...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. THERE
WERE MORE 60-DEGREE HIGHS ON 2/21. 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. THE WARMEST OVERNIGHT
LOW WAS 43 AT A SPOT NEAR IRONWOOD IN THE MORNING ON 2/20. ON EACH
DAY FROM 2/17 THROUGH 2/23, MEAN DAILY TEMPERATURES RAN AT LEAST 10
TO 25 DEGREES ABOVE NORMAL, AND NEAR 30 DEGREES ABOVE AVERAGE ON
2/18. ON 2/21, THE WARMEST DAY OF THIS PERIOD, THE THERMOMETER
AVERAGED AROUND 30 DEGREES ABOVE AVERAGE.

THERE WERE TWO SIGNIFICANT PRECIPITATION EVENTS IN FEBRUARY THAT
CONTRIBUTED TO THE NEAR TO ABOVE NORMAL MONTHLY PRECIPITATION AND
SNOWFALL AT MOST PLACES ACROSS UPPER MICHIGAN. THE FIRST OF THESE
OCCURRED ON 2/7 AS A DEEP LOW PRESSURE CENTER MOVED FROM NEAR
CHICAGO THROUGH NORTHERN LOWER MICHIGAN. THE HEAVIEST SNOW FELL
ACROSS THE NORTHERN TIER, WHERE SEVERAL PLACES REPORTED 10 INCHES OR
MORE BEFORE THE PRECIPITATION DIMINISHED TO SOME LAKE EFFECT SNOW
SHOWERS DURING THE NIGHT ON 2/7-2/8. SOME OF THE MORE IMPRESSIVE
TOTALS INCLUDE 14.2 INCHES AT PAINESDALE IN HOUGHTON COUNTY AND 11
INCHES AT CHATHAM IN ALGER COUNTY AS WELL AS IRONWOOD. OVER THE
SOUTH, THE PRESENCE OF DRIER AIR AND WARMER TEMPERATURES THAT CAUSED
SOME MIXED PRECIPITATION RESULTED IN MUCH LESS SNOWFALL THAT WAS
UNDER AN INCH IN AN AREA FROM IRON MOUNTAIN TO ESCANABA AND
MANISTIQUE.

ANOTHER DEEP LOW PRESSURE SYSTEM TRACKING NORTHEAST OUT OF AN
UPPER TROUGH IN THE PLAINS BROUGHT A ROUND OF MODERATE TO HEAVY
PRECIPITATION TO UPPER MICHIGAN ON 2/24 INTO 2/25. WHILE MOST OF
THIS FELL IN THE FORM OF SNOW, THERE WAS A WINTRY MIX WITH SOME
SLEET AND LIGHT FREEZING RAIN OVER THE EAST HALF. BY THE TIME THE
PRECIPITATION DIMINISHED DURING THE AFTERNOON ON 2/25, 10 INCHES OR
MORE OF SNOW HAD ACCUMULATED OVER THE HIGHER TERRAIN OF THE
NORTHWEST HALF. PAINESDALE REPORTED THE MOST SNOW WITH 13.8 INCHES.
HERMAN IN BARAGA COUNTY, BERGLAND DAM IN ONTONAGON COUNTY, AND
ATLANTIC MINE IN HOUGHTON COUNTY ALSO HAD A FOOT OR MORE OF SNOW
WITH 13.0, 12.5, AND 12.0 INCHES RESPECTIVELY. LIQUID EQUIVALENT
PRECIPITATION WAS UP TO 0.50 TO 0.75 INCH AT THESE HIGHER TERRAIN
LOCATIONS. MANISTIQUE REPORTED BOTH THE LEAST SNOW AND WATER
EQUIVALENT PRECIPITATION WITH 1.1 INCHES AND 0.27 INCH.

