                      OCTOBER CLIMATE HIGHLIGHTS

HIGHEST REPORTED TEMPERATURE...91 AT PELKIE IN BARAGA COUNTY ON 10/11

LOWEST REPORTED TEMPERATURE...19 NEAR COVINGTON IN BARAGA COUNTY ON
                              10/2 AND AT WAKEFIELD IN GOGEBIC COUNTY
                              AND STAMBAUGH IN IRON COUNTY ON 10/18

HIGHEST AVERAGE TEMPERATURE...47.7 DEGREES AT COPPER HARBOR

LOWEST AVERAGE TEMPERATURE...42.2 DEGREES AT CLARKSBURG IN MARQUETTE
                              COUNTY

HIGHEST MONTHLY PRECIPITATION...4.25 INCHES AT CHATHAM IN ALGER
                                 COUNTY

LOWEST MONTHLY PRECIPITATION...2.01 INCHES AT COPPER HARBOR

HIGHEST MONTHLY SNOWFALL...5.3 INCHES AT CHATHAM

AFTER AN UPPER RIDGE DOMINATED IN SEPTEMBER...THE WEATHER PATTERN
TURNED A BIT MORE CHANGEABLE IN OCTOBER. BUT SINCE AN UPPER RIDGE
PREVAILED MORE OF THE TIME THAN NOT...THE MONTH TURNED OUT WARMER
AND DRIER THAN NORMAL OVERALL. THE FIRST THREE WEEKS OF OCTOBER WERE
PARTICULARLY DRY WITH A NEAR ABSENCE OF MOISTURE-LADEN LOW PRESSURE
SYSTEMS. AFTER THE WARM AND DRY WEATHER OBSERVED IN SEPTEMBER...THE
U.S. DROUGHT MONITOR INDICATED A MODERATE DROUGHT DEVELOPED BY MID-
OCTOBER ACROSS PORTIONS OF THE NORTH CENTRAL U.P. THE WEATHER
PATTERN TURNED MORE ACTIVE THE LAST TEN DAYS OF THE MONTH...
ALLOWING SOME DEEPER LOW PRESSURE SYSTEMS TO BRING WIDESPREAD RAIN
TO THE AREA. MONTHLY PRECIPITATION RANGED FROM ABOUT 2 TO 3.5 INCHES
AT MOST PLACES...TOTALS THAT AVERAGED NOT FAR FROM 75 PERCENT OF
NORMAL.

THE MEAN OCTOBER TEMPERATURE ACROSS UPPER MICHIGAN ENDED UP BETWEEN
ABOUT 42 TO 48 DEGREES...READINGS THAT RANGED FROM NEAR NORMAL TO
ABOUT 2 DEGREES ABOVE AVERAGE AND WHICH MADE OCTOBER 16 TO 19
DEGREES COOLER THAN SEPTEMBER. THE WARMEST WEATHER IN OCTOBER
OCCURRED DURING THE SECOND WEEK...A TIME WHEN THE UPPER RIDGE WAS
STRONGEST. THE TEMPERATURE ANOMALIES WERE MOST PRONOUNCED ON 10/11
AND 10/12...DAYS WHEN THE THERMOMETER READ ABOUT 25 AND 10 TO 15
DEGREES ABOVE NORMAL RESPECTIVELY. MANY PLACES AWAY FROM THE COOLING
INFLUENCE OF LAKE MICHIGAN SAW THE MERCURY SURGE INTO THE 80S ON
10/11...READINGS WHICH IN SOME CASES ESTABLISHED NEW DAILY RECORD
MAXIMUM TEMPERATURES. PELKIE IN BARAGA COUNTY EVEN SAW TEMPERATURES
CLIMB ALL THE WAY TO A SUMMER-LIKE 91...WHICH ENDED UP AS THE
HIGHEST REPORTED TEMPERATURE OF THE MONTH IN UPPER MICHIGAN. THE 86-
DEGREE HIGH REPORTED AT THE HOUGHTON COUNTY AIRPORT SET NOT ONLY A
DAILY RECORD HIGH TEMPERATURE BUT TIED THE PREVIOUS RECORD WARMEST
TEMPERATURE FOR THE ENTIRE MONTH OF OCTOBER. THERE WERE NO OTHER
REPORTS OF 80-DEGREE TEMPERATURES ON ANY OTHER DAY IN OCTOBER.

