...GREAT LAKES WATER LEVELS WELL ABOVE NORMAL AGAIN IN APRIL...

AS IS NORMAL...GREAT LAKES WATER LEVELS ROSE IN APRIL 2015 DUE TO
SNOW MELT RUNOFF. LINGERING ICE COVER AND COLD WATER WHICH LIMITED
EVAPORATION ALSO OFFSET RECENT DRYNESS. AT THE END OF APRIL...WATER
LEVELS ON LAKE SUPERIOR WERE 8 TO 9 INCHES ABOVE NORMAL. THE LEVEL
ON LAKES MICHIGAN AND HURON WAS 7 TO 8 INCHES ABOVE AVERAGE ON 4/30
AND ALMOST 20 INCHES HIGHER THAN DURING APRIL 2014. AS FOR LAKE
SUPERIOR...THE 4/30 LEVEL OF THAT BODY OF WATER WAS OVER 8 INCHES
HIGHER THAN OBSERVED IN APRIL A YEAR AGO.

AT THE BEGINNING OF APRIL...MUCH OF CENTRAL AND EASTERN LAKE
SUPERIOR WERE COVERED BY EXTENSIVE ICE...WHILE MOST OF THE WESTERN
PART OF THE LAKE WAS ICE FREE. THICK ICE REMAINED OVER NORTHEAST
LAKE MICHIGAN EAST OF A LINE FROM ABOUT MANISTIQUE TO THE LEELANAU
PENINSULA. FRAGMENTED ICE LINGERED OVER THE BAY OF GREEN BAY. DUE TO
THE VERY WARM WEATHER THAT DEVELOPED DURING THE SECOND WEEK OF
APRIL...THE ICE BEGAN TO MELT STEADILY. ON 4/15...MOST OF THE BAY OF
GREEN BAY WAS ICE FREE...AND REMAINING ICE ON LAKE MICHIGAN WAS
CONFINED TO AREAS ALONG MACKINAC COUNTY AND THE FAR NORTHWEST LOWER
PENINSULA UP TO THE MACKINAC BRIDGE. THE MOST EXTENSIVE ICE COVER ON
LAKE SUPERIOR WAS NEAR THE NORTHERN TIP OF THE KEWEENAW PENINSULA
AND OVER THE FAR EASTERN END OF THE LAKE. AT THE END OF APRIL...
SIGNIFICANT ICE WAS PRESENT OVER ONLY FAR EASTERN LAKE SUPERIOR. THE
BAY OF GREEN BAY AND NORTHERN LAKE MICHIGAN WERE ICE FREE.

                        APRIL CLIMATE HIGHLIGHTS

HIGHEST REPORTED TEMPERATURE...76 AT PELKIE IN BARAGA COUNTY AND
                                JACOBSVILLE IN HOUGHTON COUNTY ON
                                4/12 AND IRON MOUNTAIN ON 4/17

