...WATER LEVELS FALL BUT REMAIN ABOVE NORMAL IN OCTOBER...

EVEN THOUGH THE OBSERVED GREAT LAKES WATER LEVELS FELL DURING
OCTOBER DUE TO THE DRIER WEATHER LAST MONTH, THE WELL ABOVE NORMAL
WATER LEVELS AT THE END OF SEPTEMBER ENSURED THE LAKES REMAINED
ABOVE AVERAGE THROUGH 10/31. AT THE END OF OCTOBER, WATER LEVELS ON
LAKE SUPERIOR WERE 4 TO 5 INCHES ABOVE NORMAL AND AROUND AN INCH
HIGHER THAN OBSERVED IN OCTOBER 2015. THE LEVEL ON LAKES MICHIGAN
AND HURON REMAINED 8 TO 9 INCHES ABOVE NORMAL AT THE END OF THE
MONTH AND 2 TO 3 INCHES HIGHER THAN IN OCTOBER 2015.

                      OCTOBER CLIMATE HIGHLIGHTS

HIGHEST REPORTED TEMPERATURE...75 AT PELKIE IN BARAGA COUNTY ON 10/6
                                AND MENOMINEE ON 10/17

LOWEST REPORTED TEMPERATURE...20 AT STAMBAUGH IN IRON COUNTY ON 10/25

HIGHEST AVERAGE TEMPERATURE...50.6 DEGREES AT MARQUETTE CITY

LOWEST AVERAGE TEMPERATURE...43.7 DEGREES AT HERMAN IN BARAGA COUNTY

HIGHEST MONTHLY PRECIPITATION...7.13 INCHES AT MUNISING

LOWEST MONTHLY PRECIPITATION...2.39 INCHES AT THE HOUGHTON COUNTY
                                AIRPORT

HIGHEST MONTHLY SNOWFALL...0.6 INCH AT NEWBERRY

OCTOBER 2016 PRECIPITATION ENDED UP BELOW NORMAL AT MOST PLACES BUT
DEPENDED ON HOW MUCH RAIN FELL AT SOME LOCATIONS DURING TWO HEAVY
PRECIPITATION EVENTS THAT IMPACTED UPPER MICHIGAN ON 10/17 AND
10/18. THE PLACES THAT SAW THE HEAVIEST RAIN DURING THIS TIME WERE
ON AN AXIS FROM NEAR IRON MOUNTAIN TO MUNISING, WHICH WERE IMPACTED
BY A SLOW MOVING CLUSTER OF HEAVY THUNDERSTORMS THAT DROPPED
TORRENTIAL DOWNPOURS AND DIME-SIZED HAIL AS WELL AS CAUSING SOME
GUSTY WINDS FROM LATE ON 10/17 INTO THE EARLY MORNING HOURS ON 10/18
AHEAD OF A SLOW MOVING COLD FRONT. MANY LOCATIONS IN THIS AREA SAW
BETWEEN 3 TO 5 INCHES OF RAIN, WITH AS MUCH AS 5.10 INCHES NEAR
GWINN IN MARQUETTE COUNTY AND 4.16 INCHES AT CHATHAM IN ALGER
COUNTY. THIS TORRENTIAL RAINFALL CAUSED SOME FLOODING, ESPECIALLY
ALONG THE CHOCOLAY RIVER IN MARQUETTE COUNTY THAT RESULTED IN WASHED
OUT BRIDGES, CLOSED ROADS AND SOME EVACUATIONS. THE FIRST HEAVY
PRECIPITATION EVENT THAT IMPACTED UPPER MICHIGAN DURING THE NIGHT ON
10/16-10/17 TO THE NORTH OF AN APPROACHING WARM FRONT FEATURED SOME
STRONG THUNDERSTORMS THAT DROPPED HAIL UP TO AN INCH IN DIAMETER AND
CAUSED GUSTY WINDS AS HIGH AS 50 MPH.