                       FEBRUARY WEATHER SUMMARY

A STRONG COLD FRONT ASSOCIATED WITH A DISTURBANCE TRACKING THROUGH A
DEEP UPPER TROUGH OVER CENTRAL AND EASTERN NORTH AMERICA PASSED
UPPER MICHIGAN ON THE MORNING OF 2/1 AND WAS ACCOMPANIED BY A BURST
OF SNOW SHOWERS THAT DROPPED A FEW INCHES OF SNOW AT PLACES NEAR
LAKE SUPERIOR. NORTH WINDS GUSTING AS HIGH AS 30 TO 35 MPH FOLLOWING
THE FRONTAL PASSAGE CAUSED SOME BLOWING AND DRIFTING SNOW. THE
STRONG WINDS SHIFTED TO THE WEST-NORTHWEST AND GUSTED AS HIGH AS 35
TO 45 MPH ON 2/2 THROUGH 2/3 AHEAD OF ARCTIC HIGH PRESSURE BUILDING
THROUGH THE NORTHERN PLAINS TOWARD THE UPPER MISSISSIPPI RIVER
VALLEY, DRIVING COLDER AIR INTO THE UPPER LAKES. THE RESULT WAS SOME
HEAVY SNOW SHOWERS AND CONSIDERABLE BLOWING SNOW IN THE FAVORED SNOW
BELTS NEAR LAKE SUPERIOR. MOST PLACES DOWNWIND OF LAKE SUPERIOR
ACROSS NORTHWEST UPPER MICHIGAN AND EAST OF MUNISING PICKED UP 3 TO
6 INCHES OF NEW SNOW DURING THIS TIME, BUT AS MUCH AS 18 INCHES
BURIED GRAND MARAIS IN ALGER COUNTY. OVER THE SOUTH CENTRAL, SKIES
WERE CLEAR TO PARTLY CLOUDY WITH NOTHING MORE THAN SOME FLURRIES.
MEAN DAILY TEMPERATURES WITHIN A FEW DEGREES OF NORMAL ON 2/1 FELL
OFF TO 5 TO 10 DEGREES BELOW AVERAGE ON 2/2 AND 2/3 WITHIN THE
INCOMING ARCTIC AIRMASS. STAMBAUGH IN IRON COUNTY WAS THE COLD SPOT
IN THE MORNING ON BOTH 2/2 AND 2/3, REPORTING MINIMUM TEMPERATURES
OF -12 AND -10 RESPECTIVELY.

AN APPROACHING HIGH PRESSURE RIDGE ENDED THE LAKE EFFECT SNOWS
DURING THE NIGHT ON 2/3-2/4, WHEN SKIES CLEARED. FOR THE THIRD
MORNING IN A ROW, STAMBAUGH WAS THE COLDEST LOCATION, REPORTING THE
MONTHLY LOW TEMPERATURE OF -22 IN THE EARLY MORNING ON 2/4 AS THE
COMBINATION OF THE CLEAR SKIES AND LIGHT WINDS UNDER THE PASSING
RIDGE ALLOWED FOR SIGNIFICANT COOLING. CLOUDS BEGAN TO THICKEN AGAIN
ON 2/4 AHEAD OF A LOW PRESSURE SYSTEM MOVING FROM MINNESOTA TOWARD
LAKE SUPERIOR. THERE WAS A PERIOD OF SNOW THROUGH 2/4 THAT DROPPED 1
TO 4 INCHES OF THE WHITE STUFF ACROSS UPPER MICHIGAN, WITH THE
HIGHER TOTALS OVER THE EAST DOWNWIND OF LAKE MICHIGAN. FOLLOWING THE
PASSAGE OF THIS LOW, SOME LAKE EFFECT SNOW SHOWERS THAT FELL ON 2/5
DROPPED 1 TO 3 INCHES OF SNOW AS NORTHWEST WINDS GUSTING AS HIGH AS
35 MPH ADVECTED COLDER AIR OVER THE RELATIVELY WARM WATERS OF LAKE
SUPERIOR BEFORE AN APPROACHING HIGH PRESSURE RIDGE ENDED THIS
PRECIPITATION IN THE AFTERNOON OF 2/5. ANOTHER QUICK MOVING LOW
PRESSURE SYSTEM STREAKING THROUGH THE UPPER LAKES DEPOSITED A FEW
INCHES OF SNOW OVER MAINLY THE NORTHERN U.P. DURING THE NIGHT OF 2/5-
2/6 AND THE MORNING ON 2/6. THE THERMOMETER AVERAGED WITHIN A FEW
DEGREES OF NORMAL ON EACH DAY FROM 2/4 THROUGH 2/6.

