...GREAT LAKES WATER LEVELS RISE SLOWLY AND REMAIN WELL ABOVE NORMAL
IN JUNE...

DESPITE PERIODS OF DRY WEATHER IN RECENT MONTHS, GREAT LAKES WATER
LEVELS CONTINUED TO RISE SLOWLY DURING JUNE DUE TO RUNOFF FROM
EPISODES OF HEAVY PRECIPITATION THAT HAVE ALSO IMPACTED THE AREA. AT
THE END OF JUNE, WATER LEVELS ON LAKE SUPERIOR WERE 8 TO 9 INCHES
ABOVE NORMAL AND WITHIN AN INCH OF THE LEVEL OBSERVED IN JUNE 2015.
THE LEVEL ON LAKES MICHIGAN AND HURON WAS 11 TO 12 INCHES ABOVE
AVERAGE ON 6/29 AND ABOUT 6 INCHES HIGHER THAN IN JUNE 2015.

LOWEST REPORTED TEMPERATURE...27 NEAR COVINGTON IN BARAGA COUNTY
                               ON 6/8 AND NEAR NEWBERRY ON 6/9

HIGHEST AVERAGE TEMPERATURE...63.5 DEGREES AT FORD AIRPORT NEAR IRON
                               MOUNTAIN

LOWEST AVERAGE TEMPERATURE...56.9 DEGREES AT COPPER HARBOR

HIGHEST MONTHLY PRECIPITATION...6.42 INCHES AT IRONWOOD

LOWEST MONTHLY PRECIPITATION...2.34 INCHES AT CHATHAM IN ALGER COUNTY

THE WEATHER PATTERN ACROSS NORTH AMERICA WAS A CHANGEABLE ONE IN
JUNE 2016, RESULTING IN VARIABLE TEMPERATURES AS WELL AS ABOVE
NORMAL PRECIPITATION AT MOST PLACES, ESPECIALLY ACROSS THE NORTHWEST
HALF OF UPPER MICHIGAN. OVERALL, THE TEMPERATURE VARIATIONS TENDED
TO BALANCE OUT, SO THE MEAN MONTHLY TEMPERATURE BETWEEN ABOUT 57 AND
63 DEGREES ENDED UP WITHIN A DEGREE OF THE JUNE NORMAL OVER ALL OF
UPPER MICHIGAN. THESE MEAN TEMPERATURES WERE 6 TO 10 DEGREES HIGHER
THAN THE MAY AVERAGES. THE COOLEST PERIOD WAS 6/6 TO 6/9 AND
FEATURED SOME LOW TEMPERATURES IN THE 20S ON 6/8 AND 6/9. DURING THE
WARMEST TIME UNDER AN UPPER RIDGE ON 6/17 INTO 6/19, THE THERMOMETER
TOPPED OUT IN THE 90S AT SOME LOCATIONS.

EVEN THOUGH THERE WERE VERY DRY PERIODS WHEN HIGH PRESSURE
DOMINATED, SOME MODERATE TO HEAVY RAINS FELL DURING THE TIMES UPPER
TROUGHING PREVAILED AND ALLOWED STRONGER DISTURBANCES TO INTERACT
WITH THE MOIST AIRMASSES THAT FLOWED INTO THE GREAT LAKES. THESE
DISTURBANCES HAD MORE OF AN IMPACT OVER THE NORTHWEST HALF OF THE
UPPER PENINSULA, WHERE JUNE RAINFALL EXCEEDED 4 INCHES AT SOME
LOCATIONS AND EVEN REACHED 6.42 INCHES AT IRONWOOD. THERE WAS
ANOTHER STRIPE OF HIGHER PRECIPITATION OVER THE FAR SOUTH CENTRAL.
JUNE RAINFALL AT MENOMINEE WAS 6.40 INCHES. THESE TOTALS ARE ABOUT
175 PERCENT OF THE JUNE NORMALS. THE LEAST RAIN AROUND 2.50 TO
3.00 INCHES FELL ALONG A LINE FROM CRYSTAL FALLS TO GWINN IN
MARQUETTE COUNTY, MUNISING AND NEWBERRY. THE LOWEST MONTHLY
PRECIPITATION REPORT OF 2.34 INCHES AT CHATHAM IN ALGER COUNTY IS
ABOUT 75 PERCENT OF THE NORMAL JUNE RAINFALL FOR THAT LOCATION.