IN THE AREA THAT SAW THE HEAVIEST RAIN ON 10/17 INTO 10/18, TOTAL
OCTOBER RAINFALL REACHED AS MUCH AS 7.13 INCHES AT MUNISING, THE
FOURTH HIGHEST AMOUNT OBSERVED IN ANY OCTOBER AT THAT LOCATION AND
170 PERCENT OF THE MONTHLY AVERAGE. CHATHAM WAS CLOSE BEHIND WITH
6.90 INCHES OF OCTOBER RAINFALL. AT THOSE PLACES THAT MISSED THE
HEAVIER PRECIPITATION AND SAW LESS THAN AN INCH OF RAIN ON 10/17
INTO 10/18, OCTOBER PRECIPITATION TOTALS WERE UNDER 3 INCHES. THE
2.39 INCHES OF RAIN THAT FELL AT THE HOUGHTON COUNTY AIRPORT IS ONLY
ABOUT 80 PERCENT OF THE MONTHLY AVERAGE THERE.

AS WAS THE CASE IN SEPTEMBER, A WARM PACIFIC FLOW OF AIR DOMINATED
THE WEATHER PATTERN ACROSS THE GREAT LAKES IN OCTOBER 2016. THE
RESULT WAS ANOTHER RELATIVELY WARM MONTH ACROSS UPPER MICHIGAN. MEAN
OCTOBER TEMPERATURES RANGING FROM ABOUT 44 TO 51 DEGREES ARE 3 TO 5
DEGREES ABOVE THE 30-YEAR NORMAL AND 11 TO 14 DEGREES LOWER THAN THE
SEPTEMBER MONTHLY AVERAGES. DURING THE WARMER PERIODS, AT LEAST ONE
SPOT IN UPPER MICHIGAN SAW THE MERCURY CLIMB TO 70 OR HIGHER EACH
DAY FROM 10/2 THROUGH 10/6, ON 10/10 AND AGAIN ON 10/17.

JUST LIKE IN AUGUST AND SEPTEMBER, THE OCTOBER WARMTH WAS DUE MAINLY
TO WELL ABOVE NORMAL MINIMUM TEMPERATURES. FOR INSTANCE AT NEWBERRY,
THE AVERAGE OCTOBER LOW TEMPERATURE WAS 41.5 DEGREES, 4.7 DEGREES
ABOVE NORMAL WHILE THE 55.7 DEGREE MEAN MAXIMUM TEMPERATURE WAS ONLY
1.9 DEGREES ABOVE AVERAGE. THERE WERE NO MINIMUM TEMPERATURES IN THE
TEENS DURING OCTOBER 2016. EVEN SO, READINGS FELL OFF INTO THE 20S
ON 10/9, 10/13, 10/14, EACH DAY FROM 10/20 THROUGH 10/26, ON 10/28
AND 10/31.

DUE TO ABOVE NORMAL WARMTH, OCTOBER SNOWFALL WAS NEGLIGIBLE.  IN
FACT, THE ONLY ACCUMULATING SNOW DURING THE MONTH OCCURRED DURING
THE NIGHT ON 10/26-10/27, WHEN UP TO AN INCH OF WET SNOW FELL AROUND
NEWBERRY ON THE NORTHERN FLANK OF THE PRECIPITATION SHIELD
ASSOCIATED WITH SURFACE LOW PRESSURE MOVING THROUGH THE LOWER GREAT
LAKES.

                         DECEMBER CLIMATOLOGY

TEMPERATURES CONTINUE THEIR DOWNWARD SLIDE IN DECEMBER AS WINTER
ARRIVES IN THE NORTHERN HEMISPHERE.  AVERAGE MONTHLY TEMPERATURES IN
DECEMBER ACROSS UPPER MICHIGAN ARE AS MUCH AS 12 DEGREES LOWER THAN
IN NOVEMBER AS TOTAL POSSIBLE SUNSHINE DECLINES TO 514 MINUTES
AROUND THE WINTER SOLSTICE. WINTER OFFICIALLY BEGINS THIS YEAR AT
5:44 AM EST ON 12/21. ON THAT DAY...THE SUN RISES TO ONLY ABOUT 20
DEGREES ABOVE THE SOUTHERN HORIZON AT LOCAL NOON IN UPPER MICHIGAN.

