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

AS IS NORMAL...GREAT LAKES WATER LEVELS ROSE IN MAY 2015. EXTENSIVE
ICE COVER ON LAKE SUPERIOR THIS PAST WINTER THAT HAS HELD DOWN WATER
TEMPERATURES AND LIMITED EVAPORATION AS WELL AS RUNOFF FROM SOME
PERIODS OF HEAVY RAIN IN MAY AIDED THESE WATER LEVEL RISES. AT THE
END OF MAY...WATER LEVELS ON LAKE SUPERIOR WERE 9 TO 10 INCHES ABOVE
NORMAL AND 4 TO 5 INCHES HIGHER THAN THE MAY AVERAGE IN 2014. THE
LEVEL ON LAKES MICHIGAN AND HURON WAS 6 TO 7 INCHES ABOVE AVERAGE ON
5/31 AND ALMOST 15 INCHES HIGHER THAN DURING MAY 2014.

SOME ICE COVER LINGERED OVER FAR EASTERN LAKE SUPERIOR NEAR THE
ONTARIO SHORELINE NORTH OF WHITEFISH POINT INTO MID MAY BUT MELTED
BY AROUND 5/20.

HIGHEST MONTHLY SNOWFALL...1.0 INCHES AT ATLANTIC MINE
                            IN HOUGHTON COUNTY

ALTHOUGH GENERALLY DRY WEATHER PREVAILED THROUGH MUCH OF MAY...THE
WEATHER PATTERN THE LAST WEEK OF THE MONTH TURNED MUCH WETTER AS AN
UPPER TROUGH FORMED OVER THE PLAINS. THE INTERACTION BETWEEN THE
MOIST SOUTHWEST FLOW AHEAD OF THIS FEATURE AND PASSING DISTURBANCES
RESULTED IN PERIODS OF MODERATE TO HEAVY SHOWERS AND THUNDERSTORMS
FROM 5/24 INTO 5/30. THE HEAVIEST RAINS DURING THIS WEEK FELL OVER
THE SOUTH CENTRAL. NORWAY IN DICKINSON COUNTY AND DAGGETT IN
MENOMINEE COUNTY WERE INUNDATED BY AS MUCH AS 6.50 AND 5.28 INCHES
OF RAIN RESPECTIVELY DURING THIS PERIOD. AT THE MARQUETTE NWS
OFFICE...DAILY RAINFALL BROKE THE RECORD PRECIPITATION ON THREE
STRAIGHT DAYS FROM 5/25 TO 5/27. SEVERAL RIVERS AND STREAMS REACHED
BANKFULL FOLLOWING THE RUNOFF FROM THESE DELUGES. TOTAL MAY
PRECIPITATION AT NORWAY AND DAGGETT TOPPED 7 INCHES...REACHING 7.69
INCHES OR ABOUT 250 PERCENT OF NORMAL AT NORWAY. IN GENERAL...MAY
RAINFALL WAS 4 INCHES OR MORE OVER MUCH OF THE CENTRAL UPPER
PENINSULA...WITH LESSER AMOUNTS MORE COMMON OVER THE WEST AND EAST.
A FEW LOCATIONS IN THESE AREAS MEASURED LESS THAN 3 INCHES OF RAIN
IN MAY...INCLUDING THE MONTHLY MINIMUM OF 2.33 INCHES THAT FELL AT
BARAGA. COPPER HARBOR PICKED UP 2.44 INCHES OF RAIN...ABOUT 85
PERCENT OF THE MONTHLY AVERAGE.

THE FIRST SEVERE THUNDERSTORM OF THE SEASON DROPPED QUARTER-SIZED
HAIL NEAR CHAMPION IN MARQUETTE COUNTY IN THE LATE AFTERNOON ON 5/3.
IN ADDITION TO DROPPING SOME TORRENTIAL DOWNPOURS...A FEW OF THE
THUNDERSTORMS TURNED SEVERE ON 5/27 AND 5/28. STEPHENSON IN
MENOMINEE COUNTY REPORTED QUARTER-SIZED HAIL IN THE EVENING ON 5/27.
ANOTHER STORM BOMBARDED NORWAY IN DICKINSON COUNTY WITH 2 INCH
DIAMETER HAIL DURING THE EVENING ON 5/28.

