...GREAT LAKES WATER LEVELS RISE A BIT IN SEPTEMBER...

EVEN THOUGH WATER LEVELS TYPICALLY HOLD STEADY OR FALL SLOWLY IN
SEPTEMBER...ABOVE NORMAL PRECIPITATION ACROSS THE UPPER GREAT LAKES
AND SURROUNDING AREAS THE LAST COUPLE OF MONTHS THAT HAS CONTRIBUTED
TO GREATER RUNOFF AS WELL AS RELATIVELY CHILLY LAKE WATER
TEMPERATURES THAT HAVE LIMITED EVAPORATION CONTRIBUTED TO A SLOW
RISE IN THE LEVELS OF LAKES SUPERIOR...MICHIGAN AND HURON IN
SEPTEMBER 2014. AT THE END OF THE MONTH...THE LAKE SUPERIOR WATER
LEVEL WAS ALMOST 9 INCHES HIGHER THAN IN SEPTEMBER 2013 AND ALMOST 7
INCHES ABOVE THE LONG TERM NORMAL. THE LEVEL OF LAKES MICHIGAN-HURON
ON 9/30 WAS ALMOST 19 INCHES HIGHER THAN DURING LAST SEPTEMBER AND
WITHIN AN INCH OF NORMAL. LAST MONTH IS THE FIRST TIME IN MANY YEARS
THAT THE WATER LEVEL ON LAKES MICHIGAN-HURON HAS BEEN NEAR NORMAL.

                      SEPTEMBER CLIMATE HIGHLIGHTS

HIGHEST REPORTED TEMPERATURE...85 NEAR ONTONAGON ON 9/27

LOWEST REPORTED TEMPERATURE...25 AT STAMBAUGH IN IRON COUNTY ON 9/12

HIGHEST AVERAGE TEMPERATURE...59.2 DEGREES AT ESCANABA

LOWEST AVERAGE TEMPERATURE...51.6 DEGREES AT STAMBAUGH

HIGHEST MONTHLY PRECIPITATION...6.54 INCHES AT IRON MOUNTAIN

LOWEST MONTHLY PRECIPITATION...2.80 INCHES AT COPPER HARBOR

THE WEATHER PATTERN OVER UPPER MICHIGAN IN SEPTEMBER 2014 WAS RATHER
CHANGEABLE WITH PERIODS OF COOL AND WET WEATHER AS WELL AS WARM AND
DRY ONES THAT CORRESPONDED TO THE PASSAGE OF UPPER TROUGHS AND
RIDGES THROUGH THE GREAT LAKES. DESPITE THE DRY PERIODS...A FEW
WIDESPREAD HEAVY RAINS RESULTED IN NORMAL TO ABOVE NORMAL RAINFALL
ACROSS MOST OF UPPER MICHIGAN. THE HEAVIEST PRECIPITATION FELL NEAR
THE WISCONSIN BORDER...WHERE MANY PLACES PICKED UP 5 INCHES OF MORE
OF RAIN DURING SEPTEMBER. UP TO 6.54 INCHES AND 6.50 INCHES FELL AT
IRON MOUNTAIN AND DAGGETT IN MENOMINEE COUNTY RESPECTIVELY. THESE
TOTALS WERE UP TO 180 PERCENT OF THE MONTHLY NORMAL. THE DRIEST AREA
WAS OVER THE NORTH HALF OF THE KEWEENAW...WHERE ONLY 2.80 INCHES
FELL AT COPPER HARBOR...ABOUT 80 PERCENT OF NORMAL.

ALTHOUGH THERE WERE PERIODS OF VERY WARM WEATHER...ESPECIALLY DURING
THE FOURTH WEEK OF SEPTEMBER WHEN MEAN DAILY TEMPERATURES RAN AS
MUCH AS 10 TO 15 DEGREES ABOVE NORMAL...VERY CHILLY WEATHER CENTERED
AROUND MID MONTH TENDED TO MORE THAN OFFSET THE WARMER PERIODS. THE
RESULT WAS A MEAN MONTHLY TEMPERATURE THAT ENDED UP BETWEEN JUST
ABOUT NORMAL TO ONE DEGREE BELOW AVERAGE. MEAN MONTHLY TEMPERATURES
BETWEEN 52 AND 59 DEGREES WERE ABOUT 5 TO 9 DEGREES LOWER THAN THE
AUGUST MEANS.