LOWEST REPORTED TEMPERATURE...3 NEAR NEWBERRY ON 4/4

HIGHEST AVERAGE TEMPERATURE...41.5 DEGREES AT FORD AIRPORT NEAR IRON
                               MOUNTAIN

LOWEST AVERAGE TEMPERATURE...35.6 DEGREES AT HERMAN IN BARAGA COUNTY

HIGHEST MONTHLY PRECIPITATION...3.31 INCHES AT HERMAN

LOWEST MONTHLY PRECIPITATION...0.98 INCH AT BARAGA

HIGHEST MONTHLY SNOWFALL...17.3 INCHES AT HERMAN

LOWEST MONTHLY SNOWFALL...1.0 INCH AT MANISTIQUE

GREATEST SNOW DEPTH...41 INCHES NEAR GRAND MARAIS IN ALGER COUNTY
                       ON 4/1

A CHANGEABLE UPPER AIR PATTERN DOMINATED THE WEATHER OVER THE GREAT
LAKES IN APRIL. SINCE THE POSITIVE TEMPERATURE ANOMALIES THAT
OCCURRED WHEN A RIDGE OR PACIFIC FLOW WERE PRESENT NEARLY BALANCED
OUT THE NEGATIVE TEMPERATURE FLUCTUATIONS WHEN A TROUGH WAS OVER THE
AREA...THE MEAN MONTHLY TEMPERATURE ENDED UP WITHIN A DEGREE OR SO
OF NORMAL ACROSS THE WEST HALF OF UPPER MICHIGAN. BUT SINCE A GOOD
DEAL OF ICE LINGERED OVER EASTERN LAKE SUPERIOR AND NORTHEAST LAKE
MICHIGAN DURING APRIL...OVERALL TEMPERATURES WERE HELD DOWN OVER THE
ADJOINING EAST HALF OF THE UPPER PENINSULA...WHERE THE MEAN MONTHLY
TEMPERATURE WAS 1 TO AS MUCH AS 3 DEGREES BELOW AVERAGE AT MUNISING.
THE AVERAGE APRIL TEMPERATURE BETWEEN ABOUT 35 AND 42 DEGREES WAS 12
TO 17 DEGREES HIGHER THAN THE MARCH MEAN TEMPERATURE.

THE THERMOMETER DIPPED INTO THE SINGLE NUMBERS ABOVE ZERO ONLY AT A
FEW SPOTS OVER THE EAST HALF ON 4/4 DURING A COLD AIR OUTBREAK THE
FIRST WEEK OF APRIL. THERE WAS ANOTHER COLD AIR OUTBREAK DURING THE
FOURTH WEEK OF THE MONTH. THE DAY ON 4/22 WAS PARTICULARLY CHILLY
AND FEATURED SOME DAILY RECORD LOW MAXIMUM TEMPERATURES IN THE 20S.
SOME DAILY RECORD LOW MINIMUM TEMPERATURES IN THE TEENS OCCURRED
DURING THE MORNINGS ON 4/24 AT MANY INTERIOR PLACES AND 4/25 AT A
FEW OF THE COLDER SPOTS OVER THE INTERIOR EAST UNDER THE DOMINATION
OF CANADIAN HIGH PRESSURE.

THE WARMEST WEATHER IN APRIL WAS NEAR MID MONTH WHEN AN UPPER RIDGE
DOMINATED THE WEATHER PATTERN IN THE GREAT LAKES. THIS MID-MONTH
WARM STRETCH TENDED TO MELT MUCH OF THE LINGERING SNOW PACK EXCEPT
AT SOME LOCATIONS OVER THE EAST...WHERE LINGERING ICE ON THE
SURROUNDING GREAT LAKES MITIGATED THE WARMUP. THE MERCURY REACHED
THE 70S ON 4/12...4/15...4/16 AND 4/17 AT AT LEAST A COUPLE OF
LOCATIONS MAINLY OVER THE WEST HALF. SOME DAILY RECORD HIGH MINIMUM
READINGS IN THE 40S WERE OBSERVED DURING THE MORNING ON 4/12 UNDER A
STRONG SOUTHWEST FLOW BETWEEN DEPARTING HIGH PRESSURE OVER THE MID
ATLANTIC STATES AND A COLD FRONT PUSHING THROUGH THE NORTHERN PLAINS.