MONTHLY AVERAGE TEMPERATURES RANGING BETWEEN 48 AND 55 DEGREES WERE
11 TO 15 DEGREES HIGHER THAN THE MEAN TEMPERATURES REPORTED IN APRIL
AND GENERALLY WITHIN A DEGREE OF SO OF THE MAY NORMAL AT ALL
LOCATIONS BECAUSE THE TEMPERATURES ANOMALIES DURING THE RELATIVELY
COOL AND WARM PERIODS TENDED TO BALANCE OUT. THE WARMEST WEATHER
RELATIVE TO NORMAL PREVAILED AT TIMES DURING THE FIRST WEEK...WHEN
AN UPPER RIDGE DOMINATED THE EASTERN UNITED STATES. MANY LOCATIONS
AWAY FROM THE COOLING INFLUENCE OF LAKE MICHIGAN REPORTED THE FIRST
80-DEGREE OR HIGHER TEMPERATURES OF THE YEAR ON 5/3 OR 5/7. SOME OF
THE HIGHER TEMPERATURES WERE DAILY RECORD MAXIMUMS. THE MERCURY
AVERAGED ABOUT 20 DEGREES ABOVE THE MEAN ON 5/7...WHICH ENDED UP AS
THE WARMEST DAY OF THE ENTIRE MONTH AT MANY PLACES. IN ADDITION TO
5/3 AND 5/7...READINGS PEAKED AT 80 OR ABOVE AT AT LEAST A FEW SPOTS
ON 5/23...5/24...5/27 AND 5/28.

AN UPPER TROUGH ACROSS EASTERN NORTH AMERICA AND MUCH COOLER WEATHER
WERE THE RULE DURING PORTIONS OF THE SECOND AND THIRD WEEKS AS WELL
AS AT THE END OF MAY. MEAN DAILY TEMPERATURES RAN AS MUCH AS 15 TO
20 DEGREES BELOW AVERAGE DURING THE COOLEST DAYS ON 5/19 AND 5/31.
SOME SNOW FELL AND WHITENED THE GROUND AT MANY PLACES ON 5/19...BUT
ANY ACCUMULATION WAS UNDER AN INCH. THE THERMOMETER PEAKED AT ONLY
38 DEGREES AT GRAND MARAIS IN ALGER COUNTY ON 5/19. DURING THE
FOLLOWING NIGHT...READINGS DIPPED INTO THE UPPER TEENS AT SOME OF
THE INTERIOR COLD SPOTS BY SUNRISE ON 5/20. MINIMUM TEMPERATURES
FELL INTO THE 20S AT SOME OF THE INTERIOR COLD SPOTS ON 5/1...5/5...
5/10...5/13...5/19 THROUGH 5/23 AND ON 5/31. SOME NEW DAILY RECORD
LOW MAXIMUM TEMPERATURES IN THE 40S WERE REPORTED NEAR LAKE SUPERIOR
ON 5/31 AS CANADIAN HIGH PRESSURE BUILT INTO THE UPPER GREAT LAKES.

                         MAY WEATHER SUMMARY

A LARGE AREA OF HIGH PRESSURE THAT MOVED SLOWLY FROM THE GREAT LAKES
INTO THE SOUTHEAST STATES BROUGHT DRY WEATHER TO UPPER MICHIGAN ON
5/1 AND 5/2. THE SOUTHWEST FLOW AROUND THIS HIGH ADVECTED WARMER AIR
INTO UPPER MICHIGAN...ALLOWING MEAN DAILY TEMPERATURES TO RISE FROM
NEAR NORMAL TO 5 DEGREES ABOVE AVERAGE ON 5/1 TO 10 TO 15 DEGREES
ABOVE NORMAL ON 5/2. LOCATIONS NEAR THE CHILLY GREAT LAKES WERE
COOLEST. MAXIMUM TEMPERATURES ROSE INTO THE 80S AT SOME LOCATIONS ON
5/3 UNDER THE STRENGTHENING SOUTHWEST FLOW BETWEEN THE HIGH MOVING
OFF THE SOUTHEAST COAST AND AN APPROACHING COLD FRONT...RAISING THE
MEAN DAILY TEMPERATURE TO 10 TO 20 DEGREES ABOVE AVERAGE. NORWAY AND
RANDVILLE IN DICKINSON COUNTY AND PELKIE IN BARAGA COUNTY WERE
WARMEST WITH A MAXIMUM OF 83. AS THE COLD FRONT MOVED CLOSER AND
LIFTED THIS WARM AIRMASS...SOME SHOWERS AND THUNDERSTORMS DEVELOPED
OVER THE WEST CENTRAL LATER IN THE AFTERNOON AND THEN MOVED EAST
DURING THE EVENING. THE SHOWERS AND STORMS WERE LEAST NUMEROUS OVER
THE FAR WEST AND KEWEENAW. AWAY FROM THIS AREA...MANY OF THE
STRONGER STORMS DROPPED SMALL HAIL AND HEAVY RAIN INTO THE EVENING
ON 5/3. THE STRONGEST STORM BOMBARDED A LOCATION NEAR CHAMPION IN
MARQUETTE COUNTY WITH QUARTER-SIZED HAIL. THE HEAVIEST RAINS
OCCURRED OVER THE SOUTHEAST UPPER PENINSULA...WHERE GARDEN CORNERS
IN DELTA COUNTY REPORTED 2.04 INCHES OF RAIN ON 5/3. SOME OTHER
IMPRESSIVE RAINFALL INCLUDED 1.46 INCHES AT GLADSTONE IN DELTA
COUNTY AND 1.14 INCHES AT COOKS IN SCHOOLCRAFT COUNTY.

