...WEST AND CENTRAL UPPER MICHIGAN CLIMATE SUMMARY FOR 2012...

 

...TOP FIVE WARMEST YEAR AT MOST PLACES WITH UNPRECEDENTED WARMTH

IN MARCH...

...GENERALLY DRY WITH BELOW NORMAL CALENDAR YEAR SNOWFALL...

...RECORD LOW WATER LEVELS REACHED ON LAKES MICHIGAN/HURON...

 

DESPITE SOME CHILL FROM LATE SUMMER INTO THE FALL...THE MEAN ANNUAL

TEMPERATURE IN 2012 ENDED UP 3 TO 4 DEGREES ABOVE THE 30-YEAR

NORMAL...ENOUGH TO QUALIFY 2012 AS ONE OF THE TOP FIVE WARMEST YEARS

ON RECORD AT MOST LOCATIONS. IN FACT...THE YEAR WAS THE WARMEST ON

RECORD OVER THE NORTH CENTRAL FROM MUNISING TO MARQUETTE...WHERE

RECORDS DATE BACK INTO THE 1870S. THE WARMTH WAS MOST PRONOUNCED IN

MARCH...WHEN THE MEAN MONTHLY TEMPERATURE RAN 10 TO 16 DEGREES ABOVE

AVERAGE. AT MOST SPOTS...2012 ENDED UP 2 TO 3 DEGREES WARMER THAN

2011.

 

OVERALL...2012 WAS DRIER THAN NORMAL AT MOST PLACES...MAINLY ACROSS

THE WEST AND ESPECIALLY THE SOUTH CENTRAL NEAR THE WISCONSIN BORDER.

AT IRON MOUNTAIN...2012 GOES DOWN IN THE RECORD BOOKS AS THE 10TH

DRIEST YEAR ON RECORD WITH THE OBSERVED PRECIPITATION OF 23.72

INCHES EXACTLY 6 INCHES BELOW NORMAL...OR ABOUT 80 PERCENT OF THAT

AVERAGE. IRON MOUNTAIN TENDED TO MISS OUT ON MANY OF THE HEAVIER

PRECIPITATION EPISODES THAT OCCURRED DURING MORE ACTIVE WEATHER

PERIODS IN JANUARY...LATE FEBRUARY INTO EARLY MARCH...AND OVER THE

SUMMER. DESPITE THE OVERALL DRYNESS...2012 WAS WETTER THAN AN EVEN

DRIER 2011 AT MOST LOCATIONS.

 

WITH SUCH WARM WEATHER MUCH OF THE TIME DURING THE COLDER MONTHS...

CALENDAR YEAR 2012 SNOWFALL WAS BELOW NORMAL TO WELL BELOW THE MEAN 

OVER MUCH OF UPPER MICHIGAN. THE DEPARTURES FROM NORMAL WERE MOST

SIGNIFICANT IN AREAS NEAR LAKE SUPERIOR THAT NORMALLY PICK UP A LOT

OF LAKE EFFECT SNOW BECAUSE THE WARMTH LIMITED THE OCCURRENCE OF THE

USUALLY QUITE PERSISTENT SNOW SHOWERS. SNOWFALL AT HOUGHTON IN 2012

WAS 136.3 INCHES...71.4 INCHES BELOW NORMAL. ONLY 55.7 INCHES OF THE

WHITE STUFF FELL IN THE CITY OF MARQUETTE IN ALL OF 2012...LESS THAN

50 PERCENT OF NORMAL AND THE THIRD LOWEST CALENDAR YEAR TOTAL SINCE

1885. THE 127.0 INCHES THAT ACCUMULATED NEAR ONTONAGON IS OVER 60

INCHES BELOW THE 30-YEAR AVERAGE AND THE FIFTH LOWEST ANNUAL TOTAL

THERE SINCE 1977.

____________________________________________________________________

                    ...SOME 2012 SUPERLATIVES...

 

HIGHEST CALENDAR YEAR SNOWFALL...196.3 INCHES AT HERMAN IN BARAGA

                                  COUNTY

 

GREATEST SNOW DEPTH...47 INCHES AT NEGAUNEE IN MARQUETTE COUNTY ON 3/4

 

LOWEST SNOWFALL...31.2 INCHES AT MENOMINEE

 

HIGHEST PRECIPITATION...38.07 INCHES AT ATLANTIC MINE IN HOUGHTON

                         COUNTY

 

LOWEST PRECIPITATION...23.11 INCHES AT NORWAY IN DICKINSON COUNTY

 

HIGHEST TEMPERATURE...95 AT LA BRANCHE IN MENOMINEE COUNTY AND IRON

                       MOUNTAIN ON 7/5...THEN AGAIN AT BARAGA...