THE COOLEST WEATHER FOLLOWED JUST A COUPLE OF DAYS LATER AFTER A
DEEP UPPER TROUGH HAD DISPLACED THE RIDGE RESPONSIBLE FOR THE RECENT
WARMTH. A STRONG COLD FRONT PLOWED THROUGH THE UPPER LAKES ON
10/15...WHEN SHOWERS THAT FORMED IN ITS WAKE OVER LAKE SUPERIOR
GENERATED TWO WATERSPOUTS BETWEEN MARQUETTE AND MUNISING. MEAN DAILY
TEMPERATURES ON 10/16 AND 10/17 FELL TO 10 TO 15 DEGREES BELOW
NORMAL ON 10/16 AND 10/17 AS COLDER AIR SURGED INTO THE AREA. HIGH
TEMPERATURES ON THESE DAYS HELD IN THE 30S AT MANY PLACES IN THE
HIGHER TERRAIN OF THE INTERIOR. THIS INFLUX OF CHILLY CANADIAN AIR
OVER THE RELATIVELY WARM LAKE WATERS RESULTED IN PLENTY OF CLOUDS
AND LAKE EFFECT RAIN AND SHOWERS...WHICH WERE MOST NUMEROUS NEAR
LAKE SUPERIOR...FROM 10/15 THROUGH 10/17. THE FIRST ACCUMULATING
SNOW OF THE SEASON FELL AT MANY PLACES IN THE NORTHWEST WIND SNOW
BELTS EAST OF MARQUETTE IN THE EARLY MORNING ON 10/17. SUNDELL IN
WESTERN ALGER COUNTY PICKED UP AS MUCH AS 6 INCHES OF THE WHITE
STUFF. LOW TEMPERATURES FELL INTO THE TEENS AT SOME OF THE COLDER
INTERIOR LOCATIONS ON 10/2 AND 10/18.

THE FIRST WIDESPREAD MODERATE TO HEAVY RAIN EVENT OF THE MONTH
OCCURRED ON 10/23 INTO 10/24 IN ADVANCE OF LOW PRESSURE LIFTING
NORTHEAST OUT OF THE PLAINS TOWARD THE UPPER LAKES. MOST PLACES
PICKED UP 0.50 TO 1.00 INCH OF RAIN. AFTER THE LOW EXITED TO THE
NORTHEAST...THE RAIN DIMINISHED...BUT NORTHWEST WINDS GUSTED AS HIGH
AS 40 TO 45 MPH NEAR LAKE SUPERIOR ON 10/24 IN ITS WAKE.

THE APPROACH OF ANOTHER LOW PRESSURE SYSTEM...WHICH WERE THE REMAINS
OF HURRICANE PATRICIA THAT HAD STRUCK MEXICO SEVERAL DAYS BEFORE...
FROM THE SOUTHWEST BROUGHT ANOTHER WIDESPREAD PRECIPITATION EVENT TO
UPPER MICHIGAN ON 10/28 AND 10/29. BY THE TIME DRIER AIR ARRIVED
EARLY ON 10/30 AFTER THE LOW HAD DRIFTED INTO ONTARIO...A GENERAL
0.50 TO 1.50 INCHES OF PRECIPITATION HAD FALLEN ACROSS THE U.P.
MOHAWK IN KEWEENAW COUNTY REPORTED THE MOST WITH 1.78 INCHES. SINCE
THIS LOW PRESSURE WAS SO INTENSE...WEST TO NORTHWEST WINDS GUSTED AS
HIGH AS 47 MPH AT GRAND MARAIS IN ALGER COUNTY ON 10/29 AFTER THE
LOW HAD SHIFTED INTO ONTARIO. COLD AIR WRAPPED WELL AROUND THE
DEPARTING STORM SYSTEM...CHANGING THE RAIN TO SNOW OVER THE SOUTH
CENTRAL. UP TO 2 INCHES OF WET SNOW ACCUMULATED NEAR GLADSTONE AND
BRAMPTON IN DELTA COUNTY EARLY ON 10/29.

