...GREAT LAKES WATER LEVELS RISE SLOWLY IN JULY...

THE COMBINATION OF RUNOFF FROM HEAVY PRECIPITATION THIS YEAR AS WELL
AS REDUCED EVAPORATION DUE TO CHILLY WATER TEMPERATURES CAUSED GREAT
LAKES WATER LEVELS TO RISE SLOWLY IN JULY. BY THE END OF JULY...THE
LAKE SUPERIOR WATER LEVEL WAS OVER 12 INCHES HIGHER THAN IN JULY
2013 AND ABOUT 7 INCHES ABOVE THE LONG TERM NORMAL. THE LEVEL OF
LAKES MICHIGAN/HURON ON 7/31 WAS ABOUT 15 INCHES HIGHER THAN DURING
LAST JULY BUT STILL ABOUT 4 INCHES BELOW THE LONG TERM AVERAGE.

                        JULY CLIMATE HIGHLIGHTS

HIGHEST REPORTED TEMPERATURE...93 NEAR ONTONAGON AND BARAGA ON 7/21

LOWEST REPORTED TEMPERATURE...32 AT A SITE 10 MILES NORTHWEST OF
                               NEWBERRY ON 7/10 AND 7/17

HIGHEST AVERAGE TEMPERATURE...65.4 DEGREES NEAR ESCANABA

LOWEST AVERAGE TEMPERATURE...59.0 DEGREES AT STAMBAUGH IN IRON COUNTY

HIGHEST MONTHLY PRECIPITATION...5.96 INCHES AT HERMAN IN BARAGA
                                 COUNTY

LOWEST MONTHLY PRECIPITATION...1.31 INCHES AT MANISTIQUE

AN UPPER TROUGH WAS PRESENT OVER EASTERN NORTH AMERICA MOST OF THE
TIME IN JULY 2014...RESULTING IN A COOLER THAN NORMAL MONTH ACROSS
ALL OF UPPER MICHIGAN AS THE NORTHWEST FLOW ALOFT TO THE WEST OF THE
TROUGH AXIS ALLOWED FOR FREQUENT INCURSIONS OF CANADIAN AIRMASSES.
MEAN MONTHLY TEMPERATURES RANGED FROM 2 TO NEARLY 5 DEGREES BELOW
NORMAL OVER THE EAST FROM MANISTIQUE TO NEWBERRY. THESE RELATIVELY
CHILLY CONDITIONS WERE DUE MAINLY TO COOL DAYTIME TEMPERATURES. IN
FACT...THERE WERE NO OCCURRENCES OF 80-DEGREE TEMPERATURES AT
NEWBERRY IN JULY FOR THE FIRST TIME SINCE 1992. THE JULY MONTHLY
AVERAGE TEMPERATURES BETWEEN 59 AND 65 DEGREES WERE WITHIN A FEW
DEGREES OF THE JUNE AVERAGES AT MOST PLACES BUT UP TO 4 TO 7 DEGREES
WARMER AT SOME LOCATIONS NEAR THE GREAT LAKES DUE TO THE STEADILY
INCREASING NEARSHORE WATER TEMPERATURES. MANISTIQUE STILL
EXPERIENCED THE SECOND COOLEST JULY ON RECORD...AND THE MONTH ENDED
UP AS ONE OF THE TOP TEN COOLEST JULYS AT MANY OTHER LOCATIONS.

DESPITE THE PERSISTENCE OF THE UPPER TROUGH...MOST PLACES ACROSS THE
U.P. SAW DRIER THAN NORMAL CONDITIONS IN JULY. THE ONLY EXCEPTION
WAS IN THE AREA NORTH OF A LINE FROM THE PORCUPINE MOUNTAINS TO
MUNISING...WHERE 3.50 TO 4.50 INCHES OF RAIN WAS COMMON. AS MUCH AS
5.96 INCHES OF RAIN FELL OVER THE HIGHER TERRAIN OF THE HURON
MOUNTAINS AT HERMAN IN BARAGA COUNTY...CLOSE TO 140 PERCENT OF THE
TYPICAL JULY PRECIPITATION THERE. MANISTIQUE REPORTED THE LEAST RAIN
WITH 1.31 INCHES...ONLY 43 PERCENT OF THE NORMAL 3.04 INCHES. IN
GENERAL...THE FIRST HALF OF JULY WAS WETTER THAN THE SECOND HALF OF
THE MONTH.

