...GREAT LAKES WATER LEVELS CONTINUE TO REBOUND IN MAY...

THANKS TO SOME HEAVY LATE WINTER AND SPRING PRECIPITATION AND SNOW
MELT IN THE LAKE SUPERIOR DRAINAGE BASIN...THE WATER LEVEL ON
SUPERIOR ROSE 8 TO 9 INCHES DURING MAY 2013. BUT SINCE INCREASED
EVAPORATION DUE TO RELATIVELY WARM LAKE WATERS AND A LACK OF
SIGNIFICANT WINTER ICE HAS RESULTED IN WELL BELOW NORMAL GREAT LAKES
WATER LEVELS FOR THE PAST SEVERAL YEARS...THE LAKE SUPERIOR WATER
LEVEL ON 5/30 WAS STILL 6 INCHES BELOW THE LONG TERM AVERAGE. AFTER
A SIMILARLY DRAMATIC WATER LEVEL RISE IN APRIL DUE TO HEAVY
PRECIPITATION AS WELL AS EARLIER SNOW MELT AND RUNOFF FARTHER
SOUTH...LAKES MICHIGAN/HURON ROSE 4 TO 5 INCHES IN MAY. SINCE THE
WATER LEVEL DEFICIT ON THESE LAKES WAS UP TO 30 INCHES EARLIER
THIS YEAR...THE LAKE LEVELS ON MICHIGAN/HURON REMAINED 18 TO 19
INCHES BELOW NORMAL ON 5/30.

---------------------------------------------------------------------
                        MAY CLIMATE HIGHLIGHTS

HIGHEST REPORTED TEMPERATURE...88 AT A SPOT 5 MILES WEST OF BARAGA
                                AND AT PELKIE IN BARAGA COUNTY
                                ON 5/30

LOWEST REPORTED TEMPERATURE...17 AT STAMBAUGH IN IRON COUNTY AND
                               KENTON IN HOUGHTON COUNTY ON 5/13

HIGHEST AVERAGE TEMPERATURE...53.8 DEGREES AT NORWAY IN DICKINSON
                               COUNTY AND ESCANABA

LOWEST AVERAGE TEMPERATURE...44.6 DEGREES AT JACOBSVILLE IN HOUGHTON
                              COUNTY

HIGHEST MONTHLY PRECIPITATION...7.14 INCHES AT IRONWOOD

LOWEST MONTHLY PRECIPITATION...1.75 INCHES AT GLADSTONE IN DELTA COUNTY
                                AND DAGGETT IN MENOMINEE COUNTY

HIGHEST MONTHLY SNOWFALL...15.1 INCHES AT IRONWOOD

GREATEST SNOW DEPTH...17 INCHES AT HERMAN IN BARAGA COUNTY
                       ON 5/1 AND 5/3

FOR THE FOURTH MONTH IN A ROW...AN UPPER TROUGH IN EASTERN AND
CENTRAL NORTH AMERICA DOMINATED THE WEATHER IN THE GREAT LAKES IN
MAY 2013...RESULTING IN GENERALLY COOL AND WET WEATHER OVER AT LEAST
THE WEST HALF OF UPPER MICHIGAN. BUT SINCE THIS UPPER PATTERN
RELAXED OCCASIONALLY AND ALLOWED FOR A RETURN OF WARMER WEATHER AT
TIMES ESPECIALLY DURING THE SECOND HALF OF THE MONTH...MAY WAS NOT
AS CHILLY RELATIVE TO NORMAL AS APRIL. MEAN MAY MONTHLY TEMPERATURES
RANGING FROM 45 TO 53 DEGREES RAN FROM NEAR NORMAL OVER THE EAST TO
AS MUCH AS 2 TO 4 DEGREES BELOW AVERAGE OVER THE WEST HALF. MAY
ENDED UP BETWEEN 15 AND AS MUCH AS 21 DEGREES WARMER THAN APRIL JUST
BECAUSE THE FOURTH MONTH IN 2013 WAS SO CHILLY.