DURING THE WARMER PERIODS AT THE BEGINNING OF SEPTEMBER AND THE
FOURTH WEEK...THE MERCURY TOPPED OUT AT 80 OR HIGHER ON 9/3...
9/4...9/7 THRU 9/9...9/23 AND 9/26 THRU 9/28 AT AT LEAST A COUPLE OF
LOCATIONS. THERE WERE NO REPORTS OF 90-DEGREE TEMPERATURES IN
SEPTEMBER. WITH THE GUSTY NORTH WIND OFF THE CHILLY WATERS OF LAKE
SUPERIOR DURING THE HEAVY RAIN EVENT ON 9/10 INTO 9/11...HIGH
TEMPERATURES WERE NO HIGHER THAN THE UPPER 40S AT A NUMBER OF PLACES
ON 9/10 THROUGH 9/12...RESULTING IN SOME NEW DAILY RECORD LOW
MAXIMUMS. HIGHS IN THE 40S ALSO OCCURRED ON 9/21...AND ESPECIALLY ON
9/29 AND 9/30...WHEN A COOL CANADIAN AIRMASS INVADED THE GREAT LAKES
AND ENDED THE REIGN OF MOSTLY SUNNY AND WARM DAYS ENJOYED BY MANY ON
9/26 THROUGH 9/28. THE THERMOMETER BOTTOMED OUT IN THE 20S AT SOME
OF THE INTERIOR COLD SPOTS ON 9/12...9/15...9/16...9/18 AND 9/22.

THE GREAT MAJORITY OF THE SEPTEMBER RAIN FELL DURING THE FIRST HALF
OF THE MONTH WHEN SEVERAL STRONGER UPPER DISTURBANCES IMPACTED THE
UPPER LAKES. A LOW PRESSURE SYSTEM TRACKING THROUGH NW ONTARIO AND
ITS ATTENDANT WARM AND COLD FRONTS INTERACTED WITH A WARM AND VERY
HUMID AIRMASS TO DROP SOME HEAVY RAINS FROM LATE ON 9/3 INTO 9/5.
THE SOUTH CENTRAL U.P. SAW THE HEAVIEST RAIN DURING THIS TIME WITH
AS MUCH AS 4.00 INCHES SOAKING CARNEY IN MENOMINEE COUNTY AND 3.83
INCHES THE CITY OF MENOMINEE. THESE HEAVY RAINS CAUSED FLASH
FLOODING AT SOME SPOTS IN DICKINSON...MENOMINEE AND DELTA COUNTIES.
ONE OR TWO OF THE STORMS ALSO TURNED SEVERE IN MENOMINEE COUNTY...
WHERE SOME WIND DAMAGE OCCURRED. THE ONLY OTHER SEVERE THUNDERSTORM
IN SEPTEMBER STRUCK NEAR GERMFASK IN SCHOOLCRAFT COUNTY ON 9/2 AND
DROPPED LARGE HAIL BETWEEN 1.50 AND 1.75 INCHES IN DIAMETER.

A DEEPENING LOW PRESSURE SYSTEM MOVING THROUGH THE CENTRAL GREAT
LAKES CAUSED A WIDESPREAD RAIN EVENT ACROSS UPPER MICHIGAN ON 9/10
INTO 9/11 ALONG WITH NORTH WIND GUSTS AS HIGH AS 48 MPH AT MUNISING
AND COPPER HARBOR. OVER 2 INCHES OF RAIN FELL AT MANY PLACES...WITH
OVER 3 INCHES AT A FEW SPOTS... INCLUDING 3.34 INCHES AT BIG BAY IN
MARQUETTE COUNTY AND 3.30 INCHES AT THE CITY OF MARQUETTE. SINCE THE
STRONG NORTH WIND DRAGGED MUCH COOLER CANADIAN AIR INTO THE UPPER
LAKES AND LOWERED OVERNIGHT TEMPERATURES INTO THE 30S...THERE WERE A
FEW REPORTS THAT SNOW MIXED WITH THE RAIN NEAR WAKEFIELD IN GOGEBIC
COUNTY DURING THE NIGHT ON 9/10-9/11.