THE MEAN DAILY TEMPERATURE ON MOST DAYS IN JULY RAN BELOW NORMAL.
THE COOLEST WEATHER OCCURRED WHEN THE UPPER TROUGH IN EASTERN NORTH
AMERICA WAS DEEPEST ON 7/8 INTO 7/10...7/14 INTO 7/17...AND AGAIN ON
7/27 INTO 7/28. MEAN DAILY TEMPERATURES ON THESE DAYS RAN FROM AS
MUCH AS 10 TO 15 DEGREES BELOW AVERAGE. AT LEAST ONE OF THE COLDER
INTERIOR LOCATIONS SAW THE MERCURY DIP INTO THE 30S IN THE EARLY
MORNING HOURS OF 7/3...7/4...7/10...7/16...7/17...7/24 AND 7/30.
READINGS WERE NO HIGHER THAN THE 50S AT SOME LOCATIONS ON 7/8...
7/14...7/15 AND 7/27. THE ONLY REAL SUMMER-LIKE WEATHER IN JULY
OCCURRED ON 7/20 INTO 7/22...WHEN AN UPPER RIDGE BUILT INTO THE
GREAT LAKES. A FEW LOCATIONS SAW THE MERCURY REACH 90 OR HIGHER ON
7/21...INCLUDING THE MONTHLY MAXIMUM OF 93 JUST INLAND FROM
ONTONAGON AND AT SOME LOCATIONS WEST OF BARAGA. 7/21 WAS THE ONLY
DAY WHEN ANY SPOT IN UPPER MICHIGAN REPORTED A HIGH TEMPERATURE AT
OR ABOVE 90 IN JULY 2014.

THE INTERACTION BETWEEN A WARM AND HUMID AIRMASS IN THE GREAT LAKES
AND A PAIR OF UPPER DISTURBANCES MOVING ALONG THE CANADIAN BORDER
BROUGHT ROUNDS OF SHOWERS AND THUNDERSTORMS TO MOST OF UPPER
MICHIGAN FROM LATE ON 7/5 THROUGH 7/6. SOME OF THESE SHOWERS DROPPED
TORRENTIAL DOWNPOURS. AN INCH OR MORE OF RAIN WAS COMMON OVER MUCH
OF THE CENTRAL UPPER PENINSULA...WITH AS MUCH AS 1.85 INCHES
INUNDATING A LOCATION NEAR BIG BAY IN MARQUETTE COUNTY. ONE OF THE
STRONGER THUNDERSTORMS DOWNED TREES AT ISHPEMING IN MARQUETTE COUNTY
IN THE EVENING ON 7/6. SOME ADDITIONAL MODERATE HEAVY RAIN FELL FROM
LATE ON 7/7 INTO 7/8 AS A REINFORCING COLD FRONT SWEPT THROUGH THE
UPPER LAKES BEHIND THE DEPARTING STRONG DISTURBANCE THAT BROUGHT THE
ACTIVE WEATHER ON 7/6. PAULDING IN ONTONAGON COUNTY LED REPORTING
STATIONS WITH 2.04 INCHES OF RAIN ON 7/7 INTO 7/8. VERY COOL AIR
INVADED THE UPPER GREAT LAKES BEHIND THIS FRONTAL PASSAGE...AND MANY
LOCATIONS REPORTED HIGH TEMPERATURES ONLY IN THE 50S ON 7/8. SOME
PLACES OBSERVED NEW RECORD LOW MAXIMUM TEMPERATURES.

ANOTHER VERY COOL CANADIAN AIRMASS SPILLED INTO THE UPPER GREAT
LAKES ON 7/14 AND 7/15 AS AN UPPER TROUGH DEEPENED OVER THE AREA.
OVER THE WEST WHERE CLOUDS AND THE COOL AIR ARRIVED EARLIEST...THE
MERCURY NEVER ROSE OUT OF THE 50S AT SOME PLACES ON 7/14. CLOUDS AND
SOME SHOWERS HELD HIGH TEMPERATURES IN THE 50S AT MANY PLACES ON
7/15... ESTABLISHING NEW DAILY RECORD LOW MAXIMUMS AT A NUMBER OF
LOCATIONS. AT GRAND MARAIS IN ALGER COUNTY...THE THERMOMETER NEVER
READ HIGHER THAN 47 ON 7/15. ALTHOUGH RAINFALL WAS NOT EXCESSIVE...
AS MUCH AS 0.91 INCH INCH FELL AT HERMAN OVER THE HIGHER TERRAIN OF
THE HURON MOUNTAINS IN BARAGA COUNTY ON 7/14 INTO 7/15.

THE WARM AIRMASS THAT INVADED THE UPPER LAKES ON 7/20 AND LIFTED THE
MERCURY INTO THE 90S AT A FEW PLACES ON 7/21 WAS ALSO QUITE HUMID.
AS A POTENT DISTURBANCE MOVED INTO THE GREAT LAKES EARLY ON 7/22 AND
INTERACTED WITH THIS UNSTABLE AIR...SOME THUNDERSTORMS WITH HEAVY
RAIN AND DAMAGING WINDS OCCURRED MAINLY OVER THE WEST AND NORTH
CENTRAL. THE STRONGEST STORM DOWNED A NUMBER OF TREES NEAR BIG BAY
IN MARQUETTE COUNTY. AS MUCH AS 1.04 INCHES OF RAIN FELL AT PELKIE
IN BARAGA COUNTY NEAR THE HOUGHTON COUNTY LINE. THESE THUNDERSTORMS
ALSO CAUSED A SEICHE ON LAKE SUPERIOR THAT RESULTED IN LARGE
FLUCTUATIONS OF AS MUCH AS 3 FEET IN LAKE LEVEL AT AND AROUND
MUNISING IN THE MORNING ON 7/22. THESE WATER RISES RESULTED IN SOME
MINOR FLOODING THAT DAMAGED SOME DOCKS ON THE EAST SIDE OF MUNISING
BAY.

