...LEVELS NEAR RECORD LOWS ON LAKES MICHIGAN-HURON IN FEBRUARY...
INCREASED EVAPORATION DUE TO VERY WARM LAKE WATERS AND A LACK OF
SIGNIFICANT WINTER ICE HAS RESULTED IN WELL BELOW NORMAL GREAT LAKES
WATER LEVELS FOR THE PAST SEVERAL YEARS. IN COMBINATION WITH DROUGHT
THAT PLAGUED THE LOWER LAKES THROUGH MUCH OF 2012...THE WATER LEVEL
ON LAKES MICHIGAN-HURON DROPPED TO JUST BELOW THE RECORD LOW IN
NOVEMBER THROUGH JANUARY. INCREASED PRECIPITATION IN LATE JANUARY
THROUGH FEBRUARY HELPED RAISE WATER LEVELS TO A FEW INCHES ABOVE THE
RECORD LOW IN FEBRUARY. BUT LEVELS ON LAKES MICHIGAN-HURON WERE
STILL ALMOST 27 INCHES BELOW THE LONG TERM AVERAGE AT THE END OF THE
MONTH. AS IS TYPICAL IN FEBRUARY...LAKE SUPERIOR WATER LEVELS FELL
SLOWLY...HOLDING A BIT MORE THAN A FOOT BELOW NORMAL THROUGH 2/28.
PERIODS OF INTENSE COLD DURING THE SECOND HALF OF JANUARY AND MAINLY
THE FIRST HALF OF FEBRUARY MAINTAINED SIGNIFICANT ICE COVER ON THE
BAY OF GREEN BAY THROUGH FEBRUARY. ICE FORMATION ON LAKE SUPERIOR
WAS LIMITED TO MAINLY THE NEARSHORE AREAS AND IN THE MORE SHELTERED
BAYS.

GREATEST SNOW DEPTH...48 INCHES AT HERMAN IN BARAGA COUNTY ON 2/20
FEBRUARY 2013 FEATURED A FAIRLY ACTIVE...CHANGEABLE WEATHER PATTERN
THAT ALLOWED SOME DEEPER...MOISTURE-LADEN LOW PRESSURE SYSTEMS TO
IMPACT UPPER MICHIGAN FROM TIME-TO-TIME. IN COMBINATION WITH LOCALLY
HEAVY LAKE EFFECT SNOWS THAT FELL WHEN A DEEP UPPER TROUGH DOMINATED
DURING THE FIRST AND PART OF THE THIRD WEEKS...MONTHLY PRECIPITATION
AND SNOWFALL WERE ABOVE NORMAL TO WELL ABOVE AVERAGE...ESPECIALLY
OVER THE EAST AND KEWEENAW. FEBRUARY PRECIPITATION AND SNOWFALL
REACHED OVER 4.00 INCHES AND 50 TO EVEN 60 INCHES RESPECTIVELY AT
SOME LOCATIONS IN THESE AREAS...VALUES AS MUCH AS 200 TO 300 PERCENT
OF NORMAL. IN FACT...SOME PLACES OVER THE KEWEENAW AND IN THE AREA
EAST OF A LINE FROM MARQUETTE TO MENOMINEE ENDURED A TOP FIVE
WETTEST AND SNOWIEST FEBRUARY. AS IS OFTEN THE CASE IN DEEP
WINTER...THE LEAST SNOW AND PRECIPITATION FELL OVER THE INTERIOR
WEST HALF...WHERE TOTALS ENDED UP 14 TO 18 INCHES AND 1.00 TO 1.50
INCHES. THESE NUMBERS ARE ABOUT 150 TO 175 PERCENT OF NORMAL.
THE MOST NOTABLE STORM OF THE MONTH OCCURRED FROM LATE ON 2/18
THROUGH 2/20...WHEN A LOW PRESSURE SYSTEM MOVING THROUGH THE CENTRAL
GREAT LAKES AND INTO ONTARIO BROUGHT SOME HEAVY SNOW TO MAINLY NORTH
CENTRAL AND EASTERN UPPER MICHIGAN THROUGH 2/19. EVEN AFTER THE LOW
MOVED INTO ONTARIO...LAKE EFFECT SNOW CONTINUED NEAR LAKE SUPERIOR
THROUGH MOST OF 2/20. NORTH TO NORTHWEST WINDS GUSTING AS HIGH AS 50
MPH CAUSED EXTENSIVE BLOWING SNOW AND BLIZZARD CONDITIONS AT TIMES.