                     SEPTEMBER WEATHER SUMMARY

AS AN APPROACHING COLD FRONT AND A LOW PRESSURE WAVE MOVING
NORTHEAST ALONG THIS BOUNDARY PUSHED INTO THE GREAT LAKES ON 9/1...
NUMEROUS SHOWERS AND THUNDERSTORMS IMPACTED MAINLY THE WEST HALF OF
UPPER MICHIGAN. ALTHOUGH MOST PLACES PICKED UP LESS THAN 0.25 TO
0.50 INCH OF RAIN...UP TO 1.19 INCHES FELL AT IRONWOOD. AFTER THE
FRONT PASSED TO THE EAST...THE WEATHER OVER THE WEST TURNED MOSTLY
SUNNY AND BREEZY IN THE AFTERNOON ON 9/1 WITH WIND GUSTS UP TO 35
MPH OVER THE KEWEENAW. THERE WAS A PERIOD OF MOSTLY CLEAR CONDITIONS
IN THE EVENING ON 9/1...BUT THEN MORE CLOUDS ARRIVED DURING THE
MORNING ON 9/2 AHEAD OF A DISTURBANCE SWINGING THROUGH THE UPPER
GREAT LAKES AND WITHIN AN UPPER TROUGH OVER CENTRAL CANADA.
SCATTERED SHOWERS AND THUNDERSTORMS DEVELOPED OVER MAINLY THE EAST
HALF OF THE U.P. DURING THE AFTERNOON ON 9/2. ONE OF THE
THUNDERSTORMS TURNED SEVERE AND BOMBARDED A LOCATION NEAR GERMFASK
IN SCHOOLCRAFT COUNTY WITH HAIL BETWEEN 1.50 AND 1.75 INCHES IN
DIAMETER. AS MUCH AS 0.80 INCH OF RAIN FELL NEAR ONTONAGON UNDER A
HEAVY SHOWER. MEAN DAILY TEMPERATURES ON 9/1 AND 9/2 AVERAGED A FEW
DEGREES ABOVE NORMAL.

A LOW PRESSURE SYSTEM TRACKING THROUGH NW ONTARIO AND ITS ATTENDANT
WARM AND COLD FRONTS INTERACTED WITH A WARM AND VERY HUMID AIRMASS
TO BRING PERIODS OF SHOWERS AND THUNDERSTORMS ACROSS UPPER MICHIGAN
ON 9/3 INTO 9/5. SOME OF THESE SHOWERS DROPPED SOME TORRENTIAL
RAINS...ESPECIALLY ACROSS THE SOUTH CENTRAL U.P. AS MUCH AS 4.00
INCHES OF RAIN SOAKED CARNEY IN MENOMINEE COUNTY AND 3.83 INCHES THE
CITY OF MENOMINEE. THESE HEAVY RAINS CAUSED FLASH FLOODING AT IRON
MOUNTAIN...ESCANABA AS WELL AS SOME OTHER SPOTS IN DICKINSON...
MENOMINEE AND DELTA COUNTIES. TWO OF THE STORMS ALSO TURNED SEVERE
IN MENOMINEE COUNTY...WHERE SOME WIND DAMAGE OCCURRED AT CEDAR RIVER
IN THE AFTERNOON ON 9/4 AND NEAR DAGGETT IN THE EARLY MORNING HOURS
ON 9/5. THE PASSAGE OF THE COLD FRONT ON 9/5 ENDED THE SHOWERS AND
STORMS AS DRIER AND COOLER AIR FOLLOWED INTO THE UPPER LAKES ON THE
HEELS OF WEST WINDS GUSTING AS HIGH AS 40 MPH OVER THE KEWEENAW IN
THE MORNING. MEAN DAILY TEMPERATURES AROUND 5 DEGREES ABOVE NORMAL
ON 9/3 AND 9/4 DROPPED TO NEAR AVERAGE ON 9/5 WITH THE ARRIVAL OF
THE COOLER AIR.