THE PASSAGE OF TWO LOW PRESSURE SYSTEMS THROUGH THE UPPER LAKES
ASSOCIATED WITH THE DEEPENING UPPER TROUGH ACROSS EASTERN NORTH
AMERICA BROUGHT ANOTHER ROUND OF SOME LOCALLY HEAVY SHOWERS FROM
LATE ON 7/25 INTO 7/27...ESPECIALLY ACROSS THE EAST CENTRAL U.P.
GARDEN CORNERS IN DELTA COUNTY LOGGED 2.36 INCHES OF RAIN DURING
THIS TIME. A FEW PLACES NEAR THE CHILLY WATERS OF LAKE SUPERIOR EAST
OF MARQUETTE REPORTED HIGH TEMPERATURES IN THE 50S ON 7/27 AS VERY
COOL AIR FOLLOWED THE COLD FRONT ASSOCIATED WITH THE SECOND LOW.
GRAND MARAIS WAS THE COOL SPOT AGAIN WITH A MAXIMUM TEMPERATURE OF
55 ON 7/27.

                        JULY WEATHER SUMMARY

AS AN UPPER TROUGH DEEPENED OVER THE WESTERN GREAT LAKES...A STRONG
COLD FRONT SWEPT ACROSS UPPER MICHIGAN ON 7/1. NUMEROUS SHOWERS AND
A FEW THUNDERSTORMS...ALONG WITH SOME PATCHY DENSE FOG NEAR LAKE
MICHIGAN...AS WELL AS NEAR NORMAL TEMPERATURES WERE THE RULE AHEAD
OF THE FRONTAL PASSAGE. RAINFALL ON 7/1 WAS GENERALLY NO MORE THAN
0.25 TO 0.50 INCH...BUT SOME PLACES THAT SAW HEAVIER SHOWERS PICKED
UP OVER AN INCH OF RAIN...INCLUDING 1.20 INCHES AT A RURAL LOCATION
ON THE BORDER OF NORTHEAST DELTA AND NORTHWEST SCHOOLCRAFT COUNTIES.
ALTHOUGH THE BULK OF THE SHOWERS SHIFTED TO THE SOUTHEAST FOLLOWING
THE FRONTAL PASSAGE...LINGERING LOW LEVEL MOISTURE MAINTAINED SOME
LOW CLOUDS AND DRIZZLE DURING THE NIGHT ON 7/1-7/2 BEFORE THE
ARRIVAL OF DRIER AIR RESULTED IN A RETURN OF MORE SUNSHINE IN THE
AFTERNOON ON 7/2. CANADIAN HIGH PRESSURE TRAILING THE FRONT THEN
BROUGHT SOME MOSTLY CLEAR AND PLEASANTLY COOL WEATHER TO THE U.P.
THROUGH INDEPENDENCE DAY...PROVIDING IDEAL WEATHER FOR AREA
FIREWORKS DISPLAYS. THE EARLY MORNINGS ON 7/3 AND 7/4 WERE RATHER
CHILLY...WITH THE THERMOMETER READING IN THE 30S AT SOME OF THE
COLDER INTERIOR LOCATIONS. THE MERCURY SANK AS LOW AS 34 AT A SITE
INLAND FROM MUNISING ON 7/3 AND 33 NEAR NEWBERRY ON 7/4. MEAN DAILY
TEMPERATURES ON 7/2 THROUGH 7/4 AVERAGED AROUND 5 DEGREES BELOW
NORMAL.

