...GREAT LAKES WATER LEVELS REMAIN WELL ABOVE NORMAL IN AUGUST...

GENERALLY ABUNDANT RAINFALL AROUND THE WESTERN GREAT LAKES THROUGH
THE SUMMER ALLOWED WATER LEVELS ON LAKES SUPERIOR, MICHIGAN AND
HURON TO REMAIN NEARLY STEADY IN AUGUST DESPITE INCREASING WATER
TEMPERATURES THAT ENHANCED EVAPORATION. AT THE END OF AUGUST, WATER
LEVELS ON LAKE SUPERIOR WERE 6 TO 7 INCHES ABOVE NORMAL AND WITHIN
AN INCH OF THE LEVEL OBSERVED IN AUGUST 2015. THE LEVEL ON LAKES
MICHIGAN AND HURON WAS 10 TO 11 INCHES ABOVE AVERAGE ON 8/31 AND 3
TO 4 INCHES HIGHER THAN IN AUGUST 2015.

                       AUGUST CLIMATE HIGHLIGHTS

HIGHEST REPORTED TEMPERATURE...93 AT A SPOT ABOUT 10 MILES SOUTH OF
                                MUNISING ON 8/3

LOWEST REPORTED TEMPERATURE...33 AT THE SPOT SOUTH OF MUNISING
                               ON 8/22

HIGHEST AVERAGE TEMPERATURE...70.1 DEGREES AT IRON MOUNTAIN

LOWEST AVERAGE TEMPERATURE...62.7 DEGREES AT HERMAN IN BARAGA COUNTY

HIGHEST MONTHLY PRECIPITATION...7.18 INCHES AT HERMAN

LOWEST MONTHLY PRECIPITATION...2.97 INCHES AT NEWBERRY

WHILE THERE WERE NO EXTENDED, EXCESSIVE HEAT WAVES OVER UPPER
MICHIGAN IN AUGUST, A PREVAILING SOUTHWEST FLOW AROUND HIGH PRESSURE
THAT DOMINATED TO THE SOUTH AND EAST PREVENTED MORE THAN OCCASIONAL
INFLUXES OF COOLER CANADIAN AIR AND THUS BROUGHT WARMER THAN NORMAL
WEATHER MOST OF THE DAYS DURING THE MONTH ACROSS THE U.P. THE RESULT
WAS A MEAN AUGUST TEMPERATURE THAT RAN 2 TO 4 DEGREES ABOVE NORMAL.
MEAN MONTHLY TEMPERATURES BETWEEN ABOUT 63 TO 70 DEGREES WERE NEARLY
THE SAME AS THE JULY AVERAGE TO UP TO 3 DEGREES HIGHER THAN THE
VALUES OBSERVED IN JULY. MAXIMUM TEMPERATURES AT OR ABOVE 90 WERE
INFREQUENT AND OCCURRED ONLY ON 8/3, 8/4 AND 8/10. LIKEWISE, THE
ONLY DAY THAT ANY SPOT ACROSS THE U.P. SAW THE MERCURY FALL INTO THE
30S WAS ON 8/22.

AT MOST PLACES, THE DEPARTURE OF THE MONTHLY AVERAGE MINIMUM
TEMPERATURE FROM NORMAL WAS GREATER THAN THE MAXIMUM TEMPERATURE
ANOMALY. FOR INSTANCE AT NEWBERRY, THE AVERAGE AUGUST LOW
TEMPERATURE OF 59.5 DEGREES WAS 5.5 DEGREES ABOVE NORMAL WHILE THE
77.1 DEGREE MEAN MAXIMUM TEMPERATURE WAS ONLY 1.9 DEGREES ABOVE
AVERAGE.

AT SOME PLACES, AUGUST 2016 GOES DOWN IN THE RECORD BOOKS AS THE
AUGUST WITH THE FEWEST DAYS THAT HAD A MINIMUM TEMPERATURE UNDER 50.
FOR INSTANCE AT MUNISING, THERE WERE NO DAYS WHEN THE LOW
TEMPERATURE FELL UNDER 50, COMPARED TO AN AVERAGE OF NINE DAYS WHEN
READINGS FALL BELOW THAT MARK DURING A TYPICAL AUGUST. AT IRON
MOUNTAIN, THERE WAS ONLY ONE MORNING IN AUGUST WHEN THE THERMOMETER
READ BELOW 50, COMPARED TO AN AVERAGE OF NINE DAYS.

