...GREAT LAKES WATER LEVELS REMAIN NEARLY STEADY IN FEBRUARY...

DUE TO THE RECORD COLD WEATHER IN DECEMBER THROUGH FEBRUARY...LAKE
SUPERIOR AND MUCH OF NORTHERN LAKE MICHIGAN WERE ALMOST COMPLETELY
ICE COVERED BY THE END OF FEBRUARY. EVEN THOUGH THERE IS NORMALLY A
SLOW DECLINE IN WATER LEVELS ON LAKES SUPERIOR AND MICHIGAN/HURON IN
FEBRUARY...THE GROWING ICE COVER AND/OR A NEAR ABSENCE OF
EVAPORATION IN THE PERSISTENTLY COLD WEATHER PATTERN CAUSED THE
LAKES TO REMAIN NEARLY STEADY IN FEBRUARY. BUT AT THE END OF
FEBRUARY...LAKES MICHIGAN/HURON WERE STILL ALMOST 13 INCHES UNDER
THE LONG TERM AVERAGE...WHILE LAKE SUPERIOR WAS ABOUT AN INCH BELOW
NORMAL. COMPARED TO THE END OF FEBRUARY IN 2013...THE LEVEL ON LAKES
MICHIGAN/HURON WAS ABOUT 14 INCHES HIGHER ON 2/28 IN 2014. LAKE
SUPERIOR WAS AT ALMOST THE SAME LEVEL IN FEBRUARY 2014 AS IN 2013.

LOWEST MONTHLY SNOWFALL...10.5 INCHES AT MANISTIQUE


THE VERY RESILIENT UPPER AIR PATTERN FEATURING A TROUGH OVER EASTERN
NORTH AMERICA DOWNSTREAM OF A RIDGE OVER THE WEST PERSISTED MOST OF
THE TIME THROUGH FEBRUARY 2014...ALLOWING AN ALMOST CONTINUOUS
STREAM OF COLD CANADIAN AIR TO DOMINATE UPPER MICHIGAN WEATHER
DURING THE MONTH. THE RESULT WAS A TOP FIVE COLDEST FEBRUARY AT MOST
LOCATIONS...WITH A MEAN MONTHLY TEMPERATURE BETWEEN 1 AND 11 DEGREES
AVERAGING 9 TO AS MUCH AS 12 DEGREES BELOW THE LONG TERM FEBRUARY
AVERAGE. THE MEAN FEBRUARY TEMPERATURE ENDED UP WITHIN ABOUT THREE
DEGREES OF THE JANUARY AVERAGE. AT THE MARQUETTE NWS OFFICE WHERE
WEATHER OBSERVATIONS DATE BACK TO ONLY 1961...FEBRUARY 2014 IS NOW
THE COLDEST FEBRUARY ON RECORD.