ONCE THE HIGH PRESSURE RESPONSIBLE FOR THE PLEASANT WEATHER ON
INDEPENDENCE DAY SHIFTED TO THE SOUTHEAST...A SOUTHWEST FLOW
DEVELOPED AND BROUGHT A RETURN OF WARMER AND MORE HUMID AIR ON 7/5
AND 7/6. ALTHOUGH A FEW SHOWERS ACCOMPANIED THE ARRIVAL OF THE
WARMER AIR IN THE MORNING ON 7/5...MOST PLACES THAT PICKED UP RAIN
SAW NO MORE THAN 0.10 INCH. AFTER MORE SUNSHINE IN THE AFTERNOON ON
7/5 THAT INCREASED THE INSTABILITY OF THE ATMOSPHERE...THE APPROACH
OF A PAIR OF UPPER DISTURBANCES AND A STRONG COLD FRONT TRAILING THE
SECOND OF THESE BROUGHT PERIODS OF MORE NUMEROUS SHOWERS AND
THUNDERSTORMS FROM LATE ON 7/5 INTO THE EVENING ON 7/6. THE HEAVIER
SHOWERS AND STORMS DUMPED SOME TORRENTIAL RAIN...AND A FEW OF THE
THUNDERSTORMS TURNED SEVERE IN THE LATE AFTERNOON AND EVENING ON
7/6. AN INCH OR MORE OF RAIN WAS COMMON OVER MUCH OF THE CENTRAL
UPPER PENINSULA...WITH AS MUCH AS 1.85 INCHES INUNDATING A LOCATION
NEAR BIG BAY IN MARQUETTE COUNTY. ONE OF THE STRONGER THUNDERSTORMS
DOWNED TREES AT ISHPEMING IN MARQUETTE COUNTY IN THE EVENING ON 7/6
AS THE COLD FRONT SURGED INTO UPPER MICHIGAN. FOLLOWING THE FRONTAL
PASSAGE...APPROACHING HIGH PRESSURE AND DRIER AIR BROUGHT A RETURN
OF MOSTLY CLEAR SKIES AND PLEASANTLY WARM WEATHER THROUGH MUCH OF
7/7. MEAN DAILY TEMPERATURES AROUND 5 DEGREES ABOVE AVERAGE ON 7/5
AND 7/6 DROPPED TO AROUND NORMAL ON 7/7.

ANOTHER COLD FRONT ASSOCIATED WITH A DEEPENING UPPER TROUGH OVER THE
GREAT LAKES CROSSED THE U.P. DURING THE NIGHT ON 7/7-7/8...BRINGING
NUMEROUS SHOWERS AND A FEW THUNDERSTORMS TO THE AREA. SOME OF THESE
SHOWERS LINGERED INTO THE MORNING ON 7/8 AS A STEADY NORTH WIND BLEW
SOME VERY COOL CANADIAN AIR OVERHEAD. MOST LOCATIONS PICKED UP 0.25
TO 0.75 INCH OF RAIN DURING THIS EVENT...BUT AN INCH OR MORE FELL AT
SOME LOCATIONS. PAULDING IN ONTONAGON COUNTY LED REPORTING STATIONS
WITH 2.04 INCHES OF RAIN...AND A SITE NEAR IRON RIVER PICKED UP 1.48
INCHES. THE COMBINATION OF THE CHILLY FLOW OVER THE COLD LAKE
SUPERIOR WATERS AND EXTENSIVE CLOUD COVER LED TO SOME RECORD LOW
MAXIMUM TEMPERATURES IN THE 50S DURING THE AFTERNOON ON 7/8. GRAND
MARAIS WAS THE COOL SPOT WITH A HIGH OF ONLY 51. THE CLOUDS AND
ISOLATED SHOWERS LINGERED INTO THE AFTERNOON ON 7/9...WHEN THE
APPROACH OF HIGH PRESSURE BROUGHT A RETURN OF MORE SUNSHINE AND
MODERATE TEMPERATURES. UNDER A MOSTLY CLEAR SKY...THE MERCURY
PLUNGED INTO THE 30S AT MANY OF THE COOLER INTERIOR LOCATIONS EARLY
ON 7/10 AS THE HIGH MOVED OVER THE UPPER LAKES AND WINDS TURNED CALM.
THE THERMOMETER READ AS LOW AS 32 AT A RURAL LOCATION JUST NORTHWEST
OF NEWBERRY.  MOSTLY SUNNY AND PLEASANT WEATHER WAS THE RULE DURING
THE DAY ON 7/10 AS THE HIGH SHIFTED OVER LOWER MICHIGAN. MEAN DAILY
TEMPERATURES BETWEEN 10 AND 15 DEGREES BELOW NORMAL ON 7/8 MODERATED
TO AROUND 10 DEGREES BELOW AVERAGE ON 7/9 AND NEAR 5 DEGREES BELOW
NORMAL ON 7/10.

