LOWEST MONTHLY PRECIPITATION...1.91 INCHES AT COOKS IN SCHOOLCRAFT
                                COUNTY

OVERALL...JUNE 2013 ENDED UP WETTER AND COOLER THAN NORMAL AT MOST
PLACES...THE FIFTH MONTH IN A ROW A PERSISTENT UPPER TROUGH IN
EASTERN CANADA AND A NW FLOW ALOFT OVER THE GREAT LAKES DOMINATED
THE WEATHER PATTERN. MEAN DAILY TEMPERATURES RANGING FROM 54 TO 63
DEGREES ACROSS UPPER MICHIGAN IN JUNE RAN FROM NEAR NORMAL TO AS
MUCH AS 2 DEGREES BELOW AVERAGE. THE JUNE MEAN DAILY TEMPERATURE WAS
8 TO 12 DEGREES WARMER THAN THE MAY AVERAGE.

AS HAS BEEN THE CASE IN RECENT MONTHS...THE HEAVIEST PRECIPITATION
FELL OVER WESTERN UPPER MICHIGAN IN JUNE. MANY LOCATIONS FROM
IRONWOOD THROUGH THE KEWEENAW LOGGED 5 TO 6 INCHES OR MORE OF RAIN
DURING JUNE...AS MUCH AS 150 TO 175 PERCENT OF THE MONTHLY NORMAL.
THIS HEAVY JUNE RAINFALL LIFTED PRECIPITATION AMOUNTS FOR THE FIRST
HALF OF 2013 TO NEAR RECORD AMOUNTS AT SOME LOCATIONS. AT
IRONWOOD...THE 25.28 INCHES THAT FELL FROM 1/1 THROUGH 6/30 THIS
YEAR IS SECOND ONLY TO THE 25.41 INCHES MEASURED IN JANUARY THROUGH
JUNE IN 1939 FOR THE HIGHEST FIRST SIX MONTH PRECIPITATION SINCE
1901. OVER THE EAST...WHERE PRECIPITATION THE FIRST HALF OF 2013 HAS
BEEN CLOSER TO NORMAL...JUNE RAINFALL WAS A MORE MODEST 2 TO 3
INCHES...AS LITTLE AS 75 PERCENT OF NORMAL AT MANISTIQUE.

THE BULK OF THE JUNE RAIN FELL DURING THE FIRST AND FOURTH WEEKS OF
THE MONTH. A STRONG COLD FRONT PASSING THROUGH THE GREAT LAKES
DURING THE OVERNIGHT OF 6/1-6/2 CAUSED NUMEROUS SHOWERS AND A FEW
THUNDERSTORMS. AN INCH OR MORE OF RAIN FELL AT SEVERAL LOCATIONS
OVER THE CENTRAL AND EAST...WITH UP TO 1.34 INCHES AT IRON MOUNTAIN.
AN APPROACHING WARM FRONT CAUSED SOME LOCALLY HEAVIER RAINS ON 6/5
AND 6/6 OVER THE FAR WEST...WHERE AS MUCH AS 1.16 INCHES AND 1.14
INCHES FELL AT IRONWOOD AND WATERSMEET IN GOGEBIC COUNTY
RESPECTIVELY. DURING ONE PARTICULARLY WET PERIOD ON 6/20 THROUGH
6/22 WHEN A STATIONARY FRONT WAS DRAPED ACROSS UPPER MICHIGAN...2
INCHES OR MORE OF RAIN INUNDATED A NUMBER OF WESTERN LOCATIONS. SOME
OF THE MORE NOTABLE RAINFALL REPORTS DURING THIS TIME INCLUDED 2.57
INCHES AT BARAGA...2.46 INCHES AT IRONWOOD...AND 2.36 INCHES AT
HOUGHTON. A SERIES OF STRONG UPPER DISTURBANCE CROSSING THE GREAT
LAKES CAUSED MORE HEAVY SHOWERS AND THUNDERSTORMS ON 6/26 INTO 6/28.
AS MUCH AS 2.59 INCHES AND 2.51 INCHES OF RAIN DELUGED IRON MOUNTAIN
AND STAMBAUGH IN IRON COUNTY RESPECTIVELY DURING THIS PERIOD. SOME
OF THE THUNDERSTORMS LATE IN THE AFTERNOON AND EVENING ON 6/26
TURNED SEVERE WITH DAMAGING WINDS OVER THE NORTHERN TIER OF UPPER
MICHIGAN. HOUGHTON CLOCKED A WIND GUST AS HIGH AS 56 MPH UNDER ONE
OF THE STRONGER STORMS. ANOTHER SEVERE STORM STRUCK MARQUETTE COUNTY
IN THE EVENING ON 6/27...BOMBARDING A SITE NEAR CHAMPION WITH
QUARTER-SIZED HAIL.