HIGH PRESSURE MOVING FROM THE PLAINS ON 9/6 AND INTO THE MID
ATLANTIC STATES ON 9/7 BROUGHT DRY WEATHER TO UPPER MICHIGAN.
ALTHOUGH 9/6 WAS A BIT COOLER THAN NORMAL...THE WARMER RETURN
SOUTHWEST FLOW AROUND THE HIGH AND MOSTLY SUNNY SKIES LIFTED THE
MERCURY INTO THE 80S AT SOME PLACES IN THE AFTERNOON ON 9/7 AND THE
MEAN DAILY TEMPERATURE TO AROUND 5 DEGREES ABOVE AVERAGE. MORE
CLOUDS RETURNED ON 9/8 ASSOCIATED WITH A WEAK DISTURBANCE PASSING
THROUGH WISCONSIN...AND THERE WERE EVEN A FEW LIGHT SHOWERS OVER THE
SOUTH CENTRAL. ALTHOUGH THE CLOUDS LIMITED THE DIURNAL TEMPERATURE
RISE...THE MEAN DAILY TEMPERATURE ON 9/8 REMAINED ABOUT 5 DEGREES
ABOVE NORMAL BECAUSE OF HIGHER MORNING LOWS. A GUSTY SOUTHWEST WIND
UP TO 30 MPH ON THE WESTERN FLANK OF HIGH PRESSURE RETREATING INTO
NEW ENGLAND MADE THE DAY FEEL A BIT COOLER AS WELL.

A COLD FRONT TO THE EAST OF A DEEPENING UPPER TROUGH IN THE PLAINS
MOVED INTO THE WESTERN UPPER PENINSULA ON 9/9 BUT TENDED TO STALL
THERE DURING THE NIGHT ON 9/9-9/10 AS THE BOUNDARY BECAME PARALLEL
TO THE SOUTHWEST FLOW ALOFT TO THE EAST OF THE PLAINS UPPER TROUGH
AXIS. SHOWERS AND A FEW THUNDERSTORMS DEVELOPED OVER THE WEST AS AN
UPPER DISTURBANCE MOVED NORTHEAST ALONG THE STATIONARY FRONT...AND
THE RAIN BECAME HEAVY AT TIMES. THIS AREA OF HEAVY RAIN SHIFTED EAST
THROUGH THE DAY ON 9/10 AS AN AREA OF LOW PRESSURE OVER THE UPPER
MIDWEST MOVED NORTHEAST ALONG THE FRONTAL BOUNDARY THAT EDGED SLOWLY
ACROSS THE U.P. INCREASING NORTH WINDS ASSOCIATED WITH THE
APPROACHING LOW GUSTED AS HIGH AS 48 MPH AT MUNISING AND COPPER
HARBOR LATE IN THE AFTERNOON AND EVENING OF 9/10. ONCE THE LOW MOVED
INTO SOUTHEAST ONTARIO DURING THE NIGHT ON 9/10-9/11...THE RAIN
DIMINISHED TO SHOWERS...WHICH WERE MOST NUMEROUS IN AREAS NEAR LAKE
SUPERIOR. SOME WET SNOW MIXED IN THE WITH THE SNOW OVER THE FAR WEST
NEAR WAKEFIELD IN GOGEBIC COUNTY AS THE GUSTY NORTH WINDS ADVECTED
COLDER AIR INTO UPPER MICHIGAN. THE PRECIPITATION AND GUSTY WINDS
DIMINISHED ON 9/11 AS THE LOW TRACKED INTO QUEBEC...AND SOME
SUNSHINE RETURNED IN THE AFTERNOON IN ADVANCE OF TRAILING HIGH
PRESSURE MOVING EAST THROUGH THE NORTHERN PLAINS. TOTAL RAINFALL ON
9/10 INTO 9/11 WAS OVER 2 INCHES AT MANY PLACES...WITH OVER 3 INCHES
AT A FEW SPOTS...INCLUDING 3.34 INCHES AT BIG BAY IN MARQUETTE
COUNTY AND 3.30 INCHES AT THE CITY OF MARQUETTE. WITH LOTS OF CLOUDS
AND THE GUSTY NORTH WIND OFF THE CHILLY WATERS OF LAKE SUPERIOR...
HIGH TEMPERATURES WERE NO HIGHER THAN THE UPPER 40S AT A NUMBER OF
PLACES ON 9/10 AND 9/11...RESULTING IN SOME NEW DAILY RECORD LOW
MAXIMUMS. MEAN DAILY TEMPERATURES ON 9/9 RANGED FROM NEAR NORMAL
OVER THE WEST TO 10 DEGREES ABOVE AVERAGE ACROSS THE EAST. THE MEAN
DAILY TEMPERATURE ON 9/10 RANGED FROM ABOUT NORMAL OVER THE EAST TO
AS MUCH AS 15 TO 20 DEGREES BELOW NORMAL OVER THE WEST. ON 9/11...
THE THERMOMETER AVERAGED 10 TO 20 DEGREES BELOW AVERAGE OVER THE
ENTIRE AREA.

