...GENERAL 2010 OVERVIEW...

THE BIG WEATHER STORIES OF 2010 ACROSS UPPER MICHIGAN INCLUDED:

...PERSISTENT WARM AND DRY WEATHER IN JANUARY THROUGH MAY THAT
FEATURED RECORD WARMTH AND DRYNESS AT SOME PLACES...

...A VERY WET JUNE THROUGH SEPTEMBER THAT FEATURED RECORD RAINFALL
AT SOME LOCATIONS...

...VERY WARM WEATHER IN JULY...AUGUST...OCTOBER AND NOVEMBER...

AFTER TWO FAIRLY COOL YEARS IN 2008 AND 2009...PERSISTENT WARMTH WAS
A HIGHLIGHT OF THE WEATHER IN 2010. IN FACT...THE ONLY MONTH WHEN
THE AVERAGE TEMPERATURE AT MOST PLACES WAS SIGNIFICANTLY BELOW
NORMAL WAS IN SEPTEMBER. EXCEPT FOR JUNE WHEN THE MONTHLY AVERAGE
TEMPERATURE WAS CLOSE TO THE MEAN...EVERY OTHER MONTH WAS WARMER
THAN NORMAL...BOOSTING THE 2010 ANNUAL TEMPERATURE TO 2 TO 4 DEGREES
ABOVE THE 1971-2000 AVERAGE. THE RESULT WAS A TOP FIVE WARMEST YEAR
AT MOST PLACES...INCLUDING THE SECOND WARMEST AT NEWBERRY...WHERE
RECORDS EXTEND BACK 100 YEARS.

ALTHOUGH THE FIRST FIVE MONTHS OF 2010 WERE QUITE DRY WITH RECORD
LOW JANUARY THROUGH MAY PRECIPITATION AS LITTLE AS 3.38 INCHES AT
IRON MOUNTAIN...THE PATTERN TURNED MUCH WETTER BEGINNING IN JUNE.
EVEN THOUGH AUGUST WAS NOT PARTICULARLY WET...RAINFALL IN JUNE...
JULY...AND SEPTEMBER WAS SO HEAVY WITH SOME RECORD MONTHLY RAINFALL
AT SEVERAL SITES THE JUNE THROUGH SEPTEMBER PERIOD WAS AMONG THE TOP
5 WETTEST ON RECORD AT MANY LOCATIONS. AS MUCH AS 10.72 INCHES OF
RAIN INUNDATED GARDEN CORNERS IN DELTA COUNTY IN SEPTEMBER. OVER 2
FEET OF RAIN FELL AT MUNISING BETWEEN 6/1 AND 9/30...ADDING UP TO
26.71 INCHES...OVER 200 PERCENT OF NORMAL FOR THESE FOUR MONTHS.
ALTHOUGH OCTOBER THROUGH DECEMBER PRECIPITATION WAS GENERALLY BELOW
AVERAGE AT MOST LOCATIONS...THE JUNE THROUGH SEPTEMBER PERIOD WAS SO
WET THAT MOST LOCATIONS ENDED 2010 WITH A SURPLUS. THE ONLY
EXCEPTION WAS OVER NORTHWEST UPPER MICHIGAN... WHERE ONTONAGON SAW
ITS DRIEST YEAR SINCE AT LEAST 1977. ONLY A LITTLE OVER 25 INCHES OF
WATER EQUIVALENT PRECIPITATION FELL THERE IN 2010...ABOUT 10 INCHES
LESS THAN IN 2009.

SINCE JANUARY THROUGH MAY ENDED UP SO DRY AND WARM...CALENDAR YEAR
SNOWFALL IN 2010 WAS BELOW NORMAL AT MOST SPOTS. THE DEFICITS WERE
MOST PRONOUNCED AWAY FROM THE NORTH WIND SNOW BELTS BECAUSE WHEN
LAKE EFFECT SNOW DID OCCUR IN JANUARY AND FEBRUARY...THIS
PRECIPITATION WAS HEAVIEST IN THOSE AREAS. SO CALENDAR YEAR SNOWFALL
AT IRONWOOD AND THE MARQUETTE NWS OFFICE IN MARQUETTE COUNTY WAS
CLOSER TO NORMAL THAN AT MOST OTHER LOCATIONS. IRON MOUNTAIN PICKED
UP ONLY 26.7 INCHES OF SNOW IN ALL OF 2010...THE LOWEST ANNUAL
SNOWFALL ON RECORD THERE. JUST 112.5 INCHES OF THE WHITE STUFF FELL
AT HOUGHTON...OVER 100 INCHES BELOW NORMAL AND THE SECOND LOWEST
CALENDAR YEAR TOTAL ON RECORD.

GREAT LAKES WATER LEVELS FELL WELL BELOW NORMAL DURING 2010...
MOST LIKELY DUE TO LONG TERM PRECIPITATION DEFICITS SINCE SUMMER
2008 AND THE WELL ABOVE NORMAL TEMPERATURES OBSERVED IN 2010 THAT
MINIMIZED ICE COVER AND INCREASED EVAPORATION.