BEHIND THE COLD FRONTAL PASSAGE...CANADIAN HIGH PRESSURE MOVED
THROUGH MINNESOTA AND INTO THE GREAT LAKES ON 5/4. THE STEADY NORTH
WIND AHEAD OF THIS HIGH DROPPED THE MEAN DAILY TEMPERATURE ON 5/4 TO
WITHIN A FEW DEGREES OF THE DAILY AVERAGE. THE MERCURY DIPPED INTO
THE 20S AT MANY OF THE INTERIOR COLD SPOTS DURING THE NIGHT ON 5/4-
5/5. BUT THE SOUTH WIND ON THE WESTERN FLANK OF THE DEPARTING HIGH
DREW MUCH WARMER AIR BACK INTO THE UPPER LAKES SO THAT THE MEAN
DAILY TEMPERATURE ON 5/5 RECOVERED TO AROUND 5 DEGREES ABOVE NORMAL
AWAY FROM THE COOLING INFLUENCE OF LAKE MICHIGAN.

AS THE HIGH PRESSURE SYSTEM CONTINUED TO THE EAST ON 5/6...CLOUDS
AND A FEW SHOWERS IN ADVANCE OF AN APPROACHING WARM FRONT OVERSPREAD
THE UPPER GREAT LAKES. FOLLOWING THE PASSAGE OF THE WARM FRONT...5/7
TURNED OUT TO BE A PARTLY TO MOSTLY SUNNY AND VERY WARM DAY THAT
FEATURED SOME DAILY RECORD MAXIMUM TEMPERATURES. THE MERCURY TOPPED
OUT WELL INTO THE 80S AT MANY LOCATIONS AWAY FROM THE COOLING
INFLUENCE OF LAKE MICHIGAN AND AS HIGH AS 87 AT PELKIE IN BARAGA
COUNTY. READINGS NEAR LAKE MICHIGAN WERE GENERALLY ONLY IN THE 60S.
SOUTHWEST WINDS GUSTING AS HIGH AS 35 TO 40 MPH TOOK A BIT OF THE
EDGE OFF THE SUMMER-LIKE HEAT. MEAN DAILY TEMPERATURES FROM 5 TO 10
DEGREES ABOVE NORMAL ON 5/6 ROSE TO 10 TO 20 DEGREES ABOVE AVERAGE
ON 5/7.