THE PREDOMINATING SOUTHWEST FLOW ALSO TRANSPORTED MOIST AIRMASSES
INTO THE UPPER GREAT LAKES. FREQUENT EPISODES OF SHOWERS AND
THUNDERSTORMS WERE THE RESULT AS PASSING DISTURBANCES INTERACTED
WITH THIS MOISTURE. AS HAS BEEN THE CASE THE LAST COUPLE OF MONTHS,
THE HEAVIEST RAINS TENDED TO FALL OVER THE NORTHWEST HALF OF UPPER
MICHIGAN. MANY PLACES IN THIS AREA PICKED UP 5 OR MORE INCHES OF
RAIN DURING AUGUST, WITH AS MUCH AS 7.18 INCHES FALLING OVER THE
HIGHER TERRAIN OF THE HURON MOUNTAINS AT HERMAN IN BARAGA COUNTY.
THE RAINFALL TOTALS OVER THE NORTHWEST HALF WERE AS MUCH AS 150-175
PERCENT OF THE AVERAGE AUGUST PRECIPITATION AT THESE SPOTS. AREAS
ACROSS EASTERN UPPER MICHIGAN SAW THE LEAST RAIN. THE 2.97 INCHES
THAT FELL AT NEWBERRY IS ABOUT 90 PERCENT OF THE TYPICAL AUGUST
RAINFALL THERE.

THERE WERE TWO PERIODS IN AUGUST THAT FEATURED AT LEAST SOME LOCALLY
HEAVY RAINFALL. A COOL FRONT SAGGING SOUTH INTO THE UPPER GREAT
LAKES ON 8/10 STALLED OVER SOUTH CENTRAL UPPER MICHIGAN LATE IN THE
DAY. AS AN UPPER DISTURBANCE MOVED EAST OVER THIS BOUNDARY AND
INTERACTED WITH THE WARM AND HUMID AIRMASS JUST TO THE SOUTH,
SHOWERS AND SOME THUNDERSTORMS WITH HEAVY RAIN IMPACTED PORTIONS OF
MAINLY THE WESTERN AND SOUTH CENTRAL PORTIONS OF THE U.P. INTO 8/11.
MANY PLACES IN THIS AREA PICKED UP AN INCH OR MORE OF RAIN DURING
THIS TIME. THE HEAVIEST SHOWERS DROPPED TORRENTIAL RAINS THAT
REACHED UP TO 4.88 INCHES NEAR ENSIGN IN DELTA COUNTY...4.34 INCHES
AT ATLANTIC MINE IN HOUGHTON COUNTY...4.17 INCHES NEAR REDRIDGE IN
HOUGHTON COUNTY AND 3.92 INCHES AT JACOBSVILLE IN HOUGHTON COUNTY.
THESE HEAVY RAINS CAUSED SOME FLASH FLOODING THAT WASHED OUT ROADS
IN HOUGHTON COUNTY NEAR HANCOCK. THERE WAS ALSO AN EF-1 TORNADO IN
MENOMINEE COUNTY NEAR HERMANSVILLE IN THE AFTERNOON ON 8/11.
FORTUNATELY, THIS TORNADO TOUCHED DOWN IN AN UNPOPULATED AREA AND
CAUSED RELATIVELY LITTLE DAMAGE.

THERE WAS A MORE WIDESPREAD HEAVY RAIN ON 8/19 INTO EARLY 8/21 AS
ANOTHER UPPER DISTURBANCE APPROACHING FROM THE NORTHERN PLAINS
CAUSED A LOW PRESSURE SYSTEM TO DEVELOP OVER IOWA AND THEN MOVE
NORTHEAST ALONG A STATIONARY FRONT EXTENDING INTO THE UPPER LAKES. A
WARM AND HUMID AIRMASS JUST TO THE SOUTH OF THE FRONT PROVIDED THE
MOISTURE TO SUPPORT HEAVY RAINS ACROSS UPPER MICHIGAN. MOST PLACES
PICKED UP AT LEAST 2 INCHES OF RAIN BETWEEN EARLY ON 8/19 AND
DAYBREAK ON 8/21. HERMAN OVER THE HIGHER TERRAIN OF THE HURON
MOUNTAINS IN BARAGA COUNTY REPORTED THE MOST PRECIPITATION--AN
IMPRESSIVE 4.26 INCHES. OTHER SIGNIFICANT REPORTS INCLUDE 3.86
INCHES AT PAULDING IN ONTONAGON COUNTY, 3.68 INCHES AT BERGLAND DAM
IN ONTONAGON COUNTY AND WATERSMEET IN GOGEBIC COUNTY, AND 3.59
INCHES NEAR GERMFASK IN SCHOOLCRAFT COUNTY. NORTH WINDS GUSTING AS
HIGH AS 40 TO 50 MPH NEAR LAKE SUPERIOR DURING THE NIGHT ON 8/20-
8/21 IN THE WAKE OF THE PASSING LOW PRESSURE SYSTEM ALSO CAUSED HIGH
WAVES AS WELL AS SOME LAKESHORE FLOODING AND EROSION AT EXPOSED
LOCATIONS BEFORE THE WELCOME ARRIVAL OF A HIGH PRESSURE RIDGE
BROUGHT MORE TRANQUIL WEATHER TO THE AREA LATER ON 8/21.

