                           APRIL FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING A GREATER THAN
CLIMATOLOGICAL CHANCE OF A BELOW NORMAL MONTHLY MEAN TEMPERATURE IN
APRIL 2016 OVER THE NORTHEAST HALF OF UPPER MICHIGAN. OVER THE
SOUTHWEST HALF...THE CPC INDICATES EQUAL CHANCES OF AN ABOVE AND
BELOW NORMAL MONTHLY AVERAGE TEMPERATURE. THE CPC FORECASTS A
GREATER THAN CLIMATOLOGICAL CHANCE OF BELOW NORMAL MONTHLY
PRECIPITATION OVER ALL OF UPPER MICHIGAN IN APRIL EXCEPT FOR THE FAR
EAST...WHERE THE CPC INDICATES EQUAL CHANCES OF ABOVE AND BELOW
NORMAL MONTHLY PRECIPITATION.

                          APRIL CLIMATOLOGY

AS THE SUN CONTINUES ITS MARCH NORTHWARD DURING THE FOURTH MONTH OF
THE YEAR...DAYLIGHT AND AVERAGE TEMPERATURES INCREASE STEADILY. THE
DAILY POSSIBLE SUNSHINE INCREASES FROM 769 MINUTES ON 4/1 TO 860
MINUTES ON THE LAST DAY OF THE MONTH. ON 4/1...NORMAL MAXIMUM AND
MINIMUM TEMPERATURES AT THE MARQUETTE NWS ARE 41 AND 21...BUT
REBOUND TO 55 AND 35 ON 4/30. MONTHLY AVERAGE TEMPERATURES
THROUGHOUT UPPER MICHIGAN ARE 12 TO 14 DEGREES HIGHER IN APRIL THAN
IN MARCH. THE RELATIVELY COOL WATERS OF THE GREAT LAKES OFTEN KEEP
TEMPERATURES NEAR THE SHORE DURING THE DAY MUCH LOWER THAN FARTHER
INLAND.

AVERAGE PRECIPITATION IN APRIL IS GREATER THAN IN MARCH OVER MUCH OF
INTERIOR UPPER MICHIGAN...BUT GENERALLY LESS IN AREAS NEAR LAKE
SUPERIOR AS THE RELATIVELY COOL WATERS INCREASE LOW LEVEL STABILITY
AND REDUCE THE THREAT OF LAKE EFFECT SNOW AND CONVECTIVE SHOWERS.
SNOWFALL DURING WARM AND/OR DRY APRILS ACROSS UPPER MICHIGAN IS
OFTEN LESS THAN AN INCH.

SUMMER-LIKE WEATHER CAN OCCUR DURING APRIL. RECORD HIGH TEMPERATURES
NEAR THE END OF THE MONTH GO ABOVE 90 IN SOME LOCATIONS...INCLUDING
THE 94 AND 92 DEGREE READINGS OBSERVED AT IRON MOUNTAIN AND THE
MARQUETTE NWS ON 4/22/80. ALTHOUGH APRIL 1987 IS THE WARMEST ON
RECORD OR AT LEAST IN THE TOP FIVE WARMEST AT MANY PLACES...THE
SECOND HALF OF APRIL 1990 STANDS OUT AS A PERIOD OF UNPRECEDENTED
WARMTH. IN FACT...THE WEEK BETWEEN 4/22/90 AND 4/29/90 IS THE
WARMEST ON RECORD AT ALL REPORTING STATIONS. TEMPERATURES DURING
THIS WEEK AVERAGED AS HIGH AS 68 AT MUNISING AND THE MARQUETTE
NWS...67 AT ONTONAGON...65 AT IRON MOUNTAIN...IRONWOOD AND
MANISTIQUE...64 AT HOUGHTON AND 62 AT NEWBERRY. AT MANY OF THESE
SITES... THE HIGHEST APRIL TEMPERATURE ON RECORD OCCURRED DURING
THIS WEEK...INCLUDING 89 AT MUNISING (4/26/90) AND ONTONAGON
(4/25/90)...88 AT HOUGHTON (4/25/90)...84 AT MANISTIQUE (4/26/90)
AND 82 AT NEWBERRY (4/25/90). SEVEN OF THE 10 HIGHEST APRIL MAXIMUM
TEMPERATURES RECORDED AT MANISTIQUE OCCURRED BETWEEN 4/23/90 AND
4/29/90. ALL OF THESE TEMPERATURES WOULD BE CONSIDERED NORMAL OR
EVEN ABOVE NORMAL DURING MID SUMMER.