CONDITIONS WERE SO BAD BETWEEN MARQUETTE AND MUNISING THE STATE
POLICE CLOSED HIGHWAY M-28 FROM THE AFTERNOON ON 2/19 THROUGH THE
EARLY MORNING OF 2/21. BY THE TIME THE SNOW ENDED LATE ON 2/20...AS
MUCH AS 18 TO 30 INCHES OF SNOW HAD FALLEN OVER PORTIONS OF
MARQUETTE AND ALGER COUNTIES. SHINGLETON IN ALGER COUNTY REPORTED
THE HIGHEST TOTAL OF 30 INCHES ALONG WITH 6 TO 8 FOOT DRIFTS BUILT
UP BY THE BLOWING SNOW AND STRONG WINDS. ALTHOUGH MOST PLACES NEAR
LAKE SUPERIOR AND OVER THE EAST HAD AT LEAST A FOOT OF SNOW...ONLY
AROUND 2 INCHES OF THE WHITE STUFF ACCUMULATED DURING THE ENTIRE
EVENT OVER THE SOUTH FROM MENOMINEE TO IRON MOUNTAIN...CRYSTAL FALLS
AND IRON RIVER.
ALTHOUGH THERE WERE SOME MILD STRETCHES IN FEBRUARY DURING THE
SECOND AND FOURTH WEEKS...INTENSE COLD DURING THE FIRST 6 DAYS AND
JUST AFTER MID-MONTH WHEN THE DEEP UPPER TROUGH DOMINATED THE GREAT
LAKES LOWERED THE MONTHLY MEAN TEMPERATURE IN FEBRUARY 2013 TO AS
MUCH AS 3 DEGREES BELOW NORMAL NEAR THE WISCONSIN BORDER TO ABOUT
0.5 DEGREE BELOW AVERAGE OVER THE NORTH CENTRAL NEAR LAKE SUPERIOR
AND EAST. THE MEAN MONTHLY TEMPERATURE...WHICH RANGED BETWEEN ABOUT
10 DEGREES AT SOME OF THE COLDER PLACES OVER THE INTERIOR AND 20
DEGREES NEAR THE WARMING INFLUENCE OF THE LAKES...WAS ABOUT 1 TO 3
DEGREES LOWER THAN THE MEAN MONTHLY TEMPERATURES LOGGED IN JANUARY
ACROSS UPPER MICHIGAN.
WHEN ARCTIC AIRMASSES DOMINATED...THE MERCURY SANK INTO THE TEENS
BELOW ZERO AT AT LEAST ONE SPOT EACH MORNING FROM 2/1 THROUGH
2/6...ON 2/9...2/16...2/17 AND 2/21. SOME MINIMUM READINGS WERE INTO
THE -20S ON 2/2...2/4...2/9 AND 2/17...INCLUDING THE MONTHLY LOW OF
-28 AT CLARKSBURG-CHAMPION ON 2/4 AND STAMBAUGH ON 2/17. WHEN THE
TROUGH WEAKENED AND GAVE WAY TO UPPER RIDGING IN THE GREAT LAKES AT
A TIME OF INCREASING SUN ANGLE AND LENGTH OF DAYLIGHT...SOME
LOCATIONS REPORTED MAXIMUM TEMPERATURES IN THE 40S ON 2/11...
2/13...2/18...2/25 AND 2/26.
---------------------------------------------------------------------
...WINTER 2012-2013 SUMMARY...