EXCEPT FOR A COUPLE OF DAYS CENTERED AROUND 2/19 WHEN THE DEEP
EASTERN TROUGH BRIEFLY GAVE WAY TO A MORE ZONAL PACIFIC FLOW...THE
MEAN DAILY TEMPERATURE EVERY DAY IN FEBRUARY WAS BELOW AVERAGE.
DURING THE COLDEST TIMES FROM 2/1 THROUGH 2/11...2/15 TO 2/17...AND
2/23 THROUGH 2/28...THE MERCURY AVERAGED 10 TO 20 AND EVEN MORE
BELOW NORMAL EACH DAY. THE COLDEST CANADIAN AIRMASS INVADED AT THE
END OF FEBRUARY...WHEN THE MEAN DAILY TEMPERATURE WAS AROUND 30
DEGREES BELOW AVERAGE ON 2/27 AND 2/28. NUMEROUS DAILY RECORD LOW
MINIMUM AND MAXIMUM TEMPERATURE FELL BY THE WAYSIDE ON THESE TWO
COLDEST DAYS. AT MANY PLACES...THE HIGH TEMPERATURE ON 2/27 DID NOT
GET ABOVE ZERO. MINIMUM TEMPERATURES ON BOTH 2/27 AND 2/28 SANK PAST
20 BELOW AT MANY SPOTS ON THESE DAYS AND EVEN UNDER 30 BELOW AT SOME
OF THE COLDEST LOCATIONS ON 2/28. A LOCATION NEAR NEWBERRY REPORTED
THE LOWEST TEMPERATURE OF -41 ON 2/28. IN ADDITION TO 2/27 AND
2/28...THE MERCURY SANK TO -20 OR LOWER AT AT LEAST A FEW LOCATIONS
ON 2/1...2/3...2/4...2/8...2/10...2/11...2/15 AND 2/26. SOME COLDER
PLACES REPORTED A LOW TEMPERATURE AT OR BELOW -30 ON 2/3...2/11 AS
WELL AS 2/28. DURING THE BRIEF WARMUP AT THE END OF THE THIRD WEEK
OF THE MONTH...THE THERMOMETER PEAKED AT 40 OR HIGHER AT SOME SITES
IN THE AFTERNOON ON 2/18...2/19 AND 2/20. AT SOME LOCATIONS...THESE
WARMER DAYS MARKED THE FIRST TIME SINCE EARLY DECEMBER THE MERCURY
ROSE ABOVE 32. AT THE MARQUETTE NWS...THERE WAS A RECORD 75
CONSECUTIVE DAYS BETWEEN 12/5/13 AND 2/19/14 WHEN TEMPERATURES DID
NOT RISE ABOVE THE FREEZING MARK.

LOW TEMPERATURES AT OR BELOW ZERO WERE COMMON MOST OF THE MONTH THANKS
TO THE DOMINANCE OF DRIER CANADIAN AIRMASSES...ABUNDANT SNOW COVER
AND ALSO TO THE EXTENSIVE ICE COVER THAT DEVELOPED ON THE GREAT
LAKES DUE TO THE TENACIOUS COLD THAT HAD BEEN IN PLACE SINCE LATE
AUTUMN. IN FACT...THE NUMBER OF DAYS WHEN THE THERMOMETER DIPPED TO
ZERO OR BELOW IN FEBRUARY SET A RECORD AT SOME PLACES. AT IRON
MOUNTAIN AND MANISTIQUE...WHERE RECORDS DATE BACK INTO THE 1890S...
THE LOW TEMPERATURE IN FEBRUARY 2014 WAS ZERO OR BELOW A RECORD 22
DAYS AND 19 DAYS RESPECTIVELY. THE MINIMUM TEMPERATURE AT THE
MARQUETTE NWS FELL TO ZERO OR BELOW ON 20 OF THE 28 DAYS...TYING THE
MONTH WITH FEBRUARY IN 1989 AND 1979 FOR THE MOST OCCURRENCES OF
THOSE VERY LOW TEMPERATURES SINCE OBSERVATIONS BEGAN AT THAT SITE IN
1961. THE COMBINATION OF THE VERY COLD WEATHER THAT DOMINATED IN
DECEMBER AND JANUARY AS WELL AS ALL THIS SUB ZERO CHILL IN FEBRUARY
CAUSED THE FROST DEPTH TO DESCEND FARTHER INTO THE GROUND THAN
USUAL. THE RESULT WAS A FREEZING OF SHALLOWER WATER PIPES AND
DISRUPTION OF WATER SERVICE TO MANY HOMES ACROSS THE U.P. IN
FEBRUARY.

ALTHOUGH THE GENERAL NORTHWEST FLOW ALOFT TENDED TO SUPPRESS MOST OF
THE MOISTURE LADEN...LARGER SCALE LOW PRESSURE SYSTEMS TO THE SOUTH
OF UPPER MICHIGAN AND GROWING ICE COVER ON LAKE SUPERIOR TENDED TO
DIMINISH THE COVERAGE AND INTENSITY OF LAKE EFFECT SNOW SHOWERS...
MOST OF WESTERN AND SOUTH CENTRAL UPPER MICHIGAN SAW ABOVE NORMAL
PRECIPITATION AND SNOWFALL IN FEBRUARY...AS MUCH AS 150 TO 175
PERCENT OF THE FEBRUARY AVERAGE. PAINESDALE IN HOUGHTON COUNTY LED
REPORTING STATIONS WITH 52 INCHES OF SNOW. THE NORTH CENTRAL AND
EAST TENDED TO BE DRIER WITH BELOW AVERAGE SNOWFALL. SOME PLACES IN
THIS AREA REPORTED AS LITTLE AS 50 TO 75 PERCENT OF THE TYPICAL
FEBRUARY NUMBERS.

