...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.

                       OCTOBER WEATHER SUMMARY

MORE TO COME LATER.

                          NOVEMBER 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
NOVEMBER 2013.

                        NOVEMBER CLIMATOLOGY

RESIDENTS OF UPPER MICHIGAN FEEL WINTER`S TIGHTENING GRIP MORE AND
MORE OFTEN DURING NOVEMBER AS THE SUN`S WARMING RAYS BECOME
INCREASINGLY FEEBLE. POSSIBLE SUNSHINE DECLINES FROM 605 MINUTES ON
11/1 TO 533 MINUTES ON 11/30. AS A RESULT...THE AVERAGE TEMPERATURE
DURING NOVEMBER IS AS MUCH AS 15 DEGREES LOWER THAN IN OCTOBER.

DESPITE THE INEVITABLE DECLINE TOWARD WINTER...PLEASANTLY MILD
WEATHER OFTEN MAKES AN APPEARANCE DURING THE ELEVENTH MONTH.
NOVEMBER 2001 GOES DOWN IN THE RECORD BOOKS AS THE WARMEST EVER AT
ALL REPORTING STATIONS WITH A MEAN TEMPERATURE 10 OR MORE DEGREES
ABOVE NORMAL. MANY STATIONS REPORTED MORE DAYS WITH A HIGH
TEMPERATURE OVER 50 THAN IN ANY OTHER ELEVENTH MONTH...18 DAYS AT
IRONWOOD AND IRON MOUNTAIN AND 13 DAYS AT THE MARQUETTE NWS. AT THE
MARQUETTE NWS...13 DAILY RECORD HIGH MAXIMUM OR MINIMUM TEMPERATURE
RECORDS WERE EITHER BROKEN OR TIED. NOVEMBER 2009 FEATURED
UNSEASONABLY WARM WEATHER AND A MEAN MONTHLY TEMPERATURE 6 TO 9
DEGREES ABOVE AVERAGE...ENOUGH TO QUALIFY THE MONTH AS THE WARMEST
NOVEMBER ON RECORD AT HOUGHTON AND ONE OF THE TOP THREE WARMEST
THROUGHOUT UPPER MICHIGAN. NOVEMBER 1999 IS ALSO AMONG THE TOP FIVE
WARMEST ON RECORD AT MANY PLACES. BETWEEN 11/8/99 AND 11/10/99...
HIGH TEMPERATURES OVER MUCH OF UPPER MICHIGAN REACHED NEAR OR ABOVE
70. RESIDENTS OF IRON MOUNTAIN ENJOYED A MONTHLY-RECORD-TYING
75-DEGREE AFTERNOON ON 11/9/99. THE 73-DEGREE READING AT THE
MARQUETTE NWS ON 11/9/99 IS THE HIGHEST NOVEMBER TEMPERATURE EVER
RECORDED AT THAT STATION. IRONWOOD REACHED 72 ON THAT DAY...ONLY TWO
DEGREES SHY OF THE MONTHLY RECORD 74. OTHER WARM SPELLS OCCURRED IN
EARLY NOVEMBER 1990...1978 AND 1975. THE RECORD WARMTH THAT
ENVELOPED UPPER MICHIGAN DURING THE FIRST WEEK OF NOVEMBER 1975 AND
SPREAD TO THE EAST COAST DURING THE SECOND WEEK CONTRIBUTED TO THE
INTENSITY OF THE STORM THAT ROARED OVER LAKE SUPERIOR ON 11/10/75
AND SANK THE EDMUND FITZGERALD.