A DEEPER LOW PRESSURE CENTER MOVING FROM NEAR CHICAGO THROUGH
NORTHERN LOWER MICHIGAN BROUGHT A PERIOD OF MODERATE TO HEAVY SNOW
TO UPPER MICHIGAN ON 2/7. THE HEAVIEST SNOW FELL ACROSS THE NORTHERN
TIER, WHERE SEVERAL PLACES REPORTED 10 INCHES OR MORE BEFORE THE
PRECIPITATION DIMINISHED TO SOME LAKE EFFECT SNOW SHOWERS DURING THE
NIGHT ON 2/7-2/8. SOME OF THE MORE IMPRESSIVE TOTALS INCLUDE 14.2
INCHES AT PAINESDALE IN HOUGHTON COUNTY AND 11 INCHES AT CHATHAM IN
ALGER COUNTY AS WELL AS IRONWOOD. OVER THE SOUTH, THE PRESENCE OF
DRIER AIR AND WARMER TEMPERATURES THAT CAUSED SOME MIXED
PRECIPITATION RESULTED IN MUCH LESS SNOWFALL THAT WAS UNDER AN INCH
IN AN AREA FROM IRON MOUNTAIN TO ESCANABA AND MANISTIQUE. BEHIND THE
EXITING LOW PRESSURE SYSTEM MOVING INTO QUEBEC, LAKE EFFECT SNOW
SHOWERS PERSISTED INTO THE EARLY MORNING HOURS ON 2/10, MAINLY IN
THE WEST TO NORTHWEST WIND SNOW BELTS DOWNWIND OF LAKE SUPERIOR.
SEVERAL LOCATIONS PICKED UP AN ADDITIONAL 3 TO 5 INCHES OF FLUFFY
SNOW, WITH UP TO ALMOST 9 INCHES MORE FALLING AT PAINESDALE FROM 2/8
INTO EARLY 2/10. OVER THE SOUTH CENTRAL, THE WEATHER WAS PARTLY
CLOUDY AND COLD, WITH WIND CHILLS AS LOW AS 20 TO 25 BELOW ZERO IN
THE MORNING ON 2/9. MEAN DAILY TEMPERATURES THAT RAN AROUND 5
DEGREES ABOVE NORMAL ON 2/7 DROPPED OFF TO 5 TO 10 DEGREES BELOW
AVERAGE ON 2/8 AND 2/9 WITHIN THE INCOMING ARCTIC AIRMASS.

A LOW PRESSURE CENTER MOVING QUICKLY FROM THE NORTHERN PLAINS
THROUGH THE UPPER LAKES BROUGHT A MIX OF SNOW, SLEET AND FREEZING
RAIN TO MAINLY THE NORTHEAST HALF OF UPPER MICHIGAN DURING THE
MORNING ON 2/10. BY THE TIME A TRAILING WEAK HIGH PRESSURE RIDGE
BUILT INTO THE UPPER GREAT LAKES AND BROUGHT A RETURN OF SOME
SUNSHINE IN THE AFTERNOON, AS MUCH AS 4 INCHES OF SNOW HAD
ACCUMULATED FROM GRAND MARAIS TO NEWBERRY. THERE WAS ALSO A THIN
GLAZE OF ICE AT MANY PLACES, WHICH RESULTED IN NUMEROUS TRAFFIC
ACCIDENTS IN THE MARQUETTE AREA. ALTHOUGH THE WEAK HIGH PRESSURE
BROUGHT DRY WEATHER ON 2/11, THERE WERE PLENTY OF LOW CLOUDS. NEAR
AVERAGE TEMPERATURES ON 2/10 REBOUNDED TO ABOUT 10 DEGREES ABOVE
NORMAL ON 2/11.

