS MORE
MOISTURE-LADEN LOW PRESSURE SYSTEMS TO THE UPPER GREAT LAKES. THIS
INCREASED STORMINESS RESULTS IN HIGHER AVERAGE SNOWFALL AT INLAND
LOCATIONS THAN IN FEBRUARY. THE AVERAGE MONTHLY SNOW AT IRON
MOUNTAIN DURING FEBRUARY IS 9.1 INCHES...BUT RISES TO 11.1 INCHES IN
MARCH. HEAVY SNOW CAN FALL WHEN LARGE STORM SYSTEMS FUELED BY THIS
ACTIVE MARCH JET STREAM PUSH NORTHEAST FROM THE PLAINS INTO THE
GREAT LAKES. IN FACT...THE SNOWIEST DAY EVER AT THE MARQUETTE NWS
WAS 3/14/97...WHEN A POTENT LOW PRESSURE CENTER MOVED THROUGH
WISCONSIN AND DUMPED 26.2 INCHES OF THE WHITE STUFF...PUSHING THE
SNOW DEPTH TO A RECORD 63 INCHES ON 3/15/97. SINCE THE EARLY WINTER
IN 2001-2002 WAS SO WARM AND LAKE SUPERIOR WATER TEMPERATURES WERE
WELL ABOVE NORMAL LATE IN THE WINTER...HEAVY LAKE EFFECT SNOW FELL
IN MARCH 2002 ONCE VERY COLD AIR PUSHED SOUTH AND CONTRIBUTED TO A
RECORD MARCH SNOWFALL AT THE MARQUETTE NWS (83.1 INCHES)...NEWBERRY
(66.9 INCHES)...AND IRONWOOD (60.8 INCHES). A TOTAL OF 63.5 INCHES
OF SNOW SMOTHERED THE HOUGHTON COUNTY AIRPORT IN MARCH 1976. DURING
THAT SAME MARCH...60.6 INCHES ACCUMULATED AT THE MARQUETTE NWS.