AS THE HIGH RESPONSIBLE FOR THE PLEASANT WEATHER ON 7/10 SHIFTED TO
THE EAST...THE RETURN SOUTHWEST FLOW ON ITS WESTERN FLANK PUMPED
SOME WARMER AND MOISTER AIR BACK INTO THE UPPER LAKES. THE RESULT
FOR UPPER MICHIGAN WAS AN INCREASE IN CLOUD COVER ON 7/11 ALONG WITH
SOME SHOWERS...MAINLY OVER THE WEST. THESE SHOWERS DROPPED 0.10 TO
0.50 INCH OR MORE OF RAIN AT SOME PLACES...INCLUDING 0.60 INCH AT
LAKE LINDEN IN HOUGHTON COUNTY. THE SHOWERS AND THUNDERSTORMS
OVERSPREAD THE REST OF THE U.P. ON 7/12 AS A COLD FRONT MOVED ACROSS
THE UPPER LAKES. ALTHOUGH MOST PLACES SAW NO MORE THAN 0.10 TO 0.25
INCH OF PRECIPITATION...SOME HEAVY RAIN FELL UNDER SOME OF THE MORE
INTENSE SHOWERS. LA BRANCHE IN MENOMINEE COUNTY LOGGED AS MUCH AS
0.98 INCH. ONE OF THE STORMS THAT PASSED NEAR MARQUETTE ALSO DROPPED
SOME SMALL HAIL IN THE EVENING ON 7/12 AND UP TO 0.67 INCH OF RAIN
NEAR ISHPEMING. COOLER AIR OVERSPREAD THE AREA ON 7/13 BEHIND THE
FRONTAL PASSAGE AND UNDER A DEEPENING UPPER TROUGH. ALTHOUGH THE
ARRIVAL OF DRIER AIR ALOFT DIMINISHED THE SHOWERS...THERE WAS ENOUGH
LOW LEVEL MOISTURE FOR SOME CLOUDS AND SPRINKLES TO LINGER ON 7/13.
THE THERMOMETER AVERAGED FROM NEAR NORMAL TO 5 DEGREES ABOVE THE
MEAN ON 7/11 AND 7/12 BUT THEN FELL OFF TO AS MUCH AS 5 DEGREES
BELOW NORMAL ON 7/13.

A STEADY NORTH WIND BETWEEN CANADIAN HIGH PRESSURE BUILDING INTO THE
NORTHERN PLAINS AND LOW PRESSURE DEVELOPING OVER THE SOUTHEAST GREAT
LAKES UNDER THE DEEPENING UPPER TROUGH ADVECTED UNSEASONABLY CHILLY
AIR INTO THE GREAT LAKES ON 7/14 AND 7/15. THERE WERE PLENTY OF
CLOUDS AND NUMEROUS MAINLY LIGHT RAIN SHOWERS THAT BEGAN TO DIMINISH
ON 7/15 AS THE LOW PRESSURE SYSTEM BEGAN TO MOVE EAST AWAY FROM THE
AREA. OVER THE WEST WHERE CLOUDS AND THE COOL AIR ARRIVED
EARLIEST...THE MERCURY NEVER ROSE OUT OF THE 50S AT SOME PLACES ON
7/14...WITH READINGS NO HIGHER THAN 58 AT PAULDING AND GREENLAND IN
ONTONAGON COUNTY. MANY PLACES OVER THE ENTIRE U.P. REPORTED
HIGH TEMPERATURES IN THE 50S ON 7/15... ESTABLISHING NEW DAILY
RECORD LOW MAXIMUMS AT A NUMBER OF LOCATIONS. AT GRAND MARAIS IN
ALGER COUNTY...THE THERMOMETER NEVER READ HIGHER THAN 47 ON 7/15.
ALTHOUGH RAINFALL WAS NOT EXCESSIVE AND GENERALLY NOT MORE THAN 0.25
TO 0.50 INCH...AS MUCH AS 0.91 INCH FELL AT HERMAN OVER THE HIGHER
TERRAIN OF THE HURON MOUNTAINS IN BARAGA COUNTY ON 7/14 INTO 7/15.
AS HIGH PRESSURE IN THE PLAINS EDGED CLOSER...THE CLOUDS GAVE WAY TO
MORE SUNSHINE BY THE AFTERNOON ON 7/16...MODERATING THE AUTUMNAL
CHILL. MEAN DAILY TEMPERATURES RANGED FROM 5 TO 15 DEGREES BELOW
NORMAL ON 7/14...WERE 15 TO 20 DEGREES BELOW AVERAGE ON 7/15 AND
THEN AROUND 10 DEGREES BELOW NORMAL ON 7/16. A NUMBER OF THE COLDER
INTERIOR LOCATIONS SAW THE MERCURY SINK INTO THE 30S DURING THE
NIGHTS ON 7/15-7/16 AND 7/16-7/17. READINGS WERE AS LOW AS 37 AT
WAKEFIELD IN GOGEBIC COUNTY EARLY ON 7/16 AND 32 AT A SITE 10 MILES
NORTHWEST OF NEWBERRY AT SUNRISE ON 7/17.