THE WINTER OF 2012-2013 WAS ACTUALLY A TALE OF TWO SEASONS. THE
FIRST HALF OF THE WINTER FROM 12/1 THROUGH 1/15 WAS QUITE MILD WITH
BELOW NORMAL PRECIPITATION AND SNOWFALL AS A FLOW OF PACIFIC AIR
DOMINATED. THE UPPER AIR PATTERN SHIFTED IN MID-JANUARY...FREQUENTLY
FEATURING AN UPPER TROUGH OVER THE EAST AND CENTRAL NORTH AMERICA
THROUGH FEBRUARY. THE RESULT WAS A PERIOD OF BELOW NORMAL
TEMPERATURES. THERE WAS ALSO ABOVE NORMAL PRECIPITATION AND SNOWFALL
OVER UPPER MICHIGAN DURING THE SECOND HALF OF THE WINTER WITH THE
FREQUENT PASSAGE OF LOW PRESSURE SYSTEMS...ESPECIALLY OVER THE EAST
HALF. SINCE THE FIRST HALF OF THE WINTER WAS WARMER THAN THE SECOND
HALF WAS COLDEST...THE OVERALL MEAN TEMPERATURE ENDED UP FROM 1.5 TO
3.0 DEGREES ABOVE NORMAL.

FEBRUARY WEATHER SUMMARY
A DEEP UPPER TROUGH OVER CENTRAL AND EASTERN NORTH AMERICA FUNNELED
BITTERLY COLD ARCTIC AIR INTO THE GREAT LAKES DURING THE FIRST SIX
DAYS OF FEBRUARY. MINIMUM TEMPERATURES ON EACH DAY FROM 2/1 THROUGH
2/6 SANK AS LOW AS THE TEENS BELOW ZERO AT AT LEAST A COUPLE OF THE
INTERIOR COLD SPOTS AND AS LOW AS -23 AT STAMBAUGH IN IRON COUNTY ON
2/2 AND THE MONTHLY LOW OF -28 AT CLARKSBURG-CHAMPION IN MARQUETTE
COUNTY ON 2/4. THE THERMOMETER FAILED TO RISE ABOVE 10 ABOVE AT MANY
LOCATIONS IN THE AFTERNOONS ON 2/1 THROUGH 2/3 AND NEVER BROKE THE
ZERO MARK AT IRONWOOD ON 2/1. WIND CHILLS DIPPED AS LOW AS -25 TO
-35. AS A RESULT...MEAN DAILY TEMPERATURES ON 2/1 THROUGH 2/6
AVERAGED 10 TO AS MUCH AS 20 DEGREES BELOW NORMAL. LAKE EFFECT SNOW
SHOWERS WERE ALSO COMMON DURING THIS PERIOD AS THE VERY COLD AIR
POURED ACROSS THE RELATIVELY WARM WATERS OF LAKE SUPERIOR...
ESPECIALLY WHEN DISTURBANCES CROSSED THE UPPER LAKES ON 2/1 INTO
2/2...2/3 INTO 2/4...AND ON 2/5. IN AREAS FAVORED BY NORTHWEST
WINDS...TOTAL LAKE EFFECT SNOW ACCUMULATIONS DURING THESE SIX DAYS
RANGED FROM 15 TO 20 INCHES ON THESE SIX DAYS...WITH AS MUCH AS 19.8
INCHES FALLING AT MOHAWK IN KEWEENAW COUNTY ON 2/1 INTO 2/6. ONLY
LIGHT SNOW SHOWERS FELL ACROSS AREAS WELL INLAND FROM LAKE SUPERIOR.
DURING THE SECOND WEEK OF FEBRUARY...THE UPPER TROUGH RETREATED TO
THE NORTH AND ALLOWED A MORE WEST-TO-EAST FLOW TO DOMINATE THE
UNITED STATES. TWO LARGER SCALE LOW PRESSURE SYSTEMS EMBEDDED IN
THIS MORE ACTIVE REGIME IMPACTED UPPER MICHIGAN DURING THIS TIME.
THE FIRST OF THESE MOVED THROUGH THE LOWER GREAT LAKES ON 2/7 AND
DROPPED 2 TO 4 INCHES OF SNOW ON THE U.P. MEAN DAILY TEMPERATURES ON
2/7 ROSE TO ABOUT 5 DEGREES ABOVE NORMAL BEFORE DROPPING TO AROUND 5
DEGREES BELOW AVERAGE ON 2/8 AND 2/9 AS COLDER AIR FOLLOWED THE
DEPARTING LOW INTO THE UPPER GREAT LAKES. NO MORE THAN A FEW INCHES
OF LAKE EFFECT SNOW FELL DURING THIS COLD AIR INCURSION. AS HIGH
PRESSURE MOVED THROUGH THE UPPER LAKES ON 2/8 INTO 2/9 AND SKIES
CLEARED BRIEFLY...THE MERCURY FELL OFF WELL BELOW ZERO IN THE EARLY
MORNING ON 2/9. MINIMUM READINGS WERE AS LOW AS -21 AT ONE OF THE
COLDER LOCATIONS NEAR NEWBERRY.
