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

WATER LEVELS ON THE WESTERN GREAT LAKES REMAINED NEARLY STEADY IN
JULY AS LIMITED EVAPORATION CAUSED BY RELATIVELY CHILLY WATER
TEMPERATURES OFFSET GENERALLY BELOW NORMAL RAINFALL AND RUNOFF IN
THE LAKES DRAINAGE BASINS. AT THE END OF JULY...WATER LEVELS ON LAKE
SUPERIOR WERE 7 TO 8 INCHES ABOVE NORMAL AND ABOUT 1 INCH HIGHER
THAN THE JULY AVERAGE IN 2014. THE LEVEL ON LAKES MICHIGAN AND HURON
WAS 6 TO 7 INCHES ABOVE AVERAGE ON 7/30 AND 10 TO 11 INCHES HIGHER
THAN DURING JULY 2014.

                           AUGUST 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
AUGUST 2015.

                          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 CLIMATE PREDICTION CENTER (CPC) IS FORECASTING AN EQUAL CHANCE
OF AN ABOVE AND BELOW NORMAL 3-MONTH AVERAGE TEMPERATURE AND ABOVE
AND BELOW AVERAGE 3-MONTH PRECIPITATION OVER ALL OF UPPER MICHIGAN
IN SEPTEMBER THROUGH NOVEMBER 2015.

NOTE THAT STATISTICS FOR THE NATIONAL WEATHER SERVICE OFFICE IN
NEGAUNEE TOWNSHIP ARE BASED ON RECORDS WHICH BEGAN IN OCTOBER 1961.
THIRTY YEAR NORMALS USED ARE FOR THE PERIOD OF 1981 THROUGH 2010.

INCHES. ALL CLIMATE DATA LISTED IN THIS PRODUCT ARE UNOFFICIAL. FOR