TWO ALBERTA CLIPPER TYPE LOW PRESSURE SYSTEMS OF SIGNIFICANCE DUMPED
LIGHT TO MODERATE SNOW ON UPPER MICHIGAN IN FEBRUARY. THE FIRST OF
THESE TRACKED THROUGH THE UPPER MIDWEST ON 2/13 INTO 2/14. SNOWFALL
WAS GENERALLY 4 TO 8 INCHES EXCEPT OVER THE SOUTH CENTRAL...WHERE
ONLY 2 TO 4 INCHES ACCUMULATED. GUSTY NORTH WINDS UP TO 35 TO 40 MPH
IN THE WAKE OF THE LOW TRACKING TO THE EAST CAUSED A GOOD DEAL OF
BLOWING SNOW NEAR LAKE SUPERIOR THROUGH THE MORNING ON 2/14. THE
SECOND DISTURBANCE DROPPED 2 TO 4 INCHES OF THE WHITE STUFF AT MOST
PLACES ON 2/17 INTO EARLY 2/18. PAINESDALE LED REPORTING STATIONS
WITH NEAR 5 INCHES.

THE ONE MOISTER AND DEEPER LOW PRESSURE SYSTEM THAT MOVED NORTHEAST
FROM THE PLAINS AND IMPACTED THE UPPER GREAT LAKES IN FEBRUARY
OCCURRED ON 2/20 INTO 2/21. SINCE THE LOW PRESSURE CENTER MOVED
THROUGH NORTHWEST WISCONSIN AND ACROSS THE WESTERN U.P....THE
HEAVIEST WATER EQUIVALENT PRECIPITATION AND SNOW FELL OVER THE
WEST...WHERE ATLANTIC MINE IN HOUGHTON COUNTY MEASURED 0.90 INCH AND
9.0 INCHES RESPECTIVELY. THE SOUTHERLY FLOW EAST OF THE LOW TRACK
DRAGGED WARMER AIR INTO THE EAST HALF OF UPPER MICHIGAN...SO THE
LIGHTER PRECIPITATION THAT FELL WAS A WINTRY MIX OF SNOW...SLEET...
FREEZING RAIN AND RAIN ACROSS AREAS MAINLY EAST OF A LINE FROM
MARQUETTE TO IRON MOUNTAIN. ALTHOUGH THE SNOW DIMINISHED TO LIGHTER
LAKE EFFECT SNOW SHOWERS ON 2/21 ONCE THE LOW MOVED TO THE NORTH
AND INTO ONTARIO...THE COMBINATION OF DEEP SNOW AND STRONG WEST
WINDS THAT GUSTED AS HIGH AS 50 TO 60 MPH OVER THE KEWEENAW ON 2/22
CAUSED EXTENSIVE BLOWING SNOW AND BLIZZARD CONDITIONS THAT LINGERED
IN THAT AREA THROUGH 2/23 UNTIL THE ARRIVAL OF A HIGH PRESSURE RIDGE
AND LIGHTER WINDS ENDED THIS WINTRY ONSLAUGHT ON 2/24. MANY
SECONDARY ROADS IN HOUGHTON AND KEWEENAW COUNTIES BECAME IMPASSABLE
ON 2/21 THROUGH 2/23.