A COLD FRONT MOVING SLOWLY TOWARD THE WESTERN GREAT LAKES BROUGHT A
RETURN OF SOME SHOWERS OVER THE WEST DURING THE EARLY MORNING HOURS
OF 5/8. PLENTY OF CLOUDS ALONG WITH SCATTERED SHOWERS AND A FEW
THUNDERSTORMS THEN ACCOMPANIED THE PASSAGE OF THE COLD FRONT ON 5/8.
MOST PLACES SAW NO MORE THAN 0.05 TO 0.25 INCH OF RAIN...BUT
WATERSMEET IN GOGEBIC COUNTY SAW AS MUCH AS 0.65 INCH. NORTHWEST
WIND GUSTS AS HIGH AS 40 MPH OVER THE KEWEENAW BEHIND THE FRONTAL
PASSAGE ON 5/8 THEN DROVE MUCH COOLER AIR INTO THE AREA. MEAN DAILY
TEMPERATURES ON 5/8 RANGED FROM NEAR NORMAL OVER THE WEST TO AS MUCH
AS 10 DEGREES ABOVE AVERAGE FARTHER TO THE EAST DUE TO THE LATER
ARRIVAL OF THE FRONT. THERE WERE SOME LINGERING CLOUDS AND EVEN SOME
PATCHY DRIZZLE OVER MAINLY THE HIGHER TERRAIN NEAR LAKE SUPERIOR IN
THE MORNING OF 5/9...BUT HIGH PRESSURE BUILDING INTO ONTARIO BROUGHT
A RETURN OF MORE SUNSHINE IN THE AFTERNOON. ALTHOUGH SOME CLOUDS
ASSOCIATED WITH THE NORTHEAST FLOW OFF LAKE SUPERIOR TO THE SOUTH OF
THE ONTARIO HIGH LINGERED INTO 5/10...THERE WAS NO PRECIPITATION ON
THAT DAY. THE THERMOMETER AVERAGED 5 TO 10 DEGREES BELOW NORMAL ON
5/9 AND 5/10.

CLOUDS THICKENED AND SOME SHOWERS DEVELOPED DURING THE NIGHT ON 5/10-
5/11 AHEAD OF A LOW PRESSURE SYSTEM MOVING NORTHEAST FROM THE PLAINS
TOWARD THE WESTERN GREAT LAKES. AFTER THE LOW MOVED INTO ONTARIO
LATER ON 5/11...THE SHOWERS ENDED WEST TO EAST. BUT MORE SHOWERS
REDEVELOPED OVER MAINLY THE WEST DURING THE EARLY MORNING ON 5/12
AHEAD OF A TRAILING UPPER DISTURBANCE AND THEN SPREAD ACROSS THE
NORTHERN TIER. AS COLDER AIR RETURNED BEHIND THE EXITING SURFACE LOW
PRESSURE SYSTEM ON THE HEELS OF NORTHWEST WINDS GUSTING AS HIGH AS
35 TO 40 MPH ON 5/12...THE PRECIPITATION MIXED WITH SOME WET SNOW
OVER THE HIGHER TERRAIN OF THE WEST AND THEN OVER THE NORTH CENTRAL
AS WELL. PRECIPITATION TOTALS ON 5/11 THROUGH 5/12 WERE AT LEAST
0.25 TO 0.50 INCH AT MOST PLACES BUT REACHED AN INCH OR MORE AT A
FEW SPOTS. AS MUCH AS 1.14 INCHES FELL AT GARDEN CORNERS. MOHAWK IN
KEWEENAW COUNTY AND JACOBSVILLE IN HOUGHTON COUNTY BOTH LOGGED 1.02
INCHES. UP TO 0.5 INCH OF SNOW ACCUMULATED ON GRASSY SURFACES AT
ATLANTIC MINE IN HOUGHTON COUNTY. MEAN DAILY TEMPERATURES ABOUT 5
DEGREES BELOW NORMAL ON 5/11 DROPPED TO AROUND 10 DEGREES BELOW WITH
THE ARRIVAL OF THE COLDER AIR ON 5/12.

AS TRAILING HIGH PRESSURE BUILT INTO THE UPPER LAKES DURING THE
NIGHT ON 5/12-5/13...SKIES CLEARED...ALLOWING THE MERCURY TO PLUMMET
INTO THE 20S OVER THE INTERIOR WEST AND ALL THE WAY TO 25 AT
WAKEFIELD IN GOGEBIC COUNTY. ALTHOUGH SOME HIGH CLOUDS OVERSPREAD
THE U.P. THROUGH 5/14 WELL AHEAD OF A LOW PRESSURE SYSTEM IN THE
PLAINS...THE HIGH BROUGHT DRY WEATHER. MEAN DAILY TEMPERATURES
BETWEEN 5 AND 10 DEGREES BELOW AVERAGE ON 5/13 REBOUNDED TO NEAR
NORMAL ON 5/14. THE PLAINS LOW PRESSURE SYSTEM MOVED NORTHEAST
TOWARD UPPER MICHIGAN...CAUSING SOME THICKENING CLOUDS AND RAIN
SHOWERS TO OVERSPREAD THE AREA DURING THE NIGHT ON 5/14-5/15.
LINGERING SHOWERS DIMINISHED BY THE AFTERNOON ON 5/15 AS THE LOW
PRESSURE CENTER SHIFTED TO THE EAST AND WEAK HIGH PRESSURE BUILT
TOWARD THE AREA. MOST PLACES MEASURED 0.10 TO 0.25 INCH OF RAIN
DURING THIS EVENT. MEAN DAILY TEMPERATURES ON 5/15 WERE NEAR NORMAL
TO 5 DEGREES BELOW AVERAGE.