A MORE SIGNIFICANT LOW PRESSURE SYSTEM TOOK AIM ON THE UPPER GREAT
LAKES ON 2/10 INTO 2/12. SINCE THIS DISTURBANCE MOVED RIGHT ACROSS
UPPER MICHIGAN ON 2/11...THE ASSOCIATED PRECIPITATION WAS A WINTRY
MIX OF SNOW...SLEET...FREEZING RAIN AND RAIN LATE ON 2/10 THROUGH
THE MORNING ON 2/11. THE RETURN OF COLD AIR FOLLOWING ITS PASSAGE
INTO SOUTHEAST ONTARIO ON 2/11 CHANGED THE MIXED BAG TO LAKE EFFECT
SNOW THAT LINGERED INTO 2/12. THE HEAVIEST SNOW UP TO 6 TO 10 INCHES
DURING THIS EVENT FELL OVER THE NORTHWEST HALF OF UPPER MICHIGAN
BECAUSE MORE OF THE PRECIPITATION WAS IN THE FORM OF SNOW ON THE COLD
SIDE OF THE LOW TRACK AND HEAVIER LAKE EFFECT SNOW IMPACTED THIS
AREA. MOHAWK LED REPORTING SITES WITH 10.5 INCHES OF THE WHITE STUFF
AND 1.24 INCHES OF WATER EQUIVALENT PRECIPITATION. ALTHOUGH
PRECIPITATION AMOUNTS OVER THE EAST AND SOUTH CENTRAL WERE GENERALLY
0.75 TO 1.00 INCH AND UP TO 1.07 INCHES AT MENOMINEE...ANY SNOW IN
THIS AREA WAS NO MORE THAN AN INCH OR TWO BECAUSE TEMPERATURES THAT
ROSE WELL INTO THE 30S AND AS HIGH AS 41 AT MENOMINEE EARLY ON 2/11
CAUSED THE BULK OF THE PRECIPITATION TO BE IN THE FORM OF RAIN. A
RIDGE OF HIGH PRESSURE AND SOME PACIFIC AIR FOLLOWED THE LOW ACROSS
THE UPPER GREAT LAKES ON 2/13. THE COMBINATION OF THIS WARMER
AIRMASS AND A MOSTLY SUNNY SKY BOOSTED THE MERCURY OVER 40 AT MANY
LOCATIONS AND ALL THE WAY TO THE MONTHLY HIGH OF 44 AT KENTON IN FAR
SOUTHERN HOUGHTON COUNTY. WITH THE ARCTIC AIR BOTTLED UP IN
CANADA...MEAN DAILY TEMPERATURES ON 2/10 THROUGH 2/13 ENDED UP 5 TO
15 DEGREES ABOVE AVERAGE.
THE RESPITE FROM THE COLD FOR UPPER MICHIGAN WAS BRIEF. A LOW
PRESSURE SYSTEM MOVING THROUGH THE GREAT LAKES ON VALENTINE`S DAY
HERALDED THE DEEPENING OF ANOTHER UPPER TROUGH IN CENTRAL AND
EASTERN NORTH AMERICA THAT ALLOWED MORE COLD AIR TO POUR INTO THE
AREA ON 2/15 THROUGH 2/17. THIS LOW PRESSURE DISTURBANCE BROUGHT
SOME MODERATE SNOW TO MAINLY THE SOUTH CENTRAL AND EAST...DROPPING
UP TO 5 INCHES OF THE WHITE STUFF ON COOKS IN SCHOOLCRAFT COUNTY ON
2/14. AS COLDER AIR FOLLOWED THE STORM SYSTEM INTO THE UPPER LAKES
LATER ON 2/14...THE PRECIPITATION TRANSITIONED TO LAKE EFFECT SNOW
SHOWERS... HEAVIEST IN THE NORTHWEST WIND SNOW BELTS. SNOW TOTALS
FROM 2/14 THROUGH 2/17 REACHED 8 INCHES OR MORE AT SEVERAL
LOCATIONS... INCLUDING 9.0 INCHES AT GRAND MARAIS IN ALGER COUNTY
AND 8.2 INCHES AT IRONWOOD. THE ARRIVAL OF AN ARCTIC HIGH PRESSURE
RIDGE LATE ON 2/16 INTO 2/17 ENDED THIS ROUND OF SNOW SHOWERS. BUT
AS SKIES TURNED MOSTLY CLEAR OVER THE WEST HALF DURING THE NIGHT ON
2/16-2/17 WITH THE INFLUX OF DRIER AIR...TEMPERATURES PLUMMETED
UNDER 20 BELOW AT SOME OF THE COLDER INTERIOR LOCATIONS AND ALL THE
WAY TO -28 AT STAMBAUGH. MEAN DAILY TEMPERATURES AROUND 5 DEGREES
ABOVE NORMAL ON 2/14 FELL OFF TO 5 TO 10 DEGREES BELOW AVERAGE ON
2/15 THROUGH 2/17.