ALTHOUGH THE COLD FRONTAL PASSAGE DURING THE NIGHT ON 2/26-2/27 THAT
USHERED IN THE BITTERLY COLD AIRMASS TO END FEBRUARY WAS ACCOMPANIED
BY ONLY RELATIVELY LIGHT SNOW...NORTHWEST WINDS THAT GUSTED AS HIGH
AS 45 TO 55 MPH NEAR LAKE SUPERIOR CAUSED EXTENSIVE BLOWING SNOW AND
OCCASIONAL BLIZZARD CONDITIONS IN OPEN AREAS. M-28 BETWEEN HARVEY IN
MARQUETTE COUNTY AND MUNISING WAS CLOSED INTO THE AFTERNOON ON 2/27.
ALTHOUGH TEMPERATURES EARLY ON 2/27 WERE NOT EXCESSIVELY COLD YET...
THE GUSTY WINDS CAUSED WIND CHILLS TO FALL AS LOW AS -40 BY SUNRISE
ON 2/27.

                       FEBRUARY WEATHER SUMMARY

ALTHOUGH DISTURBANCES RIDING THROUGH THE NORTHWEST FLOW ALOFT AROUND
A DEEP...STATIONARY UPPER TROUGH CENTERED NEAR HUDSON BAY BROUGHT
SOME PERIODS OF CLOUDS AND SNOW SHOWERS TO MAINLY AREAS NEAR LAKE
SUPERIOR...THE PERIOD FROM 2/1 THROUGH 2/12 ACROSS UPPER MICHIGAN
WAS GENERALLY A DRY AND VERY COLD ONE DOMINATED BY CANADIAN HIGH
PRESSURE SYSTEMS. EVEN IN THE FAVORED NORTHWEST WIND SNOW BELTS...
THE DOMINANCE OF DRY AIRMASSES AND EXPANDING ICE COVER ON LAKE
SUPERIOR HELD TOTAL SNOW ACCUMULATIONS DURING THIS TIME TO NO MORE
THAN A COUPLE OF INCHES AROUND THE TROUGH PASSAGES ON 2/1...2/2-
2/3...2/4-2/5...2/8-2/9 AND 2/11-2/12. MEAN DAILY TEMPERATURES ON
2/1 THROUGH 2/12 RAN FROM AS MUCH AS 15 TO 20 DEGREES BELOW AVERAGE
ON THE COLDEST DAYS...WHICH INCLUDED 2/1...2/10 AND 2/11...TO 5 TO
10 DEGREES BELOW NORMAL DURING THE LESS HARSH PERIOD FROM 2/2
THROUGH 2/9 AND ON 2/12. BUT EVEN ON THESE MORE MODERATE DAYS...SUB
ZERO LOW TEMPERATURES WERE COMMON. SOME OF THE MORE NOTABLE MINIMUMS
WERE -25 JUST INLAND FROM MUNISING ON 2/1...-30 AT THIS SAME
LOCATION ON 2/3...-20 AT WAKEFIELD IN GOGEBIC COUNTY AND STONINGTON
IN DELTA COUNTY ON 2/4...-24 AT STAMBAUGH IN IRON COUNTY ON
2/8...-24 AT STAMBAUGH ON 2/10 AND -30 AT STAMBAUGH ON 2/11. THE
MERCURY BARELY RECOVERED ABOVE ZERO AT SOME PLACES OVER THE WEST ON
2/10...WHEN THE PEAK READING WAS ONLY 1 ABOVE ZERO AT IRONWOOD AND
HOUGHTON.

A STRONGER ALBERTA CLIPPER LOW PRESSURE SYSTEM TRACKED FROM THE
NORTHERN PLAINS ON 2/13 THROUGH NORTHERN WISCONSIN AND INTO
SOUTHEAST ONTARIO ON 2/14. STEADY SNOW ASSOCIATED WITH THIS
DISTURBANCE ARRIVED WEST-TO-EAST ON 2/13. ALTHOUGH THE PRECIPITATION
ENDED OVER THE SOUTH CENTRAL DURING THE NIGHT ON 2/13-2/24 AFTER THE
LOW DRIFTED TO THE EAST...LAKE EFFECT SNOW SHOWERS DEVELOPED ACROSS
THE NORTHERN TIER AS COLDER AIR SURGED BACK INTO THE UPPER LAKES ON
THE HEELS OF NORTH WINDS GUSTING AS HIGH AS 35 TO 40 MPH. THESE
STRONG WINDS ALSO CAUSED A GOOD DEAL OF BLOWING SNOW NEAR LAKE
SUPERIOR. BY THE TIME HIGH PRESSURE BUILT TOWARD THE AREA LATER ON
VALENTINE`S DAY AND CAUSED THE SNOW AND WINDS TO DIMINISH...AS MUCH
AS 4 TO 8 INCHES OF SNOW HAD ACCUMULATED AT MOST LOCATIONS OVER THE
NORTHERN TIER OF UPPER MICHIGAN. HERMAN IN BARAGA COUNTY LED
REPORTING STATIONS WITH 8.5 INCHES OF THE WHITE STUFF. SNOW TOTALS
OVER THE SOUTH CENTRAL WERE GENERALLY 2 TO 4 INCHES. MEAN DAILY
TEMPERATURES ON 2/13 AND 2/14 WERE AROUND 5 DEGREES BELOW AVERAGE.