                       MENOMINEE AND IRON MOUNTAIN ON 7/16...AND

                       FINALLY AT GARDEN CORNERS IN DELTA COUNTY ON

LOWEST TEMPERATURE...-26 AT WAKEFIELD IN GOGEBIC COUNTY ON 1/21

____________________________________________________________________

...GENERAL 2012 OVERVIEW...

 

THE WEATHER IN JANUARY AND FEBRUARY 2012 WAS DOMINATED BY A WEST-TO-

EAST FLOW OF RELATIVELY MILD PACIFIC AIR THAT BOOSTED MEAN MONTHLY

TEMPERATURES TO 4 TO 8 DEGREES ABOVE NORMAL AND PLACED BOTH MONTHS

INTO THE LIST OF TOP 10 WARMEST AT MOST LOCATIONS. MANY SPOTS SAW NO

SUB-ZERO TEMPERATURES AT ALL IN FEBRUARY...A MONTH THAT USUALLY

FEATURES QUITE A BIT OF THIS CHILL. ALTHOUGH THIS ANOMALOUS WARMTH

LIMITED LAKE EFFECT SNOWFALL...THE ACTIVE NATURE OF THE UPPER FLOW

IN JANUARY RESULTED IN ABOVE NORMAL PRECIPITATION AND NEAR NORMAL

SNOWFALL AT MOST PLACES EXCEPT THE SOUTH CENTRAL...WHICH TENDED TO

GET JUST GLANCED BY THE LOW PRESSURE SYSTEMS. WITH THE WARMTH AND

LACK OF SNOW...THE GROUND WAS BARE OF SNOW AT TIMES IN JANUARY AT

SOME PLACES OVER THE SOUTH CENTRAL U.P.

 

ALTHOUGH THE WEATHER PATTERN TURNED DRIER MOST OF FEBRUARY...A MORE

ACTIVE REGIME RETURNED LATE IN FEBRUARY INTO EARLY MARCH. A SERIES

OF STRONGER LOW PRESSURE SYSTEMS IMPACTED THE AREA THE LAST WEEK OF

FEBRUARY INTO EARLY MARCH...BRINGING SOME HEAVY PRECIPITATION AND

SNOWFALL THAT LIFTED FEBRUARY PRECIPITATION AND SNOWFALL TO NOT FAR

FROM NORMAL. THE FIRST OF THESE LOWS DROPPED AS MUCH AS 12 INCHES OF

SNOW AT MOHAWK IN KEWEENAW COUNTY ON 2/26 INTO 2/27. A STORM ON LEAP

DAY BURIED IRON RIVER AND STAMBAUGH IN IRON COUNTY UNDER 19 INCHES

OF SNOW. WINDS GUSTING UP TO 45 MPH DURING THE HEIGHT OF THIS 2/29

STORM CAUSED EXTENSIVE BLOWING SNOW WITH NEAR BLIZZARD CONDITIONS...

MAINLY IN OPEN AREAS NEAR THE GREAT LAKES. ANOTHER DEEP LOW PRESSURE

SYSTEM TRACKING THROUGH THE GREAT LAKES DUMPED AS MUCH AS 27 INCHES

OF SNOW ON ISHPEMING IN MARQUETTE COUNTY ON 3/2 INTO 3/4.

 

EVEN THOUGH MARCH CAME IN LIKE A LION...AN ANOMALOUSLY STRONG UPPER

RIDGE THAT DOMINATED FROM 3/7 UNTIL THE LAST WEEK BROUGHT

UNPRECEDENTED...RECORD WARMTH TO UPPER MICHIGAN. EVEN THOUGH THERE

WAS A RETURN OF SOME CHILLY WEATHER THE LAST WEEK...MONTHLY MEAN

TEMPERATURES WERE 10 TO 16 DEGREES ABOVE NORMAL...PLACING MARCH 

2012 AS THE WARMEST THIRD MONTH ON RECORD ALMOST EVERYWHERE. THE

MEAN MARCH TEMPERATURES WERE SO HIGH THESE VALUES WOULD HAVE BEEN

ABOVE NORMAL FOR APRIL. ON THE WARMEST DAYS FROM 3/17 THRU 3/21...

