                      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 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 SNOW 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

A LARGE...SPRAWLING AREA OF HIGH PRESSURE CENTERED NEAR JAMES BAY
BROUGHT A PERIOD OF COOL...GENERALLY DRY WEATHER TO UPPER MICHIGAN
THE FIRST FIVE DAYS OF OCTOBER. SKIES WERE MOSTLY CLEAR ON 10/1 AND
10/2. WITH LIGHT WINDS...TEMPERATURES EARLY ON 10/1 AND 10/2 DROPPED
INTO THE 20S AT MANY PLACES AWAY FROM THE MODERATING INFLUENCE OF
THE GREAT LAKES AND EVEN AS LOW AS 19 NEAR COVINGTON IN BARAGA
COUNTY AROUND DAYBREAK ON 10/2. THERE WERE MORE CLOUDS ON 10/3
THROUGH 10/5 AND EVEN SOME FOG AND DRIZZLE OVER THE SOUTH CENTRAL
EARLY ON 10/5. ALTHOUGH THESE CLOUDS LIMITED THE FALL OF THE MERCURY
AT NIGHT...READINGS DURING THE DAY WERE COOLER. MEAN DAILY
TEMPERATURES ON 10/5 THROUGH 10/5 RAN ABOUT 5 DEGREES BELOW NORMAL.

A SOUTHWEST FLOW AHEAD OF AN APPROACHING COLD FRONT DREW WARMER AIR
INTO THE UPPER LAKES ON 10/6. DESPITE A GOOD DEAL OF CLOUD COVER...
TEMPERATURES ON 10/6 ENDED UP AROUND 10 DEGREES ABOVE NORMAL AND
FEATURED SOME MAXIMUMS IN THE LOW 70S OVER THE SOUTH CENTRAL...
INCLUDING 71 AT STONINGTON IN DELTA COUNTY. THE COLD FRONT PASSED
DURING THE NIGHT ON 10/6-10/7...BUT THE OVERALL AIRMASS WAS TOO DRY
TO ALLOW FOR ANYTHING MORE THAN SOME CLOUDS AND A FEW SPRINKLES.
COOLER WEATHER THEN WAS THE RULE ON 10/7 IN THE NORTH FLOW AHEAD OF
HIGH PRESSURE DRIFTING EAST THROUGH MINNESOTA. DESPITE INCREASING
SUNSHINE DURING THE AFTERNOON...MEAN DAILY TEMPERATURES ON 10/7 FELL
TO NEAR 5 DEGREES BELOW NORMAL.

AFTER A MAINLY CLEAR EVENING ON 10/7...CLOUDS AND SOME RAIN MOVED
INTO UPPER MICHIGAN FROM THE WEST DURING THE EARLY MORNING HOURS ON
10/8 AHEAD OF LOW PRESSURE TRACKING ACROSS THE NORTHERN PLAINS. THIS
AREA OF RAIN THEN DIMINISHED WEST-TO-EAST BY LATE IN THE DAY AS THE
LOW TRACKED TO THE EAST OF UPPER MICHIGAN. LINGERING LIGHT SHOWERS
AND DRIZZLE DID CONTINUE INTO THE NIGHT ON 10/8-10/9...MAINLY OVER
THE HIGHER TERRAIN NEAR LAKE SUPERIOR IN THE LOW LEVEL NORTH WIND
BETWEEN THE DEPARTING LOW AND TRAILING HIGH PRESSURE DRIFTING EAST
INTO MINNESOTA. TOTAL RAINFALL DURING THIS EVENT ENDED UP BETWEEN
0.15 AND 0.60 INCH AT MOST LOCATIONS. THE INCOMING HIGH PRESSURE
RIDGE DELIVERED A DRY DAY ON 10/9. THE THERMOMETER AVERAGED AROUND 5
DEGREES BELOW AVERAGE ON 10/8...THEN READINGS RECOVERED TO NEAR
NORMAL ON 10/9.

