...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.

                            JULY 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 ACROSS ALL OF UPPER MICHIGAN IN
JULY 2017.

                          JULY CLIMATOLOGY

ALTHOUGH DAYLIGHT BEGINS TO GROW SHORTER DURING JULY (946 MINUTES OF
POSSIBLE SUNSHINE ON 7/1 DECREASES TO 894 MINUTES ON 7/31) AS THE
SUN STARTS ITS ANNUAL MIGRATION SOUTHWARD...AVERAGE MONTHLY
TEMPERATURES PEAK DURING THE SEVENTH MONTH...ABOUT 5 DEGREES HIGHER
THAN IN JUNE. TEMPERATURES OVER 100 ARE RARE IN UPPER MICHIGAN...BUT
THEY ARE MOST LIKELY IN JULY. THE MOST EXTREME HEATWAVE IN UPPER
MICHIGAN HISTORY OCCURRED DURING THE SECOND WEEK OF JULY 1936.
RESIDENTS OF NEWBERRY ENDURED SIX DAYS IN A ROW FROM 7/8/36 TO
7/13/36 WHERE THE HIGH TEMPERATURE REACHED 100 OR ABOVE...INCLUDING
AN ALL TIME RECORD 103 DEGREE READING ON 7/13/36. IN FACT...THE
SEVEN HOTTEST DAYS IN NEWBERRY HISTORY OCCURRED DURING THE WEEK OF
7/8/36 TO 7/14/36. IRONWOOD AND IRON MOUNTAIN ALSO RECORDED THEIR
ALL TIME HIGHEST TEMPERATURE ON 7/13/36 WITH MAXIMUM TEMPERATURES OF
104 AND 103 RESPECTIVELY. EVEN THOUGH THE 104 READING IN DOWNTOWN
MARQUETTE ON 7/13/36 IS NOT THE HIGHEST TEMPERATURE EVER OBSERVED
THERE...WHICH IS 108 ON 7/15/1901...THAT FACT PROBABLY WAS OF LITTLE
COMFORT TO LOCAL RESIDENTS...WHO ALSO SUFFERED THROUGH SWELTERING
LOW TEMPERATURES OF 80 ON 7/8/36 AND 7/9/36.

IN RECENT MEMORY...JULY IN 2006 AND 2011 WERE QUITE WARM OVER UPPER
MICHIGAN WITH MONTHLY MEAN TEMPERATURES AVERAGING 2 TO 5 DEGREES
ABOVE THE 30-YEAR NORMAL. THOUSAND ISLAND LAKE IN GOGEBIC COUNTY
REPORTED A MAXIMUM TEMPERATURE OF 100 OR BETTER ON FOUR DAYS IN JULY
2006...WHICH GOES DOWN IN THE RECORD BOOKS AS ONE OF THE TOP 10
WARMEST SEVENTH MONTHS AT ALL REPORTING SITES. JULY 2011 WAS ALSO
ONE OF THE TOP 10 WARMEST AT MANY LOCATIONS.

AT THE OTHER EXTREME...COOL AIRMASSES FROM CANADA CAN BRING FROST TO
MAINLY OUTLYING AREAS OF UPPER MICHIGAN DURING JULY. IRONWOOD
RECORDED A 31 DEGREE READING ON 7/2/1907...AND NEWBERRY OBSERVED 32
ON 7/21/92. ON 7/19 AND 7/20/2000...FROST DEVELOPED AT SOME INTERIOR
LOCATIONS AS CANADIAN HIGH PRESSURE PARKED ITSELF OVERHEAD AND
DROPPED THE MERCURY AS LOW AS 28. JULY 1992 GOES DOWN IN THE RECORD
BOOKS AT MOST UPPER MICHIGAN STATIONS AS THE COOLEST EVER. MEAN JULY
1992 TEMPERATURES THROUGHOUT THE AREA AVERAGED SIX TO NINE DEGREES
BELOW THE NORMAL OF 65 TO 68. JULY 2009 ENDED UP AS THE SECOND
COOLEST SEVENTH MONTH ON RECORD AT MOST PLACES...TRAILING ONLY JULY
1992 WITH A MEAN MONTHLY TEMPERATURE 4 TO 6 DEGREES BELOW AVERAGE.
JULY 2004 WAS ALSO QUITE CHILLY...WITH MOST LOCATIONS OBSERVING
MONTHLY AVERAGE TEMPERATURES 2 TO 5 DEGREES BELOW NORMAL.

ALTHOUGH THE AVERAGE JULY TENDS TO BE DRIER THAN JUNE BECAUSE THE
JET STREAM AND MOST WEATHER DISTURBANCES ARE FARTHER NORTH...
FREQUENT JULY THUNDERSTORMS CAN DROP HEAVY RAINS. DURING THE
OVERNIGHT OF 7/14-7/15 IN 1999...THUNDERSTORMS DELUGED SOUTHERN IRON
COUNTY WITH AS MUCH AS 8 INCHES OF RAIN AND CAUSED SOME FLASH
FLOODING. IN JULY 1909...AS MUCH AS 15.45 INCHES OF RAIN INUNDATED
IRONWOOD. MOST OF THIS RAIN FELL ON 7/19 INTO 7/22...WHEN THAT SITE
REPORTED AN INCREDIBLE 13.21 INCHES DURING THAT FOUR DAY STRETCH.

                  OUTLOOK FOR LATE SUMMER INTO FALL

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
ACROSS ALL OF UPPER MICHIGAN IN AUGUST THROUGH OCTOBER 2017.