MEAN DAILY TEMPERATURES RAN AN INCREDIBLE 35 TO 40 DEGREES ABOVE

NORMAL. THERE WERE MANY NEW MONTHLY RECORD HIGH MAXIMUM AND MINIMUM

TEMPERATURES...INCLUDING HIGH TEMPERATURES OF 80 OR BETTER AND LOW

TEMPS OVER 50 AND EVEN 60 FOR THE FIRST TIME ON RECORD IN MARCH. IN

FACT...THESE DAYS WOULD HAVE BEEN SEASONABLY WARM FOR MID SUMMER.

DESPITE THE HEAVY SNOW EARLY IN MARCH...THE DOMINATING UPPER RIDGE

CAUSED MONTHLY WATER EQUIVALENT PRECIPITATION AND SNOW TO RUN BELOW

NORMAL AT ALL LOCATIONS. THE ANOMALIES WERE MOST PRONOUNCED OVER THE

WEST...WHICH MISSED OUT FOR THE MOST PART ON THE EARLY MONTH STORM.

 

EVEN THOUGH A DEEPENING UPPER TROUGH THE LAST HALF OF APRIL ALLOWED

FOR FREQUENT INCURSIONS OF COLDER CANADIAN AIR...MEAN MONTHLY

TEMPERATURES STILL ENDED UP A BIT ABOVE NORMAL BECAUSE THE FIRST

HALF OF APRIL WAS DOMINATED BY WARMER AIRMASSES ASSOCIATED WITH THE

RIDGE RESPONSIBLE FOR THE RECORD MARCH WARMTH. EVEN SO...APRIL 2012

WAS COLDER OVERALL THAN MARCH AT A FEW PLACES BECAUSE MARCH WAS SO

EXTRAORDINARILY WARM. IN THE ABSENCE OF MANY MOISTURE LADEN LOW

PRESSURE SYSTEMS...APRIL WAS DRY. SINCE MOST OF THE PRECIPITATION

FELL AS RAIN...MOST PLACES SAW LITTLE SNOW IN APRIL.

 

THE WEATHER PATTERN IN MAY THROUGH JULY WAS DOMINATED BY THE

SOUTHWEST FLOW ALOFT AROUND THE STUBBORN UPPER RIDGE OVER THE

SOUTHEASTERN UNITED STATES. MEAN MONTHLY TEMPERATURES AVERAGED 3 TO

5 DEGREES ABOVE NORMAL IN MAY...2 TO 4 DEGREES ABOVE AVERAGE IN

JUNE...AND 3 TO 6 DEGREES ABOVE NORMAL IN JULY. AS A RESULT...THE

MAY THROUGH JULY PERIOD IN 2012 GOES DOWN IN THE RECORD BOOKS AS ONE

OF THE TOP THREE WARMEST MAY THROUGH JULY STRETCHES AT MANY

LOCATIONS. JULY 2012 IS NOW ONE OF THE WARMEST MONTHS ON RECORD.

 

THE INTERACTION BETWEEN DISTURBANCES ROTATING AROUND THE PERIPHERY

OF THE UPPER RIDGE AND THE WARM...MOIST AIR ADVECTED INTO THE UPPER

GREAT LAKES BY THE SOUTHWEST FLOW RESULTED IN EPISODES OF HEAVY RAIN

SHOWERS AND THUNDERSTORMS. IRONWOOD PICKED UP 11.01 INCHES OF RAIN

IN MAY AND JUNE...OVER 160 PERCENT OF NORMAL FOR THOSE TWO MONTHS. A

NUMBER OF THESE THUNDERSTORMS TURNED SEVERE...ESPECIALLY IN JUNE AND

JULY. ONE THUNDERSTORM IN THE EVENING ON 6/8 SPAWNED A TORNADO OVER

NORTHWEST MARQUETTE COUNTY. SEVERE THUNDERSTORMS WERE MOST FREQUENT

THE FIRST WEEK OF JULY...WHEN THERE WERE NUMEROUS REPORTS OF

90-DEGREE HIGH TEMPERATURES.

 

THE DRIEST WEATHER PREVAILED OVER THE EAST AND SOUTH CENTRAL IN MAY

AND AGAIN OVER THE SOUTH CENTRAL IN JUNE. THE COMBINATION OF THE

WARM AND DRY WEATHER OVER THE EAST IN MAY SET THE STAGE FOR A COUPLE

OF DESTRUCTIVE FIRES THAT STRUCK LUCE AND SCHOOLCRAFT COUNTIES.

SOUTH WINDS GUSTING AS HIGH AS 50 MPH AHEAD OF AN APPROACHING COLD

FRONT CAUSED THE DUCK LAKE FIRE IN LUCE COUNTY TO SPREAD OUT OF

CONTROL ON 5/24. BEFORE THIS FIRE WAS FINALLY BROUGHT UNDER CONTROL

IN JUNE...OVER 21000 ACRES HAD BURNED.