A STRONG SOUTHWEST FLOW...WITH WIND GUSTS AS HIGH AS 30 TO 35 MPH
ON 10/10...ON THE WESTERN FLANK OF THE HIGH PRESSURE DRIFTING TOWARD
THE MID ATLANTIC STATES ADVECTED MUCH WARMER AIR INTO THE UPPER
LAKES THROUGH 10/11. ALTHOUGH THERE WERE QUITE A BIT OF HIGH CLOUDS
ON 10/10...THE DAY ON 10/11 FEATURED LOTS OF SUNSHINE. THE STEADY
WINDS AND HIGH CLOUDS LIMITED THE FALL OF TEMPERATURE DURING THE
NIGHT ON 10/10-10/11...WITH READINGS FALLING NO LOWER THAN ABOUT 60
AT A FEW PLACES...INCLUDING 62 AT BIG BAY IN MARQUETTE COUNTY. THE
WARM EARLY MORNING AND ABUNDANT SUNSHINE SET THE STAGE FOR SOME
RECORD WARMTH ON 10/11...WHEN TEMPERATURES TOPPED OUT IN THE 80S AT
MANY PLACES AWAY FROM LAKE MODERATION. THE THERMOMETER EVEN READ AS
HIGH AS A SUMMER-LIKE 91 AT PELKIE NEAR THE BARAGA/HOUGHTON COUNTY
LINE AND 90 AT BARAGA DURING THE AFTERNOON ON 10/11. A COLD FRONT
ASSOCIATED WITH LOW PRESSURE IN ONTARIO PUSHED ACROSS UPPER MICHIGAN
ON 10/12. BEFORE THE FRONT ARRIVED...MORNING LOWS ON 10/12 OVER THE
EAST STAYED AS HIGH AS 61 AT GRAND MARAIS IN ALGER COUNTY AND
FAIRPORT ON THE GARDEN PENINSULA IN DELTA COUNTY. ALTHOUGH COOLER
AIR AND MORE CLOUDS FOLLOWED ON 10/12...DAYTIME HIGHS ON 10/12
REMAINED ABOVE NORMAL. MEAN DAILY TEMPERATURES DURING THIS WARM
PERIOD WERE NEAR 5 DEGREES ABOVE NORMAL ON 10/10...15 TO 25 DEGREES
ABOVE AVERAGE ON 10/11 AND THEN 10 TO 15 DEGREES ABOVE NORMAL ON
10/12.

AS AN UPPER TROUGH DEEPENED OVER EASTERN NORTH AMERICA...A STRONGER
SECOND COLD FRONT SWEPT THROUGH THE UPPER GREAT LAKES DURING THE
NIGHT ON 10/12-10/13...ACCOMPANIED BY PLENTY OF CLOUDS AND SOME
SHOWERS. NORTHWEST WINDS GUSTING UP TO 40 MPH DROVE MORE SEASONABLY
CHILLY AIR INTO UPPER MICHIGAN. THE STRONG WINDS AND SHOWERS SLOWLY
DIMINISHED ON 10/13 WITH THE CLOSER APPROACH OF HIGH PRESSURE IN
MINNESOTA...BUT SKIES REMAINED MOSTLY CLOUDY. TOTAL RAINFALL THROUGH
10/13 RANGED FROM ABOUT 0.10 INCH OVER THE SOUTH CENTRAL TO NEARLY
0.50 INCH AT A FEW PLACES NEAR LAKE SUPERIOR EAST OF MARQUETTE. THE
WEATHER ON 10/14 WAS CLEAR TO PARTLY CLOUDY AS THE HIGH PRESSURE
RIDGE CROSSED UPPER MICHIGAN. THE THERMOMETER AVERAGED NEAR NORMAL
READINGS ON 10/13 AND 10/14.

