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

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.

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.

WHILE A WEST-TO-EAST FLOW OF MILD PACIFIC AIR DOMINATED IN EARLY
JANUARY AND LIFTED MEAN DAILY TEMPERATURES ON 1/1 AND 1/2 TO 5 TO 10
DEGREES ABOVE NORMAL, THE PASSAGE OF A STRONG UPPER DISTURBANCE AND
COLD FRONT FOLLOWED BY WEST TO NORTHWEST WINDS GUSTING AS HIGH AS 35
TO 40 MPH ON 1/3 INTO 1/4 BROUGHT A RETURN OF COLDER AIR UNDER A
DEEPENING UPPER TROUGH OVER CENTRAL NORTH AMERICA. STEADY WEST WINDS
THAT ADVECTED VERY COLD ARCTIC AIR OVER THE RELATIVELY WARM WATERS
OF LAKE SUPERIOR THEN RESULTED IN AN EXTENDED PERIOD OF LAKE EFFECT
SNOW SHOWERS IN THE FAVORED SNOW BELTS INTO 1/8, WHEN THE ARRIVAL OF
AN ARCTIC HIGH PRESSURE RIDGE DIMINISHED THE SNOW SHOWERS. BUT
BEFORE THE SNOW SHOWERS ENDED, PAINESDALE AND ATLANTIC MINE PICKED
UP ALMOST 33 INCHES OF SNOW FROM 1/3 INTO 1/8. AT IRONWOOD, HIGH
TEMPERATURES ROSE NO HIGHER THAN -1 AND -3 ON 1/4 AND 1/5
RESPECTIVELY WHEN THE CORE OF THE ARCTIC AIRMASS MOVED OVERHEAD. THE
THERMOMETER BOTTOMED OUT AS LOW AS -4 AT IRONWOOD EARLY ON 1/4, -19
AT STAMBAUGH IN IRON COUNTY ON 1/5, -21 AT WAKEFIELD IN GOGEBIC
COUNTY ON 1/6, AND -25 AT STAMBAUGH ON 1/7. AWAY FROM THE MODERATING
INFLUENCE OF LAKE SUPERIOR ACROSS SOUTHERN UPPER MICHIGAN, THE
COMBINATION OF THE STEADY WINDS AND SUB-ZERO LOW TEMPERATURES
RESULTED IN WIND CHILLS AS LOW AS 25 TO 30 BELOW ZERO DURING THE
EARLY MORNING ON EACH DAY FROM 1/4 TO 1/7. THERE WERE NOTHING MORE
THAN SCATTERED SNOW SHOWERS AND FLURRIES IN THESE AREAS. MEAN DAILY
TEMPERATURES AROUND 5 DEGREES ABOVE NORMAL ON 1/3 FELL TO AROUND 15
DEGREES BELOW AVERAGE ON 1/5 THROUGH 1/7. THE MERCURY ON 1/8
RECOVERED TO AROUND 5 DEGREES BELOW NORMAL AS A HIGH PRESSURE
RIDGE MOVED INTO THE AREA, ENDING THE LAKE EFFECT SNOWS.

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 THIS 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. THE THERMOMETER
AVERAGED NEAR NORMAL ON 1/9 BEFORE READINGS ROSE TO AROUND 10
DEGREES ABOVE NORMAL ON 1/10 AS THE LOW PRESSURE SYSTEM DREW WARMER
AND MOISTER AIR INTO THE UPPER LAKES. THE MEAN DAILY TEMPERATURE ON
1/11 FELL OFF TO AROUND 5 DEGREES BELOW NORMAL AS THE GUSTY WINDS
BEHIND THE COLD FRONTAL PASSAGE ADVECTED ARCTIC AIR BACK INTO THE
AREA.