BUT NOVEMBER CAN ALSO FEATURE ALMOST MID WINTER CHILL. NOVEMBER
1995...1976...AND 1959 ARE AMONG THE TOP THREE COLDEST NOVEMBERS AT
MOST LOCATIONS. TEMPERATURES AVERAGED AS MUCH AS 5 TO 8 DEGREES
BELOW NORMAL DURING THESE MONTHS...WITH READINGS MORE TYPICAL OF
DECEMBER. ONE OF THE COLDEST AIRMASSES EVER TO INVADE UPPER MICHIGAN
DURING NOVEMBER IMPACTED THE WESTERN GREAT LAKES BETWEEN 11/28/76
AND 11/30/76. THE LOWEST NOVEMBER TEMPERATURE EVER OBSERVED AT
IRONWOOD (-18)...THE MARQUETTE NWS (-13)...IRON MOUNTAIN (-10)...
NEWBERRY (-10) AND MANISTIQUE (-6) OCCURRED ON ONE OF THOSE THREE
DAYS.

SIGNIFICANT SNOW...ESPECIALLY LAKE EFFECT SNOW...BECOMES A GREATER
THREAT DURING NOVEMBER. AS MORE FREQUENT COLD AIR INVASIONS PASS
OVER THE RELATIVELY WARM WATERS OF LAKE SUPERIOR...THE AIRMASS
BECOMES INCREASINGLY UNSTABLE. THE RESULT IS A GREATER FREQUENCY OF
SNOW SHOWERS...WHICH ARE TYPICALLY HEAVIER AND MORE WIDESPREAD OVER
HIGHER TERRAIN JUST DOWNWIND OF LAKE SUPERIOR. THE AGGREGATE WARMTH
OF ALL THE GREAT LAKES ALSO INFLUENCES THE INTENSITY AND PATH OF
LARGE LOW PRESSURE SYSTEMS APPROACHING THE AREA. IN MOST CASES...
SURFACE LOWS INTENSIFY MORE QUICKLY AND TAKE A PATH FARTHER WEST
THAN THEY WOULD IF THE LAKES WERE ABSENT. THIS DEVIATION IN STORM
PATH IN GENERAL FAVORS HEAVIER SNOW ACROSS WESTERN UPPER MICHIGAN
THAN IN THE EAST. HIGHER TERRAIN AREAS ACROSS THE WEST THAT ALSO ARE
FAVORED FOR LAKE EFFECT SNOW THUS HAVE THE HIGHEST NORMAL NOVEMBER
SNOWFALL...AND LIQUID EQUIVALENT PRECIPITATION. IRONWOOD WAS
SMOTHERED UNDER 78 INCHES OF THE WHITE STUFF IN NOVEMBER 1989. ON
THE OTHER HAND...RECORD LOW SNOW FELL IN NOVEMBER 2009. DURING THAT
MONTH...THE COMBINATION OF UNSEASONABLE WARMTH THAT SHUT OFF THE
LAKE EFFECT SNOW MACHINE AND A DRY FLOW THAT PREVENTED LARGER SCALE
STORM SYSTEMS AND PRECIPITATION FROM MOVING INTO THE UPPER GREAT
LAKES RESULTED IN RECORD LOW SNOWFALL UNDER 1 TO 6 INCHES AT MOST
LOCATIONS. ONLY A TRACE OF SNOW FELL AT MUNISING IN NOVEMBER 2009.
AVERAGE NOVEMBER SNOW RANGES FROM NEARLY 24 INCHES AT HOUGHTON AND
IRONWOOD TO AROUND 6 INCHES OR LESS FROM IRON MOUNTAIN TO
MANISTIQUE.

DESTABILIZATION OF COLD AIR MASSES OVER LAKE SUPERIOR AND RAPIDLY
INTENSIFYING SURFACE LOWS HELP MAKE NOVEMBER ONE OF THE WINDIEST
MONTHS OF THE YEAR...ESPECIALLY NEAR LAKE SUPERIOR. THERE IS TRUTH
IN THE PHRASE...GALES OF NOVEMBER.

                          OUTLOOK FOR WINTER

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING EQUAL CHANCES OF
AN ABOVE AND BELOW NORMAL 3-MONTH MEAN TEMPERATURE AND 3-MONTH