A STEADY SOUTH WIND BETWEEN THE HIGH PRESSURE RIDGE EDGING TO THE
EAST AND LOW PRESSURE LIFTING NORTHEAST THROUGH THE PLAINS ADVECTED
WARMER AIR INTO THE UPPER LAKES ON 5/16. THE ARRIVAL OF MORE HUMID
AIR ON 5/17 BROUGHT MORE CLOUDS ALONG WITH SOME SHOWERS AND
THUNDERSTORMS. THERE WAS ALSO SOME PATCHY FOG...ESPECIALLY DOWNWIND
OF LAKE MICHIGAN. LINGERING SHOWERS AND THUNDERSTORMS MAINLY OVER
THE WEST IN THE EVENING ON 5/17 ENDED WITH THE PASSAGE OF THE COLD
FRONT BY DAYBREAK ON 5/18 THAT FOLLOWED THE SURFACE LOW PRESSURE
TRACKING INTO ONTARIO. RAINFALL WAS GENERALLY 0.05 TO 0.15 INCH.
SOME HIGHER AMOUNTS FELL UNDER THE HEAVIER SHOWERS...INCLUDING 0.85
INCH AT TAHQUAMENON FALLS IN LUCE COUNTY AND 0.50 INCH AT CRYSTAL
FALLS. SKIES TURNED MOSTLY SUNNY FOR AWHILE ON 5/18 BEHIND THE
DEPARTING FRONT...BUT THE APPROACH OF A SECOND COLD FRONT ASSOCIATED
WITH A DEEPENING UPPER TROUGH BROUGHT A RETURN OF MORE CLOUDS AND
EVEN SOME SCATTERED SHOWERS...ESPECIALLY OVER THE WEST HALF.
UNSEASONABLY CHILLY CANADIAN AIR FOLLOWED THE REINFORCING COLD
FRONTAL PASSAGE...SO THE RAIN SHOWERS MIXED WITH SOME SNOW OVER THE
HIGHER TERRAIN NEAR LAKE SUPERIOR DURING THE EARLY MORNINGS HOURS ON
5/19. BY THE TIME THE RAIN AND SNOW SHOWERS DIMINISHED IN THE
AFTERNOON ON 5/19 WITH THE CLOSER APPROACH OF HIGH PRESSURE IN THE
NORTHERN PLAINS...SOME HIGHER TERRAIN LOCATIONS ACROSS THE WEST HAD
PICKED UP AROUND 0.25 INCH OF WATER EQUIVALENT PRECIPITATION A FEW
TENTHS OF AN INCH OF WET SNOW. THE MERCURY AVERAGED 5 TO 10 DEGREES
ABOVE NORMAL ON 5/16 AND 5/17. READINGS FELL TO AROUND 5 DEGREES
BELOW NORMAL ON 5/18 AND THEN 15 DEGREES BELOW THE MEAN ON 5/19 WITH
THE ARRIVAL OF THE COLDER CANADIAN AIR.

SKIES CLEARED DURING THE NIGHT ON 5/19-5/20 AS THE CANADIAN HIGH
MOVED OVER UPPER MICHIGAN. WITH LIGHT WINDS...TEMPERATURES TUMBLED
INTO THE 20S AT MANY OF THE INTERIOR COLD SPOTS AND AS LOW AS THE
MONTHLY MINIMUM OF 18 NEAR NEWBERRY AND JUST INLAND FROM MUNISING.
DRY HIGH PRESSURE UNDER A SLOWLY BUILDING UPPER RIDGE THEN DOMINATED
THE WEATHER ON 5/20 THROUGH 5/23. ALTHOUGH A WEAK COLD FRONT SWUNG
ACROSS THE UPPER LAKES ON 5/21...THE AIRMASS WAS TOO DRY FOR
ANYTHING MORE THAN SOME CLOUDS. MEAN DAILY TEMPERATURES RAN 5 TO 10
DEGREES BELOW AVERAGE ON 5/20 THROUGH 5/22. THE MORNING ON 5/22 WAS
ANOTHER CHILLY ONE WITH THE HIGH CENTER TRAILING THE SECOND COLD
FRONTAL PASSAGE MOVING OVERHEAD. THE THERMOMETER READ AS LOW AS THE
20S AT MANY INTERIOR LOCATIONS AT DAWN ON 5/22...INCLUDING 22 AT THE
LOCATION JUST INLAND FROM MUNISING. READINGS THEN REBOUNDED TO 5 TO
10 DEGREES ABOVE NORMAL ON 5/23 AFTER THE HIGH PRESSURE CENTER
SHIFTED TO THE SOUTHEAST AND A WEST TO SOUTHWEST FLOW AROUND THIS
FEATURE DREW WARMER AIR INTO THE UPPER LAKES.

