...GREAT LAKES WATER LEVELS REMAIN NEARLY STEADY IN MARCH...

DUE TO THE RECORD COLD WEATHER IN DECEMBER THROUGH MARCH...LAKE
SUPERIOR AND MUCH OF NORTHERN LAKE MICHIGAN WERE ALMOST COMPLETELY
ICE COVERED THROUGH MARCH. THE EXTENSIVE ICE COVER AND A NEAR
ABSENCE OF EVAPORATION IN THE PERSISTENTLY COLD WEATHER PATTERN
CAUSED THE LAKES TO REMAIN NEARLY STEADY THROUGH THE MONTH. AT THE
END OF MARCH...LAKES MICHIGAN/HURON WERE STILL ALMOST 13 INCHES
UNDER THE LONG TERM AVERAGE...WHILE LAKE SUPERIOR WAS AT A NEAR
NORMAL LEVEL. COMPARED TO THE END OF MARCH IN 2013...THE LEVEL ON
LAKES MICHIGAN/HURON WAS ABOUT 13 INCHES HIGHER ON 3/31 IN 2014.
LAKE SUPERIOR WAS ALSO ABOUT 13 INCHES HIGHER IN MARCH 2014 AS IN
2013.

                           APRIL FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING A GREATER THAN
CLIMATOLOGICAL CHANCE OF A BELOW NORMAL MONTHLY MEAN TEMPERATURE BUT
AN EQUAL CHANCE OF ABOVE AND BELOW NORMAL MONTHLY PRECIPITATION OVER
ALL OF UPPER MICHIGAN IN APRIL 2014.

                         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. RECORD HIGH MONTHLY 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 10 APRIL SNOWFALL
IN 2013. THE MERCURY HAS FALLEN AS LOW AS -12 AT IRONWOOD
(4/7/82)...-9 AT THE MARQUETTE NWS (4/6/2003)...-7 AT MANISTIQUE
(4/5/72)...-6 AT IRON MOUNTAIN (4/5/72)...-4 AT MUNISING (4/6/50)...
-2 AT NEWBERRY (4/1/23) AND ZERO AT HOUGHTON (4/4/54) AND ONTONAGON
(4/7/96). IRONWOOD HAS REPORTED TEMPERATURES WELL BELOW ZERO EVEN
AFTER MID MONTH...-8 AND -5 ON 4/17/83 AND 4/18/83 RESPECTIVELY.
APRIL 1995 AND 1996 WERE NOTORIOUSLY COLD ACROSS UPPER MICHIGAN WITH
TEMPERATURES AVERAGING FIVE DEGREES OR MORE BELOW NORMAL...AND MANY
PLACES COUNT THESE MONTHS IN THE TOP FIVE COLDEST APRILS ON RECORD.
APRIL 1950 STANDS OUT AS VERY CHILLY AT STATIONS WITH A LONGER
CLIMATE RECORD. THAT MONTH IS THE COLDEST APRIL AT NEWBERRY (AVERAGE
TEMPERATURE OF 29.9)...IRON MOUNTAIN (32.3) AND MUNISING (31.3) AND
IN THE TOP FIVE COLDEST AT IRONWOOD (31.0) AND MANISTIQUE (33.0).