ARCTIC INVASIONS ARE COMMON ACROSS THE NORTHWEST GREAT LAKES IN
DECEMBER...RESULTING IN CONSIDERABLE CLOUD COVER AND LAKE EFFECT
SNOW. AS THE COLD AIR PASSES OVER THE RELATIVELY WARM WATERS OF LAKE
SUPERIOR...THE AIRMASS BECOMES INCREASINGLY UNSTABLE. THE RESULT IS
A GREATER FREQUENCY OF LOW CLOUD AND SNOW SHOWERS...WHICH ARE
TYPICALLY HEAVIER AND MORE WIDESPREAD OVER HIGHER TERRAIN JUST
DOWNWIND OF LAKE SUPERIOR. THE LOCATION OF MAXIMUM SNOWFALL IS VERY
DEPENDENT ON THE LOW LEVEL WIND DIRECTION BECAUSE THE LONGEST WIND
FETCH ACROSS THE WATER RESULTS IN GREATEST DESTABILIZATION. A WEST
WIND FAVORS THE KEWEENAW PENINSULA; A NORTHWEST WIND USUALLY RESULTS
IN HEAVIER SNOW AROUND ONTONAGON AND IN ALGER AND LUCE COUNTIES; AND
A NORTH TO NORTHEAST WIND CAUSES THE HEAVIEST SNOW AROUND IRONWOOD
AND IN THE NORTH CENTRAL HIGHLANDS OF BARAGA AND MARQUETTE COUNTIES.
ALTHOUGH LARGE SCALE STORM SYSTEMS THAT TYPICALLY MOVE NORTHEAST
FROM THE PLAINS STATES INTO THE GREAT LAKES CAN ALSO BRING HEAVY
SNOW TO INLAND LOCATIONS...AVERAGE DECEMBER PRECIPITATION IS QUITE A
BIT LESS AWAY FROM LAKE SUPERIOR.  FOR INSTANCE...THE HOUGHTON
COUNTY AIRPORT PICKS UP 52.9 INCHES OF SNOW DURING A TYPICAL
DECEMBER. IRON MOUNTAIN WILL RECEIVE ONLY 13.9 INCHES OF SNOW AND
1.55 INCHES OF LIQUID EQUIVALENT PRECIPITATION ON AVERAGE. THE
HOUGHTON COUNTY AIRPORT WAS BURIED UNDER 119 INCHES OF SNOW IN
DECEMBER 1978. RECORD SNOWS AT INLAND LOCATIONS ARE CLOSER TO 36
INCHES. IN MORE RECENT YEARS...HEAVY SNOW FELL IN DECEMBER IN
2008...2000...1996 AND 1995 AT MANY LOCATIONS. ROCKLAND IN ONTONAGON
COUNTY MEASURED 127 INCHES OF THE WHITE STUFF IN DECEMBER 2000. IN
DECEMBER 2008...TWIN LAKES IN HOUGHTON COUNTY LOGGED ALMOST 106
INCHES.

ALTHOUGH LAKE SUPERIOR OFTEN MODERATES THE CHILL OF THE ARCTIC
AIR...BELOW ZERO READINGS ARE COMMON DURING THE TWELFTH MONTH.
RECORD LOW TEMPERATURES ARE AS LOW AS 36 BELOW ZERO AT IRONWOOD...
OBSERVED DURING A BRUTAL COLD SNAP IN MID DECEMBER 1983 THAT ALSO
DROPPED THE TEMPERATURE TO A MONTHLY RECORD 28 BELOW ZERO AT THE
MARQUETTE NWS. THE LOWEST TEMPERATURES RECORDED AT MANY LOCATIONS IN
UPPER MICHIGAN OCCURRED DURING AN ARCTIC OUTBREAK AT THE END OF
DECEMBER 1976...INCLUDING 26 BELOW ZERO AT IRON MOUNTAIN...25 BELOW
ZERO AT MANISTIQUE...21 BELOW ZERO AT MUNISING AND 15 BELOW ZERO AT
THE HOUGHTON COUNTY AIRPORT. DECEMBER 1985 AND DECEMBER 1989 ALSO
SAW FREQUENT ARCTIC INVASIONS WITH MONTHLY TEMPERATURES AVERAGING AS
MUCH 10 DEGREES BELOW NORMAL. A COLD WAVE ARRIVED IN DECEMBER 2004
JUST BEFORE CHRISTMAS. MORNING LOWS ON CHRISTMAS DAY THAT YEAR FELL
AS LOW AS 34 BELOW ZERO AT CHAMPION IN MARQUETTE COUNTY. MORE
RECENTLY...DECEMBER 2013 FEATURED VERY COLD WEATHER MOST OF THE TIME
AND A MEAN DAILY TEMPERATURE THAT ENDED UP BETWEEN 6 AND 10 DEGREES
BELOW NORMAL. IN FACT...DECEMBER 2013 GOES DOWN IN THE RECORD BOOKS
AMONG THE TOP 10 COLDEST ACROSS UPPER MICHIGAN.