                        AUGUST WEATHER SUMMARY

HIGH PRESSURE CONTINUED TO DOMINATE THE WEATHER OVER UPPER MICHIGAN
AT THE BEGINNING OF AUGUST, BRINGING DRY AND SEASONABLE WEATHER ON
8/1. ON 8/2 INTO 8/3, A WEAK COOL FRONT MOVING INTO THE UPPER GREAT
LAKES INTERACTED WITH AN INCREASINGLY WARM AND MORE HUMID AIRMASS TO
BRING SCATTERED SHOWERS AND THUNDERSTORMS TO THE AREA. ALTHOUGH MANY
PLACES SAW LITTLE IF ANY RAIN DURING THIS TIME, WATERSMEET IN
GOGEBIC COUNTY AND STAMBAUGH IN IRON COUNTY PICKED UP AS MUCH AS
0.94 INCH OF RAIN. THERE WAS ALSO SOME LOCALLY HEAVY RAIN UNDER A
SLOW MOVING THUNDERSTORM OVER FAR SOUTHERN MENOMINEE COUNTY DURING
THE AFTERNOON ON 8/3. HIGH TEMPERATURES ON 8/3 CLIMBED ABOVE 90 AT
SEVERAL LOCATIONS AND REACHED AS HIGH AS 93 AT SPOT JUST SOUTH OF
MUNISING. SINCE THE COOL FRONT DISSIPATED OVER THE AREA, THE
OVERNIGHT ON 8/3-8/4 WAS QUITE WARM. THE THERMOMETER FELL NO LOWER
THAN 70 AT A FEW LOCATIONS NEAR THE GREAT LAKES, INCLUDING AN
UNCOMFORTABLE LOW OF 72 AT ESCANABA AT SUNRISE ON 8/4. MEAN DAILY
TEMPERATURES WERE 5 TO 10 DEGREES ABOVE NORMAL ON 8/2 AND THEN
AROUND 10 DEGREES ABOVE AVERAGE ON 8/3.

A STRONGER COLD FRONT APPROACHED THE AREA ON 8/4 ACCOMPANIED BY MORE
SCATTERED SHOWERS AND STORMS, BUT NO PLACE REPORTED MORE THAN 0.10
TO 0.25 INCH OF RAIN. AHEAD OF THIS FRONT, THE AFTERNOON ON 8/4 WAS
ANOTHER WARM AND HUMID ONE WITH TEMPERATURES PEAKING AS HIGH AS 90
AT MARQUETTE. DURING THE NIGHT ON 8/4-8/5, THE COLD FRONT SWEPT
ACROSS THE AREA ACCOMPANIED ONLY BY ISOLATED SHOWERS. WEST WINDS
OVER THE KEWEENAW GUSTED AS HIGH AS 40 MPH BEHIND THIS FRONTAL
PASSAGE AND HELPED TO DRIVE A COOLER AND LESS HUMID AIRMASS INTO THE
UPPER LAKES AHEAD OF CANADIAN HIGH PRESSURE. THIS HIGH THEN BROUGHT
SEASONABLY COOL CONDITIONS TO THE U.P. ON 8/5 THROUGH 8/8. ALTHOUGH
THERE WERE SOME INSTABILITY CLOUDS AND EVEN A FEW SHOWERS ON 8/5,
THE WEATHER ON 8/6 THROUGH 8/8 FEATURED MOSTLY CLEAR SKIES.