ONCE THE HIGH RESPONSIBLE FOR THIS COOL STRETCH SHIFTED TOWARD THE
MID ATLANTIC STATES...A WARMING TREND BEGAN DURING THE DAY ON 7/17
AND CONTINUED INTO 7/22. EXCEPT FOR SOME CLOUDS THAT ACCOMPANIED THE
RETURN OF THE WARMER AND MOISTER AIRMASS AND EVEN A FEW SPRINKLES ON
7/19...THE PERIOD FROM 7/17 THROUGH 7/21 WAS DRY. SOUTHWEST WINDS
GUSTING TO 30 MPH ON 7/20 DREW THE HOTTEST AIRMASS OF THE SEASON
INTO THE UPPER GREAT LAKES...WITH MAXIMUM TEMPERATURES ON 7/21
REACHING 90 OR ABOVE AT A FEW LOCATIONS AWAY FROM THE MODERATING
INFLUENCE OF LAKE MICHIGAN. THE HIGHEST TEMPERATURE REPORTED ON 7/21
WAS 93 NEAR ONTONAGON AND BARAGA. RESIDENTS OF PELKIE IN BARAGA
COUNTY NEAR THE HOUGHTON COUNTY LINE ALSO ENDURED AN UNCOMFORTABLE
NIGHT OF SLEEPING ON 7/21-7/22...WHEN THE THERMOMETER THERE NEVER
FELL LOWER THAN 70 DEGREES. MEAN DAILY TEMPERATURES ROSE FROM ABOUT
5 DEGREES BELOW NORMAL ON 7/17 TO 10 DEGREES ABOVE AVERAGE ON 7/21.

AS A POTENT DISTURBANCE MOVED INTO THE GREAT LAKES IN THE EARLY
MORNING ON 7/22 AND INTERACTED WITH THE WARM...UNSTABLE AIRMASS IN
PLACE...SOME THUNDERSTORMS WITH HEAVY RAIN AND DAMAGING WINDS
OCCURRED MAINLY OVER WEST AND NORTH CENTRAL. THE STRONGEST STORM
DOWNED TREES NEAR BIG BAY IN MARQUETTE COUNTY. MANY LOCATIONS OVER
THE WEST AND NORTH CENTRAL MEASURED 0.50 TO 1.00 INCH OF RAIN...AND
AS MUCH AS 1.04 INCHES FELL AT PELKIE. THE THUNDERSTORMS ALSO CAUSED
A SEICHE ON LAKE SUPERIOR THAT RESULTED IN LARGE FLUCTUATIONS OF AS
MUCH AS 3 FEET IN LAKE LEVEL AT AND AROUND MUNISING AFTER SUNRISE ON
7/22. THESE WATER RISES RESULTED IN SOME MINOR FLOODING THAT DAMAGED
SOME DOCKS ON THE EAST SIDE OF MUNISING BAY. THE COLD FRONT
ASSOCIATED WITH THE UPPER DISTURBANCE CLEARED THE U.P. IN THE
AFTERNOON...ENDING ANY SHOWERS AND STORMS THAT LINGERED OVER MAINLY
THE NORTH CENTRAL. WEST WINDS GUSTING UP TO 45 MPH OVER THE KEWEENAW
BEHIND THE FRONT DROVE LESS HUMID AIR INTO THE AREA. MUCH COOLER AIR
ARRIVED AFTER SUNSET ON 7/22 FOLLOWING THE PASSAGE OF A SECOND COLD
FRONT THAT GENERATED A FEW SPRINKLES ACROSS THE WEST. THIS OUTBREAK
OF COOLER AIR DROPPED THE MEAN DAILY TEMPERATURE ON 7/22 TO NEAR
NORMAL.

CANADIAN HIGH PRESSURE FOLLOWING THE FRONT BROUGHT MOSTLY CLEAR AND
COOL CONDITIONS ON 7/23 AND 7/24. AS THE ANTICYCLONE MOVED OVERHEAD
DURING THE NIGHT ON 7/23-7/24...THE COMBINATION OF CLEAR SKIES AND
LIGHT WINDS ALLOWED THE MERCURY TO PLUNGE INTO THE 30S AT THE COOLER
INTERIOR LOCATIONS AND AS LOW AS 33 INLAND FROM MUNISING AND JUST
NORTHWEST OF NEWBERRY AT DAYBREAK ON 7/24. MEAN DAILY TEMPERATURES
ON BOTH DAYS RAN 5 TO 10 DEGREES BELOW AVERAGE. ONCE THE HIGH CENTER
SHIFTED TOWARD THE MID ATLANTIC STATES...A RETURN SOUTHWEST FLOW
ADVECTED WARMER AND MORE HUMID AIR INTO UPPER LAKES. MORE CLOUDS AND
SOME SCATTERED SHOWERS DEVELOPED OVER THE WEST AS EARLY AS 7/25 WELL
IN ADVANCE OF AN APPROACHING COLD FRONT. AS THE FRONT MOVED
CLOSER...THESE SHOWERS AND SOME THUNDERSTORMS OVERSPREAD THE REST OF
THE AREA DURING THE NIGHT ON 7/25-7/26...WHEN PATCHY FOG ALSO
DEVELOPED IN THE MORE HUMID AIRFLOW. AS MUCH AS 0.99 INCH AND 0.94
INCH OF RAIN FELL UNDER THE HEAVIER SHOWERS AT GARDEN CORNERS AND
NAHMA JUNCTION RESPECTIVELY IN DELTA COUNTY THROUGH DAYBREAK ON 7/26.
MORE SHOWERS AND STORMS MOVED OVER MAINLY THE NORTH CENTRAL AND EAST
ON 7/26...WHEN THE COLD FRONT SURGED ACROSS THE AREA AND OPENED THE
DOOR TO A COOLER AND DRIER AIRMASS UNDER ANOTHER DEEPENING TROUGH
OVER EASTERN NORTH AMERICA. ONE OF THE STRONGER STORMS IN THE
AFTERNOON ON 7/26 KNOCKED DOWN SOME TREES AT GLADSTONE IN DELTA
COUNTY. THE SHOWERS ON 7/26 ALSO CAUSED SOME HEAVY RAIN IN EXCESS OF
0.25 TO 0.50 INCH...ESPECIALLY OVER THE SOUTHEAST. SEVERAL LOCATIONS
IN THIS AREA SAW AN INCH OR MORE OF RAIN...INCLUDING 1.41 INCHES AT
A SITE NEAR STEUBEN IN SCHOOLCRAFT COUNTY AND ANOTHER 1.12 INCHES AT
GARDEN CORNERS. THE THERMOMETER AVERAGED WITHIN A FEW DEGREES OF
NORMAL ON 7/25 AND FROM NEAR NORMAL TO 5 DEGREES ABOVE THE MEAN ON
7/26.