BUT JUST TWO YEARS LATER IN DECEMBER 2015...A PERSISTENT FLOW OF
PACIFIC AIR RELATED TO A RECORD STRONG EL NINO EVENT BROUGHT SOME
RECORD MONTHLY WARMTH TO UPPER MICHIGAN...WITH MEAN MONTHLY
TEMPERATURES RUNNING 9 TO 12 DEGREES ABOVE NORMAL. ALTHOUGH NUMEROUS
LOW PRESSURE SYSTEMS IMPACTED UPPER MICHIGAN THAT MONTH WITH WELL
ABOVE NORMAL PRECIPITATION...INCLUDING THE HIGHEST DECEMBER
PRECIPITATION TOTALS ON RECORD AT IRON MOUNTAIN AND MANISTIQUE...THE
OVERALL WARMTH RESULTED IN WELL BELOW NORMAL SNOWFALL...ESPECIALLY
LAKE EFFECT SNOW. MUNISING SAW A RECORD LOWEST DECEMBER SNOWFALL IN
2015 WITH ONLY 5.5 INCHES OF THE WHITE STUFF FALLING THE ENTIRE
MONTH. ALTHOUGH BROWN CHRISTMASES ARE RARE IN UPPER MICHIGAN...MANY
LOCATIONS IN 2015 AWAY FROM THE HIGHER TERRAIN OF THE WEST HALF HAD
LITTLE IF ANY SNOW ON THE GROUND TO GREET SANTA CLAUS.

DECEMBER 1994 ALSO GOES DOWN IN THE RECORD BOOKS AS ONE OF THE
WARMEST AND LEAST SNOWY IN UPPER MICHIGAN HISTORY WITH TEMPERATURES
AS MUCH AS 10 DEGREES ABOVE NORMAL AND MANY PLACES PICKING UP LESS
THAN 10 INCHES OF TOTAL SNOW. MANY LOCATIONS ALSO HAD A BROWN
CHRISTMAS IN 1994. MANY RECENT DECEMBERS HAVE ALSO BEEN ON THE MILD
SIDE. IN DECEMBER 2006...MONTHLY TEMPERATURES AVERAGED 5 TO 8
DEGREES ABOVE THE MEAN ACROSS UPPER MICHIGAN. SINCE SNOWFALL OVER
MUCH OF UPPER MICHIGAN WAS ALSO BELOW NORMAL... MANY AREAS EAST OF
CRYSTAL FALLS AND THE HURON MOUNTAINS SAW A BROWN CHRISTMAS IN 2006.
DECEMBER 2001 WAS ALSO VERY WARM. SOME RARE DECEMBER SEVERE
THUNDERSTORMS ON 12/5/2001 FORMED IN A RECORD WARM AIRMASS AHEAD OF
A COLD FRONT AND PUMMELED IRON AND DICKINSON COUNTIES WITH LARGE
HAIL. ALTHOUGH DECEMBER 2002 STARTED ON A COLD NOTE...TEMPERATURES
THE LAST THREE WEEKS OF THE MONTH AVERAGED 10 DEGREES ABOVE NORMAL.
MANY PLACES NOT IMPACTED BY LAKE EFFECT SNOW HAD A BROWN CHRISTMAS
IN 2002.