AFTER THE HIGH MOVED TO THE EAST ON 8/9, A SOUTHWEST WIND THAT
GUSTED UP TO 30 MPH BROUGHT A RETURN OF WARMER AND MORE HUMID AIR,
LIFTING THE DAILY AVERAGE TEMPERATURE UP TO 10 DEGREES ABOVE NORMAL
ON 8/9. MORE CLOUDS ARRIVED AHEAD OF A SLOWLY APPROACHING COOL
FRONT, AND THERE WERE ALSO A FEW SHOWERS AND THUNDERSTORMS OVER THE
NORTHWEST DURING THE EVENING AS THIS FRONT ARRIVED. THIS FRONT
STALLED OVER SOUTH CENTRAL UPPER MICHIGAN LATE IN THE DAY ON 8/10,
BUT HIGH TEMPERATURES STILL REACHED 91 AT IRON MOUNTAIN. AS AN UPPER
DISTURBANCE MOVED EAST OVER THIS BOUNDARY AND INTERACTED WITH THE
WARM AND HUMID AIRMASS JUST TO THE SOUTH, SHOWERS AND SOME
THUNDERSTORMS WITH HEAVY RAIN IMPACTED PORTIONS OF MAINLY THE
WESTERN AND SOUTH CENTRAL PORTIONS OF THE U.P. INTO 8/11. MANY
PLACES IN THIS AREA PICKED UP AN INCH OR MORE OF RAIN DURING THIS
TIME. THE HEAVIEST SHOWERS DROPPED TORRENTIAL RAINS THAT REACHED UP
TO 4.88 INCHES NEAR ENSIGN IN DELTA COUNTY, 4.34 INCHES AT ATLANTIC
MINE IN HOUGHTON COUNTY, 4.17 INCHES NEAR REDRIDGE IN HOUGHTON
COUNTY AND 3.92 INCHES AT JACOBSVILLE IN HOUGHTON COUNTY. THESE
HEAVY RAINS CAUSED SOME FLASH FLOODING THAT WASHED OUT ROADS IN
HOUGHTON COUNTY NEAR HANCOCK.  THERE WAS ALSO AN EF-1 TORNADO IN
MENOMINEE COUNTY NEAR HERMANSVILLE IN THE AFTERNOON ON 8/11.
FORTUNATELY, THIS TORNADO TOUCHED DOWN IN AN UNPOPULATED AREA AND
CAUSED RELATIVELY LITTLE DAMAGE. WITH THE WARM AND HUMID AIRMASS
STILL IN PLACE OVER THE SOUTH, LOW TEMPERATURES ON 8/11 HELD ABOVE
70 AT SOME PLACES, INCLUDING AN UNCOMFORTABLE 73 AT FAIRPORT IN
DELTA COUNTY. MEAN DAILY TEMPERATURES ON 8/10 AND 8/11 RAN FROM NEAR
NORMAL OVER THE NORTH ON THE COOL SIDE OF THE STATIONARY FRONT TO
AROUND 10 DEGREES ABOVE NORMAL ACROSS THE SOUTH.

SINCE ONLY A WEAK RIDGE OF HIGH PRESSURE FOLLOWED ONCE THE FRONT
FINALLY CLEARED THE UPPER LAKES EARLY ON 8/12, A GOOD DEAL OF CLOUD
COVER LINGERED ON 8/12 AND 8/13 ALONG WITH SOME ISOLATED LIGHT
SHOWERS. THERE WAS ALSO SOME FOG DURING THE EARLY MORNINGS ON 8/12,
8/13 AND 8/14 THAT BECAME LOCALLY DENSE. THE COMBINATION OF THE
COOLER AIR AND LINGERING CLOUD COVER BEHIND THE FRONT HELD MEAN
DAILY TEMPERATURES TO WITHIN A FEW DEGREES OF NORMAL ON 8/12 AND
8/13. AN APPROACHING STRONGER UPPER DISTURBANCE CAUSED SOME SHOWERS
AND A FEW THUNDERSTORMS OVER MAINLY THE CENTRAL COUNTIES ON 8/14.
SOME LOCATIONS IN THIS AREA PICKED UP 0.25 TO 0.50 INCH OF RAIN, BUT
AS MUCH AS 1.27 INCHES FELL NEAR GLADSTONE IN DELTA COUNTY UNDER
SOME LOCALLY HEAVY DOWNPOURS. MOSTLY CLEAR SKIES RETURNED DURING THE
NIGHT ON 8/14-8/15 AND PERSISTED INTO 8/16 AS A HIGH PRESSURE RIDGE
TRAILING THE DEPARTING DISTURBANCE PASSED THROUGH THE UPPER LAKES.
THERE WAS SOME FOG DURING THE EARLY MORNINGS ON 8/15 AND 8/16. NEAR
NORMAL TEMPERATURES WERE THE RULE ON 8/14 AND 8/15.