ALTHOUGH CONDITIONS WERE MOSTLY CLEAR IN THE EVENING ON 7/26... MORE
CLOUDS AND ANOTHER ROUND OF SHOWERS AND A FEW THUNDERSTORMS ARRIVED
IN THE EARLY MORNING HOURS ON 7/27 AS A LOW PRESSURE SYSTEM EMBEDDED
IN THE NORTHWEST FLOW ALOFT ON THE WESTERN FLANK OF THE DEEPENING
EASTERN TROUGH MOVED FROM MINNESOTA THROUGH NORTHERN WISCONSIN.
AREAS OF LOCALLY DENSE FOG ALSO DEVELOPED...MAINLY NEAR THE CHILLY
WATERS OF LAKE SUPERIOR. THE SHOWERS AND FOG PERSISTED INTO THE
EARLY AFTERNOON BEFORE HIGH PRESSURE IN ONTARIO PUSHED A DRIER
CANADIAN AIRMASS OVER THE UPPER GREAT LAKES AND SKIES BEGAN TO
CLEAR. ANOTHER 0.25 TO 0.50 INCH OR MORE OF RAIN FELL ACROSS MUCH OF
THE UPPER PENINSULA. CLARKSBURG-CHAMPION IN MARQUETTE COUNTY LED
REPORTING STATIONS WITH 0.91 INCH OF PRECIPITATION. A FEW PLACES
NEAR THE CHILLY WATERS OF LAKE SUPERIOR EAST OF MARQUETTE REPORTED
HIGH TEMPERATURES IN THE 50S ON 7/27. GRAND MARAIS WAS THE COOL SPOT
WITH A MAXIMUM TEMPERATURE OF ONLY 55 ON 7/27. MEAN DAILY
TEMPERATURES ON 7/27 WERE AROUND 10 TO AS MUCH AS 15 DEGREES BELOW
NORMAL.

A SERIES OF DISTURBANCES DROPPING SOUTHEASTWARD FROM CANADA IN THE
NORTHWEST FLOW AROUND THE EASTERN NORTH AMERICAN TROUGH BROUGHT SOME
SHOWERS AND EVEN A THUNDERSTORM OR TWO ON 7/28 THROUGH 7/30...MAINLY
DURING THE AFTERNOON AND EARLY EVENING WHEN DAYTIME HEATING RESULTED
IN GREATER DESTABILIZATION. THE SHOWERS WERE MOST WIDESPREAD
IN THE AFTERNOON ON 7/30...BUT EVEN THEN MOST PLACES SAW NO MORE
THAN 0.25 INCH OF RAIN ON EACH OF THESE DAYS. WITH COOL CANADIAN AIR
DOMINATING...MEAN DAILY TEMPERATURES ON 7/28 THROUGH 7/30 RAN FROM
ABOUT 5 TO 10 DEGREES BELOW NORMAL. A STRONGER HIGH PRESSURE SYSTEM
FOLLOWED THE LAST DISTURBANCE...RESULTING IN PARTLY CLOUDY AND
PLEASANT WEATHER ON 7/31...WHEN THE MEAN DAILY TEMPERATURE WAS A
COUPLE OF DEGREES BELOW NORMAL.

                        SEPTEMBER 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
SEPTEMBER 2014.

                       SEPTEMBER CLIMATOLOGY

AVERAGE TEMPERATURES IN SEPTEMBER BEGIN TO FALL SHARPLY...ABOUT 8 TO
9 DEGREES LOWER THAN IN AUGUST...AS SUMMER TRANSITIONS TO AUTUMN AND
DAYLIGHT GROWS SHORTER. THE AUTUMNAL EQUINOX THIS YEAR IS AT 1029 PM
EDT ON 9/22. POSSIBLE SUNSHINE IN SEPTEMBER DECLINES FROM 800
MINUTES ON 9/1 TO 706 MINUTES ON 9/30...A DECREASE OF 3 TO 4 MINUTES
EACH DAY.