THE FIRST HALF OF JUNE FEATURED AN ACTIVE WEATHER PATTERN WITH
FREQUENT SHOWERS. WIDESPREAD SHOWERS OCCURRED ON 6/1, 6/4, 6/6,
6/10, AND 6/15. ON 6/1, A COLD FRONT ATTENDANT TO LOW PRESSURE
MOVING THROUGH NORTHWEST ONTARIO CAUSED NUMEROUS SHOWERS AND SOME
THUNDERSTORMS. NEGAUNEE IN MARQUETTE COUNTY PICKED UP AS MUCH AS
0.85 INCH OF RAIN UNDER SOME OF THE HEAVIER STORMS, WHICH ALSO
DROPPED HAIL THE SIZE OF NICKLES AND QUARTERS AT SEVERAL SITES OVER
THE CENTRAL U.P.

                          JUNE WEATHER SUMMARY

THE BAND OF SHOWERS THAT MOVED ACROSS UPPER MICHIGAN DURING THE
NIGHT ON 5/31-6/1 WELL AHEAD OF AN APPROACHING COLD FRONT EXITED THE
EASTERN U.P. DURING THE MORNING ON 6/1. WITH THE RETURN OF SOME
SUNSHINE AND THE ARRIVAL OF THE COLD FRONT, MORE SHOWERS AND
THUNDERSTORMS DEVELOPED IN THE AFTERNOON ON 6/1 OVER THE WEST AND
PUSHED INTO THE CENTRAL COUNTIES, WHERE SOME OF THE STRONGER STORMS
DROPPED NICKLE- TO QUARTER-SIZED HAIL INTO THE EARLY EVENING. UP TO
1.06 INCHES OF RAIN FELL NEAR ISHPEMING IN MARQUETTE COUNTY. AS THE
FRONT MOVED TO THE EAST DURING THE NIGHT ON 6/1-6/2, LINGERING
SHOWERS OVER THE EAST ENDED BY MIDNIGHT. WEST WINDS GUSTED AS HIGH
AS 35 MPH BEHIND THE FRONTAL PASSAGE, PUSHING A GOOD DEAL OF CLOUDS
INTO MAINLY WESTERN UPPER MICHIGAN INTO EARLY ON 6/2. AS HIGH
PRESSURE BUILT TOWARD THE WESTERN GREAT LAKES, SKIES ON 6/2 TURNED
MOSTLY SUNNY. THE OVERNIGHT ON 6/2-6/3 WAS A COOL ONE WITH LIGHT
WINDS AND MOSTLY CLEAR SKIES UNDER THE PASSING HIGH. AT WAKEFIELD IN
GOGEBIC COUNTY, THE THERMOMETER READ AS LOW AS 39. MEAN DAILY
TEMPERATURES ON 6/1 AND 6/2 RANGED FROM NEAR NORMAL TO 5 DEGREES
ABOVE AVERAGE.