THE ONLY PERIOD OF GENUINE SUMMER WARMTH TO INFLUENCE UPPER MICHIGAN
OCCURRED FROM 6/23 INTO 6/27...WHEN AN UPPER RIDGE BUILT INTO THE
GREAT LAKES AND TEMPORARILY DISLODGED THE PERSISTENT COOL NORTHWEST
FLOW. MEAN DAILY TEMPERATURES AVERAGED AROUND 10 DEGREES ABOVE NORMAL
DURING THIS TIME...AND THE ONLY 90-DEGREE TEMPERATURES OBSERVED OVER
THE U.P. IN JUNE OCCURRED ON 6/25. PELKIE IN BARAGA COUNTY REPORTED
THE HIGHEST MAXIMUM OF 91 ON THAT DATE. ON THE OTHER HAND...COOL
AIRMASSES INVADED THE UPPER GREAT LAKES ON SEVERAL OCCASIONS IN
JUNE. THE COOLEST PERIODS WERE 6/2 THROUGH 6/6 AND ON 6/17 INTO
6/19. THE MERCURY RAN ABOUT 10 DEGREES BELOW NORMAL DURING THESE
PERIODS...AND AT LEAST A FEW OF THE INTERIOR COLD SPOTS REPORTED A
MINIMUM TEMPERATURE IN THE 20S ON 6/3...6/4...6/18 AND 6/19.

CANADIAN AIRMASS OVER THE AREA. THIS AIRMASS LINGERED THE REST OF
THE FIRST WEEK OF JUNE...AND MEAN DAILY TEMPERATURES ON 6/2 THROUGH
6/6 ENDED UP AROUND 10 DEGREES BELOW NORMAL. THE OVERNIGHTS ON
6/2-6/3 AND 6/3-6/4 WERE PARTICULARLY CHILLY AS THE COMBINATION OF
MOSTLY CLEAR SKIES AND LIGHT WINDS UNDER THE INCOMING CANADIAN HIGH
PRESSURE SYSTEM ALLOWED THE MERCURY TO TUMBLE INTO THE 30S AT MANY
PLACES OVER THE INTERIOR AND AS LOW AS THE 20S AT THE COLDEST SPOTS.
THE THERMOMETER READ AS LOW AS 23 AT ONE NOTORIOUSLY CHILLY LOCATION
INLAND FROM MUNISING AT DAYBREAK ON 6/4. THERE WAS WIDESPREAD FROST
OVER THE INTERIOR ON THESE CHILLY MORNINGS.

CLOUDS TO THE NORTH OF A WARM FRONT IN THE UPPER MIDWEST BEGAN TO
THICKEN ON ON 6/4...AND SOME SHOWERS ARRIVED ON 6/5 AS THE FRONT
EDGED ONLY SLOWLY TO THE NORTH. ALTHOUGH SOME OF THESE SHOWERS
DRIFTED INTO THE EAST AS WELL...THE HEAVIER SHOWERS THAT LINGERED
THROUGH MUCH OF 6/6 WERE CONFINED TO MAINLY THE FAR WEST BECAUSE
HIGH PRESSURE NEAR HUDSON BAY MAINTAINED DRIER AIR OVER THE NORTH
CENTRAL AND ESPECIALLY THE EAST. IRONWOOD AND WATERSMEET IN GOGEBIC
COUNTY SAW THE MOST RAIN DURING THIS PERIOD...WITH TOTALS REACHING
1.16 INCHES AND 1.14 INCHES RESPECTIVELY. BUT PRECIPITATION AMOUNTS
FELL OFF STEADILY TO THE EAST...WITH LESS THAN 0.10 INCH FALLING ON
6/5 AND 6/6 AT MOST PLACES EAST OF MARQUETTE AND ESCANABA. THE
CLOUDS AND SHOWERS HELD MAXIMUM TEMPERATURES ON 6/5 AND 6/6 IN THE
50S AT MANY PLACES.

EVEN THOUGH THERE WERE MORE CLOUDS AND A FEW LIGHT SHOWERS OVER THE
WEST AND FAR SOUTH CENTRAL NEAR THE WISCONSIN BORDER ON 6/7 THROUGH
6/9 ON THE EDGE OF THE DRY AIRMASS ASSOCIATED WITH THE HUDSON BAY
HIGH PRESSURE SYSTEM...THIS HIGH SUPPRESSED PRECIPITATION COMPLETELY
OVER THE NORTH CENTRAL AND EAST. MEAN DAILY TEMPERATURES AVERAGED
NEAR NORMAL ON THESE THREE DAYS.

