...GREAT LAKES WATER LEVELS WELL ABOVE NORMAL AGAIN IN MAY...

AS IS NORMAL...GREAT LAKES WATER LEVELS ROSE IN MAY 2015. EXTENSIVE
ICE COVER ON LAKE SUPERIOR THIS PAST WINTER THAT HAS HELD DOWN WATER
TEMPERATURES AND LIMITED EVAPORATION AS WELL AS RUNOFF FROM SOME
PERIODS OF HEAVY RAIN IN MAY AIDED THESE WATER LEVEL RISES. AT THE
END OF MAY...WATER LEVELS ON LAKE SUPERIOR WERE 9 TO 10 INCHES ABOVE
NORMAL AND 4 TO 5 INCHES HIGHER THAN THE MAY AVERAGE IN 2014. THE
LEVEL ON LAKES MICHIGAN AND HURON WAS 6 TO 7 INCHES ABOVE AVERAGE ON
5/31 AND ALMOST 15 INCHES HIGHER THAN DURING MAY 2014.

SOME ICE COVER LINGERED OVER FAR EASTERN LAKE SUPERIOR NEAR THE
ONTARIO SHORELINE NORTH OF WHITEFISH POINT INTO MID MAY BUT MELTED
BY AROUND 5/20.

                            JUNE FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING A GREATER THAN
CLIMATOLOGICAL CHANCE OF AN ABOVE NORMAL MONTHLY MEAN TEMPERATURE
AND BELOW NORMAL MONTHLY PRECIPITATION OVER ALL OF UPPER MICHIGAN IN
JUNE 2015.

                           JUNE CLIMATOLOGY

AVERAGE TEMPERATURES CONTINUE TO RISE DURING JUNE AS DAILY POSSIBLE
SUNSHINE PEAKS AT 950 MINUTES AROUND THE SUMMER SOLSTICE...WHICH
OCCURS THIS YEAR AT 12:38 PM EDT ON 6/21. AT THE MARQUETTE NWS...THE
AVERAGE TEMPERATURE OF 56 ON 6/1 INCREASES TO 64 BY 6/30. THE JUNE
AVERAGE TEMPERATURE AT MOST PLACES OVER UPPER MICHIGAN IS ABOUT NINE
DEGREES HIGHER THAN IN MAY. AN INCREASE IN CONVECTIVE ACTIVITY FROM
MAY TO JUNE ALSO PUSHES AVERAGE MONTHLY PRECIPITATION UP AT MOST
LOCATIONS. SLOW MOVING THUNDERSTORMS CAN DROP TORRENTIAL RAIN...AND
12.26 INCHES OF RAIN DELUGED THE MARQUETTE NWS IN JUNE 1968. THE
HIGHEST RECORD DAILY RAINFALL AMOUNT AT ALL STATIONS IN JUNE EXCEEDS
TWO INCHES.

EVEN THOUGH AVERAGE TEMPERATURES THROUGH THE MONTH SHOW A STEADY
WARMING TREND...FROST REMAINS A THREAT EVEN LATE IN JUNE. THE LATEST
OCCURRENCE OF FREEZING TEMPERATURES AT THE MARQUETTE NWS IS 6/22...
AND AS LATE AS 6/26 AT NEWBERRY. SHELTERED COLD SPOTS IN THE
INTERIOR CAN HAVE FROST THROUGH 6/30. ALTHOUGH ACCUMULATING SNOW IS
RARE...IT CAN OCCUR EARLY IN THE MONTH. ON 6/2/98...HIGHER TERRAIN
AREAS IN NORTH CENTRAL UPPER MICHIGAN RECORDED A SLUSHY INCH OF SNOW.

THE COOLEST JUNE IN RECENT MEMORY WAS IN 2004...WHEN TEMPERATURES
AVERAGED 2 TO 4 DEGREES BELOW NORMAL. BUT JUNE 1982 SAW EVEN LOWER
TEMPERATURES...ABOUT SIX OR SEVEN DEGREES BELOW NORMAL. IN FACT...
JUNE 1982 IS THE COOLEST SIXTH MONTH ON RECORD AT MUNISING (MONTHLY
AVERAGE TEMPERATURE 52.9)...IRONWOOD (54.4)...MARQUETTE CITY
(54.4)...AND ONTONAGON (56.2). JUNE 1982 LANDED IN THE LIST OF TOP
TEN COOLEST AT MOST LOCATIONS.

ALTHOUGH EARLY SPRING CHILL CAN OCCUR IN JUNE...BLISTERING SUMMER
HOT SPELLS ARE ALSO POSSIBLE. RECORD HIGH TEMPERATURES AT ALL
REPORTING STATIONS ARE BETWEEN 94 AND 100. AT ALMOST EVERY
LOCATION...JUNE 2005 IS AMONG THE TOP TEN WARMEST ON RECORD. A
SWELTERING HEAT WAVE WITH DAYTIME HIGHS IN THE 90S AWAY FROM THE
COOLING INFLUENCE OF THE GREAT LAKES DURING PART OF THE FOURTH WEEK
OF THAT MONTH PUSHED AVERAGE MONTHLY TEMPERATURES 3 TO 6 DEGREES
ABOVE NORMAL. AT ONTONAGON (67.9) AND MANISTIQUE (64.0)...JUNE 2005
IS THE WARMEST ON RECORD. JUNE 1995 WAS ALSO VERY WARM...WITH MEAN
TEMPERATURES AVERAGING AS MUCH AS 6 TO 7 DEGREES ABOVE NORMAL. IN
FACT...THAT JUNE IS THE WARMEST ON RECORD AT THE MARQUETTE NWS
(66.3)...THE HOUGHTON COUNTY AIRPORT (66.1)...AND MUNISING (65.1).
ONLY AT IRONWOOD DID JUNE 1995 NOT END UP IN THE TOP TEN WARMEST. A
TORRID HEATWAVE AROUND MID MONTH PUSHED THE MERCURY UP TO THE
CENTURY MARK AT IRON MOUNTAIN ON 6/19/95. THE 78.6-DEGREE AVERAGE
TEMPERATURE AT IRON MOUNTAIN BETWEEN 6/18 AND 6/25 IN 1995 PUTS THAT
EIGHT-DAY STRETCH IN THE RECORD BOOK AS THE WARMEST WEEK IN JUNE
EVER OBSERVED THERE. THE HIGH TEMPERATURE EXCEEDED 90 ON SEVEN OF
THOSE EIGHT DAYS.

               OUTLOOK FOR SUMMER INTO EARLY 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 JULY THROUGH SEPTEMBER 2015.

LOCAL THREE-MONTH AVERAGE TEMPERATURE OUTLOOKS FOR A NUMBER OF SITES
IN UPPER MICHIGAN.

THE CLIMATE PREDICTION CENTER AND MORE LONG RANGE PREDICTIONS.

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.
NOTE ALL TEMPERATURES ARE IN FAHRENHEIT AND PRECIPITATION IS IN
INCHES. ALL CLIMATE DATA LISTED IN THIS PRODUCT ARE UNOFFICIAL. FOR