AS THE UPPER RIDGE MIGRATED INTO THE EASTERN UNITED STATES ON
5/24...THE FLOW ALOFT OVER THE CENTRAL BECOME MORE SOUTHWEST...
SETTING THE STAGE FOR A VERY WET WEEK OF WEATHER OVER UPPER
MICHIGAN. THE FIRST LOW PRESSURE SYSTEM CARRIED TO THE NORTHEAST IN
THIS MOIST FLOW ALOFT BROUGHT THICKENING CLOUDS TO THE AREA ON 5/24.
SOME RAIN ARRIVED NEAR THE WISCONSIN BORDER LATE IN THE DAY AND
MOVED ACROSS THE REST OF THE U.P. DURING THE EVENING. THIS RAIN
CONTINUED MODERATE TO HEAVY AT TIMES INTO 5/25. BY THE TIME THE RAIN
DIMINISHED TO SCATTERED SHOWERS ON MEMORIAL DAY AFTERNOON...MOST
PLACES AWAY FROM SOUTHEAST UPPER MICHIGAN HAD BEEN SOAKED BY AN INCH
OR MORE OF PRECIPITATION...SETTING SOME NEW DAILY RAINFALL RECORDS.
ARNOLD IN MARQUETTE COUNTY AND IRON MOUNTAIN LED REPORTING STATIONS
WITH 2.40 AND 2.08 INCHES OF RAIN RESPECTIVELY. GARDEN CORNERS SAW
THE LEAST WITH 0.66 INCH. AREAS OF DENSE FOG DEVELOPED LATE ON 5/25
AND PERSISTED THROUGH SUNRISE ON 5/26. THE FOG WAS THICKEST NEAR
LAKE MICHIGAN. MEAN DAILY TEMPERATURES ON 5/24 AND 5/25 AVERAGED 5
TO 10 DEGREES ABOVE NORMAL.

AFTER A BREAK IN THE WIDESPREAD RAIN FROM LATE ON 5/25 INTO 5/26...
ANOTHER PERIOD OF MODERATE RAIN AHEAD OF A LOW PRESSURE SYSTEM
MOVING NORTHEAST ALONG A STATIONARY FRONT SITUATED OVER THE UPPER
MIDWEST AND WESTERN GREAT LAKES OVERSPREAD THE U.P. THIS PERIOD OF
MODERATE TO HEAVY RAIN CONTINUED UNTIL THE LOW MOVED INTO ONTARIO ON
5/27...WHEN THE SHOWERS BECAME SCATTERED AND LIGHTER. DURING THIS
EVENT...THE HEAVIEST RAIN IN EXCESS OF AN INCH FELL ACROSS CENTRAL
UPPER MICHIGAN. TWO INCHES OF MORE FELL IN A CORRIDOR FROM CRYSTAL
FALLS AND IRON MOUNTAIN TO NEAR GWINN IN MARQUETTE COUNTY. FOLLOWING
SO QUICKLY AFTER THE HEAVY RAIN ON 5/24 INTO 5/25...RUNOFF FROM THIS
HEAVY PRECIPITATION CAUSED SOME RIVERS TO RISE TO NEAR BANKFULL.
AWAY FROM THE CENTRAL COUNTIES...RAINFALL TOTALS WERE GENERALLY 0.25
TO 0.75 INCH. SINCE THE SUN CAME OUT DURING THE AFTERNOON ON 5/27
AFTER THE LOW HAD DEPARTED TO THE NORTHEAST...A FEW THUNDERSTORMS
DEVELOPED WITH THE RESULTING INSTABILITY. ONE OF THE STORMS IN
MENOMINEE COUNTY BECAME SEVERE DURING THE EVENING ON 5/27 AND
DROPPED QUARTER-SIZED HAIL NEAR STEPHENSON. MEAN DAILY TEMPERATURES
ON 5/26 AND 5/27 REMAINED ABOUT 5 TO 10 DEGREES ABOVE NORMAL.

