                           JUNE FORECAST

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

                          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 6:34 AM EDT ON 6/20. 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 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
JULY THROUGH SEPTEMBER 2016.