CLOUDS AHEAD OF A LOW PRESSURE SYSTEM MOVING EAST THROUGH MINNESOTA
AND INTO THE UPPER GREAT LAKES INCREASED ON 6/3. WIDESPREAD RAIN
ARRIVED OVER THE WEST LATE ON 6/3 AND THEN SHIFTED ACROSS UPPER
MICHIGAN. BY THE TIME THIS PRECIPITATION DIMINISHED TO SCATTERED
SHOWERS DURING THE NIGHT ON 6/4-6/5, MANY PLACES HAD PICKED UP 0.50
TO 1.00 INCH OF RAIN. NEWBERRY LED REPORTING STATIONS WITH 1.34
INCHES. ALL THE CLOUDS AND RAIN LIMITED THE RISE IN TEMPERATURE ON
6/4 INTO THE 50S AT SOME OF THE COOLER LOCATIONS OVER THE HIGHER
TERRAIN OF THE NORTH. SOME PATCHY DENSE FOG DEVELOPED DURING THE
NIGHT ON 6/4-6/5 WITHIN THE LINGERING LOW-LEVEL MOISTURE. MORNING
CLOUDS, FOG, AND REMAINING SPRINKLES IN THE MORNING ON 6/5 GAVE WAY
TO SOME CLEARING AS GUSTY NORTHWEST WINDS UP TO 25 TO 30 MPH AHEAD
OF HIGH PRESSURE SLIDING SOUTHEAST THROUGH THE UPPER MIDWEST
ADVECTED DRIER AIR OVER UPPER MICHIGAN. THE MERCURY AVERAGED WITHIN
A COUPLE DEGREES OF NORMAL ON 6/3 THROUGH 6/5.

THE DRY WEATHER ON 6/5 LASTED ONLY A SHORT TIME. A REINFORCING COLD
FRONT ROTATING SOUTHEAST INTO THE UPPER LAKES BEHIND THE DEPARTING
LOW PRESSURE SYSTEM MOVING INTO QUEBEC BROUGHT A RETURN OF MORE
CLOUDS AND SOME SHOWERS OVER THE NORTHWEST U.P. IN THE EARLY MORNING
HOURS ON 6/6. LOTS OF CLOUDS AND NUMEROUS SHOWERS THEN OVERSPREAD
THE REST OF THE AREA ON 6/6 AS THIS FRONT PRESSED TO THE SOUTHEAST.
BEFORE THE SHOWERS DIMINISHED IN THE EARLY MORNING ON 6/7 FOLLOWING
THE EXIT OF THIS FRONT, MANY PLACES HAD PICKED UP 0.50 TO 0.50 INCH
OF RAIN. AS MUCH AS 0.87 INCH FELL AT GREENLAND IN ONTONAGON COUNTY.
NORTHWEST WINDS GUSTED AS HIGH AS 30 TO 35 MPH BEHIND THE FRONTAL
PASSAGE ON 6/6, DRAWING INTO THE AREA THE COOLEST AIRMASS TO
INFLUENCE UPPER MICHIGAN IN JUNE. THIS COOL AIR PERSISTED OVER THE
AREA THROUGH 6/9. HIGH TEMPERATURES IN THE 50S WERE COMMON ON 6/6
THROUGH 6/8 AND ESPECIALLY ON 6/7, WHEN THERE WAS A GRAY OVERCAST
AND A FEW SPRINKLES. SKIES CLEARED DURING THE NIGHT ON 6/7-6/8 WITH
THE CLOSER APPROACH OF CANADIAN HIGH PRESSURE. AS WINDS DIMINISHED
TOO, THE MERCURY DIPPED AS LOW AS 27 NEAR COVINGTON IN BARAGA
COUNTY. AFTER A MOSTLY SUNNY AND COOL DAY ON 6/8 UNDER THE PASSING
HIGH, THE OVERNIGHT ON 6/8-6/9 TURNED OUT TO BE ANOTHER COOL ONE,
ESPECIALLY OVER THE EASTERN U.P. CLOSER TO THE SLOWLY DEPARTING HIGH
PRESSURE. A LOCATION CLOSE TO NEWBERRY REPORTED A LOW OF 27 AROUND
SUNRISE ON 6/9. THE DAY ON 6/9 WAS MOSTLY SUNNY AND PLEASANTLY WARM.
MEAN DAILY TEMPERATURES ABOUT 5 DEGREES BELOW AVERAGE ON 6/6 FELL
OFF TO AROUND 10 DEGREES BELOW NORMAL ON 6/7 AND 6/8. THE
THERMOMETER AVERAGED ABOUT 5 DEGREES BELOW NORMAL ON 6/9.