THE INTERACTION BETWEEN AN APPROACHING DISTURBANCE AND A SOUTHWEST
FLOW OF MOIST AIR RESULTED IN ANOTHER WIDESPREAD RAIN EVENT ON
10/31. RAINFALL AMOUNTS OF 0.50 TO 0.75 INCH WERE COMMON TO END THE
MONTH...MAKING FOR A WET TRICK-OR-TREATING EXPERIENCE OVER THE EAST
HALF...WHERE THE RAIN DID NOT END UNTIL NEAR MIDNIGHT.

                         OCTOBER WEATHER SUMMARY

MORE TO COME LATER.

                            NOVEMBER FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING A GREATER THAN
CLIMATOLOGICAL CHANCE OF AN ABOVE NORMAL MONTHLY MEAN TEMPERATURE
BUT EQUAL CHANCES OF ABOVE AND BELOW NORMAL PRECIPITATION OVER ALL
OF UPPER MICHIGAN IN NOVEMBER 2015.

                           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 2014
GOES DOWN IN THE RECORD BOOKS AS ONE OF THE TOP FIVE COLDEST
ELEVENTH MONTHS ON RECORD AT MOST PLACES IN UPPER MICHIGAN. THE MEAN
MONTHLY TEMPERATURE DURING THAT CHILLY NOVEMBER ENDED UP 5 TO 9
DEGREES BELOW NORMAL AND MORE TYPICAL OF DECEMBER DUE TO A
PERSISTENT UPPER TROUGH THAT PREVAILED MUCH OF THE TIME OVER CENTRAL
AND EASTERN NORTH AMERICA AND WHICH ALLOWED A NEARLY CONTINUOUS
INFLUX OF CHILLY CANADIAN AIR INTO THE UPPER LAKES. NOVEMBERS IN
1995...1976...AND 1959 WERE ALSO QUITE CHILLY AND AMONG THE TOP FIVE
COLDEST AT MOST LOCATIONS. 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 BECOMES A GREATER THREAT DURING NOVEMBER AS DEEP
LOW PRESSURE SYSTEMS ENCOUNTER COLDER AIR IN PLACE IN THE UPPER
LAKES. AS THE MORE FREQUENT COLD AIR INVASIONS PASS OVER THE
RELATIVELY WARM WATERS OF LAKE SUPERIOR AND THE ARCTIC AIRMASSES
DESTABILIZE...LAKE EFFECT SNOWS ALSO BECOME MORE LIKELY. THESE SNOW
SHOWERS 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. AVERAGE NOVEMBER SNOW RANGES FROM
NEARLY 24 INCHES AT HOUGHTON AND IRONWOOD TO AROUND 6 INCHES OR LESS
FROM IRON MOUNTAIN TO MANISTIQUE.

DURING THE COLD NOVEMBER IN 2014...AN INTENSE VETERANS DAY LOW
PRESSURE SYSTEM BROUGHT RECORD SNOWFALL TO MANY PLACES IN UPPER
MICHIGAN ON 11/10 INTO 11/12. INCLUDING THE HEAVY LAKE EFFECT SNOWS
THAT FELL ON 11/12 INTO 11/14 IN THE COLD CANADIAN AIRFLOW THAT
FOLLOWED...STORM TOTAL SNOWFALL REACHED AS MUCH AS 36 TO 45 INCHES
OVER THE HIGHER TERRAIN OF THE HURON MOUNTAINS. NORTH WIND GUSTS AS
HIGH AS 45 MPH ALSO CAUSED CONSIDERABLE BLOWING SNOW AND BLIZZARD
CONDITIONS IN EXPOSED AREAS...MAINLY ON 11/11. NEARLY A RECORD 90
INCHES OF SNOW ACCUMULATED DURING THE ENTIRE MONTH OF NOVEMBER 2014
AT SOME PLACES OVER THE HIGHER TERRAIN OF WESTERN UPPER MICHIGAN.

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.

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 A GREATER THAN
CLIMATOLOGICAL CHANCE OF AN ABOVE NORMAL 3-MONTH AVERAGE TEMPERATURE
AND BELOW NORMAL 3-MONTH PRECIPITATION OVER ALL OF UPPER MICHIGAN
IN DECEMBER 2015 THROUGH FEBRUARY 2016. THESE FORECAST TEMPERATURE
AND PRECIPITATION ANOMALIES ARE DUE TO A GROWING EL NINO IN THE
TROPICAL EASTERN PACIFIC OCEAN.