AS THE TRAILING HIGH PRESSURE SYSTEM MOVED OVER UPPER MICHIGAN
DURING THE NIGHT ON 2/14-2/15...MOSTLY CLEAR SKIES AND LIGHT WINDS
SET THE STAGE FOR ANOTHER VERY COLD TIME. MORNING LOWS AT DAYBREAK
ON 2/15 DIPPED AS LOW AS -25 AT WAKEFIELD IN GOGEBIC COUNTY. ANOTHER
WEAKER CLIPPER LOW TRACKED ACROSS THE UPPER LAKES FROM LATE ON 2/15
INTO 2/16...DROPPING 1 TO 3 INCHES OF SNOW ON THE U.P. MORE LIGHT
SNOW IN ADVANCE OF A STRONGER CLIPPER DISTURBANCE AND LOW PRESSURE
SYSTEM TRACKING THROUGH GREAT LAKES ARRIVED WEST-TO-EAST OVER UPPER
MICHIGAN ON 2/17. BY THE TIME THE SNOW ENDED DURING THE NIGHT ON
2/17-2/18 WITH THE ARRIVAL OF A HIGH PRESSURE RIDGE...MOST PLACES
HAD PICKED UP 2 TO 4 INCHES OF SNOW. PAINESDALE IN HOUGHTON COUNTY
SAW NEARLY 5 INCHES. MEAN DAILY TEMPERATURES ON 2/15 THROUGH 2/17
RANGED FROM 10 TO 15 DEGREES BELOW AVERAGE.

ONCE THE HIGH PRESSURE RIDGE TRAILING THE DISTURBANCE RESPONSIBLE
FOR THE SNOW ON 2/17 SHIFTED TO THE EAST...A SOUTH TO SOUTHWEST
FLOW OF MILDER AIR BROUGHT A WELCOME RETURN OF WARMER WEATHER FOR A
COUPLE OF DAYS. WITH A GOOD DEAL OF SUNSHINE...THE THERMOMETER
REBOUNDED INTO THE 40S AT A NUMBER OF LOCATIONS OVER THE WEST ON
2/18 AND ALL THE WAY TO A BALMY 49 AT PELKIE IN BARAGA COUNTY.
ALTHOUGH SOME PATCHY DENSE FOG DEVELOPED OVER THE INTERIOR DURING
THE NIGHT ON 2/18-2/19...THE DAY ON 2/19 TURNED OUT MOSTLY SUNNY AND
WARM AGAIN WITH THE CONTINUED SOUTHWEST FLOW. HIGH TEMPERATURES
REACHED THE 40S AT MANY INTERIOR LOCATIONS AWAY FROM THE COOLING
INFLUENCE OF THE ICE COVERED GREAT LAKES...REACHING 47 AT RANDVILLE
IN DICKINSON COUNTY. AT THE MARQUETTE NWS IN MARQUETTE COUNTY...THE
MERCURY REACHED 41 DEGREES ON 2/19...WHICH WAS THE FIRST DAY THE
MAXIMUM TEMPERATURE AT THAT LOCATION WAS OVER 32 SINCE 12/5 AND OVER
40 SINCE 11/17. DESPITE SOME INCREASING CLOUDS ON 2/20 AHEAD OF A
DEEPENING LOW MOVING NORTHEAST FROM THE PLAINS...THE SOUTHWEST FLOW
AROUND THE HIGH PRESSURE SYSTEM MOVING INTO THE MID ATLANTIC STATES
BROUGHT MORE 40- DEGREE HIGH TEMPERATURES TO MANY LOCATIONS...
INCLUDING 46 AT GREENLAND IN ONTONAGON COUNTY AND PELKIE. MEAN DAILY
TEMPERATURES THAT RAN 5 TO 10 DEGREES ABOVE AVERAGE ON 2/18 ROSE TO
AROUND 15 DEGREES ABOVE NORMAL ON 2/19 AND 2/20.