ANOTHER QUICK MOVING DISTURBANCE SLIDING THROUGH THE LOWER GREAT
LAKES BROUGHT THICKER CLOUDS AND MORE SHOWERS ON 9/12 INTO EARLY
9/13...MAINLY OVER THE SOUTH. MOST PLACES MEASURED NO MORE THAN 0.25
TO 0.35 INCH OF RAIN...BUT AS MUCH AS 0.56 INCH FELL AT CRYSTAL
FALLS. MORE SUNSHINE RETURNED ON 9/13 IN ADVANCE OF TRAILING HIGH
PRESSURE. SEVERAL DAILY RECORD LOW MAXIMUM TEMPERATURES FELL BY THE
WAYSIDE ON 9/12 AS THE CLOUDS AND SHOWERS LIMITED THE RISE OF THE
THERMOMETER INTO THE UPPER 40S. MEAN DAILY TEMPERATURES ON 9/12 AND
9/13 RAN ABOUT 15 DEGREES BELOW NORMAL.

A SERIES OF UPPER AIR DISTURBANCES MOVING THROUGH THE GENERAL UPPER
TROUGH OVER THE GREAT LAKES BROUGHT PERIODS OF CLOUDS AND A FEW
SHOWERS AT TIMES ON 9/14...9/15 AND 9/17...BUT ANY RAINFALL WAS
LIGHT. MORE SUNSHINE WAS THE RULE ON 9/16 AND 9/18 WHEN HIGH
PRESSURE DOMINATED. MEAN DAILY TEMPERATURES ON 9/14 THROUGH 9/18
WERE 5 TO 10 DEGREES BELOW NORMAL UNDER THE TROUGH. THE THERMOMETER
DIPPED INTO THE 20S AT SOME OF THE COLDER INTERIOR LOCATIONS ON
9/12...9/15...9/16 AND 9/18...INCLUDING THE MONTHLY LOW OF 25 AT
STAMBAUGH IN IRON COUNTY ON 9/12.

AS THE HIGH PRESSURE SYSTEM RESPONSIBLE FOR THE SUNSHINE ON 9/18
SHIFTED TO THE EAST...A STRENGTHENING SOUTH WIND DEVELOPED OVER THE
UPPER GREAT LAKES ON 9/19...DRAWING WARMER AND MOISTER AIR OVER
UPPER MICHIGAN. SOUTH WIND GUSTS AS HIGH AS 40 TO 45 MPH DURING THE
DAY ON 9/19 INCREASED UP TO 58 MPH AT GRAND MARAIS IN ALGER COUNTY
IN THE EVENING. THESE GUSTY WINDS DOWNED SOME TREES IN LUCE COUNTY
BEFORE THE WINDS DIMINISHED DURING THE EARLY MORNING ON 9/20. THE
INTERACTION BETWEEN THE MOISTER AIR DRAWN NORTH BY THESE WINDS AND
AN UPPER DISTURBANCE TRACKING THROUGH NORTHWEST ONTARIO RESULTED IN
SCATTERED SHOWERS AND EVEN A FEW THUNDERSTORMS LATE ON 9/19 INTO THE
MORNING ON 9/20. THE PASSAGE OF THE COLD FRONT ASSOCIATED WITH THAT
DISTURBANCE ON 9/20 WAS ACCOMPANIED BY ONLY ISOLATED SHOWERS.
RAINFALL ON 9/19 INTO 9/20 WAS MODEST...WITH NO MORE THAN 0.30 INCH
REPORTED AT JACOBSVILLE IN HOUGHTON COUNTY. A NEAR NORMAL MEAN DAILY
TEMPERATURE ON 9/19 ROSE TO ABOUT 10 DEGREES ABOVE AVERAGE ON 9/20
BEFORE SOMEWHAT COOLER AIR FOLLOWED THE COLD FRONTAL PASSAGE LATE IN
THE DAY.