THE GENERALLY DRY WEATHER PATTERN THAT HAS DOMINATED 2015 WEATHER IN
THE UPPER GREAT LAKES CONTINUED IN APRIL. ALTHOUGH THERE WERE FEW
LARGER SCALE PRECIPITATION EVENTS...THE ONE SIGNIFICANT LOW PRESSURE
SYSTEM THAT MOVED THROUGH THE WESTERN GREAT LAKES ON 4/9 AND 4/10
DID DROP SOME LOCALLY HEAVY MIXED PRECIPITATION OVER MAINLY CENTRAL
UPPER MICHIGAN. AS A RESULT...APRIL PRECIPITATION AND SNOWFALL WERE
NOT MUCH BELOW NORMAL...AND EVEN ABOVE NORMAL AT SOME LOCATIONS...
ACROSS THIS AREA. BUT THE PLACES OVER THE EAST AND WEST THAT TENDED
TO MISS OUT ON THE BULK OF THE WEATHER THAT OCCURRED DURING THE 4/9
INTO 4/10 EVENT RECORDED BELOW NORMAL APRIL PRECIPITATION AND
SNOWFALL. HERMAN OVER THE HIGHER TERRAIN OF THE HURON MOUNTAINS IN
BARAGA COUNTY REPORTED BOTH THE HIGHEST APRIL PRECIPITATION AND
SNOWFALL WITH 3.31 INCHES AND 17.3 INCHES RESPECTIVELY. SINCE SOME
LOCATIONS OVER THE CENTRAL NEAR THE WISCONSIN BORDER SAW A GOOD DEAL
OF SNOW DURING THIS STORM AND ALSO DURING ANOTHER MORE LOCALIZED
EVENT THAT OCCURRED IN THE MORNING ON 4/6...MONTHLY SNOWFALL AROUND
10 INCHES IN THIS AREA WAS AS MUCH AS 200 PERCENT OF NORMAL. AT
NEWBERRY...THE APRIL PRECIPITATION AND SNOWFALL TOTALS OF 1.27
INCHES AND 1.3 INCHES ARE ONLY 57 PERCENT AND 18 PERCENT OF THE
APRIL AVERAGES.

A BAND OF MODERATE TO LOCALLY HEAVY SNOW MOVED ACROSS SOUTH CENTRAL
UPPER MICHIGAN DURING THE MORNING ON 4/6 WELL TO THE NORTH OF A WARM
FRONT OVER THE LOWER GREAT LAKES. AS MUCH AS 7 INCHES OF WET SNOW
FELL AT HERMANSVILLE AND POWERS IN CENTRAL MENOMINEE COUNTY.

A LOW PRESSURE SYSTEM UNDER A DEEPENING UPPER TROUGH IN THE PLAINS
BROUGHT A SIGNIFICANT WINTRY MIX OF PRECIPITATION TO THE UPPER
PENINSULA ON 4/9 INTO 4/10. AS MUCH AS 1.50 INCHES OF WATER
EQUIVALENT PRECIPITATION AND NEARLY 10 INCHES OF SNOW FELL OVER THE
NORTH CENTRAL. NORTHWEST WINDS GUSTED AS HIGH AS 45 MPH ON 4/10 NEAR
LAKE SUPERIOR AS THE INTENSIFYING LOW PRESSURE SYSTEM EXITED INTO
ONTARIO.

ANOTHER DEEP UPPER TROUGH DOMINATED THE WEATHER PATTERN OVER THE
GREAT LAKES ON 4/20 INTO 4/23. AN INITIAL LOW PRESSURE SYSTEM
TRACKED THROUGH LOWER MICHIGAN ON 4/20...CAUSING WIDESPREAD RAIN
OVER THE UPPER PENINSULA. COLDER AIR THEN FOLLOWED INTO THE UPPER
LAKES ON THE HEELS OF GUSTY NORTHWEST WINDS LEFT IN THE WAKE OF THIS
LOW...WHICH STALLED JUST SOUTHWEST OF JAMES BAY INTO 4/22. LINGERING
RAIN SHOWERS BECAME MORE NUMEROUS AT TIMES AND MIXED WITH OR CHANGED
TO SNOW AS DISTURBANCES ROTATED THROUGH THE UPPER TROUGH AND
INTERACTED WITH THE COLDER AIR. THE CORE OF THE COLD AIR MOVED
OVERHEAD ON 4/22...WHEN MANY LOCATIONS OBSERVED A DAILY RECORD LOW
MAXIMUM TEMPERATURE. AS MUCH AS 6 TO 10 INCHES OF WET SNOW
ACCUMULATED OVER THE HIGHER TERRAIN OF THE WEST AND NORTH CENTRAL ON
4/20 INTO 4/23. BESSEMER IN GOGEBIC COUNTY MEASURED 12 INCHES. TOTAL
WATER EQUIVALENT PRECIPITATION DURING THIS TIME REACHED 1.19 INCHES
AT HERMAN IN BARAGA COUNTY AND 1.11 INCHES AT MOHAWK IN KEWEENAW
COUNTY.