THE MOST SIGNIFICANT LOW PRESSURE SYSTEM TO IMPACT THE UPPER GREAT
LAKES IN FEBRUARY MOVED NORTH THROUGH WISCONSIN DURING THE NIGHT ON
2/20-2/21. SNOW ARRIVED FROM THE SOUTH DURING THE EVENING ON 2/20...
BUT AS WARMER AIR MOVED NORTH TO THE EAST OF THE LOW TRACK TOWARD
WESTERN UPPER MICHIGAN...THE LIGHTER PRECIPITATION TO THE EAST OF A
LINE FROM CRYSTAL FALLS TO THE HURON MOUNTAINS BECAME MIXED WITH OR
CHANGED TO SLEET...FREEZING RAIN AND RAIN. MODERATE TO HEAVY SNOW
FELL OVER THE WEST THROUGH MUCH OF THE NIGHT. SOUTHEAST WINDS GUSTED
AS HIGH AS 40 TO 50 MPH AT MANY LOCATIONS DURING THE EVENING ON
2/20...WITH A PEAK WIND GUST TO 58 MPH AT MENOMINEE. ONCE THE LOW
SHIFTED INTO LAKE SUPERIOR IN THE MORNING ON 2/21...THE WIND SHIFTED
TO THE WEST AND ADVECTED COLDER AIR BACK OVER THE U.P. PERIODS OF
SNOW CONTINUED THROUGH MUCH OF THE DAY EXCEPT OVER THE SOUTH
CENTRAL...WHERE THERE WERE ONLY SCATTERED SNOW SHOWERS. STORM TOTAL
SNOW THROUGH THE DAY ON 2/21 RANGED FROM AS MUCH AS 12 TO 18 INCHES
OVER THE WEST FROM IRONWOOD TO THE KEWEENAW TO LESS THAN AN INCH
OVER THE SOUTH CENTRAL. THE WEST WINDS WERE PARTICULARLY GUSTY OVER
THE EXPOSED KEWEENAW PENINSULA...WHERE WIND GUSTS PEAKED AT 59 MPH
AT THE HOUGHTON COUNTY AIRPORT. THE EXTENSIVE BLOWING SNOW WHIPPED
UP BY THESE STRONG WINDS AND THE FALLING SNOW RESULTED IN WIDESPREAD
BLIZZARD CONDITIONS THAT CLOSED DOWN MANY SECONDARY ROADS ACROSS THE
KEWEENAW. AS THE DEEP LOW PRESSURE SYSTEM MOVED SLOWLY NORTH THROUGH
ONTARIO AND INTO HUDSON BAY BY 2/23...GENERALLY LIGHT SNOW SHOWERS
CONTINUED IN THE WEST WIND SNOW BELTS OVER THE KEWEENAW AND NEAR
LAKE SUPERIOR EAST OF PICTURED ROCKS NATIONAL LAKESHORE. BUT THE
PERSISTENT GUSTY WINDS THAT REACHED 50 TO 60 MPH CAUSED BLIZZARD
CONDITIONS TO PERSIST OVER THE KEWEENAW INTO 2/22. THE WEST WIND
GUSTS DIMINISHED TO 30 TO 40 MPH ON 2/23...BUT BLOWING SNOW AND
REDUCED VISIBILITIES CONTINUED TO PLAGUE THE KEWEENAW. ALTHOUGH SOME
LIGHT SNOW SHOWERS LINGERED INTO 2/24...THE APPROACH OF A HIGH
PRESSURE RIDGE FINALLY CAUSED THE LAKE EFFECT SNOW IN AREAS FAVORED
BY THE WEST TO NORTHWEST WINDS TO DIMINISH BY THE AFTERNOON ON 2/24.
ADDITIONAL SNOWFALL FROM 2/22 INTO 2/24 ADDED UP TO 4 TO 8 INCHES
OVER THE HIGHER TERRAIN FROM ONTONAGON THROUGH THE KEWEENAW...WITH
AS MUCH AS 9.0 ADDITIONAL INCHES AT PAINESDALE IN HOUGHTON COUNTY.
THE SNOW DEPTH AT THAT LOCATION REACHED 60 INCHES ON 2/24. ABOUT 2
TO 4 INCHES OF THE WHITE STUFF PILED UP NEAR LAKE SUPERIOR FROM
MUNISING EAST TO GRAND MARAIS AND WHITEFISH POINT. AREAS AWAY FROM
THESE SNOW BELTS WERE GENERALLY CLEAR TO PARTLY CLOUDY AND COLD WITH
NOTHING MORE THAN A FEW FLURRIES ON 2/22 THROUGH 2/24. MEAN DAILY
TEMPERATURES AROUND 5 DEGREES ABOVE NORMAL ON 2/21 FELL TO 5 TO 15
DEGREES BELOW AVERAGE ON 2/22 THROUGH 2/24.

