...GREAT LAKES WATER LEVELS FALL SLOWLY IN OCTOBER...

AFTER A SIGNIFICANT RISE DURING SPRING AND EARLY SUMMER...THE WATER
LEVEL ON LAKES MICHIGAN/HURON FELL SLOWLY IN OCTOBER...ABOUT 1 TO
1.5 INCHES TO AROUND 18 INCHES BELOW THE NORMAL LEVEL ON 10/31...
DUE TO INCREASED EVAPORATION AND LOWER PRECIPITATION IN LATE SUMMER.
BUT EVEN WITH THIS SLOW DECLINE...THE WATER LEVEL ON THESE LAKES AT
THE END OF OCTOBER IS STILL ALMOST 10 INCHES HIGHER THAN LAST YEAR
AT THIS SAME TIME. WATER LEVELS ON LAKE SUPERIOR ALSO FELL SLOWLY TO
ABOUT 3 TO 4 INCHES BELOW THE LONG TERM AVERAGE AT THE END OF THE
MONTH.

TWO DISTINCT UPPER AIR PATTERNS DOMINATED THE WEATHER ACROSS THE
GREAT LAKES IN OCTOBER 2013. DURING THE FIRST HALF OF THE MONTH...
THIS PATTERN FEATURED A TROUGH OVER WESTERN NORTH AMERICA AND A
RIDGE ACROSS THE EAST. THE SOUTHWEST FLOW BETWEEN THESE LARGER SCALE
FEATURES RESULTED IN UNSEASONABLY MILD WEATHER THE FIRST TWO WEEKS
OF OCTOBER...WITH MEAN DAILY TEMPERATURES AVERAGING AS MUCH AS 20
DEGREES ABOVE NORMAL WHEN THE WARMEST WEATHER PREVAILED ON 10/1 INTO
10/2 AND AGAIN ON 10/9 AND 10/10. THE MERCURY TOPPED OUT AS HIGH AS
80 DEGREES AT A FEW PLACES ON 10/1 AND 10/2...AND READINGS PEAKED IN
THE 70S AGAIN AT MANY PLACES EACH DAY FROM 10/8 THROUGH 10/12.

DURING THE SECOND HALF OF THE MONTH...AN UPPER RIDGE BUILT OVER
WESTERN NORTH AMERICA...CAUSING AN UPPER TROUGH TO DEEPEN ACROSS
CENTRAL AND EASTERN NORTH AMERICA. MEAN DAILY TEMPERATURES FROM
10/15 THROUGH 10/30 RAN BELOW NORMAL ALMOST EVERY DAY...FALLING TO
AROUND 10 DEGREES BELOW AVERAGE DURING THE COLDEST TIME ON 10/28 AND
10/29. THE THERMOMETER BOTTOMED OUT IN THE TEENS AT A FEW PLACES ON
10/25 AND AGAIN ON 10/29.

SINCE THE WARMTH DURING THE FIRST HALF OF THE MONTH WAS MORE
ANOMALOUS...THE OVERALL MEAN MONTHLY TEMPERATURE ENDED UP FROM ABOUT
0.5 TO 1.5 DEGREES ABOVE NORMAL. THE OCTOBER MEAN TEMPERATURE
BETWEEN ABOUT 42 AND 49 DEGREES WAS 10 TO 13 DEGREES LOWER THAN
REPORTED OVER THE AREA IN SEPTEMBER.