                         APRIL WEATHER SUMMARY

APRIL STARTED ON A RELATIVELY WARM NOTE AS THE STRONG SOUTHWEST FLOW
AROUND LOW PRESSURE TRACKING FROM SOUTH CENTRAL CANADA ON 4/1 INTO
NORTHWEST ONTARIO ON 4/2 DREW MILD AIR INTO THE UPPER LAKES. THESE
SOUTHWEST WINDS GUSTED AS HIGH AS 50 MPH OVER THE WEST IN THE EARLY
MORNING HOURS ON 4/2 AND CAUSED SOME DAMAGE. A RADIO TOWER NEAR
BESSEMER IN GOGEBIC COUNTY WAS KNOCKED DOWN BY THESE GUSTY WINDS.
THERE WERE ALSO SOME SCATTERED SHOWERS...MAINLY DURING THE NIGHT ON
4/1-4/2. SOME PLACES MEASURED 0.05 TO 0.15 INCH OF RAIN...BUT AS
MUCH AS 0.37 INCH FELL AT GRAND MARAIS IN ALGER COUNTY. AFTERNOON
TEMPERATURES ON 4/2 ROSE WELL INTO THE 60S AT SOME LOCATIONS ON 4/2
WITH THE RETURN OF MORE SUNSHINE WITHIN THE WARM AIRMASS...BUT WEST
WINDS GUSTING AS HIGH AS 40 TO 50 MPH OVER THE WEST MADE THE AIR
FEEL COOLER. THE THERMOMETER AVERAGED ABOUT 5 DEGREES ABOVE NORMAL
ON APRIL FOOL`S DAY...BUT READINGS PEAKED AS HIGH AS 15 TO 20
DEGREES ABOVE NORMAL ON 4/2.

THE PASSAGE OF A COLD FRONT UNDER A DEEPENING UPPER TROUGH DURING
THE NIGHT ON 4/2-4/3 INTRODUCED MUCH COLDER CANADIAN AIR INTO THE
GREAT LAKES. THE PERIOD FROM 4/3 THROUGH 4/5 FEATURED MEAN DAILY
TEMPERATURES BETWEEN 5 AND 10 DEGREES BELOW NORMAL. WITH CLEAR SKIES
AND LIGHT WINDS ACCOMPANYING THE PASSAGE OF A HIGH PRESSURE RIDGE
ACROSS THE UPPER GREAT LAKES...THE NIGHT OF 4/3-4/4 WAS PARTICULARLY
CHILLY AND FEATURED LOW TEMPERATURES IN THE SINGLE DIGITS ABOVE ZERO
AT A FEW OF THE COLD SPOTS OVER THE INTERIOR EAST HALF. SOME
GENERALLY LIGHT SNOW SHOWERS ACCOMPANIED THE PASSAGE OF THE COLD
FRONT EARLY ON 4/3 AND ANOTHER ALBERTA CLIPPER TYPE DISTURBANCE ON
4/4...BUT ANY SNOW ACCUMULATION WAS UNDER AN INCH. EASTER SUNDAY ON
4/5 WAS PARTLY TO MOSTLY SUNNY AND CHILLY. MANY LOCATIONS OVER THE
NORTH CENTRAL AND EAST REPORTED HIGH TEMPERATURES NO HIGHER THAN 25
TO 32.