A VERY COLD AIRMASS PREVAILED ACROSS THE UPPER GREAT LAKES ON 2/25
AND 2/26. ALTHOUGH SOME LAKE EFFECT SNOW SHOWERS FELL IN THE
NORTHWEST WIND SNOW BELTS DOWNWIND OF LAKE SUPERIOR...SNOW
ACCUMULATIONS WERE NO MORE THAN AN INCH OR TWO. WINDS GUSTING AS
HIGH AS 35 TO 40 MPH CAUSED SOME BLOWING SNOW MAINLY AT OPEN AREAS
NEAR LAKE SUPERIOR AND DROPPED WIND CHILLS DOWN TO 20 TO 30 BELOW
ZERO DURING THE OVERNIGHT ON 2/25-2/26 AND THE MORNING ON 2/26...
WHEN THE THERMOMETER DIPPED AS LOW AS -21 AT A LOCATION NEAR
NEWBERRY. MEAN DAILY TEMPERATURES ON 2/25 AND 2/26 AVERAGED 20
DEGREES BELOW NORMAL.

LIGHT SNOW THAT ARRIVED IN THE AFTERNOON ON 2/26 HERALDED THE
ARRIVAL OF A STRONG COLD FRONT THAT USHERED AN EVEN COLDER AIRMASS
INTO THE UPPER LAKES. SOUTHWEST WINDS GUSTING TO 30 TO 40 MPH IN THE
AFTERNOON ON 2/26 AHEAD OF THIS FRONT SHIFTED TO NORTHWEST DURING
THE NIGHT ON 2/26-2/27. THE WINDS BEHIND THIS FRONTAL PASSAGE GUSTED
AS HIGH AS 45 TO 55 MPH NEAR LAKE SUPERIOR AND UP TO 35 MPH OVER THE
INTERIOR. THESE STRONG WINDS CAUSED EXTENSIVE BLOWING SNOW AND NEAR
BLIZZARD CONDITIONS IN SOME AREAS...MAINLY NEAR THE BIG LAKE. M-28
BETWEEN HARVEY IN MARQUETTE COUNTY AND MUNISING WAS CLOSED INTO THE
AFTERNOON ON 2/27. WIND CHILLS FELL TO AS LOW AS -20 TO -40 TOWARD
DAWN ON 2/27. THE CORE OF THE TRAILING ARCTIC AIRMASS MOVED OVERHEAD
ON 2/27...RESULTING IN SOME DAILY RECORD LOW MAXIMUM TEMPERATURES
BELOW ZERO AT MANY LOCATIONS DESPITE PARTIAL SUNSHINE. A LOCATION
OVER THE HURON MOUNTAINS IN NORTHWEST MARQUETTE COUNTY REPORTED THE
LOWEST MAXIMUM OF -6. AT MOST OF THE LOCATIONS WITH A SUB-ZERO HIGH
TEMPERATURE... 2/27 IN 2014 GOES DOWN IN THE RECORD BOOKS AS THE
LATEST DAY IN THE SEASON WITH SUCH SIGNIFICANT COLD. AS ARCTIC HIGH
PRESSURE PASSED OVERHEAD DURING THE NIGHT ON 2/27-2/28 AND WINDS
BECAME LIGHT...THE MERCURY PLUMMETED TO DAILY RECORD LEVELS WELL
BELOW ZERO AT MOST PLACES...REACHING 30 BELOW ZERO OR LOWER AT THE
COLDEST SPOTS. A LOCATION NEAR NEWBERRY REPORTED THE LOWEST
TEMPERATURE OF THE NIGHT AND THE WINTER AS WELL WITH A -41 READING
AT DAWN ON 2/28. DESPITE SOME INCREASE IN HIGH CLOUDS ON 2/28 AHEAD
