                       APRIL WEATHER SUMMARY

MORE TO COME LATER.

                           MAY 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
MAY 2016.

                          MAY CLIMATOLOGY

MAY BRINGS A CONTINUED MODERATION IN TEMPERATURE AS DAYLIGHT
CONTINUES TO LENGTHEN. POSSIBLE SUNSHINE INCREASES FROM 863 MINUTES
ON 5/1 TO 932 MINUTES ON 5/31. THE AVERAGE TEMPERATURE IN MAY IS 12
TO 13 DEGREES HIGHER THAN IN APRIL. ALTHOUGH AVERAGE HIGH
TEMPERATURES REACH AROUND 70 BY MEMORIAL DAY OVER INLAND AREAS...
THE RELATIVELY COLD WATERS OF THE GREAT LAKES OFTEN KEEP SHORE
COMMUNITIES UP TO 20 DEGREES COOLER IN THE AFTERNOON. MORNING
TEMPERATURES FREQUENTLY SLIP BELOW FREEZING AT THE BEGINNING OF
MAY...BUT AVERAGE LOW TEMPERATURES RISE ABOVE 40 AFTER MID MONTH.

THE INCREASE IN AVERAGE TEMPERATURE RESULTS IN A GREATER THREAT OF
SHOWERS AND THUNDERSTORMS. AVERAGE PRECIPITATION IS 10 TO 40 PERCENT
HIGHER THAN IN APRIL...WITH THE GREATEST AMOUNTS MOST LIKELY NEAR
THE WISCONSIN BORDER WHERE THE STABILIZING INFLUENCE OF THE GREAT
LAKES IS LESS.

MAY IS GENERALLY A TEMPERATE MONTH...BUT WINTER CHILL IS STILL
POSSIBLE. ALTHOUGH AVERAGE TEMPERATURES RISE SHARPLY...FROST OFTEN
OCCURS AT THE END OF MAY AS RECORD LOW TEMPERATURES REMAIN BELOW
FREEZING THE ENTIRE MONTH AT MANY LOCATIONS. NEWBERRY SAW THE
MERCURY PLUNGE ALL THE WAY TO 19 AS LATE AS 5/24...IN 1925. MAY 1997
GOES DOWN IN THE RECORD BOOKS AS ONE OF THE COLDEST EVER AT ALL
REPORTING STATIONS WITH MONTHLY TEMPERATURES AS MUCH AS SEVEN TO
EIGHT DEGREES BELOW NORMAL. IN FACT...THIS MONTH IS THE COLDEST
FIFTH MONTH EVER AT MANISTIQUE (AVERAGE TEMPERATURE 44.4)...IRON
MOUNTAIN (45.9) AND ONTONAGON (46.6) AS WELL AS IN THE TOP TEN
COLDEST AT MOST OTHER UPPER MICHIGAN LOCATIONS. EVEN MORE
RECENTLY...MAY 2002 LANDED IN THE LIST OF TOP TEN COLDEST. MONTHLY
TEMPERATURES IN MAY 2002 AVERAGED 5 TO 7 DEGREES BELOW NORMAL AT
MOST SITES. AT MUNISING...THE MERCURY AVERAGED 9 DEGREES BELOW
NORMAL (41.5) AND THE MONTH GOES DOWN IN THE RECORD BOOKS AS THE
COLDEST MAY EVER. AT STATIONS WITH A LONGER TERM RECORD...MAY 1954
STANDS OUT AS VERY CHILLY...IN FACT THE COLDEST EVER AT THE HOUGHTON
COUNTY AIRPORT (41.8)...WHEN MONTHLY TEMPERATURES FELL OVER EIGHT
DEGREES BELOW NORMAL.

SNOW CAN STILL PLAGUE UPPER MICHIGAN DURING MAY. A LATE SEASON
SNOWSTORM OCCURRED IN CENTRAL UPPER MICHIGAN ON 5/9-5/10/90...WHEN
AN IMPRESSIVE 22.4 INCHES OF HEAVY WET SNOW FELL AT THE MARQUETTE
NWS...11 INCHES BLANKETED IRON MOUNTAIN...AND 7 INCHES FELL ON
MUNISING. DURING THE CHILLY MAY 1997...13 INCHES OF THE WHITE STUFF
ACCUMULATED AT ONTONAGON ON 5/12 AND 11.3 INCHES SMOTHERED IRONWOOD.
NEWBERRY WAS STRUCK BY AN EVEN LATER MAY SNOWSTORM...10 INCHES
ACCUMULATED THERE ON 5/23 AND 5/24 BACK IN 1917. MEASURABLE SNOW AS
LATE AS MEMORIAL DAY IS NOT UNPRECEDENTED...IRONWOOD RECORDED 3.7
INCHES OF SNOW ON 5/28/65.

ALTHOUGH SNOW CAN STILL FALL IN MAY...SPRING HEAT WAVES CAN ALSO
BRING MID SUMMER HEAT TO UPPER MICHIGAN. ON 5/31 IN 1934...BOTH IRON
MOUNTAIN AND IRONWOOD RECORDED MONTHLY RECORD 100 DEGREE HIGH
TEMPERATURES. RECORD HIGH TEMPERATURES ARE IN THE 90S EVERYWHERE BY
MONTHS` END...EXCEPT AT MANISTIQUE WHERE A SOUTHERLY FLOW OFF LAKE
MICHIGAN OFTEN KEEPS AFTERNOON MAXIMUM TEMPERATURES FROM GETTING AS
HIGH AS FARTHER INLAND. MAY 1977 AND 1998 ARE THE WARMEST MAYS IN
RECENT MEMORY. MAY 1977 IS THE WARMEST ON RECORD AT IRON MOUNTAIN
(62.4)...THE MARQUETTE NWS (59.4)...THE HOUGHTON COUNTY AIRPORT
(58.1) AND MUNISING (57.5). MAY 1998 GOES DOWN IN THE RECORD BOOKS
AS THE WARMEST ON RECORD AT NEWBERRY (59.1) AND IN THE TOP FIVE
WARMEST AT MANY OTHER PLACES. MAY 2000 SAW A VERY SUMMERLIKE WEEK IN
THE EARLY PART OF THE MONTH...AND TEMPERATURES AVERAGED 20 DEGREES
ABOVE NORMAL AT MANY LOCATIONS BETWEEN 5/3 AND 5/8. BARAGA SAW THE
MERCURY REACH 90 ON 5/5/2000...AND THE MARQUETTE NWS BROKE FOUR
DAILY RECORD HIGH TEMPERATURES DURING THAT 6-DAY STRETCH. IN FACT...
THE WEEK BETWEEN 5/3/00 AND 5/8/00 IS THE WARMEST 6-DAY PERIOD ON
RECORD IN EARLY MAY AT THE MARQUETTE NWS. MORE RECENTLY...MAY 2010
FEATURED A MEAN MONTHLY AVERAGE TEMPERATURE 3 TO 5 DEGREES ABOVE
NORMAL.

                        OUTLOOK FOR SUMMER

THE CLIMATE PREDICTION CENTER (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 JUNE THROUGH AUGUST 2016.