EXCEPT FOR AN AREA THAT INCLUDED PORTIONS OF THE SOUTH CENTRAL
EXTENDING NORTHEAST TO MUNISING AND NEWBERRY AS WELL AS THE NORTHERN
PART OF THE KEWEENAW PENINSULA...MOST OF WEST AND CENTRAL UPPER
MICHIGAN REPORTED ABOVE NORMAL PRECIPITATION IN OCTOBER. MONTHLY
TOTALS WERE AS HIGH AS 5 INCHES OR MORE OVER THE FAR WEST...WHERE
IRONWOOD LED REPORTING STATIONS WITH 5.34 INCHES...ABOUT 135 PERCENT
OF THE OCTOBER NORMAL. 2013 HAS BEEN A PARTICULARLY WET YEAR AT
IRONWOOD. IN FACT...THE 5.34 INCHES LIFTED THE ANNUAL PRECIPITATION
AT IRONWOOD TO 47.72 INCHES...WHICH IS THE GREATEST JANUARY THROUGH
OCTOBER TOTAL ON RECORD THERE SINCE RECORDS BEGAN AT THAT SITE IN
1901. OCTOBER PRECIPITATION OVER MUCH OF THE SOUTH CENTRAL WEST OF
ESCANABA WAS UNDER 3.00 INCHES...ABOUT 75 TO 85 PERCENT OF THE MEAN.
THE 2.01 INCHES THAT FELL AT COPPER HARBOR WAS ONLY ABOUT 60 PERCENT
OF THE OCTOBER NORMAL.

A MOIST SOUTHWEST FLOW AHEAD OF LOW PRESSURE THAT TOOK SHAPE IN THE
PLAINS ON 10/3 BEFORE MOVING INTO THE NORTHWEST GREAT LAKES CAUSED A
PERIOD OF MODERATE RAINFALL OVER UPPER MICHIGAN FROM LATE ON 10/2
INTO 10/6. SOME LATE SEASON THUNDERSTORMS ENHANCED THE RAINFALL
DURING THE NIGHT ON 10/4-10/5 AND INTO THE DAY ON 10/5. MOST PLACES
LOGGED 1.00 TO 2.00 INCHES OF RAIN DURING THIS TIME...WITH AS MUCH
AS 2.43 INCHES FALLING AT WATERSMEET IN GOGEBIC COUNTY. THE ONLY
AREA THAT SAW LESS THAN AN INCH OF RAIN WAS OVER THE KEWEENAW...
WHERE ONLY 0.64 INCH FELL AT COPPER HARBOR ON 10/2 THROUGH 10/6.

UNDER THE HIGH PRESSURE SYSTEM THAT BROUGHT WARM AND DRY WEATHER TO
UPPER MICHIGAN DURING THE SECOND WEEK OF OCTOBER...AREAS OF DENSE
FOG THAT RESTRICTED VISIBILITY UNDER ONE QUARTER MILE AT MANY
LOCATIONS DEVELOPED DURING THE NIGHTS ON 10/9-10/10 AND 10/10-10/11.
A BAND OF SHOWERS AND A FEW EMBEDDED THUNDERSTORMS AHEAD OF THE COLD
FRONT THAT MARCHED ACROSS UPPER MICHIGAN ON 10/12 AND ENDED THIS
ROUND OF UNSEASONABLE WARMTH DROPPED AN INCH OR MORE OF RAIN AT SOME
LOCATIONS NEAR LAKE MICHIGAN. MANISTIQUE LED REPORTING STATIONS WITH
1.26 INCHES OF RAIN ON 10/12.

FOLLOWING THE COLD FRONTAL PASSAGE ON 10/12...A SERIES OF OTHER
UPPER DISTURBANCES DEEPENED THE UPPER TROUGH OVER CENTRAL AND
EASTERN NORTH AMERICA AROUND MID-MONTH. ONE OF THE MORE SIGNIFICANT
LOW PRESSURE SYSTEMS PASSED THROUGH THE UPPER GREAT LAKES ON 10/15
INTO 10/16 AND DROPPED 0.25 TO 0.75 INCH OF RAIN AT MOST PLACES. THE
HEAVIEST RAIN FELL OVER THE WEST...WHERE AS MUCH AS 0.93 INCH AND
0.89 INCH FELL IN HOUGHTON COUNTY AT ATLANTIC MINE AND JACOBSVILLE
RESPECTIVELY. SOME LOCALLY DENSE FOG ALSO OCCURRED DURING THIS
RAINFALL.