ANOTHER PASSING DISTURBANCE BROUGHT SCATTERED SHOWERS AND A FEW
THUNDERSTORMS ON 8/16 INTO 8/17 AWAY FROM THE KEWEENAW. ALTHOUGH
MOST PLACES SAW LESS THAN 0.10 INCH OF RAIN, AN AREA OVER THE SOUTH
CENTRAL SAW 0.25 INCH OR MORE, INCLUDING AS MUCH AS 0.47 INCH AT
BARK RIVER IN DELTA COUNTY AND 0.46 NEAR ARNOLD IN SOUTHERN
MARQUETTE COUNTY. DRIER WEATHER RETURNED ON 8/17 AND PERSISTED
THROUGH 8/18 AS ANOTHER HIGH PRESSURE TRACKED OVER THE U.P. THE
THERMOMETER AVERAGED AROUND 5 DEGREES ABOVE NORMAL ON 8/16 AND 8/17
BUT THEN 5 TO 10 DEGREES ABOVE AVERAGE ON 8/18.

THE SOUTHWEST FLOW OF AIR BETWEEN THE DEPARTING HIGH PRESSURE AND A
VIGOROUS UPPER DISTURBANCE AND COLD FRONT MOVING INTO THE NORTHERN
PLAINS ADVECTED MORE HUMID AIR INTO THE UPPER LAKES DURING THE NIGHT
ON 8/18-8/19, RESULTING IN MORE CLOUDS AND SOME SCATTERED SHOWERS
AND THUNDERSTORMS IN THE EARLY MORNING ON 8/19. A MORE WIDESPREAD
HEAVY RAIN THEN OCCURRED ON 8/19 INTO EARLY 8/21 AS THE DISTURBANCE
APPROACHING FROM THE NORTHERN PLAINS CAUSED A LOW PRESSURE SYSTEM TO
DEVELOP OVER IOWA AND THEN MOVE NORTHEAST ALONG THE STALLED FRONT
EXTENDING INTO THE UPPER LAKES. THE LINGERING WARM AND HUMID AIRMASS
JUST TO THE SOUTH OF THE FRONT PROVIDED THE MOISTURE TO SUPPORT
HEAVY RAINS ACROSS UPPER MICHIGAN. MOST PLACES PICKED UP AT LEAST 2
INCHES OF RAIN BETWEEN EARLY ON 8/19 AND DAYBREAK ON 8/21. HERMAN
OVER THE HIGHER TERRAIN OF THE HURON MOUNTAINS IN BARAGA COUNTY
REPORTED THE MOST PRECIPITATION--AN IMPRESSIVE 4.26 INCHES. OTHER
SIGNIFICANT REPORTS INCLUDE 3.86 INCHES AT PAULDING IN ONTONAGON
COUNTY, 3.68 INCHES AT BERGLAND DAM IN ONTONAGON COUNTY AND
WATERSMEET IN GOGEBIC COUNTY, AND 3.59 INCHES NEAR GERMFASK IN
SCHOOLCRAFT COUNTY. NORTH WINDS GUSTING AS HIGH AS 40 TO 50 MPH NEAR
LAKE SUPERIOR DURING THE NIGHT ON 8/20-8/21 IN THE WAKE OF THE
PASSING LOW PRESSURE SYSTEM ALSO CAUSED HIGH WAVES AS WELL AS SOME
LAKESHORE FLOODING AND EROSION AT EXPOSED LOCATIONS BEFORE THE
WELCOME ARRIVAL OF A HIGH PRESSURE RIDGE BROUGHT MORE TRANQUIL
WEATHER TO THE AREA LATER ON 8/21. MEAN DAILY TEMPERATURES RUNNING
UP TO 5 DEGREES ABOVE AVERAGE ON 8/19 FELL OFF TO 5 TO 10 DEGREES
BELOW NORMAL ON 8/20 AND 8/21 UNDER THE EXTENSIVE CLOUD COVER AND
RAIN. THE AFTERNOONS ON 8/20 AND 8/21 WERE PARTICULARLY COOL,
FEATURING HIGH TEMPERATURES MAINLY IN THE 60S. SOME SPOTS OVER THE
HIGHER TERRAIN NEAR LAKE SUPERIOR SAW THE MERCURY PEAK ONLY IN THE
UPPER 50S ON 8/20, INCLUDING HERMAN OVER THE HIGHER TERRAIN OF THE
HURON MOUNTAINS IN BARAGA COUNTY WHERE THE HIGHEST READING WAS 57.