ALTHOUGH A SOUTHERLY FLOW ON THE WESTERN FLANK OF THE HIGH PRESSURE
RIDGE RESPONSIBLE FOR THE EARLY 2/17 CHILL BROUGHT A RETURN OF
WARMER AIR AND MEAN DAILY TEMPERATURES 5 TO 10 DEGREES ABOVE NORMAL
ON 2/18...A DEVELOPING LOW PRESSURE SYSTEM TAKING SHAPE IN THE
PLAINS AND MOVING TOWARD THE GREAT LAKES WOULD BRING THE MOST
SIGNIFICANT WINTER WEATHER EVENT OF THE MONTH TO UPPER MICHIGAN. AS
THIS LOW TRACKED THROUGH THE CENTRAL GREAT LAKES AND INTO ONTARIO...
SOME HEAVY SNOW FELL MAINLY OVER NORTH CENTRAL AND EASTERN UPPER
MICHIGAN THROUGH 2/19. EVEN AFTER THE LOW MOVED INTO ONTARIO...LAKE
EFFECT SNOW CONTINUED NEAR LAKE SUPERIOR THROUGH MOST OF 2/20. NORTH
TO NORTHWEST WINDS GUSTING AS HIGH AS 50 MPH CAUSED EXTENSIVE
BLOWING SNOW AND BLIZZARD CONDITIONS AT TIMES. CONDITIONS WERE SO
BAD BETWEEN MARQUETTE AND MUNISING THE STATE POLICE CLOSED HIGHWAY
M-28 FROM THE AFTERNOON ON 2/19 THROUGH THE EARLY MORNING OF 2/21.
BY THE TIME THE SNOW ENDED LATE ON 2/20...AS MUCH AS 18 TO 30 INCHES
OF SNOW HAD FALLEN OVER PORTIONS OF MARQUETTE AND ALGER COUNTIES.
SHINGLETON IN ALGER COUNTY REPORTED THE HIGHEST TOTAL OF 30 INCHES
ALONG WITH 6 TO 8 FOOT DRIFTS BUILT UP BY THE BLOWING SNOW AND
STRONG WINDS. ALTHOUGH MOST PLACES NEAR LAKE SUPERIOR AND OVER THE
EAST HAD AT LEAST A FOOT OF SNOW...ONLY AROUND 2 INCHES OF THE WHITE
STUFF ACCUMULATED DURING THE ENTIRE EVENT OVER THE SOUTH FROM
MENOMINEE TO IRON MOUNTAIN...CRYSTAL FALLS AND IRON RIVER. NEAR
NORMAL MEAN DAILY TEMPERATURES ON 2/19 FELL OFF TO 5 TO 10 DEGREES
BELOW AVERAGE ON 2/20.
TRANQUIL WEATHER AND NEAR NORMAL TEMPERATURES PREVAILED ON 2/21 OVER
THE UPPER GREAT LAKES AS HIGH PRESSURE BUILT THROUGH ONTARIO. A LOW
PRESSURE SYSTEM TRACKING THROUGH THE CENTRAL GREAT LAKES BROUGHT
ANOTHER ROUND OF SNOW TO THE U.P. ON 2/22 THROUGH 2/23. BY THE TIME
LINGERING LAKE EFFECT SNOW IN ITS WAKE ENDED EARLY ON 2/24...MOST
PLACES HAD PICKED UP 3 TO 6 INCHES. NEGAUNEE IN MARQUETTE COUNTY LED
REPORTING STATIONS WITH A TOTAL OF 7.1 INCHES OF SNOW. MEAN DAILY
TEMPERATURES ON 2/22 THROUGH 2/24 AVERAGED ABOUT 5 DEGREES ABOVE
NORMAL.