A PERIOD OF LIGHT SNOW, WHICH WAS MIXED WITH SOME LIGHT FREEZING
RAIN OVER THE WEST, ACCOMPANIED THE PASSAGE OF A LOW PRESSURE
SYSTEM ACROSS ONTARIO AND ITS ATTENDANT COLD FRONTAL PASSAGE ON
2/12. ALTHOUGH MOST PLACES OVER THE WEST AND CENTRAL SAW NO MORE
THAN 1 TO 2 INCHES OF SNOW, AS MUCH AS 3 TO 5 INCHES FELL OVER THE
EAST. AS WAS THE CASE ON 2/10, THE HIGHEST TOTALS FELL IN AN AREA
FROM MUNISING AND GRAND MARAIS TO NEWBERRY. THE ARRIVAL OF DRIER AIR
BEHIND THE COLD FRONT ENDED THE LARGER SCALE PRECIPITATION IN THE
AFTERNOON, BUT SOME LAKE EFFECT SNOW SHOWERS PERSISTED INTO THE
EVENING NEAR LAKE SUPERIOR. NORTHWEST WINDS GUSTING AS HIGH AS 40 TO
50 MPH CAUSED CONSIDERABLE BLOWING SNOW. AS HIGH PRESSURE BUILT INTO
THE AREA DURING THE NIGHT ON 2/12-2/13, THE WINDS AND BLOWING SNOW
DIMINISHED AND SKIES CLEARED. FOLLOWING THE PASSAGE OF THE HIGH
PRESSURE RIDGE ON 2/13, STEADY SOUTHWEST WINDS ADVECTED MUCH WARMER
AIR INTO THE UPPER GREAT LAKES. WITH A GOOD DEAL OF SUNSHINE, THE
MERCURY CLIMBED INTO THE 40S AWAY FROM THE COOLING INFLUENCE OF LAKE
MICHIGAN AND AS HIGH AS 50 AT PELKIE IN BARAGA COUNTY. MEAN DAILY
TEMPERATURES ON 2/12 AND 2/13 RANGED FROM 5 TO 15 DEGREES ABOVE
NORMAL.

A WEAK LOW PRESSURE TROUGH BROUGHT SOME LIGHT RAIN AND SNOW SHOWERS
TO THE U.P. DURING THE NIGHT ON 2/13-2/14 ALONG WITH WEST WINDS
GUSTING AS HIGH AS 35 MPH. A COLD FRONT SWUNG ACROSS THE AREA ON
VALENTINE`S DAY ACCOMPANIED BY SOME SCATTERED SNOW SHOWERS. THESE
SNOW SHOWERS BECAME MORE NUMEROUS OVER THE NORTHERN TIER WITH A WIND
SHIFT TO THE NORTHWEST AND ARRIVAL OF SOMEWHAT COLDER AIR. WINDS
GUSTED AS HIGH AS 40 TO 50 MPH THROUGH THE EVENING ON 2/14, CAUSING
SOME BLOWING SNOW. SNOW ACCUMULATIONS WERE GENERALLY NO MORE THAN 1
TO 2 INCHES THROUGH DAYBREAK ON 2/15 EVEN NEAR LAKE SUPERIOR. THE
LAKE EFFECT SNOWS PERSISTED IN THE FAVORED SNOW BELTS NEAR LAKE
SUPERIOR INTO THE EARLY MORNING ON 2/16, WHEN AN APPROACHING HIGH
PRESSURE IN ONTARIO ENDED THIS PRECIPITATION AND BROUGHT SOME
CLEARING. ADDITIONAL SNOW ACCUMULATIONS BETWEEN SUNRISE ON 2/15 AND
EARLY 2/16 ADDED UP TO AS MUCH AS 3 TO 5 INCHES IN THE FAVORED AREAS
FROM MUNISING TO GRAND MARAIS AND NEWBERRY. THE CLEARING DURING THE
EARLY MORNING ON 2/16 AND LIGHT WINDS UNDER THE APPROACHING HIGH
PRESSURE RIDGE ALLOWED TEMPERATURES TO FALL AS LOW AS -10 AT
CLARKSBURG IN MARQUETTE COUNTY. MEAN DAILY TEMPERATURES RANGING
BETWEEN 10 AND 15 DEGREES ABOVE AVERAGE ON 2/14 FELL TO WITHIN A FEW
DEGREES OF NORMAL ON 2/15 AND 2/16.