ANOTHER COLD FRONT MOVED THROUGH THE UPPER GREAT LAKES ON 1/12
FOLLOWING THE PASSAGE OF A STRONG DISTURBANCE THROUGH THE LARGE
SCALE UPPER TROUGH CENTERED OVER HUDSON BAY. ALTHOUGH THERE WERE
ONLY SOME LIGHT SNOW SHOWERS ASSOCIATED WITH THE FRONTAL PASSAGE,
WEST WINDS GUSTED OVER 45 MPH ON 1/12 AT MANY PLACES ACROSS THE
KEWEENAW AND AS HIGH AS 55 MPH AT FREDA IN HOUGHTON COUNTY. SNOW
ACCUMULATIONS DURING THIS EVENT WERE NO MORE THAN 1 TO 3 INCHES, BUT
THE GUSTY WINDS CAUSED A GOOD DEAL OF BLOWING SNOW BEFORE THE
ARRIVAL OF TRAILING HIGH PRESSURE DURING THE NIGHT ON 1/12-1/13
CAUSED THE WINDS TO QUICKLY DIMINISH. TEMPERATURES EARLY ON 1/13
FELL SHARPLY UNDER THE CLEARING SKIES AND LIGHTER WINDS AND AS LOW
AS THE MONTHLY MINIMUM OF -30 AT AMASA IN IRON COUNTY. MOST PLACES
AWAY FROM THE LAKE SHORES REPORTED SUB ZERO LOW TEMPERATURES ON
1/13. MEAN DAILY TEMPERATURES AROUND 5 DEGREES BELOW NORMAL ON 1/12
FELL TO 10 TO 15 DEGREES UNDER THE AVERAGE ON 1/13 DUE TO THE
EXTREME MORNING CHILL.

AS THE UPPER TROUGH IN EASTERN NORTH AMERICA WEAKENED TOWARD THE
MIDDLE OF JANUARY, THE WEATHER PATTERN CHANGED SIGNIFICANTLY TO ONE
FEATURING A WEST-TO-EAST FLOW OF PACIFIC AIR. AFTER NEAR NORMAL MEAN
DAILY TEMPERATURES ON 1/14 AND 1/15, A PERIOD OF VERY WARM WEATHER,
AND AT TIMES EXTRAORDINARY, RECORD WARMTH, THEN DOMINATED UPPER
MICHIGAN WEATHER FROM 1/16 TO 1/26 AS DISCUSSED ABOVE. MEAN DAILY
TEMPERATURES DURING THIS STRETCH WERE 15 TO AS MUCH AS 20 TO 25
DEGREES ABOVE NORMAL.

EXCEPT FOR A LIGHT WINTRY MIX OF SNOW, RAIN, AND FREEZING RAIN THAT
FELL DURING THE MORNING ON 1/17 OVER THE SOUTH CENTRAL ON THE
NORTHERN FLANK OF A LOW PRESSURE SYSTEM MOVING THROUGH THE LOWER
GREAT LAKES, THE PERIOD FROM 1/14 THROUGH 1/19 WAS DOMINATED BY HIGH
PRESSURE AND DRY WEATHER. AREAS OF FOG DEVELOPED DURING THE MORNINGS
ON 1/18, 1/19 AND 1/20 OVER THE MELTING SNOW PACK. MENOMINEE HAD THE
MOST RAIN ON 1/17 WITH 0.22 INCH, BUT ANY SNOWFALL WAS UNDER AN
INCH. A PAIR OF UPPER DISTURBANCES MOVING NORTHEAST FROM THE PLAINS
INTO THE UPPER GREAT LAKES THEN BROUGHT MORE WIDESPREAD RAIN SHOWERS
TO THE AREA DURING THE EVENING ON 1/20 AND AGAIN DURING THE NIGHT ON
1/21-1/22. MOST PLACES PICKED UP 0.10 TO 0.25 INCH OF PRECIPITATION
DURING THE 1/20 EVENT. ON 1/21 INTO EARLY 1/22, THE HEAVIEST RAIN
FELL OVER WESTERN UPPER MICHIGAN, WHERE BARAGA REPORTED 1.09 INCHES.
THERE WERE EVEN A FEW LIGHTNING STRIKES WITHIN THE HEAVIER SHOWERS
THAT ACCOMPANIED THIS DISTURBANCE. RAINFALL RANGED FROM NO MORE THAN
0.05 TO 0.10 INCH OVER MOST OF THE EAST HALF TO 0.25 TO 0.50 AT MOST
PLACES ACROSS THE WEST HALF. MORE DENSE FOG PLAGUED UPPER MICHIGAN
ON 1/21 INTO 1/25, ESPECIALLY DURING THE OVERNIGHT HOURS.