THE FIRST ACCUMULATING SNOWS OF THE SEASON FELL OVER MAINLY THE
HIGHER TERRAIN OF THE WEST AND NORTH CENTRAL IN THE WAKE OF A LOW
PRESSURE SYSTEM MOVING FROM THE NORTHERN PLAINS ON 10/20 ACROSS THE
UPPER LAKES AND INTO SOUTHEAST CANADA ON 10/21. WEST TO NORTHWEST
WIND GUSTS UP TO 35 MPH OVER THE EXPOSED KEWEENAW PENINSULA ON 10/21
MADE AIR TEMPERATURES FALLING THROUGH THE 30S FEEL EVEN COLDER. THE
STEADY NORTHWEST FLOW OF CHILLY CANADIAN AIR THAT DROPPED MEAN DAILY
TEMPERATURES AS MUCH AS 10 DEGREES BELOW NORMAL PERSISTED FOR
SEVERAL DAYS AROUND A SHARP UPPER TROUGH THE DEVELOPED OVER
SOUTHEAST CANADA. LAKE EFFECT RAIN SHOWERS...WHICH WERE GENERALLY
SNOW OVER THE HIGHER TERRAIN OF THE WEST AND NORTH CENTRAL...WERE
COMMON FROM LATE ON 10/21 INTO 10/25. TOTAL WATER EQUIVALENT
PRECIPITATION DURING THESE DAYS APPROACHED AN INCH OVER THE FAVORED
HIGHER TERRAIN LOCATIONS...AND UP TO 6 TO 7 INCHES OF WET SNOW
ACCUMULATED DURING THIS TIME AT ATLANTIC MINE AND HERMAN. THE
APPROACH AND PASSAGE OF A HIGH PRESSURE RIDGE ON 10/25 ENDED THE
LAKE EFFECT RAIN AND SNOW SHOWERS.

SOUTHWEST WINDS GUSTED UP TO 35 TO 40 MPH LATE IN THE DAY ON 10/25
MAINLY AT EXPOSED LOCATIONS NEAR LAKE MICHIGAN BETWEEN THE DEPARTING
HIGH PRESSURE RIDGE AND YET ANOTHER APPROACHING DISTURBANCE EMBEDDED
IN THE DEEP UPPER TROUGH AND ITS ATTENDANT COLD FRONT. THE COLD
FRONT CROSSED UPPER MICHIGAN DURING THE NIGHT ON 10/25-10/26
ACCOMPANIED BY SOME RAIN SHOWERS THAT DROPPED UP TO 0.25 TO 0.35
INCH OF PRECIPITATION AT A FEW LOCATIONS. NORTHWEST WINDS BEHIND
THIS FRONT GUSTED UP TO 45 MPH INTO THE DAY ON 10/26. ANOTHER STRONG
COLD FRONT ACCOMPANIED BY WIND GUSTS UP 40 MPH AND SOME RAIN AND
SNOW SHOWERS SURGED THROUGH THE UPPER GREAT LAKES DURING THE NIGHT
ON 10/27-10/28. BEHIND THIS FRONTAL PASSAGE...THE COLDEST AIRMASS OF
THE SEASON OVERSPREAD THE GREAT LAKES ON 10/28 AND 10/29. MEAN DAILY
TEMPERATURES ON BOTH THESE DAYS FELL TO 10 TO 15 DEGREES BELOW
AVERAGE. THE MERCURY SANK AS LOW AS 13 AT DAWN ON 10/29 AT KENTON IN
FAR SOUTHERN HOUGHTON COUNTY AND CLARKSBURG-CHAMPION IN MARQUETTE
COUNTY ON 10/29.