THE HIGH PRESSURE RIDGE TRAILING THE EXITING LOW PRESSURE SYSTEM
BROUGHT CLEARING DURING THE NIGHT ON 8/21-8/22. THE EARLY MORNING ON
8/22 WAS A CHILLY ONE WITH LIGHT WINDS AND MOSTLY CLEAR SKIES UNDER
THE HIGH PRESSURE RIDGE. THE MERCURY FELL INTO THE 30S AT MANY OF
THE INTERIOR COOL SPOTS, INCLUDING A READING AS LOW AS 33 AT A SITE
JUST TO THE SOUTH OF MUNISING. BUT SINCE THE CENTER OF HIGH PRESSURE
PASSED TO THE SOUTH THROUGH THE OHIO RIVER VALLEY, A WARM AND MORE
HUMID SOUTHWEST WIND THAT GUSTED TO 25 MPH QUICKLY DEVELOPED ON
8/22. AS A WARM FRONT APPROACHED DURING THE NIGHT ON 8/22-8/23, A
BAND OF SHOWERS AND THUNDERSTORMS IMPACTED MAINLY THE SOUTHWEST HALF
OF UPPER MICHIGAN. SOME OF THE STRONGER STORMS DROPPED DIME- TO
NICKLE-SIZED HAIL IN GOGEBIC AND ONTONAGON COUNTIES. SOME PLACES
OVER THE SOUTHWEST ALSO PICKED UP 0.25 INCH OF RAIN OR MORE.
GLADSTONE LED REPORTING STATIONS AGAIN WITH 0.73 INCH OF RAIN.
FOLLOWING THE WARM FRONTAL PASSAGE, THE DAY ON 8/23 TURNED MOSTLY
SUNNY, WARM AND BREEZY WITH SOUTHWEST GUSTS UP TO 25 MPH. THE DAY ON
8/22 WAS SEASONABLY CHILLY, BUT THE MEAN DAILY TEMPERATURE ON 8/23
ROSE TO 5 TO 10 DEGREES ABOVE AVERAGE.

CLOUDS BEGAN TO INCREASE AGAIN DURING THE NIGHT ON 8/23-8/24 AHEAD
OF A COLD FRONT MOVING INTO MINNESOTA. AS AN UPPER DISTURBANCE
APPROACHED FROM THE SOUTHWEST, MORE SHOWERS DEVELOPED BY SUNRISE ON
8/24 OVER ALL BUT THE KEWEENAW AND CONTINUED TO THE EAST THROUGH THE
MORNING ON 8/24 BEFORE DIMINISHING IN THE AFTERNOON. SOME PLACES
OVER THE SOUTHEAST HALF LOGGED AROUND 0.25 INCH OF RAIN. MANISTIQUE
REPORTED THE MOST PRECIPITATION WITH 0.42 INCH. THE APPROACHING COLD
FRONT THEN PASSED ACROSS UPPER MICHIGAN DURING THE NIGHT ON 8/24-
8/25, ACCOMPANIED ONLY BY SOME CLOUDS. BEHIND THE FRONT ON 8/25,
SKIES WERE SUNNY TO PARTLY CLOUDY, AND WEST WINDS GUSTED AS HIGH AS
35 TO 40 MPH OVER THE KEWEENAW. THE THERMOMETER AVERAGED ABOUT 5
DEGREES ABOVE NORMAL ON BOTH 8/24 AND 8/25. MORE CLOUDS ALONG WITH
SOME COOLER AIR AND SOME SHOWERS ROLLED INTO THE NORTHWEST DURING THE
EARLY MORNING ON 8/26 AS ANOTHER LOW PRESSURE TROUGH CLOSED IN ON THE
AREA. THESE SHOWERS PERSISTED OVER MAINLY THE NORTHERN TIER ON 8/26
AS THE WEAK TROUGH PASSED BY. LINGERING CLOUDS WITHIN THE COOL
AIRMASS CAUSED THE MEAN DAILY TEMPERATURE TO DIP TO AROUND 5 DEGREES
BELOW NORMAL ON 8/26.