A BAND OF MODERATE TO LOCALLY HEAVY SNOW MOVED ACROSS SOUTH CENTRAL
UPPER MICHIGAN DURING THE MORNING ON 4/6 WELL TO THE NORTH OF A WARM
FRONT OVER THE LOWER GREAT LAKES. AS MUCH AS 4 TO 7 INCHES OF WET
SNOW FELL FROM SOUTHERN DICKINSON COUNTY ACROSS CENTRAL MENOMINEE
COUNTY AND IN DELTA COUNTY SOUTH OF ESCANABA. HERMANSVILLE AND
POWERS IN MENOMINEE COUNTY LED REPORTING STATIONS WITH 7 INCHES OF
SNOW. THERE WAS NO PRECIPITATION OVER THE NORTHERN TIER COUNTIES
CLOSER TO DRY HIGH PRESSURE IN ONTARIO. AFTER LINGERING SNOW OVER
THE SOUTH CENTRAL ENDED BY NOON ON 4/6...THE HIGH PRESSURE DRIFTING
ACROSS ONTARIO BROUGHT A PERIOD OF DRY WEATHER THROUGH 4/7. A
DISTURBANCE RIDING ALONG THE STATIONARY FRONT TO THE SOUTH DROPPED
SOME LIGHT MIXED PRECIPITATION MAINLY NEAR THE WISCONSIN BORDER
DURING THE NIGHT OF 4/7-4/8 AND INTO THE MORNING ON 4/8. ANY
PRECIPITATION AND SNOW WERE NO MORE THAN ABOUT 0.10 INCH AND 1.0
INCH RESPECTIVELY. MEAN DAILY TEMPERATURES ROSE FROM ABOUT 5 DEGREES
BELOW AVERAGE ON 4/6 TO ABOUT NEAR NORMAL ON 4/8.

AS AN UPPER TROUGH BEGAN TO DEVELOP IN THE PLAINS ON 4/8...SOME
LIGHT RAIN...FREEZING RAIN AND SNOW DEVELOPED OVER UPPER MICHIGAN IN
THE EARLY MORNING HOURS ON 4/9 TO THE NORTH OF A WARM FRONT IN THE
LOWER GREAT LAKES. THIS MIXED PRECIPITATION CHANGED TO MAINLY RAIN
BY AFTERNOON ON 4/9. AS INTENSIFYING LOW PRESSURE UNDER THE
DEEPENING TROUGH MOVED NORTHEAST THROUGH THE UPPER MIDWEST AND THEN
ACROSS EASTERN UPPER MICHIGAN DURING THE EARLY MORNING HOURS ON
4/10...SOME HEAVIER RAIN OVERSPREAD THE AREA. AN INFLUX OF COLDER
AIR INTO THE UPPER GREAT LAKES CAUSED THE RAIN TO MIX WITH FREEZING
RAIN AGAIN AT SOME LOCATIONS BEFORE CHANGING TO WET SNOW DURING THE
NIGHT ON 4/9-4/10. AS THE LOW MOVED NORTHEAST INTO ONTARIO ON
4/10...THE PRECIPITATION DIMINISHED TO SOME LIGHTER RAIN AND SNOW
SHOWERS. GUSTY NORTHWEST WINDS PEAKED AS HIGH AS 40 TO 45 MPH ON
4/10 ALONG LAKE SUPERIOR EAST OF THE KEWEENAW BEHIND THE DEPARTING
LOW PRESSURE SYSTEM. CENTRAL UPPER MICHIGAN PICKED UP THE HEAVIEST
PRECIPITATION AND SNOWFALL DURING THIS EVENT...WITH 1.00 TO ABOUT
1.50 INCHES OF LIQUID EQUIVALENT PRECIPITATION FALLING ON 4/9
THROUGH 4/10 IN A SWATH FROM IRON RIVER AND BARAGA TO ESCANABA AND
MUNISING. MANY LOCATIONS OVER THE HIGHER TERRAIN OF THE NORTH
CENTRAL PICKED UP 6 INCHES OF MORE OF SNOW...WITH AS MUCH AS 9.5
INCHES FALLING AT NEGAUNEE IN MARQUETTE COUNTY. AT LEAST 2 TO 4
INCHES OF THE WHITE STUFF ACCUMULATED OVER THE NORTHWEST HALF OF
UPPER MICHIGAN. THE FAR WEST AND EAST SAW THE LEAST PRECIPITATION...
WITH NO MORE THAN ABOUT 0.50 INCH FALLING AT NEWBERRY AND FROM
IRONWOOD TO ONTONAGON BEFORE THE THE WEATHER TURNED DRY IN THE
EVENING ON 4/10. NO MORE THAN ABOUT AN INCH OF SNOW FELL DURING THIS
EVENT FROM MENOMINEE TO ESCANABA...MANISTIQUE AND NEWBERRY. MEAN
DAILY TEMPERATURES ON 4/9 AND 4/10 WERE UP TO 5 DEGREES BELOW
AVERAGE.

