...GREAT LAKES WATER LEVELS REMAIN NEARLY STEADY IN NOVEMBER...

FOR THE SECOND MONTH IN A ROW...THE WATER LEVEL ON LAKES MICHIGAN/
HURON REMAINED NEARLY STEADY IN NOVEMBER. BUT SINCE THE NORMAL WATER
LEVEL FALLS A FEW INCHES FROM OCTOBER TO NOVEMBER...THESE LAKES ON
11/30 WERE BETWEEN 14 AND 15 INCHES OF THE LONG-TERM AVERAGE AND 12
TO 13 INCHES HIGHER THAN AT THE END OF NOVEMBER 2012. WATER LEVELS
ON LAKE SUPERIOR FELL SLOWLY THROUGH THE MONTH...REMAINING ABOUT
3 TO 4 INCHES BELOW THE LONG TERM AVERAGE ON 11/30.

                      NOVEMBER CLIMATE HIGHLIGHTS

HIGHEST REPORTED TEMPERATURE...55 AT NUMEROUS LOCATIONS ON 11/5...
                                11/16 AND 11/17

LOWEST REPORTED TEMPERATURE...-9 AT STAMBAUGH IN IRON COUNTY ON 11/29

HIGHEST AVERAGE TEMPERATURE...34.2 DEGREES AT HARVEY IN MARQUETTE
                               COUNTY

LOWEST AVERAGE TEMPERATURE...25.8 DEGREES AT HERMAN IN BARAGA COUNTY

LOWEST MONTHLY PRECIPITATION...2.42 INCHES AT STAMBAUGH

HIGHEST MONTHLY SNOWFALL...40.4 INCHES AT HERMAN

GREATEST SNOW DEPTH...13 INCHES AT HERMAN ON 11/29

A VERY CHANGEABLE WEATHER PATTERN DOMINATED THE GREAT LAKES DURING
THE FIRST THREE WEEKS OF NOVEMBER AS A RELATIVELY ZONAL UPPER FLOW
ALLOWED A SERIES OF TROUGHS AND RIDGES TO MOVE OVER THE AREA. IN
THIS PROGRESSIVE FLOW REGIME THAT LIMITED THE RESIDENCE TIME OF THE
ACCOMPANYING COLD AND WARM AIRMASSES...MEAN DAILY TEMPERATURES
THROUGH 11/21 AVERAGED 1 TO 2 DEGREES ABOVE NORMAL BECAUSE OF THE
MORE ANOMALOUS WARMTH THAT IMPACTED UPPER MICHIGAN AROUND MID
NOVEMBER UNDER ONE OF THE RIDGES. BUT THE WEATHER PATTERN THE LAST
10 DAYS OF THE MONTH SHIFTED TO ONE DOMINATED BY A DEEP TROUGH OVER
CENTRAL AND EASTERN NORTH AMERICA DOWNSTREAM OF A RIDGE OVER THE
WEST. SINCE MEAN DAILY TEMPERATURES DURING THIS PERIOD RAN AS MUCH
AS 15 DEGREES BELOW AVERAGE...THE MONTHLY AVERAGE ENDED UP RUNNING A
DEGREE OR TWO BELOW THE NOVEMBER NORMAL. THE MONTHLY MEAN
TEMPERATURE BETWEEN ABOUT 26 AND 34 DEGREES WAS 13 TO 16 DEGREES
LOWER THAN OBSERVED IN OCTOBER.

THE WARMEST DAYS IN NOVEMBER RELATIVE TO NORMAL WERE ON 11/16 AND
11/17...WHEN MEAN DAILY TEMPERATURES RAN 10 TO 15 DEGREES ABOVE
AVERAGE. THE THERMOMETER PEAKED IN THE 50 TO 55 RANGE AT MANY
LOCATIONS ON THESE DAYS. THERE WERE NO REPORTS OF TEMPERATURES
REACHING THE 60S IN NOVEMBER 2013. THE MERCURY AVERAGED 10 TO 15
DEGREES BELOW NORMAL ON THE THE COLDEST DAYS...WHICH INCLUDED
11/23...11/24...11/28 AND 11/29. SOME OF THE COLDER INTERIOR
LOCATIONS REPORTED SUB-ZERO MINIMUM TEMPERATURES ON 11/24...11/27
AND 11/29.