SOUTH WINDS GUSTING AS HIGH AS 30 MPH ON 6/10 BETWEEN THE DEPARTING
CANADIAN HIGH PRESSURE TO THE EAST AND AN APPROACHING COLD FRONT IN
MINNESOTA BROUGHT A QUICK RETURN OF WARMER AND MORE HUMID CONDITIONS
THAT FUELED THE DEVELOPMENT OF SHOWERS AND SOME STRONG THUNDERSTORMS
DURING THE LATE AFTERNOON AND EVENING ON THAT DAY. THERE WAS SOME
WIND DAMAGE REPORTED IN GOGEBIC COUNTY AND SOME LOCALLY HEAVY RAIN
AS WELL. IRONWOOD PICKED UP 0.95 INCH OF RAIN. PRECIPITATION TOTALS
BETWEEN 0.10 AND 0.75 INCH WERE COMMON ACROSS UPPER MICHIGAN DURING
THIS EVENT. THE SHOWERS AND STORMS THAT LINGERED OVER THE EAST HALF
DURING THE EVENING ON 6/10 THEN ENDED WITH THE ARRIVAL OF DRIER AIR
ALOFT THAT ALLOWED SOME PATCHY FOG TO DEVELOP IN THE EARLY MORNING
ON 6/11. NORTHWEST WINDS GUSTED AS HIGH AS 35 MPH BEHIND THE COLD
FRONTAL PASSAGE ON 6/11 PUSHED DRIER AIR INTO THE AREA AND BROUGHT A
RETURN OF MOSTLY SUNNY WEATHER BY THE AFTERNOON. THE WINDS
DIMINISHED DURING THE EVENING ON 6/11, LEADING TO A MOSTLY CLEAR AND
COOL OVERNIGHT ON 6/11-6/12. MEAN DAILY TEMPERATURES WERE AROUND 5
DEGREES ABOVE NORMAL ON 6/10 AND 5 TO 10 DEGREES ABOVE AVERAGE ON
6/11.

AN AREA OF HIGH PRESSURE BUILDING INTO THE UPPER GREAT LAKES THEN
BROUGHT DRY AND COOL WEATHER TO UPPER MICHIGAN ON 6/12 WITH A MEAN
DAILY TEMPERATURE AROUND 5 DEGREES BELOW NORMAL. BUT AS A LOW
PRESSURE SYSTEM TRACKED SOUTHEAST THROUGH MINNESOTA AND THE UPPER
MIDWEST LATER ON 6/12 INTO 6/13, MORE CLOUDS RETURNED. THERE WERE
ALSO SOME SHOWERS, MAINLY OVER THE WEST NEAR THE WISCONSIN BORDER
DURING THE EARLY MORNING HOURS ON 6/13. AS MUCH AS 0.25 TO 0.50 INCH
OF RAIN FELL IN THIS AREA, WITH UP TO 0.57 INCH NEAR MARENISCO IN
GOGEBIC COUNTY. LOTS OF CLOUDS BUT ONLY A FEW SPRINKLES THEN
PERSISTED THROUGH 6/13 AND INTO 6/14. THE THERMOMETER AVERAGED ABOUT
5 DEGREES BELOW NORMAL ON 6/13.

