...WATER LEVELS REMAIN WELL ABOVE NORMAL IN JUNE...
...LAKE SUPERIOR WATER LEVEL NEAR RECORD HIGHEST...

RUNOFF FROM MODERATE TO HEAVY PRECIPITATION THAT OCCURRED FROM APRIL
THROUGH JUNE CONTRIBUTED TO RISING WATERS LEVELS IN JUNE. AT THE END
OF JUNE, WATER LEVELS ON LAKE SUPERIOR WERE 11 TO 12 INCHES ABOVE
NORMAL AND 5 TO 6 INCHES HIGHER THAN OBSERVED IN JUNE 2016. IN FACT,
THE LEVEL ON LAKE SUPERIOR ON 6/30 WAS LESS THAN AN INCH BELOW THE
RECORD HIGHEST LEVEL OBSERVED IN 1986. THE LEVEL ON LAKES MICHIGAN
AND HURON ENDED UP 17 TO 18 INCHES ABOVE NORMAL AND ALSO 5 TO 6
INCHES HIGHER THAN THE LEVEL OBSERVED IN JUNE 2016.

                       JUNE CLIMATE HIGHLIGHTS

HIGHEST REPORTED TEMPERATURE...94 AT GAY IN KEWEENAW COUNTY ON 6/10

LOWEST REPORTED TEMPERATURE...28 NEAR NEWBERRY ON 6/2

HIGHEST AVERAGE TEMPERATURE...64.5 DEGREES AT IRON MOUNTAIN

LOWEST AVERAGE TEMPERATURE...57.0 DEGREES AT COPPER HARBOR

HIGHEST MONTHLY PRECIPITATION...10.23 INCHES AT MENOMINEE

LOWEST MONTHLY PRECIPITATION...2.57 INCHES AT COPPER HARBOR

AN ACTIVE, CHANGEABLE FLOW ALOFT PREVAILED OVER THE UPPER GREAT
LAKES DURING JUNE, RESULTING IN FREQUENT SHOWER AND THUNDERSTORM
EPISODES AND HEAVY MONTHLY PRECIPITATION ACROSS UPPER MICHIGAN. THE
HEAVIEST RAINS FELL OVER THE SOUTH CENTRAL, WHERE SOME PLACES SAW AS
MUCH AS 10 INCHES OF PRECIPITATION, INCLUDING THE MONTHLY MAXIMUM OF
10.23 INCHES AT MENOMINEE. SOME LOCATIONS ACROSS THE SOUTH CENTRAL
ENDED UP WITH 250 PERCENT OF NORMAL JUNE RAINFALL. ALTHOUGH MONTHLY
PRECIPITATION WAS LESS OVER THE NORTHWEST U.P., MOST PLACES IN THIS
AREA STILL MEASURED AT LEAST 3.50 TO 5.00 INCHES OF RAIN, GENERALLY
ABOVE NORMAL TOTALS. AT SEVERAL SPOTS, JUNE 2017 IS NOW ONE OF THE
TOP TEN WETTEST SIXTH MONTH ON RECORD.

THE CHANGEABLE NATURE OF THE FLOW THAT FEATURED PERIODS OF COOL AND
WARM WEATHER CAUSED JUNE MEAN TEMPERATURE TO END UP WITHIN A DEGREE
OF THE MONTHLY NORMAL AT MOST PLACES. SINCE MAY WAS QUITE COOL, MEAN
JUNE TEMPERATURES RANGING FROM 57 TO NEAR 65 DEGREES WERE 11 TO 14
DEGREES HIGHER THAN THE MAY READINGS.

                           AUGUST 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
OVER ALL OF UPPER MICHIGAN IN AUGUST 2017.

                          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 INTERIOR
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 IS IN THE LIST OF TOP 10 COOLEST
AUGUSTS AT ALMOST ALL REPORTING STATIONS.  PATCHY FROST WAS ALSO
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 CONVENTION.  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 CHANCES OF ABOVE
AND BELOW NORMAL 3-MONTH PRECIPITATION ACROSS ALL OF UPPER MICHIGAN
IN SEPTEMBER THROUGH NOVEMBER 2017.