A PAIR OF MOISTURE-LADEN LOW PRESSURE SYSTEMS IMPACTED UPPER
MICHIGAN DURING THE FIRST THREE WEEKS OF NOVEMBER WHEN THE MORE
PROGRESSIVE PATTERN WAS THE RULE. ONCE THE PATTERN SHIFTED TO THE
DEEP TROUGH THE LAST 10 DAYS OF THE MONTH AND ARCTIC AIR
DOMINATED...MOST OF THE PRECIPITATION WAS LAKE EFFECT SNOW. SO AREAS
AWAY FROM LAKE SUPERIOR WERE GENERALLY DRY THE END OF THE MONTH.

THE FIRST OF THESE LOW PRESSURE SYSTEMS TOOK SHAPE IN THE CENTRAL
PLAINS ON 11/5...THEN RODE NORTHEASTWARD ALONG A STATIONARY FRONT
AND THROUGH EAST CENTRAL UPPER MICHIGAN ON 11/6. ACCOMPANYING
PRECIPITATION WAS HEAVIEST OVER THE EAST...WHERE AS MUCH AS 1.32
INCHES OF RAIN FELL AT MUNISING. TO THE WEST OF THE LOW TRACK...
TEMPERATURES OVER INTERIOR WESTERN UPPER MICHIGAN WERE COLD ENOUGH
TO CAUSE SNOW TO MIX IN WITH THE RAIN. OVER THE HIGHER TERRAIN OF
THE HURON MOUNTAINS IN BARAGA COUNTY...AS MUCH AS 7.2 INCHES OF WET
SNOW ACCUMULATED AT HERMAN. WATTON REPORTED 6.0 INCHES OF THE WHITE
STUFF.

AS AN UPPER TROUGH DEEPENED IN THE ROCKIES ON 11/16...ANOTHER LOW
PRESSURE CENTER DEVELOPED IN THE CENTRAL PLAINS. THIS LOW TRACKED
NORTHEAST UNDER THE SOUTHWEST FLOW ALOFT BETWEEN THE TROUGH OVER THE
WEST AND A RIDGE ACROSS EASTERN NORTH AMERICA...PASSING OVER WESTERN
UPPER MICHIGAN ON 11/17. SOME HEAVY RAIN...AND EVEN SOME RARE
NOVEMBER THUNDERSTORMS OVER THE EAST HALF...PRECEDED THIS LOW
PRESSURE SYSTEM. AN INCH OR MORE OF RAIN FELL OVER MAINLY NORTH
CENTRAL AND EASTERN UPPER MICHIGAN...WITH AS MUCH AS 2.32 INCHES AT
NEWBERRY. WEST TO NORTHWEST WINDS GUSTED AS HIGH AS 50 MPH FROM LATE
ON 11/17 THROUGH 11/18 ONCE THE RAPIDLY DEEPENING LOW SHIFTED TO THE
NORTHEAST INTO ONTARIO.

                     NOVEMBER WEATHER SUMMARY

MORE TO COME LATER.

                         JANUARY 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
JANUARY 2014.

                        JANUARY CLIMATOLOGY

ALTHOUGH DAYLIGHT BEGINS TO INCREASE THROUGH JANUARY (519 MINUTES OF
POSSIBLE SUNSHINE ON 1/1 TO 576 MINUTES ON 1/31)...TEMPERATURES
CONTINUE THEIR DOWNWARD SLIDE DURING THE MONTH AS ARCTIC AIRMASSES
MAKE FREQUENT VISITS TO UPPER MICHIGAN. IN FACT...JANUARY IS THE
COLDEST MONTH AT ALL REPORTING STATIONS...WITH AVERAGE TEMPERATURES
5 TO 6 DEGREES LOWER THAN IN DECEMBER.