 

FOR THE FIRST TIME IN SEVERAL MONTHS...AN UPPER TROUGH DOMINATED THE

GREAT LAKES FOR A COUPLE OF WEEKS IN MID-AUGUST. BUT THE THE MONTHLY

MEAN TEMPERATURE STILL AVERAGED A BIT ABOVE NORMAL THANKS TO A LATE

MONTH WARM SPELL AS THE RESILIENT UPPER RIDGE REBOUNDED BACK INTO

THE GREAT LAKES. DESPITE THE PRESENCE OF THE TROUGH FOR MUCH OF THE

TIME...AUGUST PRECIPITATION WAS BELOW AVERAGE EVERYWHERE AND WELL

BELOW NORMAL OVER THE SOUTH CENTRAL DUE TO AN ABSENCE OF LARGER

SCALE...MOISTURE-LADEN LOW PRESSURE SYSTEMS.

 

THE WEATHER PATTERN IN SEPTEMBER FEATURED A TRANSITION FROM THE

UPPER RIDGE EARLY IN THE MONTH TO A DEEP TROUGH THAT DOMINATED THE

GREAT LAKES THE SECOND HALF AND THROUGH OCTOBER INTO EARLY NOVEMBER.

THERE WAS RECORD WARMTH AND SOME SEVERE THUNDERSTORMS ON LABOR DAY

DURING THE PERIOD OF CHANGEABLE WEATHER THAT MARKED THIS

TRANSITION...BUT SEPTEMBER MEAN MONTHLY TEMPERATURES ENDED UP 1 TO 3

DEGREES BELOW NORMAL DUE TO THE VERY COOL WEATHER THAT PREVAILED THE

SECOND HALF OF THE MONTH. IN FACT...SEPTEMBER 2012 WAS THE FIRST

MONTH SINCE SEPTEMBER 2011 WITH A BELOW AVERAGE MONTHLY TEMPERATURE

OVER THE MAJORITY OF UPPER MICHIGAN. ALTHOUGH THERE WERE FEW LARGER

SCALE LOW PRESSURE SYSTEMS...THE COOL FLOW UNDER THE UPPER TROUGH

OVER THE RELATIVELY WARM WATERS OF LAKE SUPERIOR CAUSED NUMEROUS

LAKE EFFECT RAIN SHOWERS AND ABOVE NORMAL PRECIPITATION ACROSS AREAS

NEAR THE BIG LAKE IN SEPTEMBER. SOME HIGHER TERRAIN LOCATIONS SAW

THE FIRST SNOW FLAKES OR ICE PELLETS OF THE SEASON DURING THE COOLER

OUTBREAKS. AS MUCH AS 6.5 INCHES OF RAIN FELL AT MUNISING...OVER 150

PERCENT OF THE SEPTEMBER NORMAL. BUT THE SOUTH CENTRAL WAS DRY AGAIN

AWAY FROM THIS MOISTURE SOURCE. IRON MOUNTAIN REPORTED ONLY 1.97

INCHES...55 PERCENT OF NORMAL SEPTEMBER RAINFALL FOR THAT SITE.

 

MEAN MONTHLY TEMPERATURES IN OCTOBER WERE UP TO 2 DEGREES BELOW

NORMAL AS THE UPPER TROUGH TENDED TO DOMINATE. BUT WITH A CHANGEABLE

PATTERN AT TIMES...A NUMBER OF DEEPER LOW PRESSURE SYSTEMS IMPACTED

THE UPPER GREAT LAKES. EXCEPT FOR A FEW PLACES NEAR THE WISCONSIN

BORDER...THE RESULT WAS ABOVE NORMAL OCTOBER PRECIPITATION. AS WAS

THE CASE IN SEPTEMBER...THE HEAVIEST PRECIPITATION TENDED TO OCCUR

NEAR LAKE SUPERIOR WHERE WARMING AND MOISTENING OFF THE WATER TENDED

TO ENHANCE PRECIPITATION AMOUNTS. FOR THE SECOND MONTH IN A ROW...

MUNISING LOGGED THE HEAVIEST PRECIPITATION WITH 6.06 INCHES...NEARLY

150 PERCENT OF NORMAL. MANY PLACES AWAY FROM THE MODERATING

INFLUENCE OF THE GREAT LAKES PICKED UP THEIR FIRST ACCUMULATING

SNOWS OF THE SEASON IN OCTOBER...WITH AS MUCH AS 14 INCHES FALLING

AT HERMAN IN BARAGA COUNTY THROUGH THE MONTH.