ALTHOUGH THE DAYS GROW SHORTER DURING THE NINTH MONTH...MID SUMMER
LIKE WARMTH CAN STILL GRIP UPPER MICHIGAN DURING SEPTEMBER. ON
9/12/98...RESIDENTS OF IRON MOUNTAIN SIZZLED IN 98-DEGREE HEAT. BOTH
IRON MOUNTAIN AND IRONWOOD RECORDED HIGH TEMPERATURES ABOVE 90 FIVE
DAYS IN A ROW DURING A TORRID MID SEPTEMBER HEATWAVE BETWEEN 9/8 AND
9/12 IN 1931. WITH TEMPERATURES AVERAGING 7 TO 8 DEGREES ABOVE
NORMAL...SEPTEMBER 1931 GOES DOWN IN THE RECORD BOOKS AS THE WARMEST
SEPTEMBER EVER OBSERVED AT IRON MOUNTAIN AND IRONWOOD. MORE RECENTLY
IN 2002...MANY PLACES BAKED IN 90-DEGREE HEAT FOR THREE DAYS IN A
ROW ON 9/7 THROUGH 9/9.

MONTHLY TEMPERATURES RAN 3 TO 8 DEGREES ABOVE NORMAL IN SEPTEMBER
2004...WHICH IS THE WARMEST SEPTEMBER SINCE RECORDS BEGAN AT
ONTONAGON AND THE MARQUETTE NWS. THE MONTHLY AVERAGE TEMPERATURE OF
61.8 AT THE MARQUETTE NWS WAS ONLY A TENTH OF A DEGREE LOWER THAN
THE 61.9 READING OBSERVED IN JULY 2004. SEPTEMBER 2004 ALSO RANKS IN
THE LIST OF TOP TEN WARMEST AT IRON MOUNTAIN...MARQUETTE
CITY...NEWBERRY...MUNISING...AND IRONWOOD. SEPTEMBER 2009 WAS ALSO
QUITE BALMY WITH MONTHLY AVERAGE TEMPERATURES 4 TO 6 DEGREES ABOVE
THE 1971-2000 MEAN. THAT MONTH WAS AMONG THE TOP 10 WARMEST
SEPTEMBERS AT MOST LOCATIONS IN UPPER MICHIGAN.

BUT WINTER OFTEN MAKES ITS FIRST RETURN BY LATE IN THE MONTH. THE
GROWING SEASON ENDS EVERYWHERE EXCEPT ALONG THE WARMER GREAT LAKES
SHORES DURING SEPTEMBER WITH AN INCREASED PROBABILITY OF KILLING
FROST. RECORD LOW TEMPERATURES OVER INLAND AREAS FALL INTO THE 20S
DURING THE MONTH AND EVEN INTO THE UPPER TEENS AT MANY LOCATIONS
TOWARD MONTHS END. ON 9/22/95...THE WESTERN UPPER PENINSULA WAS
STRUCK WITH AN EARLY SEASON SNOWSTORM. IRONWOOD PICKED UP 6.5
INCHES...AND HOUGHTON ALSO SAW 3 INCHES OF THE WHITE STUFF THAT DAY.
AT LEAST AN INCH OF SNOW HAS FALLEN ON PORTIONS OF UPPER MICHIGAN
DURING LATE SEPTEMBER IN 1965...1974...1989...AND 1993.

AS THE JET STREAM SINKS FARTHER SOUTH DURING SEPTEMBER AND INTERACTS
WITH FAIRLY WARM AND HUMID AIRMASSES STILL RESIDENT OVER THE UNITED
STATES...AVERAGE MONTHLY PRECIPITATION OVER MUCH OF UPPER MICHIGAN
PEAKS AT A YEARLY MAXIMUM BETWEEN 3.5 AND 4.0 INCHES. ALTHOUGH
CONVECTION OCCURS LESS FREQUENTLY THAN DURING MID SUMMER...
THUNDERSTORMS STILL PRESENT A SEVERE WEATHER AND HEAVY RAIN THREAT.
IRONWOOD WAS INUNDATED WITH 10.74" OF RAIN DURING SEPTEMBER 1926.

                   OUTLOOK FOR FALL AND EARLY WINTER

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING A GREATER THAN
CLIMATOLOGICAL CHANCE OF AN ABOVE NORMAL 3-MONTH AVERAGE TEMPERATURE
BUT EQUAL CHANCES OF ABOVE AND BELOW NORMAL 3-MONTH PRECIPITATION
OVER ALL OF UPPER MICHIGAN IN OCTOBER THROUGH DECEMBER 2014.