AFTER THE SURFACE HIGH PRESSURE SHIFTED TO THE EAST ON 2/16 AND AN
UPPER RIDGE BUILT OVER CENTRAL NORTH AMERICA, A SOUTH WIND ADVECTED
WARMER AIR INTO THE WESTERN GREAT LAKES. FOLLOWING THE PASSAGE OF A
WARM FRONT EARLY ON 2/17 THAT WAS PRECEDED BY ONLY SOME CLOUDS,
TEMPERATURES DURING A MOSTLY SUNNY AFTERNOON SURGED INTO RECORD
TERRITORY AT SOME PLACES, REACHING THE 50S AWAY FROM THE
MODERATING INFLUENCE OF THE GREAT LAKES, MAINLY LAKE MICHIGAN.
AT A COUPLE LOCATIONS OVER THE WEST, THE THERMOMETER PEAKED
AROUND 60, WITH READINGS AS HIGH AS 61 AT WAKEFIELD IN GOGEBIC
COUNTY AND KENTON IN FAR SOUTHERN HOUGHTON COUNTY. AFTER THE
MERCURY HELD ABOVE FREEZING DURING THE NIGHT ON 2/17-2/18 AT
MANY PLACES, SOME RECORD WARMTH CONTINUED ON 2/18 AWAY FROM THE
COOLING INFLUENCE OF LAKE SUPERIOR ACROSS THE WEST FOLLOWING THE
EARLY PASSAGE OF A COLD FRONT AND A WIND SHIFT TO THE NORTHWEST WITH
WINDS GUSTING AS HIGH AS 40 MPH. TEMPERATURES SURGED TO OR ABOVE 60
AT MANY PLACES OVER THE SOUTH CENTRAL IN THE AFTERNOON ON 2/18,
REACHING THE MONTHLY HIGH OF 64 AT STONINGTON IN DELTA COUNTY. AT
NEWBERRY, THE 53-DEGREE MAXIMUM WAS NOT ONLY A RECORD FOR THE DATE
BUT ALSO FOR THE ENTIRE MONTH OF FEBRUARY. THE THERMOMETER RAN 15 TO
25 DEGREES ABOVE NORMAL ON 2/17 AND THEN AN INCREDIBLE 20 TO 30
DEGREES ABOVE AVERAGE ON 2/18. ALTHOUGH COOLER AIR FOLLOWED THE COLD
FRONTAL PASSAGE, THE INCOMING AIRMASS WAS STILL PACIFIC IN ORIGIN,
SO HIGH TEMPERATURES STILL REACHED THE 50S AT MANY PLACES ON 2/19,
PEAKING AS HIGH AS 59 AT WATERSMEET IN GOGEBIC COUNTY UNDER PARTLY
TO MOSTLY SUNNY SKIES. THE MERCURY RAN 15 TO 25 DEGREES ABOVE NORMAL
ON 2/19.

A STEADY SOUTH WIND BETWEEN A DEPARTING HIGH PRESSURE RIDGE AND LOW
PRESSURE TRACKING NORTH THROUGH THE PLAINS TOWARD SOUTH CENTRAL
CANADA DURING THE NIGHT ON 2/19-2/20 RESULTED IN SOME RECORD WARM
OVERNIGHT LOWS OVER THE WEST, INCLUDING A 43-DEGREE MINIMUM REPORTED
NEAR IRONWOOD. CLOUDS THICKENED AHEAD OF AN APPROACHING WARM FRONT
ASSOCIATED WITH THE PLAINS LOW ON 2/20, BUT HIGH TEMPERATURES STILL
REACHED THE LOW 50S AT SEVERAL PLACES ACROSS THE WEST. SHOWERS AHEAD
OF THE WARM FRONT PASSED ACROSS THE AREA DURING THE NIGHT ON 2/20-
2/21, DROPPING 0.10 TO 0.50 INCH OF RAIN AT MANY LOCATIONS AND AS
MUCH AS 0.69 INCH NEAR WATERSMEET. AFTER THE LOW MOVED THROUGH
NORTHWEST ONTARIO AND ITS COLD FRONT PASSED DURING THE MORNING OF
2/21, LINGERING SHOWERS ENDED AND SKIES CLEARED, SETTING THE STAGE
FOR MORE RECORD WARMTH AS THE TRAILING AIRMASS WAS A PACIFIC ONE.
THE MERCURY SURGED ABOVE 60 AT A FEW MORE LOCATIONS IN THE AFTERNOON
ON 2/21, WITH READINGS REACHING AS HIGH AS 61 AT RANDVILLE IN
DICKINSON COUNTY. MEAN DAILY TEMPERATURES WERE 15 TO 25 DEGREES
ABOVE NORMAL ON 2/20 AND THEN AROUND AN INCREDIBLE 30 DEGREES ABOVE
AVERAGE ON 2/21.