THE NEXT WIDESPREAD RAIN ARRIVED LATE ON 6/14 AHEAD OF ANOTHER
STRONG UPPER DISTURBANCE MOVING THROUGH MINNESOTA. BANDS OF SHOWERS
AND THUNDERSTORMS AHEAD OF THIS FEATURE AND AN ACCOMPANYING SURFACE
LOW PRESSURE SYSTEM AND WARM FRONT IMPACTED THE U.P. INTO EARLY
6/16. SOME LOCALLY HEAVY RAIN FELL, ESPECIALLY NEAR THE WISCONSIN
BORDER AND THE APPROACHING WARM FRONT. IRONWOOD ONCE AGAIN LED
REPORTING STATIONS WITH 2.46 INCHES OF PRECIPITATION. MENOMINEE WAS
CLOSE BEHIND WITH 2.28 INCHES. MOST PLACES PICKED UP 0.25 TO 0.75
INCH OF RAIN. LOCALLY DENSE FOG DEVELOPED OVER CENTRAL UPPER
MICHIGAN DURING THE EVENING ON 6/15. A MEAN DAILY TEMPERATURE A
COUPLE DEGREES ABOVE NORMAL ON 6/14 FELL OFF TO AS MUCH AS 5 TO 10
DEGREES BELOW AVERAGE ON 6/15 WITH THE RETURN OF THICKER CLOUDS AND
MORE PRECIPITATION. AT SOME OF THE COOLER LOCATIONS NEAR LAKE
SUPERIOR ON 6/15, DAYTIME TEMPERATURES HELD IN THE 50S.

A CANADIAN HIGH PRESSURE SYSTEM EXPANDED INTO THE UPPER GREAT LAKES
ON 6/16 UNDER A BUILDING UPPER RIDGE OVER CENTRAL NORTH AMERICA. ANY
LINGERING CLOUDS ON 6/16 GAVE WAY TO A MOSTLY SUNNY AFTERNOON, WITH
MOSTLY CLEAR SKIES PREVAILING THROUGH 6/17. A NEAR NORMAL MEAN DAILY
TEMPERATURE ON 6/16 ROSE TO ABOUT 5 DEGREES ABOVE AVERAGE ON 6/17 AS
A SOUTHWEST FLOW AROUND HIGH PRESSURE SHIFTING TO THE EAST DREW
WARMER AIR OVER UPPER MICHIGAN. THE THERMOMETER TOPPED OUT WELL INTO
THE 80S AT MANY PLACES INLAND FROM THE LAKES ON 6/17, AND READINGS
EVEN TOUCHED 90 AT SENEY IN SCHOOLCRAFT COUNTY. THE PERSISTENT
SOUTHWEST FLOW AROUND THE HIGH PRESSURE AREA SHIFTING SLOWLY INTO
THE MID ATLANTIC STATES DELIVERED VERY WARM WEATHER THROUGH THE
FARTHER`S DAY WEEKEND EVEN THOUGH SKIES WERE PARTLY TO MOSTLY CLOUDY
ON 6/18 AND 6/19. BUT EXCEPT FOR A FEW SHOWERS AND THUNDERSTORMS
OVER THE KEWEENAW CLOSE TO A WARM FRONT ACROSS NORTHERN LAKE
SUPERIOR DURING THE NIGHT ON 6/18-6/19, THE WEATHER THROUGH 6/19 WAS
DRY. MAXIMUM TEMPERATURES REACHED 92 AT PELKIE IN BARAGA COUNTY AND
90 AT THE HOIST BASIN IN NORTHWEST MARQUETTE COUNTY ON 6/19. THE
THERMOMETER AVERAGED 15 DEGREES ABOVE NORMAL ON BOTH 6/18 AND 6/19.
BEFORE A COLD FRONT PASSED EARLY ON 6/20 AND ENDED THIS HEAT WAVE,
LOW TEMPERATURES THAT MORNING DID NOT FALL BELOW 70 AT SOME PLACES.
MENOMINEE REPORTED AN UNCOMFORTABLE MINIMUM TEMPERATURE OF 74 EARLY
ON 6/20. THERE WERE SOME SCATTERED SHOWERS AND THUNDERSTORMS OVER
MAINLY NORTHWEST UPPER MICHIGAN AHEAD OF THE FRONT DURING THE NIGHT
ON 6/19-6/20, BUT NO PLACE REPORTED MORE THAN 0.10 INCH OF RAIN.
BEHIND THE FRONTAL PASSAGE ON 6/20, NORTHWEST WINDS GUSTED AS HIGH
AS 51 MPH AT THE HOUGHTON COUNTY AIRPORT. THESE STRONG WINDS CAUSED
SOME MINOR DAMAGE. DESPITE A GOOD DEAL OF SUNSHINE, COOLER AIR
RETURNED, DROPPING THE 6/20 MEAN DAILY TEMPERATURE TO 5 TO 10
DEGREES ABOVE NORMAL.