ANOTHER STRONGER COLD FRONT SWEPT SOUTH ACROSS UPPER MICHIGAN DURING
THE NIGHT ON 9/20-9/21 ACCOMPANIED BY SOME SHOWERS. NORTHEAST WINDS
GUSTING AS HIGH AS 35 TO 40 MPH IN THE MORNING ON 9/21 CAUSED MORE
NUMEROUS SHOWERS TO PERSIST OVER THE HIGHER TERRAIN NEAR LAKE
SUPERIOR AS MUCH COOLER AIR FOLLOWED. AS HIGH PRESSURE PUSHED EAST
INTO MINNESOTA LATER ON 9/20...THE SHOWERS AND WINDS DIMINISHED...
AND SOME SUNSHINE RETURNED OVER THE WEST. EVEN THOUGH THERE WERE
SOME CLOUDS ON 9/22...HIGH PRESSURE MOVING TOWARD THE OHIO RIVER
VALLEY RESULTED IN DRY WEATHER. MEAN DAILY TEMPERATURES RUNNING NEAR
10 DEGREES BELOW AVERAGE ON 9/21 REBOUNDED TO WITHIN A FEW DEGREES
OF NORMAL ON 9/22...THE FIRST DAY OF FALL 2014.

ALTHOUGH THE CALENDAR SAID THE SEASON WAS NOW FALL...A BUILDING
RIDGE OF HIGH PRESSURE ALOFT CAUSED THE SURFACE HIGH PRESSURE SYSTEM
OVER THE OHIO RIVER VALLEY TO MEANDER BETWEEN THE LOWER GREAT LAKES
AND NEW ENGLAND MUCH OF THE FOURTH WEEK OF SEPTEMBER. THE RESULT WAS
AN EXTENDED PERIOD OF GENERALLY CLEAR TO PARTLY CLOUDY AND WARM
WEATHER THAT FEATURED MEAN DAILY TEMPERATURES BETWEEN 5 AND 15
DEGREES ABOVE NORMAL FROM 9/23 THROUGH 9/28 AS THE SOUTHWEST FLOW
AROUND THE SURFACE HIGH PRESSURE PUMPED MILDER AIR INTO THE UPPER
LAKES. THE MERCURY TOPPED OUT IN THE 80S ON 9/23...9/26...9/27 AND
9/28 AT AT LEAST A COUPLE OF LOCATIONS. THE WARMEST AFTERNOONS ON
9/27 AND 9/28 FEATURED SOME RECORD HIGH MAXIMUMS...INCLUDING THE
MONTHLY HIGH OF 85 NEAR ONTONAGON 9/27. WITH LENGTHENING NIGHTS...
SOME LOCALLY DENSE FOG DEVELOPED OVER MAINLY THE SOUTHEAST U.P. NEAR
LAKE MICHIGAN DURING THE NIGHTS IN THIS PERIOD.

THE ARRIVAL OF SOME SHOWERS OVER NORTHERN UPPER MICHIGAN LATER IN
THE DAY ON 9/28 HERALDED THE APPROACH OF A COLD FRONT AND A RETURN
OF MUCH COOLER...MORE TYPICAL AUTUMNAL WEATHER FOR THE LAST TWO DAYS
OF SEPTEMBER. THE PASSAGE OF THE FRONT DURING THE NIGHT OF 9/28-9/29
WAS FOLLOWED BY NUMEROUS SHOWERS INTO THE MORNING ON 9/29 THAT
DROPPED 0.25 TO 0.50 INCH OF RAIN AT MANY SPOTS. TAHQUAMENON FALLS
NEAR THE EASTERN BORDER OF LUCE COUNTY SAW THE MOST PRECIPITATION
WITH 0.80 INCH. EVEN AFTER THE SHOWERS DIMINISHED BY AFTERNOON ON
9/29...PLENTY OF CLOUDS LINGERED...ALONG WITH SOME DRIZZLE MAINLY
OVER THE HIGHER TERRAIN OVER THE NORTH. THE COMBINATION OF THE
PRECIPITATION...CLOUDS AND STEADY NORTH WIND TO THE SOUTH OF HIGH
PRESSURE IN ONTARIO RESULTED IN HIGH TEMPERATURES ON 9/29 THAT WERE
MAINLY IN THE 40S OVER THE NORTH...AS MUCH AS 30 DEGREES LOWER THAN
THE DAY BEFORE. THE CLOUDS LINGERED THROUGH THE MORNING ON 9/30 BEFORE
SOME DRIER AIR ASSOCIATED WITH THE ONTARIO HIGH BROUGHT A RETURN OF
PARTLY TO MOSTLY SUNNY BUT STILL VERY COOL WEATHER IN THE AFTERNOON.
THE MERCURY AVERAGED 5 TO 10 DEGREES BELOW NORMAL ON 9/29 AND 9/30.

                         NOVEMBER 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
NOVEMBER 2014.

                        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.