THE COLDEST FIRST MONTH IN RECENT MEMORY WAS JANUARY 1994...WHEN
TEMPERATURES ACROSS ALL OF UPPER MICHIGAN AVERAGED ABOUT 10 DEGREES
BELOW NORMAL AND THE MERCURY NEVER ROSE ABOVE THE FREEZING MARK.
JANUARY 1994 GOES DOWN IN THE RECORD BOOKS AS THE COLDEST EVER AT
THE MARQUETTE NWS (AVERAGE TEMPERATURE 2.8)...IRON MOUNTAIN (3.0)...
THE HOUGHTON COUNTY AIRPORT (4.9)...MANISTIQUE (5.8)...ONTONAGON
(5.8)...AND MUNISING (7.8). NEWBERRY RECORDED ITS SECOND COLDEST
JANUARY IN 1994 (5.3)...AND IRONWOOD ITS FOURTH COLDEST (-0.3).
WATER PIPES FROZE IN A NUMBER OF HOMES THROUGHOUT UPPER MICHIGAN
THAT COLD MONTH. A BRUTAL ARCTIC OUTBREAK IN MID-JANUARY 2005 DROVE
TEMPERATURES AS LOW AS -31 AT CHAMPION IN MARQUETTE COUNTY. AT
IRONWOOD...THE MERCURY REMAINED BELOW ZERO FROM LATE IN THE
AFTERNOON ON 1/13 UNTIL JUST AFTER DAWN ON 1/18 IN 2005...INCLUDING
A HIGH OF 6 BELOW ZERO ON 1/15. BOTH IRONWOOD AND NEWBERRY...WHERE
RECORDS GO BACK TO THE EARLY 1900S...SAW THEIR COLDEST JANUARY IN
1912...WHEN AVERAGE TEMPERATURES WERE A FRIGID -5.3 AND 2.7
RESPECTIVELY. MORE RECENTLY...JANUARY 2009 WAS A TOP TEN COLDEST
FIRST MONTH AT MANY LOCATIONS WITH A PERSISTENT UPPER TROUGH LOCKED
OVER THE GREAT LAKES THROUGH THE MONTH. THE MEAN MONTHLY TEMPERATURE
IN JANUARY 2009 WAS 3 TO 7 DEGREES BELOW NORMAL.

ON THE OTHER SIDE OF THE COIN...JANUARY 2006 IS THE WARMEST FIRST
MONTH ON RECORD AT MOST PLACES ACROSS UPPER MICHIGAN. MONTHLY MEAN
TEMPERATURES AVERAGED AN INCREDIBLE 10 TO 15 DEGREES ABOVE THE
LONG-TERM NORMAL. A STRONG WEST-TO-EAST FLOW ALOFT KEPT ARCTIC AIR
BOTTLED UP WELL NORTH IN CANADA...AND THE DAILY TEMPERATURE ENDED UP
ABOVE THE MEAN ALL 31 DAYS OF THE MONTH AT MOST SITES. THERE WAS
ALMOST A COMPLETE ABSENCE OF SUB-ZERO TEMPERATURES IN JANUARY 2006.
FOR THE FIRST TIME SINCE RECORDS BEGAN IN 1901...THE MERCURY DID NOT
FALL BELOW ZERO IN JANUARY AT IRONWOOD IN 2006. AT IRON MOUNTAIN AND
THE MARQUETTE NWS...2006 JOINS 2002 AS THE ONLY YEAR WHEN THE
THERMOMETER NEVER DIPPED BELOW ZERO IN JANUARY. AT MANY PLACES WEST
OF MUNISING AND ESCANABA...1/27/2006 WAS THE WARMEST OR ONE OF THE
TOP FIVE WARMEST JANUARY DAYS ON RECORD. MAXIMUM TEMPERATURES PEAKED
AT OR ABOVE 50 AT MANY LOCATIONS...INCLUDING THE HOUGHTON COUNTY
AIRPORT. THE PREVIOUS HIGHEST JANUARY TEMPERATURE ON RECORD THERE
HAD BEEN 43. AVERAGE JANUARY TEMPERATURES IN 2002...2001...AND 1990
WERE AMONG THE TOP FIVE HIGHEST ON RECORD AT MANY LOCATIONS.
READINGS DURING THOSE MONTHS AVERAGED 5 TO 10 DEGREES OR MORE ABOVE
NORMAL. EVEN MORE RECENTLY...JANUARY 2012 WAS QUITE WARM. MONTHLY
MEAN TEMPERATURES AVERAGED 4 TO 7 DEGREES ABOVE NORMAL...ENOUGH TO
QUALIFY THAT JANUARY AS ONE OF THE TOP TEN WARMEST FIRST MONTHS ON
RECORD.

