MAY CLIMATE HIGHLIGHTS  
 
HIGHEST AVERAGE TEMPERATURE...51.6 DEGREES AT IRON MOUNTAIN  
 
LOWEST AVERAGE TEMPERATURE...44.5 DEGREES AT JACOBSVILLE IN HOUGHTON  
COUNTY  
 
HIGHEST MONTHLY PRECIPITATION...6.71 INCHES AT WATERSMEET IN GOGEBIC  
COUNTY  
 
LOWEST MONTHLY PRECIPITATION...2.63 INCHES AT MANISTIQUE  
 
HIGHEST MONTHLY SNOWFALL...2.1 INCHES AT BERGLAND DAM IN ONTONAGON  
COUNTY  
 
ALTHOUGH THERE WAS GENERALLY DRY WEATHER FROM 5/3 TO 5/15, AN ACTIVE  
WEATHER PATTERN PREVAILED MUCH OF THE REST OF MAY 2017 ACROSS THE  
UPPER GREAT LAKES. MONTHLY PRECIPITATION ENDED UP FROM WELL ABOVE  
NORMAL OVER PORTIONS OF THE SOUTHWEST HALF OF UPPER MICHIGAN TO  
CLOSER TO NORMAL AT MOST PLACES OVER THE NORTHEAST HALF. OVER 5  
INCHES OF RAIN FELL AT SOME LOCATIONS FROM IRONWOOD AND ONTONAGON TO  
IRON MOUNTAIN, INCLUDING THE MONTHLY MAXIMUM OF 6.71 INCHES AT  
WATERSMEET, TOTALS AROUND 200 PERCENT OF THE MAY AVERAGES. IRON  
MOUNTAIN MEASURED THE SEVENTH HIGHEST MAY PRECIPITATION ON RECORD AT  
THAT SIGHT WITH 5.90 INCHES. THERE WAS LESS PRECIPITATION OVER THE  
EAST, WHERE ONLY 2.63 INCHES AND 2.75 INCHES FELL AT MANISTIQUE AND  
NEWBERRY RESPECTIVELY. THESE TOTALS ARE CLOSE TO THE MAY NORMALS FOR  
THOSE LOCATIONS.  
 
SINCE THE UPPER AIR PATTERN FEATURED A TROUGH IN CENTRAL NORTH  
AMERICA MUCH OF THE TIME IN MAY, THE MONTH ENDED UP COOLER THAN  
NORMAL. MEAN MONTHLY TEMPERATURES RANGING FROM AROUND 45 DEGREES  
CLOSE TO THE COOLING INFLUENCE OF LAKE SUPERIOR TO NEAR 52 DEGREES  
AT IRON MOUNTAIN ARE ABOUT 2 TO 4 DEGREES BELOW THE MONTHLY AVERAGES  
AND 6 TO 9 DEGREES HIGHER THAN THE APRIL MEAN TEMPERATURES.  
 
MAY BEGAN ON A CHILLY, WET NOTE AS A DEEP LOW PRESSURE SYSTEM OVER  
THE PLAINS MOVED NORTHEAST INTO THE GREAT LAKES. RAIN AHEAD OF THIS  
LOW OVERSPREAD THE AREA DURING THE NIGHT ON 4/30-5/1. MAXIMUM  
TEMPERATURES HELD IN THE 30S OVER THE COLDER SPOTS ACROSS NORTHWEST  
UPPER MICHIGAN. AS THE LOW SHIFTED TO THE NORTH, NORTHWEST WINDS  
GUSTING AS HIGH AS 35 TO 40 MPH IN ITS WAKE DREW EVEN COLDER AIR  
INTO THE UPPER LAKES TO CHANGE THE PRECIPITATION TO SNOW OVER THE  
HIGHER TERRAIN OF THE NORTHWEST HALF DURING THE EARLY MORNING HOURS  
ON 5/2. BY THE TIME THE PRECIPITATION DIMINISHED DURING THE  
AFTERNOON ON 5/2, 0.25 TO 0.75 INCH OF WATER EQUIVALENT  
PRECIPITATION HAD FALLEN OVER MOST OF THE U.P. IRONWOOD LED  
REPORTING STATIONS WITH A TOTAL OF 1.58 INCHES. BERGLAND DAM IN  
ONTONAGON COUNTY, ATLANTIC MINE IN HOUGHTON COUNTY AND HERMAN IN  
BARAGA COUNTY ALL REPORTED 2 INCHES OF WET SNOW.  
 
A VERY ACTIVE WEATHER PATTERN PREVAILED ACROSS THE WESTERN GREAT  
LAKES ON 5/15 THROUGH 5/18 AS DISTURBANCES EMBEDDED IN A SOUTHWEST  
FLOW ALOFT BETWEEN A DEEP TROUGH OVER THE WESTERN STATES AND A RIDGE  
ACROSS THE EAST MOVED OVER A SLOW MOVING FRONTAL BOUNDARY. THESE  
DISTURBANCES INTERACTED WITH THE WARM AND MOIST AIRMASS ON THE WARM  
SIDE OF THE FRONT TO CAUSE EPISODES OF SHOWERS AND SOME  
THUNDERSTORMS. THERE WERE INSTANCES OF VERY HEAVY RAIN, ESPECIALLY  
DURING THE NIGHT ON 5/17-5/18, WHEN SOME MINOR FLOODING OCCURRED AT  
SOME LOCATIONS OVER THE WEST AND SOUTH CENTRAL. AS MUCH AS 3.45  
INCHES AND 2.47 INCHES OF RAIN FELL AT WATERSMEET IN GOGEBIC COUNTY  
AND PAULDING IN ONTONAGON COUNTY RESPECTIVELY ON 5/17 THROUGH  
DAYBREAK ON 5/18. THE STRONGEST THUNDERSTORM ALSO DROPPED NICKEL-  
SIZED HAIL NEAR ESCANABA. ON 5/18, GUSTY NORTH WINDS TO 35 TO 45 MPH  
FOLLOWING THE LOW PRESSURE SYSTEM ASSOCIATED WITH THE LAST OF THE  
DISTURBANCES BLEW COLDER AIR INTO UPPER MICHIGAN, CAUSING THE RAIN  
TO MIX WITH SNOW OVER THE HIGHER TERRAIN OF THE NORTHWEST HALF  
BEFORE THE PRECIPITATION ENDED BY LATE IN THE DAY. THE RAINFALL  
TOTAL FROM 5/15 THROUGH 5/18 EXCEEDED AN INCH AT MOST PLACES AND WAS  
AS MUCH AS 5.03 INCHES AT WATERSMEET. IN GENERAL, THE HEAVIEST RAINS  
FELL OVER THE WESTERN U.P. AND THE LEAST OVER THE SOUTHEAST, WHERE  
MENOMINEE AND MANISTIQUE PICKED UP ONLY A LITTLE OVER 0.50 INCH  
DURING THESE 3 TO 4 DAYS.  
 
MORE TO COME LATER.

JUNE FORECAST  
 
THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING EQUAL CHANCES OF  
AN ABOVE AND BELOW NORMAL MONTHLY MEAN TEMPERATURE AND PRECIPITATION  
ACROSS ALL OF UPPER MICHIGAN IN JUNE 2017.  
 
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 12:24 AM 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 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 JULY THROUGH SEPTEMBER 2017.