A STRONGER DISTURBANCE EMBEDDED IN THE DEEP EASTERN NORTH AMERICA
TROUGH AND ITS ATTENDANT COLD FRONT PASSED THROUGH THE UPPER GREAT
LAKES ON 10/15. SCATTERED SHOWERS...AND EVEN A FEW THUNDERSTORMS...
THAT DROPPED SOME SMALL HAIL AT SPOTS ACCOMPANIED THIS DISTURBANCE.
THERE WERE EVEN TWO WATERSPOUTS OBSERVED ON LAKE SUPERIOR BETWEEN
MARQUETTE AND MUNISING. THE COLDEST AIRMASS OF THE SEASON THAN
FOLLOWED INTO THE UPPER LAKES ON 10/16 AND 10/17 ON THE HEELS OF
NORTHWEST WINDS GUSTING UP TO 30 TO 35 MPH. THERE WERE SCATTERED TO
NUMEROUS RAIN AND SNOW SHOWERS...MAINLY IN THE AREAS DOWNSTREAM OF
LAKE SUPERIOR EAST OF MARQUETTE. MANY PLACES SAW THEIR FIRST SNOW
ACCUMULATION OF THE SEASON DURING THE NIGHT ON 10/16-10/17...WHEN AS
MUCH AS 3 TO 6 INCHES OF SNOW FELL IN EASTERN MARQUETTE AND ALGER
COUNTIES AWAY FROM THE WARMING INFLUENCE OF THE LAKE. SUNDELL IN
WESTERN ALGER COUNTY MEASURED THE HEAVIEST HALF FOOT SNOW
ACCUMULATION. SKY COVER ON 10/16 AND 10/17 WAS PARTLY TO MOSTLY
CLOUDY...WITH THE MORE PERSISTENT CLOUDS NEAR LAKE SUPERIOR.

AS HIGH PRESSURE IN THE PLAINS EDGED TO THE EAST...LINGERING
LAKE EFFECT CLOUDS GAVE WAY TO MOSTLY CLEAR SKIES WEST-TO-EAST
DURING THE MORNING ON 10/18. AT WAKEFIELD IN GOGEBIC COUNTY AND
STAMBAUGH IN IRON COUNTY...THE THERMOMETER DIPPED AS LOW AS 19 AT
SUNRISE ON 10/18. HIGH CLOUDS AND SOUTHWEST WINDS GUSTING TO 30 TO
35 MPH ON 10/19 PRECEDED A COLD FRONTAL PASSAGE DURING THE NIGHT ON
10/19-10/20...BUT THE AIRMASS OVER THE UPPER LAKES WAS TOO DRY FOR
ANY PRECIPITATION. HIGH PRESSURE BUILDING INTO ONTARIO BEHIND THIS
COLD FRONT BROUGHT PARTLY CLOUDY AND COOLER CONDITIONS FOR 10/20.
MEAN DAILY TEMPERATURES AROUND 5 DEGREES BELOW NORMAL ON 10/18 ROSE
TO NEAR 10 DEGREES ABOVE AVERAGE ON 10/19 WITHIN THE SOUTHWEST FLOW
AHEAD OF THE COLD FRONT BEFORE READINGS FELL OFF TO NEAR NORMAL ON
10/20 AS THE SEASONABLY COOL TRAILING AIRMASS MOVED OVERHEAD.

MORE CLOUDS AND SOME SHOWERS ARRIVED MAINLY OVER THE SOUTHEAST HALF
OF UPPER MICHIGAN DURING THE NIGHT ON 10/20-10/21 AHEAD OF A STRONG
DISTURBANCE AND ASSOCIATED LOW PRESSURE SYSTEM THAT MOVED THROUGH
ONTARIO ON 10/21. FOLLOWING THE PASSAGE OF THE COLD FRONT ASSOCIATED
WITH THIS LOW...NORTHWEST WINDS GUSTED AS HIGH AS 40 TO 45 MPH NEAR
LAKE SUPERIOR DURING THE NIGHT ON 10/21-10/22. ALTHOUGH LOTS OF
CLOUDS LINGERED DURING THE NIGHT AND THERE WERE EVEN A FEW SPRINKLES
MAINLY ACROSS THE HIGHER TERRAIN NEAR LAKE SUPERIOR...DRYING BEHIND
THE FRONT CAUSED PRECIPITATION TO END AT MOST PLACES. RAIN TOTALS
DURING THIS EVENT RANGED FROM LESS THAN A TENTH OF AN INCH OVER THE
NORTHWEST TO UP TO 0.25 TO 0.50 INCH OVER THE SOUTH CENTRAL AND
EAST. SENEY IN SCHOOLCRAFT COUNTY REPORTED THE HEAVIEST RAIN WITH
0.92 INCH. A SECOND COLD FRONT PASSED DURING THE DAY ON 10/22...BUT
THE ONLY IMPACT WAS A GOOD DEAL OF CLOUD COVER. THE DAY ON 10/21
AHEAD OF THE COLD FRONT AVERAGED 5 TO 10 DEGREES WARMER THAN
NORMAL...BUT THE MEAN DAILY TEMPERATURE ON 10/22 FELL OFF TO NEAR 5
DEGREES BELOW NORMAL AFTER COOL AIR FOLLOWED THE FRONTAL PASSAGES.