AN UPPER RIDGE BEGAN TO BUILD OVER WESTERN NORTH AMERICA AFTER 1/23,
WHICH THEN CAUSED AN UPPER TROUGH TO GRADUALLY DEEPEN OVER THE EAST
HALF OF THE CONTINENT, HERALDING AN EVENTUAL RETURN OF MORE
SEASONABLE WEATHER TO UPPER MICHIGAN AS A SERIES OF UPPER
DISTURBANCES AND COLD FRONTS EMBEDDED IN THE NORTHWEST FLOW ALOFT
DROPPED THROUGH THE GREAT LAKES. THE FIRST WEAK DISTURBANCE MOVING
THROUGH THE SLOWLY DEEPENING UPPER TROUGH DROPPED 0.05 TO 0.15 INCH
OF RAIN THAT WAS MIXED WITH A LITTLE WET SNOW OVER THE EAST HALF OF
UPPER MICHIGAN ON 1/24. A STRONGER LOW PRESSURE SYSTEM MOVED THROUGH
THE LOWER GREAT LAKES ON 1/25 AND INTO SOUTHEAST CANADA ON 1/26. THE
STRENGTHENING NORTH TO NORTHWEST FLOW ON THE NORTHERN FLANK OF THIS
LOW PRESSURE DREW SUFFICIENTLY COLD AIR INTO THE UPPER LAKES TO
CAUSE SOME SNOW ON 1/25 INTO 1/26, THAT WAS MIXED WITH RAIN OVER THE
SOUTHEAST ON 1/25. AS MUCH AS 1 TO 3 INCHES OF SNOW ACCUMULATED
DURING THIS EVENT OVER THE HIGHER TERRAIN NEAR LAKE SUPERIOR.

ANOTHER DISTURBANCE AND COLD FRONT CROSSED THE UPPER LAKES DURING
THE NIGHT ON 1/26-1/27. INCLUDING THE LAKE EFFECT SNOWS THAT FELL IN
ITS WAKE THROUGH 1/27, AROUND 2 TO 4 INCHES OF THE WHITE STUFF FELL
NEAR LAKE SUPERIOR. WEST TO NORTHWEST WINDS GUSTING AS HIGH AS 40
MPH OVER THE KEWEENAW BEHIND THE COLD FRONTAL PASSAGE CAUSED SOME
BLOWING SNOW AS WELL. A MORE SIGNIFICANT LAKE EFFECT SNOW EVENT
OCCURRED ON 1/28 THROUGH 1/29, WHEN 10 INCHES OR MORE OF SNOW FELL
IN THE NORTHWEST SNOW BELTS TO THE EAST OF MARQUETTE, INCLUDING JUST
OVER 14 INCHES AT MUNISING AND 11 INCHES AT GRAND MARAIS. MEAN DAILY
TEMPERATURES AROUND 10 DEGREES ABOVE NORMAL ON 1/27 FELL TO AROUND 5
DEGREES BELOW NORMAL ON 1/29 AS A MORE SEASONABLE CANADIAN AIRMASS
MOVED INTO THE UPPER LAKES.

THE ARRIVAL OF A HIGH PRESSURE RIDGE DURING THE NIGHT ON 1/29-1/30
DIMINISHED LINGERING SNOW SHOWERS. AS SKIES CLEARED AND WINDS FELL
OFF, TEMPERATURES OVER THE INTERIOR FELL BELOW ZERO AT MANY PLACES

LOW PRESSURE TROUGH MOVING THROUGH THE UPPER GREAT LAKES ON 1/31
BROUGHT A RETURN OF SOME MILDER AIR AND LIGHT SNOW. AROUND 1 TO
3 INCHES OF SNOW FELL ON 1/31. MEAN DAILY TEMPERATURES AROUND 5
DEGREES BELOW NORMAL ON 1/30 REBOUNDED TO 5 TO 10 DEGREES ABOVE

                            MARCH FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING EQUAL CHANCES OF
AN ABOVE AND BELOW NORMAL MONTHLY MEAN TEMPERATURE AS WELL AS ABOVE
AND BELOW 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.

                OUTLOOK FOR SPRING INTO EARLY SUMMER

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING A GREATER
THAN CLIMATOLOGICAL CHANCE OF AN ABOVE NORMAL 3-MONTH AVERAGE
TEMPERATURE BUT EQUAL CHANCES OF ABOVE AND BELOW NORMAL 3-MONTH
PRECIPITATION ACROSS ALL OF UPPER MICHIGAN IN APRIL THROUGH JUNE