SKIES CLEARED BRIEFLY DURING THE EVENING ON 8/26 AS A RIDGE OF
HIGH PRESSURE PASSED, BUT THEN CLOUDS INCREASED AGAIN AHEAD OF
ANOTHER DISTURBANCE MOVING EAST THROUGH THE NORTHERN PLAINS.
ALTHOUGH SHOWERS ASSOCIATED WITH THIS DISTURBANCE AND A WEAK
LOW PRESSURE MOVING THROUGH THE CENTRAL GREAT LAKES IMPACTED
MAINLY THE SOUTHEAST HALF OF UPPER MICHIGAN THROUGH 8/27, SKIES
REMAINED MOSTLY CLOUDY OVER THE ENTIRE AREA INTO THE MORNING ON
8/28, WHEN TRAILING HIGH PRESSURE BROUGHT A RETURN OF MORE SUNSHINE.
RAINFALL ON 8/27 VARIED FROM NO MORE THAN 0.10 INCH OVER THE
NORTHWEST HALF TO UP TO ABOUT 0.25 INCH OVER THE SOUTHEAST. NEWBERRY
MEASURED THE MOST WITH 0.26 INCH. TEMPERATURES ON 8/27 AND 8/28 WERE
NEAR THE LATE AUGUST AVERAGES.

SOME FOG DEVELOPED DURING THE NIGHT ON 8/28-8/29 BEFORE MORE CLOUDS
RETURNED OVER THE WEST BY THE EARLY MORNING ON 8/29 IN ADVANCE OF A
COLD FRONT MOVING TOWARD MINNESOTA. SCATTERED SHOWERS AND A FEW
THUNDERSTORMS WELL AHEAD OF THIS BOUNDARY IMPACTED WESTERN UPPER
MICHIGAN DURING THE MORNING ON 8/29 BEFORE DISSIPATING. BUT AS THE
STEADY SOUTHWEST WIND BETWEEN THE APPROACHING FRONT AND THE
DEPARTING HIGH PRESSURE DREW MORE HUMID AIR INTO THE UPPER LAKES,
MORE NUMEROUS SHOWERS AND STORMS DEVELOPED OVER MAINLY THE SOUTHWEST
HALF DURING THE NIGHT ON 8/29-8/30 AS THE FRONT REACHED THE AREA AT
DAYBREAK ON 8/30. RAINFALL AT MOST PLACES WAS UNDER 0.25 INCH, BUT
UP TO 0.83 INCH FELL AT KENTON IN FAR SOUTHERN HOUGHTON COUNTY. MORE
CLOUDS AND SOME ISOLATED SHOWERS LINGERED ON 8/30 OVER THE SOUTH
CENTRAL, BUT SKIES TURNED MOSTLY SUNNY OVER THE NORTHWEST HALF AS
DRIER AIR FOLLOWED THE FRONTAL PASSAGE. AS CANADIAN HIGH PRESSURE
BUILT TOWARD THE WESTERN GREAT LAKES, MOSTLY CLEAR AND COOLER
WEATHER THEN DOMINATED DURING THE NIGHT ON 8/30-8/31. MORE CLOUDS
AND A FEW SHOWERS RETURNED ON 8/31 AS AN UPPER DISTURBANCE AND LOW
PRESSURE TROUGH PASSED OVER THE UPPER LAKES. SEVERAL WATERSPOUTS
EVEN DEVELOPED OVER SOUTH CENTRAL LAKE SUPERIOR NEAR MARQUETTE UNDER
SOME OF THE HEAVIER SHOWERS.

                          OCTOBER 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 MONTHLY PRECIPITATION
ACROSS ALL OF UPPER MICHIGAN IN OCTOBER 2016.

                         OCTOBER CLIMATOLOGY

AVERAGE TEMPERATURES IN OCTOBER CONTINUE THEIR DOWNWARD SPIRAL AS
THE SUN STAYS UP LESS AND LESS EACH DAY. THE OCTOBER MEAN
TEMPERATURE ACROSS UPPER MICHIGAN IS ABOUT TEN DEGREES LOWER THAN IN
SEPTEMBER AT MOST PLACES. POSSIBLE DAILY SUNSHINE DECREASES ABOUT 3
OR 4 MINUTES EVERY DAY DURING THE TENTH MONTH FROM 703 MINUTES ON
10/1 TO 607 MINUTES ON HALLOWEEN.