AS HAS BEEN THE CASE IN RECENT MONTHS...THE HEAVIEST PRECIPITATION
FELL OVER WESTERN UPPER MICHIGAN IN MAY. FOR THE SECOND MONTH IN A
ROW...IRONWOOD REPORTED THE HIGHEST AMOUNT. THE 7.14 INCHES THAT
FELL THERE WAS JUST SHY OF THE RECORD 7.18 INCHES REPORTED IN MAY
1942 AND AN IMPRESSIVE 230 PERCENT OF THE MONTHLY NORMAL. MOST
PLACES OVER THE NORTHWEST HALF OF UPPER MICHIGAN LOGGED 3 TO 6
INCHES OF PRECIPITATION IN MAY. OVER THE SOUTHEAST HALF...MONTHLY
TOTALS RAN FROM AS LITTLE AS 1.75 INCHES AT A FEW PLACES OVER THE
FAR SOUTH CENTRAL BETWEEN MENOMINEE AND ESCANABA TO AS MUCH 3
INCHES...OR ABOUT 60 PERCENT OF THE MEAN TO NEAR NORMAL.

MOST LOCATIONS ACROSS ALL BUT THE SOUTHEAST REPORTED AT LEAST ONE OR
TWO ACCUMULATING SNOWS IN MAY WITH THE UPPER TROUGH DOMINATING.
IRONWOOD ALSO SAW THE MOST MAY SNOWFALL WITH 15.1 INCHES OF THE
WHITE STUFF. THIS SNOW ACCUMULATED DURING AN EARLY MONTH STORM THAT
IMPACTED THE AREA FROM LATE ON 5/1 INTO 5/3. IN ADDITION TO THE
WET...HEAVY SNOW...SOME FREEZING RAIN AND SLEET ALSO FELL DURING
THIS LATE WINTER STORM. TOTAL LIQUID EQUIVALENT PRECIPITATION AT
IRONWOOD REACHED 2.92 INCHES ON 5/1 INTO 5/3. ALTHOUGH SNOW TOTALS
WERE NOT EXCESSIVE AT MOST PLACES AWAY FROM THE FAR WEST AND UNDER 6
INCHES EXCEPT OVER THE HIGHER TERRAIN...THE SNOW TOTALS WERE AMONG
THE TOP TEN HIGHEST FOR MAY JUST BECAUSE ACCUMULATING SNOWS THIS
LATE IN THE SEASON ARE RELATIVELY RARE.

THE FIRST TWO WEEKS OF MAY WERE PARTICULARLY CHILLY EXCEPT FOR A
BRIEF WARMUP ON 5/7 AND 5/8...WITH MEAN DAILY TEMPERATURES
RUNNING BELOW NORMAL ON THE GREAT MAJORITY OF THE DAYS UNTIL 5/14.
THE MORNING ON 5/13 WAS THE COLDEST OF THE MONTH. THE THERMOMETER
TUMBLED INTO THE TEENS AT SOME OF THE INTERIOR LOCATIONS AND AS LOW
AS THE MONTHLY LOW OF 17 AT STAMBAUGH IN IRON COUNTY AND KENTON IN
FAR SOUTHERN HOUGHTON COUNTY.

TEMPERATURES IN THE 80S BECAME FAIRLY COMMON DURING THE SECOND HALF
OF MAY ONCE THE PATTERN BECAME A BIT MORE VARIABLE WITH A LESS
PERSISTENT UPPER TROUGH. AT LEAST ONE SPOT REPORTED A MAXIMUM
TEMPERATURE OF AT LEAST 80 ON 5/8...5/14...5/15...5/19...5/20...AND
EACH OF THE DAYS FROM 5/29 THROUGH 5/31. THE WARMEST DAY WAS ON
5/30...WHEN SUNSHINE AND A BALMY SOUTHWEST WIND LIFTED THE MERCURY
INTO THE 80S ALMOST EVERYWHERE EXCEPT THE EAST DOWNWIND OF LAKE
MICHIGAN AND RIGHT ALONG THE LAKE SUPERIOR SHORE. A SPOT 5 MILES
WEST OF BARAGA AND PELKIE IN BARAGA COUNTY REPORTED THE MONTHLY HIGH
OF 88 ON 5/30. THIS LATE MONTH WARM SPELL SET THE STAGE FOR THE
SEASON`S FIRST SEVERE THUNDERSTORMS DURING THE EVENINGS ON 5/30 AND
5/31...WHEN DAMAGING WINDS AND/OR LARGE HAIL IMPACTED SOME PLACES IN
IRON...DICKINSON...MARQUETTE...BARAGA AND HOUGHTON COUNTIES.