A TRAILING RIDGE OF HIGH PRESSURE OVER THE NORTHERN PLAINS ON 6/21
MOVED SLOWLY TO THE EAST, REACHING THE LOWER GREAT LAKES ON 6/24 AND
BRINGING DRY AND COOLER WEATHER TO UPPER MICHIGAN DURING THIS
STRETCH. THE ONLY EXCEPTION WAS LATER ON 6/22 INTO THE MORNING ON
6/23, WHEN A WEAK DISTURBANCE PASSING THROUGH WISCONSIN BROUGHT MORE
CLOUDS AND A FEW SHOWERS TO MAINLY THE SOUTHWEST HALF OF UPPER
MICHIGAN. WHERE SKIES WERE MOSTLY CLEAR, A FEW OF THE COOLER INLAND
SPOTS SAW LOW TEMPERATURES IN THE 30S EARLY ON 6/22, INCLUDING A
CHILLY 32 AT A PLACE NEAR NEWBERRY. THERE WERE SOME 30S AGAIN NEAR
SUNRISE ON 6/24. THE LOCATION CLOSE TO NEWBERRY WAS THE COOL SPOT
AGAIN WITH A MINIMUM OF 36. DAILY AVERAGE TEMPERATURES WERE AROUND 5
DEGREES BELOW NORMAL ON 6/21 AND 6/23, BUT UP TO 10 DEGREES BELOW
NORMAL ON 6/22. AFTER THE HIGH MOVED TO THE EAST ON 6/24 AND A
SOUTHERLY FLOW DEVELOPED, THE MERCURY REBOUNDED UP TO 5 DEGREES
ABOVE NORMAL.

AFTER A MOSTLY CLEAR AND WARMER NIGHT ON 6/24-6/25, A CLUSTER OF
SHOWERS AND THUNDERSTORMS WITH SOME HEAVY RAIN MOVED ACROSS UPPER
MICHIGAN ON 6/25 TO THE NORTH OF AN APPROACHING WARM FRONT. THE
STRONGER STORMS CAUSED WIND GUSTS UP TO 50 MPH OVER THE KEWEENAW AND
NEAR THE WISCONSIN BORDER ALONG WITH SOME WIND DAMAGE. ANOTHER BAND
OF SHOWERS AND STORMS AHEAD OF A COLD FRONT CROSSED THE AREA DURING
THE NIGHT ON 6/25-6/26, ACCOMPANIED ONCE AGAIN WITH HEAVY RAIN AND
GUSTY WINDS. RAINFALL TOTALS ON 6/25 THROUGH THE MORNING ON 6/26
EXCEEDED AN INCH AT MANY LOCATIONS, WITH AS MUCH AS 2.37 INCHES
FALLING AT ATLANTIC MINE IN HOUGHTON COUNTY AND 2.05 INCHES AT
MENOMINEE. NEWBERRY HAD THE LEAST PRECIPITATION DURING THIS EVENT
WITH 0.40 INCH. AFTER THE FRONT AND THIS LAST BAND OF SHOWERS PASSED
IN THE MORNING ON 6/26, THE WEATHER TURNED MOSTLY SUNNY AND BREEZY
WITH WEST WIND GUSTS UP TO 35 MPH. ABUNDANT CLOUD COVER ON 6/25 HELD
THE MEAN DAILY TEMPERATURE TO AROUND 5 DEGREES ABOVE NORMAL. EVEN
THOUGH THE COLD FRONT PASSED EARLY ON 6/26, THE RETURN OF SUNSHINE
THAT BOOSTED TEMPERATURES WELL INTO THE 80S AT MOST PLACES RESULTED
IN A DAILY AVERAGE TEMPERATURE CLOSE TO 10 DEGREES ABOVE NORMAL ON
THAT DAY.