OF LOW PRESSURE MOVING EAST THROUGH MINNESOTA...TEMPERATURES DURING
THE AFTERNOON REBOUNDED ABOVE ZERO EVERYWHERE. MEAN DAILY
TEMPERATURES ON 2/27 AND 2/28 ENDED UP AROUND A FRIGID 30 DEGREES
BELOW NORMAL. THE LOW MOVING EAST FROM MINNESOTA THROUGH WISCONSIN
AND LOWER MICHIGAN DROPPED 2 TO 6 INCHES OF SNOW ACROSS MOST OF THE
SOUTHEAST HALF OF UPPER MICHIGAN DURING THE LATE AFTERNOON AND
EVENING ON 2/28...AND AS MUCH AS 6.5 INCHES AT COOKS IN SCHOOLCRAFT
COUNTY. GENERALLY AN INCH OR LESS FELL OVER THE NORTHWEST HALF
FARTHER FROM THE LOW TRACK.

                           MARCH FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING A GREATER THAN
CLIMATOLOGICAL CHANCE OF A BELOW NORMAL MONTHLY MEAN TEMPERATURE BUT
AN EQUAL CHANCE OF ABOVE AND BELOW NORMAL MONTHLY PRECIPITATION OVER
ALL OF UPPER MICHIGAN IN MARCH 2014.

                         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 3/9 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 12:57
PM 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 INCHES 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 (1984 FEATURED A VERY COLD MARCH WITH
TEMPERATURES AVERAGING OVER 6 DEGREES BELOW NORMAL)...THE LOW
TEMPERATURE AT IRONWOOD PLUMMETED TO 34 BELOW ZERO. MARCH 2002
TEMPERATURES AVERAGED 5 TO 8 DEGREES BELOW NORMAL. IRONWOOD OBSERVED
THE SECOND COLDEST MARCH ON RECORD SINCE 1901...AND THE MARQUETTE
NWS SAW ITS THIRD COLDEST MARCH. 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. THE -30 DEGREE LOW AT THE
MARQUETTE NWS ON THE SAME MORNING SMASHED NOT ONLY THE DAILY LOW
TEMPERATURE RECORD FOR 3/3 BUT ALSO THE ALL TIME LOW MARCH
TEMPERATURE EVER OBSERVED AT THAT SITE (-27 ON 3/1/1962). THIS COLD
WAVE HELPED DROP THE MARCH 2003 MONTHLY TEMPERATURE 2 TO 6 DEGREES
BELOW THE AVERAGE.

ALTHOUGH LAKE EFFECT SNOW BECOMES LESS LIKELY DURING MARCH AS LAKE
SUPERIOR TEMPERATURES USUALLY REACH THEIR LOWEST READINGS...AVERAGE
PRECIPITATION DURING MARCH IS MORE THAN DURING FEBRUARY BECAUSE THE
NORTHWARD MOVING JET STREAM BRINGS MORE STORMS 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.