HIGH PRESSURE TRAILING THE DEPARTING LOW BROUGHT A PERIOD OF MOSTLY
CLEAR WEATHER ON 4/11 AND 4/12. SINCE THE INCOMING AIRMASS WAS
PACIFIC IN ORIGIN...THE RETURN OF SUNSHINE LIFTED THE MEAN DAILY
TEMPERATURE TO AROUND 5 DEGREES ABOVE NORMAL ON 4/11. SOUTHWEST
WINDS GUSTING AS HIGH AS 35 TO 40 MPH ON THE WESTERN FLANK OF THE
HIGH MOVING TO THE EAST BOOSTED THE MERCURY TO AS MUCH AS 20 TO 25
DEGREES ABOVE AVERAGE ON 4/12 AWAY FROM THE MODERATING INFLUENCE OF
LAKE MICHIGAN. SOME LOCATIONS REPORTED DAILY RECORD HIGH MINIMUM
TEMPERATURES IN THE 40S IN THE MORNING OF 4/12. AFTERNOON READINGS
PEAKED AS HIGH AS 76 AT PELKIE IN BARAGA COUNTY AND JACOBSVILLE IN
HOUGHTON COUNTY...BUT TEMPERATURES ROSE NO FURTHER THAN ABOUT 45
NEAR THE LAKE MICHIGAN SHORE ON 4/12. A COLD FRONT CROSSED THE UPPER
GREAT LAKES IN THE MORNING ON 4/13 ACCOMPANIED BY A BAND OF SHOWERS.
MOST PLACES PICKED UP 0.25 TO 0.35 INCH OF RAIN. WEST TO NORTHWEST
WINDS BEHIND THIS FRONTAL PASSAGE GUSTED AS HIGH AS 35 TO 40 MPH AND
DROVE SOMEWHAT COOLER AIR INTO THE AREA. BUT THE MEAN DAILY
TEMPERATURE ON 4/13 STILL AVERAGED 10 DEGREES ABOVE NORMAL WITH THE
RETURN OF SOME SUNSHINE AND PACIFIC AIR.

AN UPPER RIDGE BUILT OVER THE GREAT LAKES ON 4/14 INTO 4/16. DRY AND
RELATIVELY WARM WEATHER PREVAILED UNDER ASSOCIATED SURFACE HIGH
PRESSURE. MEAN DAILY TEMPERATURES ON THESE THREE DAYS RAN 5 TO 15
DEGREES ABOVE NORMAL. ALTHOUGH THE UPPER RIDGE BROKE DOWN LATE ON
4/16 INTO 4/17 AND ALLOWED A WEAK COLD FRONT TO CROSS THE UPPER
LAKES DURING THE NIGHT OF 4/16-4/17...THE DRYNESS OF THE AIRMASS IN
PLACE RESTRICTED ANY PRECIPITATION TO ONLY SOME SPRINKLES OVER THE
WEST HALF. EVEN BEHIND THIS WEAK FRONT...THE MEAN DAILY TEMPERATURE
ON 4/17 REMAINED 5 TO 15 DEGREES ABOVE AVERAGE. ANOTHER DRY COLD
FRONT PASSED DURING THE NIGHT ON 4/17-4/18 AND WAS FOLLOWED BY HIGH
PRESSURE AND A MORE SEASONABLE AIRMASS FOR 4/18...WHEN THE MEAN
DAILY TEMPERATURE RAN NEAR TO A FEW DEGREES ABOVE NORMAL.