EVEN STRONGER NORTHWEST WIND GUSTS UP TO 45 TO 50 MPH DEVELOPED OVER
THE KEWEENAW PENINSULA DURING THE NIGHT ON 6/26-6/27 ACCOMPANYING
THE PASSAGE OF A REINFORCING COLD FRONT THAT BROUGHT PLENTY OF
CLOUDS AND SOME LIGHT SHOWERS THROUGH MOST OF 6/27 AND COOL WEATHER
TO END THE MONTH. RAINFALL AMOUNTS WERE GREATEST OVER THE NORTHWEST
BUT NO MORE THAN ABOUT 0.10 INCH. HIGH TEMPERATURES FAILED TO REACH
THE 60-DEGREE MARK OVER THE HIGHER TERRAIN OF THE NORTHWEST UNDER
THE ABUNDANT CLOUD COVER. THE CLOSER APPROACH OF HIGH PRESSURE
CAUSED CLEARING IN THE MORNING ON 6/28 AND BROUGHT MAINLY CLEAR
SKIES INTO THE EVENING ON 6/29. MORNING LOWS ON 6/29 DIPPED INTO THE
30S AT THE INTERIOR COOL SPOTS AND AS LOW AS 34 AT THE LOCATION NEAR
NEWBERRY. MEAN DAILY TEMPERATURES ON 6/27 THROUGH 6/29 RAN 5 TO 10
DEGREES BELOW NORMAL.

CLOUDS BEGAN TO OVERSPREAD THE U.P. IN ADVANCE OF AN APPROACHING
FRONT DURING THE NIGHT ON 6/29-6/30. NUMEROUS SHOWERS AND A FEW
THUNDERSTORMS ROLLED ACROSS UPPER MICHIGAN ON 6/30 AHEAD OF THIS
FRONT. MOST PLACES PICKED UP 0.25 TO 0.75 INCH OF RAIN ON 6/30. AS
MUCH AS 1.03 INCHES FELL AT CHATHAM IN ALGER COUNTY BY THE TIME THE
PRECIPITATION DIMINISHED DURING THE EVENING ON 6/30. THE THERMOMETER
AVERAGED ABOUT 5 DEGREES BELOW NORMAL ON 6/30 AS COOL AIR FOLLOWED
THE FRONT AND FOG ROLLED OFF LAKE SUPERIOR INTO SOME COASTAL
LOCATIONS.
                          AUGUST FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING EQUAL CHANCES OF
AN ABOVE AND BELOW NORMAL MONTHLY MEAN TEMPERATURE BUT A GREATER
THAN CLIMATOLOGICAL CHANCE OF BELOW NORMAL MONTHLY PRECIPITATION
ACROSS ALL OF UPPER MICHIGAN IN AUGUST 2016.

                         AUGUST CLIMATOLOGY

AFTER PEAKING IN JULY...AVERAGE TEMPERATURES IN AUGUST BEGIN TO
SLIDE AS THE SUN CONTINUES ITS LATE YEAR JOURNEY SOUTH. POSSIBLE
SUNSHINE DECLINES FROM 892 MINUTES ON 8/1 TO 804 MINUTES ON 8/31...
AND AVERAGE TEMPERATURES ARE ONE TO TWO DEGREES LOWER THAN IN JULY.