DESPITE THE EARLY MONTH CHILL...MINOR RIVER FLOODING CAUSED BY THE
MELTING OF THE EXCESSIVE LATE SEASON SNOW PACK IN THE WARM SPELL AT
THE END OF APRIL CONTINUED THE FIRST TWO WEEKS OF MAY...MAINLY OVER
THE WEST HALF OF UPPER MICHIGAN. FORTUNATELY...NO HEAVY RAIN
OCCURRED AT THIS TIME TO EXACERBATE THE RUNOFF AND FLOODING. A ROUND
OF HEAVY RAIN DID FALL IN THE WEEK BETWEEN 5/17 AND 5/23...WITH 2
INCHES OR MORE OF PRECIPITATION FALLING AT MANY PLACES OVER THE
WEST. BERGLAND DAM IN ONTONAGON COUNTY AND IRONWOOD PICKED UP 3.90
AND 3.60 INCHES OF RAIN RESPECTIVELY DURING THIS TIME. THESE HEAVY
RAINS LIFTED RIVER LEVELS BACK TOWARD BANKFULL OVER THE WETTER
WESTERN UPPER PENINSULA. BUT SINCE THE BULK OF THE SNOW MELT RUNOFF
HAD ALREADY PASSED THROUGH THE RIVERS BY THIS TIME...ANY FLOODING
WAS MINOR.
---------------------------------------------------------------------
 ...CHILLY WITH ABOVE NORMAL PRECIPITATION AND SNOW IN MARCH-MAY...

THE PERSISTENCE OF AN UPPER TROUGH OVER CENTRAL AND EASTERN NORTH
AMERICA HAS RESULTED IN A CHILLY...ACTIVE WEATHER PATTERN OVER THE
UPPER GREAT LAKES FROM THE MIDDLE OF JANUARY THROUGH MAY. MANY
LOCATIONS ACROSS MAINLY WESTERN UPPER MICHIGAN SAW A TOP 10 WETTEST
AND SNOWIEST MARCH THROUGH MAY PERIOD...WITH PRECIPITATION AND
SNOWFALL AS MUCH AS 200 PERCENT OR MORE OF THE 30-YEAR NORMAL. IN
FACT...RECORD MARCH THROUGH MAY SNOW FELL AT IRONWOOD AND HOUGHTON
IN 2013. THE 91.0 INCHES THAT ACCUMULATED AT IRONWOOD ON 3/1 THROUGH
5/31 IS OVER 50 INCHES ABOVE THE 30-YEAR AVERAGE AND ALMOST A FOOT
MORE THAN THE PREVIOUS RECORD TOTAL THAT FELL THERE DURING THIS SAME
PERIOD IN 2002. A FEW PLACES ALSO EXPERIENCED A TOP 10 COOLEST MARCH
THROUGH MAY...WITH THE MEAN 3-MONTHLY TEMPERATURES RUNNING 2 TO AS
MUCH AS 5 TO 6 DEGREES BELOW NORMAL.

                           JUNE FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING AN EQUAL CHANCE
OF AN ABOVE AND BELOW NORMAL MONTHLY MEAN TEMPERATURE AND ABOVE AND
BELOW NORMAL MONTHLY PRECIPITATION OVER ALL OF UPPER MICHIGAN IN JUNE
2013.

                          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 1:04 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 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
OVER ALL OF UPPER MICHIGAN IN JULY THROUGH SEPTEMBER 2013.