HIGH PRESSURE CROSSING ONTARIO BROUGHT A PERIOD OF DRY WEATHER
DURING THE MORNING ON 5/28...BUT MORE SHOWERS AND THUNDERSTORMS
MOVED INTO THE AREA LATER IN THE DAY AHEAD OF THE NEXT DISTURBANCE
EMBEDDED IN THE MOIST SOUTHWEST FLOW. SOME OF THE STORMS OVER
DICKINSON COUNTY TURNED SEVERE IN THE LATE AFTERNOON AND EARLY
EVENING ON 5/28...BOMBARDING NORWAY IN DICKINSON COUNTY WITH HAIL UP
TO 2 INCHES IN DIAMETER. A LOCATION NEAR NORWAY ALSO REPORTED 2.60
INCHES OF RAIN DURING THIS THUNDERSTORM. MORE WIDESPREAD SHOWERS AND
A FEW THUNDERSTORMS THEN ENVELOPED THE U.P. ON 5/29 AHEAD OF A COLD
FRONT APPROACHING THROUGH MINNESOTA. THE MOIST SOUTHERLY FLOW AHEAD
OF THIS FRONT BROUGHT A RETURN OF MORE DENSE FOG...ESPECIALLY
DOWNWIND OF LAKE MICHIGAN. THE RAIN AND FOG FINALLY DIMINISHED
DURING THE NIGHT ON 5/29-5/30 AS THE COLD FRONT PASSED AND COOLER
AND DRIER AIR AHEAD OF CANADIAN HIGH PRESSURE PUSHED INTO THE UPPER
LAKES. AWAY FROM THE DELUGE IN DICKINSON COUNTY...MOST PLACES
MEASURED 0.25 TO 0.75 INCH OF RAIN FROM LATE ON 5/28 INTO 5/30. THE
MONTH THEN ENDED ON A COOL DRY NOTE AS THE CANADIAN HIGH PRESSURE
SYSTEM DRIFTED NEAR LAKE SUPERIOR ON 5/31. MORNING LOW TEMPERATURES
DIPPED INTO THE 20S AT SOME OF THE COLD SPOTS OVER THE INTERIOR WEST
ON 5/31. THE STEADY NORTH WIND OFF THE CHILLY WATERS OF LAKE
SUPERIOR HELD THE MERCURY IN THE 40S OVER THE HIGHER TERRAIN OF THE
NORTHERN TIER ON 5/31. SOME OF THE LOWER READINGS ESTABLISHED NEW
DAILY RECORD LOW MAXIMUMS AT A FEW SPOTS. MEAN DAILY TEMPERATURES
ON 5/28 AND 5/29 HELD AT 5 TO 10 DEGREES ABOVE NORMAL. THE
THERMOMETER AVERAGED 10 TO 15 DEGREES BELOW NORMAL ON 5/30 AND 5/31.

                            JULY FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING AN EQUAL CHANCE
OF AN ABOVE AND BELOW NORMAL MONTHLY AVERAGE TEMPERATURE AND ABOVE
AND BELOW NORMAL MONTHLY PRECIPITATION OVER ALL OF UPPER MICHIGAN IN
JULY 2015.