THICKENING CLOUDS ON 10/23 HERALDED THE APPROACH OF A DEEP LOW
PRESSURE SYSTEM LIFTING NORTHEAST OUT OF THE PLAINS TOWARD THE UPPER
LAKES. SOME SHOWERS WELL AHEAD OF THIS LOW ARRIVED OVER THE WEST
LATE ON 10/23 AND THEN OVERSPREAD THE REST OF THE U.P. DURING THE
NIGHT ON 10/23-10/24 AS FOG ALSO DEVELOPED. A MORE WIDESPREAD HEAVY
RAIN FELL ON 10/24 AS THE LOW MOVED CLOSER. ONCE THIS CYCLONE MOVED
OFF TO THE NORTHEAST LATER IN THE DAY...THE RAIN GAVE WAY TO SOME
PARTIAL CLEARING AS NORTHWEST WINDS GUSTING AS HIGH AS 40 TO 45 MPH
NEAR LAKE SUPERIOR DREW SOME DRIER AIR OVERHEAD. MOST PLACES PICKED
UP 0.50 TO 1.00 INCH OF RAIN ON 10/23 AND 10/24. WATERSMEET IN
GOGEBIC COUNTY LED REPORTING STATIONS WITH 1.03 INCHES. A TRAILING
LOW PRESSURE TROUGH CAUSED MORE CLOUDS AND SCATTERED SHOWERS LATE AT
NIGHT ON 10/24-10/25 AND INTO THE AFTERNOON ON 10/25...BUT
PRECIPITATION AMOUNTS WERE GENERALLY UNDER 0.10 INCH. NEAR NORMAL
MEAN DAILY TEMPERATURES ON 10/23 ROSE TO ABOUT 5 DEGREES ABOVE
AVERAGE ON 10/24. THE THERMOMETER THEN DIPPED TO NEARLY 5 DEGREES
BELOW NORMAL ON 10/25 AS SOME COLDER AIR FOLLOWED THE EXITING LOW AND
SECONDARY TROUGH.

AFTER SOME EVENING CLEARING ASSOCIATED WITH A PASSING HIGH PRESSURE
RIDGE...MORE CLOUDS ROLLED BACK INTO THE AREA DURING THE EARLY
MORNING ON 10/26 AS A LOW PRESSURE SYSTEM TRACKED EAST ALONG A
STATIONARY FRONT STRETCHING FROM MINNESOTA THROUGH WISCONSIN INTO
NORTHERN LOWER MICHIGAN. SHOWERS ASSOCIATED WITH THIS LOW TRACKING
TO THE EAST IMPACTED MAINLY THE SOUTH HALF OF UPPER MICHIGAN THROUGH
THE DAY ON 10/26. AFTER THE LOW MOVED FARTHER EAST...LINGERING RAIN
ENDED BY THE EARLY MORNING HOURS ON 10/27. BUT SKIES REMAINED MOSTLY
CLOUDY...AND AREAS OF FOG DEVELOPED. RAINFALL ON 10/26 VARIED FROM
NONE OVER THE KEWEENAW TO AROUND 0.25 INCH AT A NUMBER OF PLACES
ACROSS THE SOUTHERN TIER OF UPPER MICHIGAN. AREAS OF MORNING FOG ON
10/27 THEN GAVE WAY TO A PARTLY TO MOSTLY SUNNY AFTERNOON AS AN EAST
FLOW AROUND HIGH PRESSURE CENTERED NEAR JAMES BAY PUSHED SOME DRIER
AIR INTO THE UPPER GREAT LAKES. MEAN DAILY TEMPERATURES NEAR 5
DEGREES BELOW AVERAGE ON 10/26 REBOUNDED TO ABOUT 5 DEGREES ABOVE
NORMAL ON 10/27.