A MORE ACTIVE AND COLDER WEATHER PATTERN DEVELOPED ON 4/19 AS
ANOTHER UPPER TROUGH DEEPENED IN CENTRAL NORTH AMERICA. THE FIRST
DISTURBANCE EMBEDDED IN THIS TROUGH MOVED THROUGH MINNESOTA AND
BROUGHT UP TO 0.10 INCH OF RAIN TO MAINLY THE WEST IN THE MORNING ON
4/19. A MORE WIDESPREAD RAIN OVERSPREAD THE U.P. EARLY ON 4/20 AS
LOW PRESSURE MOVED NORTHEAST INTO LOWER MICHIGAN. AS THE LOW
CONTINUED NORTHEAST INTO ONTARIO AND COLDER AIR WRAPPED INTO THE
UPPER LAKES ON THE HEELS OF GUSTY NORTHWEST WINDS UP TO 35 MPH OVER
THE KEWEENAW...THE RAIN CHANGED TO SNOW OVER THE WEST ON 4/20. THIS
PRECIPITATION DIMINISHED IN THE AFTERNOON AND EVENING FOLLOWING THE
EXIT OF THE LOW FARTHER TO THE NORTHEAST. BUT MORE SNOW SHOWERS
DEVELOPED OVER THE WEST IN THE EARLY MORNING ON 4/21 AS ANOTHER
DISTURBANCE DROPPING SOUTHEAST THROUGH THE UPPER TROUGH APPROACHED
THE AREA. TOTAL WATER EQUIVALENT PRECIPITATION ON 4/20 THROUGH
DAYBREAK ON 4/21 RANGED FROM 0.35 TO 0.75 INCH AT MOST PLACES.
IRONWOOD REPORTED THE MOST WITH 1.04 INCHES. MANY OF THE HIGHER
TERRAIN LOCATIONS OVER THE NORTHWEST REPORTED 2 TO 4 INCHES OF WET
SNOW DURING THIS TIME. AS MUCH AS 5 INCHES ACCUMULATED AT ATLANTIC
MINE AND REDRIDGE IN HOUGHTON COUNTY. MEAN DAILY TEMPERATURES
DROPPED FORM NEAR NORMAL ON 4/19 TO UP TO 5 DEGREES BELOW AVERAGE ON
4/20.

SCATTERED TO NUMEROUS SNOW SHOWERS CONTINUED ON 4/21 BUT BECAME
MIXED WITH RAIN IN THE AFTERNOON ESPECIALLY AT THE LOWER ELEVATIONS
IN THE PERSISTENT NORTHWEST FLOW OF MOIST AND CHILLY CANADIAN AIR
AROUND DEEP LOW PRESSURE JUST SOUTH OF JAMES BAY. DURING THE NIGHT
ON 4/21-4/22... NUMEROUS SNOW SHOWERS CONTINUED OVER MAINLY THE
HIGHER TERRAIN OF THE WEST AND NORTH CENTRAL AS NORTHWEST WIND GUSTS
REACHED 35 MPH. ADDITIONAL 24-HOUR SNOWFALL THROUGH DAYBREAK ON 4/22
WAS 1 TO 3 INCHES AT MOST PLACES OVER THE WEST AND NORTH CENTRAL...
BUT BESSEMER IN GOGEBIC COUNTY MEASURED AS MUCH AS 8.5 INCHES. LESS
THAN AN INCH OF SNOW WAS THE RULE OVER THE SOUTH CENTRAL AND EAST.
WATER EQUIVALENT PRECIPITATION RANGED FROM ABOUT 0.05 TO 0.35 INCH
AT MOST LOCATIONS. THE CORE OF THE COLD AIR MOVED OVERHEAD ON
4/22...AND MANY LOCATIONS REPORTED NEW DAILY RECORD LOW MAXIMUM
TEMPERATURES UNDER A GREY OVERCAST. AT THE COLDER SPOTS OVER THE
NORTH CENTRAL AND WEST...THE THERMOMETER READ NO HIGHER THAN 32.
READINGS AT NEGAUNEE IN MARQUETTE COUNTY TOPPED OUT AT A RECORD 26.
GUSTY NORTHWEST WINDS TO 30 MPH MADE THE DAY FEEL EVEN COLDER.
SEVERAL MORE INCHES OF WET SNOW ACCUMULATED...ONCE AGAIN MAINLY OVER
THE WEST AND NORTH CENTRAL. AS THE DEEP LOW NEAR JAMES BAY FINALLY
BEGAN TO MOVE NORTHEAST...THE GUSTY NORTHWEST WINDS AND SNOW SHOWERS
FINALLY BEGAN TO DIMINISH DURING THE NIGHT ON 4/22-4/23. ADDITIONAL
SNOWFALL THROUGH SUNRISE ON 4/23 WAS 1 TO 3 INCHES ACROSS THE WEST
AND NORTH CENTRAL WITH UP TO 4.2 INCHES AT IRONWOOD. ANY
ACCUMULATION FROM IRON MOUNTAIN TO ESCANABA...MANISTIQUE AND
NEWBERRY WAS UNDER AN INCH. DAILY AVERAGE TEMPERATURES WERE 5 TO 10
DEGREES BELOW NORMAL ON 4/21 AND A VERY CHILLY 15 TO 20 DEGREES
BELOW THE MEAN ON 4/22.