BUT SUMMER ACROSS UPPER MICHIGAN IS NOT OVER YET IN AUGUST. ALTHOUGH
100 DEGREE TEMPERATURES ARE RARE DURING THE EIGHTH MONTH...SUCH HEAT
IS NOT UNPRECEDENTED. IN AUGUST 2001...BARK RIVER IN DELTA COUNTY
SAW THE MERCURY RISE AS HIGH AS 102 ON 8/7 AND 101 ON 8/6 DURING A
TORRID HEAT WAVE BETWEEN 8/5 AND 8/8. 8/5/47 GOES DOWN IN THE RECORD
BOOKS OVER MUCH OF UPPER MICHIGAN AS THE HOTTEST AUGUST DAY SINCE
RECORDS BEGAN. IRON MOUNTAIN (101)...IRONWOOD (101)...AND DOWNTOWN
MARQUETTE (102) ALL RECORDED THEIR ALL TIME HIGHEST AUGUST
TEMPERATURES ON THAT SWELTERING DAY. AUGUST 1947 IS ALSO THE WARMEST
AUGUST ON RECORD AT IRONWOOD (73.4 DEGREE AVERAGE TEMPERATURE)...
IRON MOUNTAIN (72.4)...AND NEWBERRY (69.6).

ALTHOUGH SUMMER HEAT CAN STILL GRIP THE AREA IN AUGUST...COOLER AIR
MASSES MAKE MORE FREQUENT VISITS TO THE NORTHERN GREAT LAKES DURING
THE EIGHTH MONTH. AS THE NIGHTS LENGTHEN IN AUGUST...FROST BECOMES
A  GREATER THREAT OVER ESPECIALLY INTERIOR LOCATIONS AWAY FROM THE
MODERATING INFLUENCE OF THE GREAT LAKES (LAKE WATER TEMPERATURES
TYPICALLY REACH THEIR HIGHEST LEVELS IN MID TO LATE AUGUST). THE
LOW  TEMPERATURE AT IRONWOOD HAS REACHED FREEZING AS EARLY AS
8/4...IN  1907. BETWEEN 8/19 AND 8/21 IN 2000...SOME SHELTERED
INLAND LOCATIONS REPORTED FROST. AUGUST 2004 WAS THE COOLEST EIGHTH
MONTH IN RECENT MEMORY. MONTHLY TEMPERATURES AVERAGED 3 TO 6 DEGREES
BELOW NORMAL...AND AUGUST 2004 GOES DOWN IN THE RECORD BOOKS IN THE
LIST OF TOP 10 COOLEST AT ALMOST ALL REPORTING STATIONS. PATCHY
FROST WAS OBSERVED OVER THE COOLER INLAND LOCATIONS IN AUGUST 2004
BETWEEN 8/19 AND 8/21.

PRECIPITATION IN AUGUST CAN BE QUITE VARIABLE DEPENDING ON THE
FREQUENCY OF THUNDERSTORMS. THE DRIEST EIGHTH MONTH IN RECENT YEARS
OCCURRED IN 2008...WHEN MANY PLACES ENDURED ONE OF THE TOP FIVE
DRIEST AUGUSTS ON RECORD IN THE ABSENCE OF MUCH CONVECTION. ONLY
0.42 INCH AND 0.44 INCH OF RAIN FELL IN THE CITY OF MARQUETTE AND AT
THE MARQUETTE NWS IN THAT DRY MONTH...WHICH GOES DOWN IN THE RECORD
BOOKS AS THE DRIEST AUGUST ON RECORD AT THOSE LOCATIONS. 2007 ALSO
FEATURED A TOP TEN DRIEST EIGHTH MONTH AT MOST LOCATIONS THAT HELPED
DROP LAKE SUPERIOR TO A RECORD LOW LEVEL. ON THE OTHER HAND...SLOW
MOVING THUNDERSTORMS CAN STILL THREATEN THE UPPER PENINSULA WITH
TORRENTIAL RAIN. A TOTAL OF 11.15 INCHES OF RAIN INUNDATED IRONWOOD
DURING AUGUST 1941.

                          OUTLOOK FOR FALL

THE CPC IS FORECASTING A GREATER THAN CLIMATOLOGICAL CHANCE OF AN
ABOVE NORMAL 3-MONTH AVERAGE TEMPERATURE BUT EQUAL CHANGES OF ABOVE
AND BELOW NORMAL 3-MONTH PRECIPITATION OVER ALL OF UPPER MICHIGAN IN
SEPTEMBER THROUGH NOVEMBER 2016.