ALTHOUGH AVERAGE TEMPERATURES DECREASE DURING OCTOBER...RECORD HIGH
TEMPERATURES AT MANY PLACES IN UPPER MICHIGAN ARE STILL IN THE 80S
DURING THE FIRST WEEK OF THE MONTH. IN FACT...RESIDENTS OF IRON
MOUNTAIN BASKED IN A SUMMER-LIKE HIGH OF 88 ON 10/3/92. DOWNTOWN
MARQUETTE ENJOYED A TASTE OF SUMMER EVEN AS LATE AS 10/18 IN 1950...
WHEN THE MERCURY REACHED A BALMY 86 DEGREES.

BUT BY THE END OF OCTOBER...THE ICY HAND OF WINTER USUALLY BEGINS TO
GRIP UPPER MICHIGAN HARDER AND HARDER. RECORD LOW TEMPERATURES AT
MONTHS END FALL INTO THE TEENS EVERYWHERE AND EVEN AS LOW AS THE
SINGLE NUMBERS ABOVE ZERO AWAY FROM THE WARMING INFLUENCE OF LAKE
SUPERIOR. ON 10/30/1925...IRONWOOD RECORDED A LOW OF 2 DEGREES ABOVE
ZERO. OCTOBER 2002 WAS THE COLDEST OCTOBER ON RECORD AT THE
MARQUETTE NWS...AND AMONG THE TOP TEN COLDEST AT IRONWOOD AND IRON
MOUNTAIN. MONTHLY TEMPERATURES AVERAGED 4 TO 6 DEGREES BELOW NORMAL
ACROSS UPPER MICHIGAN. OCTOBER 2009 WAS ALSO QUITE CHILLY WITH AN
AVERAGE MONTHLY TEMPERATURE 3 TO 5 DEGREES BELOW THE MEAN. MUNISING
REPORTED THE COLDEST OCTOBER ON RECORD IN 2009...AND MANY PLACES
EXPERIENCED A TOP FIVE OR TEN COLDEST TENTH MONTH.

EVEN THOUGH AVERAGE PRECIPITATION IN OCTOBER IS LOWER THAN IN
SEPTEMBER AT MOST SPOTS...THE RESIDUAL WARMTH OF LAKE SUPERIOR
USUALLY CAUSES INCREASED LAKE EFFECT RAIN AND SNOW SHOWER ACTIVITY
DURING THE TENTH MONTH. MORE NUMEROUS ARCTIC AIR MASSES PLUNGING
SOUTH FROM CANADA ARE DESTABILIZED AS THEY CROSS THE RELATIVELY WARM
WATER...RESULTING IN THE INCREASED CONVECTIVE ACTIVITY. IF THE AIR
IS COLD ENOUGH...HEAVY SNOW CAN FALL...ESPECIALLY OVER HIGHER
TERRAIN JUST DOWNWIND OF LAKE SUPERIOR. BETWEEN 10/11 AND 10/14 IN
2006...AN UNUSUALLY EARLY WINTER STORM BLASTED THE HIGHER TERRAIN OF
THE WEST HALF OF UPPER MICHIGAN WITH 20 OR MORE INCHES OF SNOW...
INCLUDING AS MUCH AS 26.6 INCHES AT TWIN LAKES IN HOUGHTON COUNTY.
IN OCTOBER 1967...ALMOST 27 INCHES OF SNOW WHITENED IRONWOOD...
INCLUDING 15 INCHES ON 10/25/67. HEAVY SNOW CAN FALL EVEN EARLIER IN
THE MONTH. ON 10/6 TO 10/8 IN 2000...UP TO A FOOT OF SNOW SMOTHERED
THE HIGHER TERRAIN OF NORTH CENTRAL UPPER MICHIGAN. BUT DURING WARM
OCTOBERS...LITTLE OR NO SNOW CAN FALL AS WELL. THE MARQUETTE NWS SAW
NO SNOW AT ALL IN OCTOBER 1971...AS DID THE HOUGHTON COUNTY AIRPORT
IN 1986.

THE SAME SURFACE HEATING AND DESTABILIZATION OF COLD AIRMASSES THAT
CAUSES LAKE EFFECT SNOW ALSO RESULTS IN INCREASED WINDINESS OVER
LAKE SUPERIOR. THE GALES OF NOVEMBER OFTEN DO COME EARLY DURING
OCTOBER.

                 OUTLOOK FOR LATE FALL INTO WINTER

THE CPC IS FORECASTING AN EQUAL CHANCE OF AN ABOVE AND BELOW NORMAL
3-MONTH AVERAGE TEMPERATURE AND 3-MONTH PRECIPITATION OVER ALL OF
UPPER MICHIGAN IN NOVEMBER 2016 THROUGH JANUARY 2017.