ANY LINGERING CLOUDS AND FLURRIES IN THE MORNING ON 4/23 GAVE WAY TO
A MOSTLY SUNNY AFTERNOON WITH THE CLOSER APPROACH OF HIGH PRESSURE
BUILDING EAST ACROSS THE PLAINS. MOSTLY CLEAR SKIES AND LIGHT WINDS
ASSOCIATED WITH THIS HIGH RESULTED IN SOME RECORD LOW MINIMUM
TEMPERATURES AS LOW AS 10 TO 15 AT SOME OF THE INTERIOR COLD SPOTS
AT DAWN ON 4/24. ANOTHER HIGH PRESSURE SYSTEM OVER CENTRAL CANADA
THEN BECAME THE DOMINANT INFLUENCE ON UPPER MICHIGAN WEATHER FOR
4/24 THROUGH 4/27...BRINGING A PERIOD OF CLEAR TO PARTLY CLOUDY
SKIES. MEAN DAILY TEMPERATURES WERE AROUND 10 DEGREES BELOW NORMAL
ON 4/23 THROUGH 4/25...THEN AROUND 5 DEGREES BELOW AVERAGE ON 4/26
AND 4/27.

AS THE HIGH PRESSURE RIDGE SHIFTED TO THE EAST ON 4/28...A SOUTHWEST
WIND ADVECTED WARMER AIR INTO THE UPPER GREAT LAKES...ALLOWING THE
MEAN DAILY TEMPERATURE TO REBOUND BACK TO NEAR NORMAL. A COLD FRONT
CROSSED THE AREA DURING THE NIGHT ON 4/28-4/29...BUT WAS ACCOMPANIED
ONLY BY SOME CLOUDS DUE TO THE DRYNESS OF THE AIRMASS IN PLACE.
ANOTHER SURGE OF COOLER CANADIAN AIR BEHIND THIS FRONT DROPPED MEAN
DAILY TEMPERATURES UP TO 5 DEGREES BELOW AVERAGE ON 4/29 AND 4/30.
THERE WAS A GOOD DEAL OF CLOUD COVER AT TIMES ESPECIALLY NEAR LAKE
SUPERIOR ON 4/30 WITH A STEADY NORTH WIND TO THE SOUTH OF HIGH
PRESSURE CROSSING FAR NORTHWEST ONTARIO...BUT NOTHING MORE THAN A
FEW SPRINKLES FELL ON THAT DAY.

                            MAY FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING AN EQUAL CHANCE
OF AN ABOVE AND BELOW NORMAL MONTHLY MEAN TEMPERATURE OVER THE
NORTHWEST HALF OF UPPER MICHIGAN BUT A GREATER THAN CLIMATOLOGICAL
CHANCE OF AN ABOVE NORMAL MONTHLY MEAN TEMPERATURE OVER THE
SOUTHEAST HALF IN MAY 2015. THE CPC EXPECTS A GREATER THAN
CLIMATOLOGICAL CHANCE OF BELOW NORMAL PRECIPITATION OVER ALL OF
UPPER MICHIGAN IN MAY.

                           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.