 

AFTER SOME CHILLY WEATHER UNDER THE LINGERING UPPER TROUGH THE FIRST

WEEK OF NOVEMBER...THE PATTERN TURNED UNSEASONABLY WARM THE MIDDLE

OF THE MONTH AS AN UPPER RIDGE DOMINATED THE GREAT LAKES. ALTHOUGH

THE TROUGH RETURNED TO THE GREAT LAKES AND BROUGHT MORE SEASONABLE

CONDITIONS THE LAST WEEK OF NOVEMBER...THE MEAN MONTHLY TEMPERATURE

ENDED UP A LITTLE OVER A DEGREE ABOVE NORMAL AT MOST SPOTS. SINCE

THERE WERE RELATIVELY FEW LARGE-SCALE LOW PRESSURE SYSTEMS...MONTHLY

PRECIPITATION AND SNOWFALL WERE BELOW NORMAL AT MOST PLACES...

ESPECIALLY OVER THE SOUTH CENTRAL AWAY FROM MOISTENING AND

ENHANCEMENT OFF LAKE SUPERIOR. TWIN LAKES IN HOUGHTON COUNTY LED

REPORTING STATIONS WITH 35 INCHES OF SNOW IN NOVEMBER. BUT MOST

PLACES OVER THE SOUTH CENTRAL PICKED UP NO MORE THAN ABOUT 2 INCHES

OF THE WHITE STUFF THE ENTIRE MONTH.

 

IN DECEMBER...A WEST-TO-EAST FLOW OF PACIFIC AIR DOMINATED MOST OF

THE TIME...ESPECIALLY THE FIRST 3 WEEKS. DESPITE THE DEVELOPMENT OF

AN UPPER TROUGH AND A RETURN OF MORE SEASONABLE CANADIAN AIRMASSES 

THE LAST 10 DAYS OF DECEMBER...THE MONTHLY MEAN TEMPERATURE WAS 4 TO

6 DEGREES ABOVE AVERAGE...HIGH ENOUGH TO QUALIFY THE MONTH AS ONE OF

THE TOP 10 WARMEST DECEMBERS AT SOME PLACES. SINCE ONLY ONE

SIGNIFICANT LOW PRESSURE SYSTEM INFLUENCED THE AREA IN DECEMBER...

MONTHLY PRECIPITATION AND SNOWFALL RAN BELOW NORMAL. IN FACT...

DECEMBER 2012 IS NOW ONE OF THE TOP TEN DRIEST AND LEAST SNOWY

TWELFTH MONTHS ON RECORD AT A NUMBER OF PLACES. THE COMBINATION OF

THE UNSEASONABLE WARMTH AND RELATIVELY LITTLE PRECIPITATION AND SNOW

THROUGH MID-MONTH MEANT MANY LOCATIONS WOULD HAVE BARE GROUND UNTIL

ALMOST THE FIRST DAY OF WINTER. BUT A DEEP LOW PRESSURE SYSTEM

MOVING FROM THE PLAINS THROUGH THE GREAT LAKES ON 12/20 AS THE

WEATHER PATTERN WAS SHIFTING TOWARD A TROUGH IN EASTERN NORTH

AMERICA DELIVERED A WIDESPREAD SNOW THAT EXCEEDED A FOOT AT A FEW

PLACES OVER THE NORTH CENTRAL AND EAST JUST IN TIME FOR CHRISTMAS.

AS MUCH AS 16.7 INCHES OF SNOW BLANKETED NEGAUNEE IN MARQUETTE

COUNTY ON 12/20 INTO 12/21.

12/31/12 DAILY MEAN       600.5/601.5/-1.0  576.1/578.4/-2.3

 

THE COMBINATION OF EVAPORATION ENHANCED BY WELL ABOVE NORMAL

TEMPERATURES AND LACK OF ANY APPRECIABLE WINTER ICE AS WELL AS

SEVERE DROUGHT MUCH OF THE YEAR IN THE LAKE MICHIGAN DRAINAGE BASIN

CAUSED WATER LEVELS ON LAKES MICHIGAN AND HURON TO PLUMMET THROUGH

THE YEAR TO RECORD LOW LEVELS ALMOST 30 INCHES BELOW NORMAL IN LATE

NOVEMBER AND DECEMBER. OVERALL...PRECIPITATION IN THE LAKE SUPERIOR

DRAINAGE BASIN WAS HEAVIER IN 2012...SO WATER LEVELS ON THAT LAKE

REMAINED NEARLY STEADY ABOUT A FOOT BELOW AVERAGE DESPITE THE

ENHANCED EVAPORATION.