A PAIR OF LOW PRESSURE SYSTEMS RUNNING NORTHEAST FROM THE PLAINS
THROUGH MINNESOTA ON THE EASTERN FLANK OF A SLOWLY DEEPENING UPPER
TROUGH IN THE PLAINS BROUGHT MORE SHOWERS TO THE AREA BEGINNING
THE NIGHT OF 2/21-2/22, WHEN MINIMUM TEMPERATURES HELD NEAR 40 AT A
FEW PLACES NEAR THE GREAT LAKES. AFTER THE SECOND LOW PASSED INTO
ONTARIO DURING THE NIGHT ON 2/22-2/23 AND DRAGGED A COLD FRONT
THROUGH THE UPPER LAKES, THE RAIN SHOWERS CHANGED TO SNOW OVER ALL
BUT THE FAR SOUTHEAST U.P. THE PRECIPITATION ENDED SOON AFTER
DAYBREAK ON 2/23, BUT NOT BEFORE SNOW TOTALS REACHED AS MUCH AS 3 TO
6 INCHES IN A BAND FROM NEAR WATERSMEET TO NEGAUNEE IN MARQUETTE
COUNTY. LIQUID PRECIPITATION TOTALS VARIED FROM ONLY AROUND 0.10
INCH OVER THE KEWEENAW TO AS MUCH AS ABOUT 0.75 INCH OVER THE HIGHER
TERRAIN OF THE NORTH CENTRAL. BEHIND THE COLD FRONT, THE DAY ON 2/23
WAS MOSTLY CLOUDY AND COLDER, BUT STILL WARMER THAN NORMAL. AFTER
THE MERCURY AVERAGED AROUND 25 DEGREES ABOVE NORMAL ON 2/22,
READINGS WERE A MORE MODERATE 10 TO 20 DEGREES ABOVE AVERAGE ON 2/23.

A DEEPER LOW PRESSURE SYSTEM TRACKING NORTHEAST OUT OF THE UPPER
TROUGH IN THE PLAINS THEN BROUGHT A ROUND OF MODERATE TO HEAVY
PRECIPITATION TO UPPER MICHIGAN ON 2/24 INTO 2/25. WHILE MOST OF
THIS FELL IN THE FORM OF SNOW, THERE WAS A WINTRY MIX WITH SOME
SLEET AND LIGHT FREEZING RAIN OVER THE EAST HALF. BY THE TIME THE
PRECIPITATION DIMINISHED DURING THE AFTERNOON ON 2/25, 10 INCHES OR
MORE OF SNOW HAD ACCUMULATED OVER THE HIGHER TERRAIN OF THE
NORTHWEST HALF. PAINESDALE REPORTED THE MOST SNOW WITH 13.8 INCHES.
HERMAN IN BARAGA COUNTY, BERGLAND DAM IN ONTONAGON COUNTY, AND
ATLANTIC MINE IN HOUGHTON COUNTY ALSO HAD A FOOT OR MORE OF SNOW
WITH 13.0, 12.5, AND 12.0 INCHES RESPECTIVELY. LIQUID EQUIVALENT
PRECIPITATION WAS UP TO 0.50 TO 0.75 INCH AT THESE HIGHER TERRAIN
LOCATIONS. MANISTIQUE REPORTED BOTH THE LEAST SNOW AND WATER
EQUIVALENT PRECIPITATION WITH 1.1 INCHES AND 0.27 INCH.
FOLLOWING THE PASSAGE OF THE LOW TO THE NORTHEAST AND AHEAD OF AN
APPROACHING HIGH PRESSURE RIDGE IN THE PLAINS, NORTHWEST WINDS
GUSTED AS HIGH AS 45 MPH AT GRAND MARIAS ON 2/25, RESULTING IN SOME
BLOWING SNOW. MEAN DAILY TEMPERATURES AVERAGED AROUND 5 DEGREES
ABOVE NORMAL ON 2/24 THEN FELL TO A COUPLE DEGREES BELOW NORMAL ON
2/25 AS SOME COLDER AIR FOLLOWED THE DEPARTING LOW PRESSURE SYSTEM.