AFTER A PERIOD OF QUITE WEATHER DOMINATED BY HIGH PRESSURE FROM THE
AFTERNOON ON 2/24 THROUGH 2/26...YET ANOTHER LOW PRESSURE SYSTEM
TRACKED THROUGH THE LOWER GREAT LAKES ON 2/27....DROPPING 2 TO 5
INCHES OF NEW SNOW TO MUCH OF THE EAST HALF OF UPPER MICHIGAN ON
2/27 INTO 2/28. AS WAS THE CASE A COUPLE DAYS EARLIER...NEGAUNEE IN
THE HIGHER TERRAIN OF MARQUETTE COUNTY SAW THE MOST SNOW WITH 6.0
INCHES. GUSTY NORTHEAST WINDS TO 30 TO 35 MPH NEAR LAKE SUPERIOR
CAUSED SOME BLOWING SNOW AS WELL. ANY SNOW OVER THE WEST WAS LESS
THAN AN INCH. MEAN DAILY TEMPERATURES ON 2/25 THROUGH 2/28 AVERAGED
FROM NEAR NORMAL TO AS MUCH AS 10 DEGREES ABOVE THE MEAN ON 2/27.
APRIL FORECAST
THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING A GREATER THAN
CLIMATOLOGICAL CHANCE OF AN ABOVE NORMAL MONTHLY MEAN TEMPERATURE
OVER CENTRAL AND EASTERN UPPER MICHIGAN BUT AN EQUAL CHANCE OF AN
ABOVE AND BELOW NORMAL MEAN TEMPERATURE OVER THE WEST IN APRIL 2013.
THE CPC INDICATES A GREATER THAN CLIMATOLOGICAL CHANCE OF ABOVE
NORMAL PRECIPITATION OVER ALL OF UPPER MICHIGAN IN APRIL.
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. RECORD HIGH MONTHLY 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. APRIL 2008 AND 2009
ALSO FEATURED HEAVY SNOW IN MANY LOCATIONS WITH SOME TOP 10 MONTHLY
SNOW AMOUNTS. IN FACT...APRIL 2008 GOES DOWN IN THE RECORD BOOKS AT
IRON MOUNTAIN AS THE SNOWIEST FOURTH MONTH ON RECORD WITH 19.5
INCHES OF THE WHITE STUFF. THE MERCURY HAS FALLEN AS LOW AS -12 AT
IRONWOOD (4/7/82)...-9 AT THE MARQUETTE NWS (4/6/2003)...-7 AT
MANISTIQUE (4/5/72)...-6 AT IRON MOUNTAIN (4/5/72)...-4 AT MUNISING
(4/6/50)... -2 AT NEWBERRY (4/1/23) AND ZERO AT HOUGHTON (4/4/54)
AND ONTONAGON (4/7/96). IRONWOOD HAS REPORTED TEMPERATURES WELL
BELOW ZERO EVEN AFTER MID MONTH...-8 AND -5 ON 4/17/83 AND 4/18/83
RESPECTIVELY. APRIL 1995 AND 1996 WERE NOTORIOUSLY COLD ACROSS UPPER
MICHIGAN WITH TEMPERATURES AVERAGING FIVE DEGREES OR MORE BELOW
NORMAL...AND MANY PLACES COUNT THESE MONTHS IN THE TOP FIVE COLDEST
APRILS ON RECORD. APRIL 1950 STANDS OUT AS VERY CHILLY AT STATIONS
WITH A LONGER CLIMATE RECORD. THAT MONTH IS THE COLDEST APRIL AT
NEWBERRY (AVERAGE TEMPERATURE OF 29.9)...IRON MOUNTAIN (32.3) AND
MUNISING (31.3) AND IN THE TOP FIVE COLDEST AT IRONWOOD (31.0) AND
MANISTIQUE (33.0).