JANUARY IS THE SNOWIEST MONTH OF THE YEAR AT MOST LOCATIONS. THE
PASSAGE OF ARCTIC AIR OVER THE TYPICALLY UNFROZEN LAKE SUPERIOR
RESULTS IN CONSIDERABLE LAKE EFFECT SNOW. AS THE COLD AIR PASSES
OVER THE RELATIVELY WARM WATERS OF THE LAKE...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
JANUARY PRECIPITATION IS QUITE A BIT LESS AWAY FROM LAKE SUPERIOR.
FOR INSTANCE...THE HOUGHTON COUNTY AIRPORT PICKS UP 62.8 INCHES OF
SNOW AND 3.71 INCHES OF LIQUID EQUIVALENT PRECIPITATION DURING A
TYPICAL JANUARY. IRON MOUNTAIN RECEIVES ONLY 15.0 INCHES OF SNOW AND
1.25 INCHES OF LIQUID EQUIVALENT PRECIPITATION ON AVERAGE. WHILE
RECORD SNOWS AT INLAND LOCATIONS ARE TYPICALLY AROUND 50 INCHES...
LOCATIONS THAT RECEIVE BOTH LAKE EFFECT AND SYNOPTIC SNOW CAN PICK
UP 100 INCHES OF THE WHITE STUFF. DURING THE COLD JANUARY OF 2004...
A LOCATION JUST SOUTHWEST OF ONTONAGON WAS BURIED UNDER 121 INCHES
OF THE WHITE STUFF. TWO HEART IN LUCE COUNTY LOGGED 115 INCHES...AND
BOTH PAINESDALE IN HOUGHTON COUNTY AND PHOENIX IN KEWEENAW COUNTY
REPORTED 112 INCHES. SNOWFALL IN JANUARY 1997 WAS ALSO HEAVY...106.3
INCHES FELL AT THE HOUGHTON COUNTY AIRPORT...100.7 INCHES AT
IRONWOOD...91.7 INCHES AT THE MARQUETTE NWS...AND 88.7 INCHES AT
MUNISING.

DURING DRY AND/OR WARM YEARS...MONTHLY SNOWFALL MAY NOT EXCEED 12
INCHES AT MANY LOCATIONS. IRON MOUNTAIN PICKED UP ONLY 2.3 INCHES OF
SNOW IN JANUARY 1961...EVEN THOUGH THE MONTHLY TEMPERATURE WAS NEAR
NORMAL. AN ACTIVE STORM TRACK THAT YEAR TOO FAR TO THE SOUTH LEFT
MUCH OF UPPER MICHIGAN AWAY FROM LAKE SUPERIOR HIGH AND DRY (TOTAL
LIQUID EQUIVALENT PRECIPITATION AT IRON MOUNTAIN WAS ONLY 0.12
INCHES). DURING A RELATIVELY DRY AND MILD JANUARY 1973 WHEN THERE
WERE FEW ARCTIC INVASIONS...THE MARQUETTE NWS RECORDED ONLY 12.0
INCHES OF SNOW. THE RECORD LOW JANUARY SNOWFALL AT THE HOUGHTON
COUNTY AIRPORT IS 27.7 INCHES (1968).