A PASSING UPPER DISTURBANCE AND COLD FRONT BROUGHT A MIX OF SOME
LIGHT RAIN AND SNOW SHOWERS TO THE AREA ON 2/26, BUT THESE CHANGED
TO MAINLY SNOW SHOWERS DURING THE AFTERNOON AND EVENING AS COLDER
AIR FOLLOWED THE FRONT INTO THE AREA. A FEW LOCATIONS OVER THE HURON
MOUNTAINS IN THE NORTH CENTRAL REPORTED A COUPLE OF INCHES OF SNOW,
INCLUDING AS MUCH AS 3 TO 5 INCHES BETWEEN BIG BAY IN MARQUETTE
COUNTY AND HERMAN. SKIES CLEARED DURING THE NIGHT ON 2/26-2/27 AS A
WEAK HIGH PRESSURE RIDGE DRIFTED OVER THE UPPER LAKES. LIGHT WINDS
ALLOWED TEMPERATURES TO PLUMMET TO AS LOW AS -12 AT CLARKSBURG AND
WAKEFIELD. THEN CLOUDS INCREASED QUICKLY AHEAD OF AN APPROACHING
WARM FRONT, AND SOME PATCHY LIGHT SNOW ALSO FELL ACROSS THE WEST
DURING THE AFTERNOON ON 2/27 AS TEMPERATURES MODERATED FROM THE
EARLY MORNING CHILL. THE NIGHT OF 2/27-2/28 WAS DRY WITH PARTLY TO
MOSTLY CLOUDY SKIES AND PATCHY FOG OVER MAINLY THE SOUTHEAST HALF.
AS A COLD FRONT APPROACHED ON 2/28, THERE WERE PERIODS OF LIGHT SNOW
THAT MIXED WITH RAIN OVER THE SOUTHEAST.

                             APRIL FORECAST

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

                           APRIL CLIMATOLOGY

AS THE SUN CONTINUES ITS MARCH NORTHWARD DURING THE FOURTH MONTH OF
THE YEAR...DAYLIGHT AND AVERAGE TEMPERATURES INCREASE STEADILY. THE
DAILY POSSIBLE SUNSHINE INCREASES FROM 769 MINUTES ON 4/1 TO 860
MINUTES ON THE LAST DAY OF THE MONTH. ON 4/1...NORMAL MAXIMUM AND
MINIMUM TEMPERATURES AT THE MARQUETTE NWS ARE 41 AND 21...BUT
REBOUND TO 55 AND 35 ON 4/30. MONTHLY AVERAGE TEMPERATURES
THROUGHOUT UPPER MICHIGAN ARE 12 TO 14 DEGREES HIGHER IN APRIL THAN
IN MARCH. THE RELATIVELY COOL WATERS OF THE GREAT LAKES OFTEN KEEP
TEMPERATURES NEAR THE SHORE DURING THE DAY MUCH LOWER THAN FARTHER
INLAND.

AVERAGE PRECIPITATION IN APRIL IS GREATER THAN IN MARCH OVER MUCH OF
INTERIOR UPPER MICHIGAN...BUT GENERALLY LESS IN AREAS NEAR LAKE
SUPERIOR AS THE RELATIVELY COOL WATERS INCREASE LOW LEVEL STABILITY
AND REDUCE THE THREAT OF LAKE EFFECT SNOW AND CONVECTIVE SHOWERS.
SNOWFALL DURING WARM AND/OR DRY APRILS ACROSS UPPER MICHIGAN IS
OFTEN LESS THAN AN INCH.

SUMMER-LIKE WEATHER CAN OCCUR DURING APRIL. RECORD HIGH TEMPERATURES
NEAR THE END OF THE MONTH GO ABOVE 90 IN SOME LOCATIONS...INCLUDING
THE 94 AND 92 DEGREE READINGS OBSERVED AT IRON MOUNTAIN AND THE
MARQUETTE NWS ON 4/22/80. ALTHOUGH APRIL 1987 IS THE WARMEST ON
RECORD OR AT LEAST IN THE TOP FIVE WARMEST AT MANY PLACES...THE
SECOND HALF OF APRIL 1990 STANDS OUT AS A PERIOD OF UNPRECEDENTED
WARMTH. IN FACT...THE WEEK BETWEEN 4/22/90 AND 4/29/90 IS THE
WARMEST ON RECORD AT ALL REPORTING STATIONS. TEMPERATURES DURING
THIS WEEK AVERAGED AS HIGH AS 68 AT MUNISING AND THE MARQUETTE
NWS...67 AT ONTONAGON...65 AT IRON MOUNTAIN...IRONWOOD AND
MANISTIQUE...64 AT HOUGHTON AND 62 AT NEWBERRY. AT MANY OF THESE
SITES... THE HIGHEST APRIL TEMPERATURE ON RECORD OCCURRED DURING
THIS WEEK...INCLUDING 89 AT MUNISING (4/26/90) AND ONTONAGON
(4/25/90)...88 AT HOUGHTON (4/25/90)...84 AT MANISTIQUE (4/26/90)
AND 82 AT NEWBERRY (4/25/90). SEVEN OF THE 10 HIGHEST APRIL MAXIMUM
TEMPERATURES RECORDED AT MANISTIQUE OCCURRED BETWEEN 4/23/90 AND
4/29/90. ALL OF THESE TEMPERATURES WOULD BE CONSIDERED NORMAL OR
EVEN ABOVE NORMAL DURING MID SUMMER.