                           JULY CLIMATOLOGY

ALTHOUGH DAYLIGHT BEGINS TO GROW SHORTER DURING JULY (946 MINUTES OF
POSSIBLE SUNSHINE ON 7/1 DECREASES TO 894 MINUTES ON 7/31) AS THE
SUN STARTS ITS ANNUAL MIGRATION SOUTHWARD...AVERAGE MONTHLY
TEMPERATURES PEAK DURING THE SEVENTH MONTH...ABOUT 5 DEGREES HIGHER
THAN IN JUNE. TEMPERATURES OVER 100 ARE RARE IN UPPER MICHIGAN...BUT
THEY ARE MOST LIKELY IN JULY. THE MOST EXTREME HEATWAVE IN UPPER
MICHIGAN HISTORY OCCURRED DURING THE SECOND WEEK OF JULY 1936.
RESIDENTS OF NEWBERRY ENDURED SIX DAYS IN A ROW FROM 7/8/36 TO
7/13/36 WHERE THE HIGH TEMPERATURE REACHED 100 OR ABOVE...INCLUDING
AN ALL TIME RECORD 103 DEGREE READING ON 7/13/36. IN FACT...THE
SEVEN HOTTEST DAYS IN NEWBERRY HISTORY OCCURRED DURING THE WEEK OF
7/8/36 TO 7/14/36. IRONWOOD AND IRON MOUNTAIN ALSO RECORDED THEIR
ALL TIME HIGHEST TEMPERATURE ON 7/13/36 WITH MAXIMUM TEMPERATURES OF
104 AND 103 RESPECTIVELY. EVEN THOUGH THE 104 READING IN DOWNTOWN
MARQUETTE ON 7/13/36 IS NOT THE HIGHEST TEMPERATURE EVER OBSERVED
THERE...WHICH IS 108 ON 7/15/1901...THAT FACT PROBABLY WAS OF LITTLE
COMFORT TO LOCAL RESIDENTS...WHO ALSO SUFFERED THROUGH SWELTERING
LOW TEMPERATURES OF 80 ON 7/8/36 AND 7/9/36.

IN RECENT MEMORY...JULY IN 2006 AND 2011 WERE QUITE WARM OVER UPPER
MICHIGAN WITH MONTHLY MEAN TEMPERATURES AVERAGING 2 TO 5 DEGREES
ABOVE THE 30-YEAR NORMAL. THOUSAND ISLAND LAKE IN GOGEBIC COUNTY
REPORTED A MAXIMUM TEMPERATURE OF 100 OR BETTER ON FOUR DAYS IN JULY
2006...WHICH GOES DOWN IN THE RECORD BOOKS AS ONE OF THE TOP 10
WARMEST SEVENTH MONTHS AT ALL REPORTING SITES. JULY 2011 WAS ALSO
ONE OF THE TOP 10 WARMEST AT MANY LOCATIONS.

AT THE OTHER EXTREME...COOL AIRMASSES FROM CANADA CAN BRING FROST TO
MAINLY OUTLYING AREAS OF UPPER MICHIGAN DURING JULY. IRONWOOD
RECORDED A 31 DEGREE READING ON 7/2/1907...AND NEWBERRY OBSERVED 32
ON 7/21/92. ON 7/19 AND 7/20/2000...FROST DEVELOPED AT SOME INTERIOR
LOCATIONS AS CANADIAN HIGH PRESSURE PARKED ITSELF OVERHEAD AND
DROPPED THE MERCURY AS LOW AS 28. JULY 1992 GOES DOWN IN THE RECORD
BOOKS AT MOST UPPER MICHIGAN STATIONS AS THE COOLEST EVER. MEAN JULY
1992 TEMPERATURES THROUGHOUT THE AREA AVERAGED SIX TO NINE DEGREES
BELOW THE NORMAL OF 65 TO 68. JULY 2009 ENDED UP AS THE SECOND
COOLEST SEVENTH MONTH ON RECORD AT MOST PLACES...TRAILING ONLY JULY
1992 WITH A MEAN MONTHLY TEMPERATURE 4 TO 6 DEGREES BELOW AVERAGE.
JULY 2004 WAS ALSO QUITE CHILLY...WITH MOST LOCATIONS OBSERVING
MONTHLY AVERAGE TEMPERATURES 2 TO 5 DEGREES BELOW NORMAL.

ALTHOUGH THE AVERAGE JULY TENDS TO BE DRIER THAN JUNE BECAUSE THE
JET STREAM AND MOST WEATHER DISTURBANCES ARE FARTHER NORTH...
FREQUENT JULY THUNDERSTORMS CAN DROP HEAVY RAINS. DURING THE
OVERNIGHT OF 7/14-7/15 IN 1999...THUNDERSTORMS DELUGED SOUTHERN IRON
COUNTY WITH AS MUCH AS 8 INCHES OF RAIN AND CAUSED SOME FLASH
FLOODING. IN JULY 1909...AS MUCH AS 15.45 INCHES OF RAIN INUNDATED
IRONWOOD. MOST OF THIS RAIN FELL ON 7/19 INTO 7/22...WHEN THAT SITE
REPORTED AN INCREDIBLE 13.21 INCHES DURING THAT FOUR DAY STRETCH.

             OUTLOOK FOR LATE SUMMER AND EARLY FALL