WHEN APRIL TEMPERATURES SOAR QUICKLY WITH LINGERING DEEP WINTER SNOW
COVER...SNOWMELT CAN CAUSE SERIOUS FLOODING...ESPECIALLY IF HEAVY
RAINS FALL AROUND THE TIME OF WARMUP. IN 2002...THE COMBINATION OF
DEEP EARLY APRIL SNOW COVER AND A FEW DAYS OF HEAVY RAIN BEFORE
TEMPERATURES WARMED AS HIGH AS 80 TO 85 CAUSED DISASTROUS MID-APRIL
FLOODING IN WESTERN UPPER MICHIGAN. THE FLOODING WAS SO BAD IN
GOGEBIC COUNTY THEN MICHIGAN GOVERNOR JOHN ENGLER DECLARED THAT
COUNTY A DISASTER AREA AND DISPATCHED MICHIGAN NATIONAL GUARD TROOPS
TO ASSIST WITH RECOVERY. ALTHOUGH SEVERE WEATHER IS UNCOMMON ACROSS
UPPER MICHIGAN IN APRIL...AN OUTBREAK OF EARLY SEASON SEVERE
THUNDERSTORMS ENDED THIS PREMATURE SUMMER WARMTH IN APRIL 2002.

ALTHOUGH AVERAGE TEMPERATURES CLIMB QUICKLY IN APRIL AND SUMMER-LIKE
HEAT SOMETIMES HERALDS THE COMING WARM SEASON...WINTER CAN RETURN
WITH A VENGEANCE EVEN AT MONTHS END. FOR STATIONS WITH A LONGER TERM
RECORD...APRIL 1907 STANDS OUT AS THE COLDEST ON RECORD AT IRONWOOD
AND HOUGHTON. AT HOUGHTON...THE MEAN MONTHLY TEMPERATURE THAT MONTH
WAS A WINTER-LIKE 27.9 DEGREES. APRIL 1950 WAS THE COLDEST FOURTH
MONTH ON RECORD AT NEWBERRY...IRON MOUNTAIN AND MUNISING. MORE
RECENTLY...APRIL IN 2013 AND 2014 FEATURED PERIODS OF VERY COLD
WEATHER AND RANK AMONG THE TOP FIVE COLDEST AT SOME PLACES. RECORD
LOW TEMPERATURES IN APRIL ARE BELOW ZERO AT MOST LOCATIONS. THE
MERCURY FELL AS LOW AS -12 AT IRONWOOD ON 4/7/82. SUB-ZERO MINIMUMS
HAVE OCCURRED EVEN AFTER MID MONTH AT SOME LOCATIONS...INCLUDING -8
AT IRONWOOD ON 4/17/83 AND -7 AT CLARKSBURG/CHAMPION IN MARQUETTE
COUNTY ON 4/16/2014.

RECORD HIGH APRIL SNOWFALL AT ALMOST ALL LOCATIONS EXCEPT THE
SOUTHERN TIER COUNTIES IS 20 INCHES OR MORE. A HISTORIC BLIZZARD
STRUCK THE NORTHERN COUNTIES OF UPPER MICHIGAN ON 4/3 INTO 4/8 IN
2007. THE COMBINATION OF LAKE ENHANCED SNOW AND NORTH WIND GUSTS AT
OR ABOVE 50 MPH CAUSED WIDESPREAD BLIZZARD CONDITIONS ON 4/4 AND 4/5
THAT YEAR NEAR LAKE SUPERIOR. BY THE TIME THE SNOW ENDED EARLY ON
4/8/2007...AS MUCH AS 59.0 INCHES HAD FALLEN AT PAINESDALE IN
HOUGHTON COUNTY. IN APRIL 2013...A PERSISTENT AND DEEP UPPER TROUGH
OVER CENTRAL AND EASTERN NORTH AMERICA RESULTED IN STUBBORN CHILL
UNTIL THE LAST WEEK OF THE MONTH AND SEVERAL HEAVY SNOW FALLS THAT
PUSHED THE MONTHLY SNOWFALL TO RECORD LEVELS AT OR ABOVE 50 INCHES
AT SEVERAL LOCATIONS OVER WESTERN UPPER MICHIGAN. MOST LOCATIONS
ENDURED TOP TEN APRIL SNOWFALL IN 2013. APRIL 2014 ALSO FEATURED
SOME HEAVY SNOWFALL THAT PLACED THE MONTH IN THE LIST OF TOP FIVE
SNOWIEST APRILS ON RECORD AT SOME SPOTS.

               OUTLOOK FOR LATE SPRING INTO SUMMER