WHEN APRIL TEMPERATURES SOAR QUICKLY WITH LINGERING DEEP WINTER SNOW
COVER...SNOWMELT CAN CAUSE SERIOUS FLOODING...ESPECIALLY IF HEAVY
RAINS FALL AROUND THE TIME OF WARMUP. IN 2002...THE COMBINATION OF
DEEP EARLY APRIL SNOW COVER AND A FEW DAYS OF HEAVY RAIN BEFORE
TEMPERATURES WARMED AS HIGH AS 80 TO 85 CAUSED DISASTROUS MID-APRIL
FLOODING IN WESTERN UPPER MICHIGAN. THE FLOODING WAS SO BAD IN
GOGEBIC COUNTY THEN MICHIGAN GOVERNOR JOHN ENGLER DECLARED THAT
COUNTY A DISASTER AREA AND DISPATCHED MICHIGAN NATIONAL GUARD TROOPS
TO ASSIST WITH RECOVERY. ALTHOUGH SEVERE WEATHER IS UNCOMMON ACROSS
UPPER MICHIGAN IN APRIL...AN OUTBREAK OF EARLY SEASON SEVERE
THUNDERSTORMS ENDED THIS PREMATURE SUMMER WARMTH IN APRIL 2002.

ALTHOUGH AVERAGE TEMPERATURES CLIMB QUICKLY IN APRIL AND SUMMER-LIKE
HEAT SOMETIMES HERALDS THE COMING WARM SEASON...WINTER CAN RETURN
WITH A VENGEANCE EVEN AT MONTHS END. FOR STATIONS WITH A LONGER TERM
RECORD...APRIL 1907 STANDS OUT AS THE COLDEST ON RECORD AT IRONWOOD
AND HOUGHTON. AT HOUGHTON...THE MEAN MONTHLY TEMPERATURE THAT MONTH
WAS A WINTER-LIKE 27.9 DEGREES. APRIL 1950 WAS THE COLDEST FOURTH
MONTH ON RECORD AT NEWBERRY...IRON MOUNTAIN AND MUNISING. MORE
RECENTLY...APRIL IN 2013 AND 2014 FEATURED PERIODS OF VERY COLD
WEATHER AND RANK AMONG THE TOP FIVE COLDEST AT SOME PLACES. RECORD
LOW TEMPERATURES IN APRIL ARE BELOW ZERO AT MOST LOCATIONS. THE
MERCURY FELL AS LOW AS -12 AT IRONWOOD ON 4/7/82. SUB-ZERO MINIMUMS
HAVE OCCURRED EVEN AFTER MID MONTH AT SOME LOCATIONS...INCLUDING -8
AT IRONWOOD ON 4/17/83 AND -7 AT CLARKSBURG/CHAMPION IN MARQUETTE
COUNTY ON 4/16/2014.

RECORD HIGH APRIL SNOWFALL AT ALMOST ALL LOCATIONS EXCEPT THE
SOUTHERN TIER COUNTIES IS 20 INCHES OR MORE. A HISTORIC BLIZZARD
STRUCK THE NORTHERN COUNTIES OF UPPER MICHIGAN ON 4/3 INTO 4/8 IN
2007. THE COMBINATION OF LAKE ENHANCED SNOW AND NORTH WIND GUSTS AT
OR ABOVE 50 MPH CAUSED WIDESPREAD BLIZZARD CONDITIONS ON 4/4 AND 4/5
THAT YEAR NEAR LAKE SUPERIOR. BY THE TIME THE SNOW ENDED EARLY ON
4/8/2007...AS MUCH AS 59.0 INCHES HAD FALLEN AT PAINESDALE IN
HOUGHTON COUNTY. IN APRIL 2013...A PERSISTENT AND DEEP UPPER TROUGH
OVER CENTRAL AND EASTERN NORTH AMERICA RESULTED IN STUBBORN CHILL
UNTIL THE LAST WEEK OF THE MONTH AND SEVERAL HEAVY SNOW FALLS THAT