AFTER THE BRIEF PERIOD OF DRY WEATHER ON 10/27...MORE CLOUDS AND
SOME RAIN ARRIVED FROM THE SOUTHWEST DURING THE NIGHT ON 10/27-10/28
AS A MOIST LOW PRESSURE SYSTEM...WHICH WAS THE REMNANT OF THE ONCE
POWERFUL HURRICANE PATRICIA THAT HAD COME ASHORE IN WESTERN MEXICO
ON 10/23...MOVED NORTH INTO THE UPPER MIDWEST. PERIODS OF RAIN AND
SOME FOG WERE THE RULE ON 10/28 AS THE LOW TRACKED ACROSS THE U.P.
ALTHOUGH THE RAIN TENDED TO DIMINISH LATER ON 10/28 AFTER THE LOW
ADVANCED INTO ONTARIO...A LOW PRESSURE TROUGH SWINGING TO THE EAST
ON THE SOUTHERN FLANK OF THE LOW IN CANADA KEPT SOME SHOWERS GOING
ESPECIALLY OVER THE NORTHWEST HALF THROUGH THE DAY ON 10/29. THE
ARRIVAL OF SOME COLDER AIR IN THE GUSTY WEST TO NORTHWEST FLOW ON
THE SOUTHERN FLANK OF THE DEPARTING LOW CAUSED THE RAIN TO MIX WITH
SOME SNOW. IN THIS CASE...THE WARMING INFLUENCE OF LAKE SUPERIOR
SLOWED DOWN THE COOLING OVER THE NORTH...SO THE SNOW ACCUMULATED
ONLY OVER THE SOUTH CENTRAL AWAY FROM THAT LAKE MODERATION DURING
THE MORNING ON 10/29. GRAND MARAIS IN ALGER COUNTY REPORTED THE
STRONGEST WIND GUST OF 47 MPH ON 10/29. BY THE TIME HIGH PRESSURE
AND DRIER AIR ARRIVED EARLY ON 10/30 AFTER THE LOW HAD DRIFTED
FARTHER NORTH 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. UP TO 2 INCHES OF WET SNOW
ACCUMULATED NEAR GLADSTONE AND BRAMPTON IN DELTA COUNTY EARLY ON
10/29. THE MERCURY ENDED UP 5 TO 10 DEGREES ABOVE NORMAL ON 10/28.
READINGS ON 10/29 AVERAGED NEAR NORMAL OVER THE NORTH TO 5 DEGREES
BELOW NORMAL OVER THE SOUTH.

THERE WAS ANOTHER BRIEF PERIOD OF DRIER WEATHER ON 10/30 AS A
TRAILING HIGH PRESSURE RIDGE MOVED FROM THE GREAT LAKES INTO THE
NORTHEAST STATES. THE SOUTHWEST FLOW ON ITS WESTERN FLANK DREW MORE
MOISTURE INTO THE AREA...SO SKIES WERE MOSTLY CLOUDY. THIS
PERSISTENT SOUTHWEST FLOW BETWEEN THE HIGH AND ANOTHER LOW PRESSURE
SYSTEM MOVING EAST THROUGH THE PLAINS NEAR THE CANADIAN BORDER
ADVECTED DEEPER MOISTURE OVER UPPER MICHIGAN...RESULTING IN MORE
RAIN BY THE EARLY MORNING ON 10/31. THESE PERIODS OF RAIN CONTINUED
THROUGH HALLOWEEN...BUT BEGAN TO DIMINISH BY THE EVENING OVER THE
WEST. RAINFALL AMOUNTS OF 0.50 TO 0.75 INCH WERE COMMON ON 10/31...
MAKING FOR A WET TRICK-OR-TREATING EXPERIENCE ESPECIALLY OVER THE
EAST HALF...WHERE THE RAIN DID NOT END UNTIL NEAR MIDNIGHT. MEAN
DAILY TEMPERATURES WERE NEAR 5 DEGREES BELOW NORMAL ON 10/30 AND
THEN 5 DEGREES ABOVE AVERAGE ON 10/31.

                          DECEMBER FORECAST

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

                        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
11:48 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. 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.

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.

                OUTLOOK FOR WINTER INTO EARLY SPRING

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING A GREATER THAN
CLIMATOLOGICAL CHANCE OF AN ABOVE NORMAL 3-MONTH AVERAGE TEMPERATURE