ONCE THE CANADIAN HIGH PRESSURE SYSTEM THAT MARKED THE CENTER OF
THIS COLD AIRMASS MOVED TO THE EAST ON 10/30...A SOUTHERLY FLOW
DEVELOPED AND DREW WARMER...MOISTER AIR BACK INTO THE UPPER LAKES.
AREAS OF DENSE FOG DEVELOPED EARLY ON 10/31. AS A LOW PRESSURE
SYSTEM LIFTED NORTHEAST FROM THE PLAINS AND THROUGH THE GREAT
LAKES...RAIN ALSO OVERSPREAD UPPER MICHIGAN ON HALLOWEEN. THE RAIN
WAS HEAVIEST OVER THE SOUTH CENTRAL AND EAST CLOSER TO THE TRACK OF
THE LOW PRESSURE SYSTEM IN THE EVENING ON 10/31. AN INCH OR MORE OF
RAIN FELL AT MANY LOCATIONS IN THIS AREA...WITH UP TO 1.48 INCHES
NEAR BARK RIVER IN DELTA COUNTY. THIS HEAVY RAIN PRESENTED A
CHALLENGE FOR TRICK-OR-TREATERS GOING OUT TO GET HALLOWEEN CANDY.
RAINFALL OVER WESTERN UPPER MICHIGAN WAS GENERALLY LESS THAN 0.50
INCH.
---------------------------------------------------------------------
                  ...VERY WET SINCE LAST WINTER...

DESPITE THE GENERALLY DRY WEATHER IN SEPTEMBER...PRECIPITATION IN
THE MARCH THROUGH AUGUST TIME PERIOD WAS SO HEAVY THAT THE MARCH
THROUGH OCTOBER 2013 TIME PERIOD STILL RANKS AMONG THE TOP 25

                         DECEMBER FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING EQUAL CHANCES OF
AN ABOVE AND BELOW NORMAL MONTHLY MEAN TEMPERATURE AND ABOVE AND
BELOW NORMAL MONTHLY PRECIPITATION OVER ALL OF UPPER MICHIGAN IN
DECEMBER 2013.

                       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
12:11 PM 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 AND 3.25 INCHES OF
LIQUID EQUIVALENT PRECIPITATION DURING A TYPICAL DECEMBER. IRON
MOUNTAIN WILL RECEIVE ONLY 14.7 INCHES OF SNOW AND 1.48 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.

DECEMBER 1994 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. THE MARQUETTE NWS AND NEWBERRY ALL OBSERVED
THEIR WARMEST DECEMBER EVER. ALTHOUGH BROWN CHRISTMASES ARE RARE IN
UPPER MICHIGAN (BEFORE 1994 DOWNTOWN MARQUETTE OBSERVED A BROWN
CHRISTMAS IN 1923...1931... 1941...1946...1957 AND 1982)...MANY
LOCATIONS THAT YEAR HAD LITTLE IF ANY SNOW ON THE GROUND TO GREET
SANTA CLAUS. TEMPERATURES ON CHRISTMAS EVE AND CHRISTMAS DAY IN 1994
WERE NEAR 50 OR EVEN HIGHER AT IRONWOOD...IRON MOUNTAIN... NEWBERRY
AND MARQUETTE. 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...AND THE MONTH ENDED
UP AS THE WARMEST DECEMBER ON RECORD AT THE HOUGHTON COUNTY AIRPORT.
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 THE WARMEST ON RECORD AT
MUNISING...MANISTIQUE...AND ONTONAGON. ON 12/5/2001...RARE DECEMBER
SEVERE THUNDERSTORMS FORMED IN A RECORD WARM AIRMASS AHEAD OF A COLD
FRONT AND PUMMELED IRON AND DICKINSON COUNTIES WITH LARGE HAIL.
IRON MOUNTAIN RECORDED ITS WARMEST DECEMBER IN 1997. THE FIRST
SEVERAL DAYS OF DECEMBER 1998 FEATURED RECORD WARMTH. MONTHLY RECORD
HIGH TEMPERATURES WERE SET AT IRON MOUNTAIN (64 ON 12/4)...IRONWOOD
(59 ON 12/4)...MANISTIQUE (59 ON 12/1) AND THE MARQUETTE NWS (59 ON
12/3). BUT THE ARRIVAL OF COLDER AIR AND HEAVY SNOW THE LAST HALF OF
DECEMBER 1998 PREVENTED THE MONTH FROM GOING DOWN AS ONE OF THE
WARMEST ON RECORD. 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.