THE LIGHT SOUTHERLY FLOW IN ADVANCE OF A COOL FRONT ADVECTED SOME
WARMER AND MOISTER AIR OVER UPPER MICHIGAN ON 6/10 INTO 6/11...
BRINGING MORE CLOUDS AND SCATTERED SHOWERS TO THE ENTIRE AREA. BUT
ANY RAINFALL WAS LESS THAN 0.10 TO AT MOST 0.25 INCH. MEAN DAILY
TEMPERATURES ON 6/10 ROSE TO 5 TO 10 DEGREES ABOVE AVERAGE BUT THEN
FELL CLOSE TO NORMAL ON 6/11 AND 6/12 AS A WEAK CANADIAN HIGH
PRESSURE SYSTEM BUILT INTO THE UPPER LAKES IN THE WAKE OF THE 6/11
COLD FRONTAL PASSAGE. SOME DENSE FOG DEVELOPED OVER MAINLY THE
INTERIOR EAST HALF DURING THE EARLY MORNING HOURS ON 6/12.

HIGH PRESSURE OVER ONTARIO REMAINED A DOMINANT INFLUENCE ON UPPER
MICHIGAN WEATHER ON 6/13 THROUGH 6/15. ALTHOUGH SOME LIGHT SHOWERS
ASSOCIATED WITH A LOW PRESSURE TROUGH MOVING EAST THROUGH MINNESOTA
PUSHED INTO THE WEST HALF ON 6/15...THE DRYNESS OF THE AIRMASS
ASSOCIATED WITH THE HIGH LIMITED THE COVERAGE AND INTENSITY OF THESE
SHOWERS BEFORE THEY DISSIPATED AFTER PUSHING INTO THE EAST. WITH A
COOL NORTHEAST WIND OFF THE CHILLY WATERS OF LAKE SUPERIOR...MEAN
DAILY TEMPERATURES ON 6/13 AND 6/14 RAN UP TO 5 DEGREES BELOW
NORMAL. READINGS WERE CLOSE TO NORMAL ON 6/15 AS THE SOUTHERLY FLOW
AHEAD OF THE INCOMING TROUGH DREW SOME WARMER AIR INTO THE UPPER
GREAT LAKES.

AS AN UPPER TROUGH DEEPENED INTO THE GREAT LAKES...A COLD FRONT
SWUNG THROUGH UPPER MICHIGAN ON 6/16...BRINGING SOME SCATTERED
SHOWERS AND A FEW THUNDERSTORMS TO MAINLY THE WEST HALF. ALTHOUGH
MOST PLACES THAT SAW THE SHOWERS PICKED UP NO MORE THAN 0.10 INCH OF
RAIN...AS MUCH AS 0.28 INCH FELL AT COPPER HARBOR. AN UNSEASONABLY
COOL AIRMASS FOLLOWED FOR 6/17 INTO 6/19...DROPPING A NEAR NORMAL
AVERAGE TEMPERATURE ON 6/16 TO AS MUCH AS 10 TO 15 DEGREES BELOW
NORMAL ON 6/17 AND 6/18. LOW TEMPERATURES IN THE 30S WERE COMMON
OVER THE INTERIOR ON 6/18 AND 6/19...AND THE THERMOMETER READ IN THE
UPPER 20S OVER THE COLDEST LOCATIONS ON THESE MORNINGS. WATERSMEET
IN GOGEBIC COUNTY WAS THE COLDEST LOCATION WITH A MINIMUM
TEMPERATURE OF 28 ON 6/18. MEAN DAILY TEMPERATURES ON 6/19 REBOUNDED
TO NEAR NORMAL AS THE CANADIAN HIGH PRESSURE SHIFTED TO THE EAST AND
A RETURN SOUTHWEST FLOW DREW WARMER AIR BACK INTO THE UPPER GREAT
LAKES.

THE STRENGTHENING SOUTHWEST FLOW BETWEEN THE DEPARTING HIGH PRESSURE
SYSTEM AND LOW PRESSURE DEVELOPING IN THE PLAINS DREW MOISTER AIR
BACK INTO THE UPPER GREAT LAKES ON 6/20 THROUGH 6/22. AS THE WARM
FRONT ASSOCIATED WITH THE PLAINS LOW MOVED TO THE NORTH...SHOWERS
AND SOME THUNDERSTORMS OVERSPREAD UPPER MICHIGAN. THESE SHOWERS
DROPPED SOME HEAVY RAIN...ESPECIALLY FROM LATE ON 6/20 THROUGH 6/21
OVER THE WESTERN U.P. RAINFALL DURING THIS TIME EXCEEDED 1.50 TO
2.00 INCHES AT MANY SPOTS OVER THE WEST. SOME OF THE MORE IMPRESSIVE
TOTALS WERE 2.57 INCHES AT BARAGA...2.46 INCHES AT IRONWOOD AND 2.36
INCHES AT HOUGHTON. THE LEAST RAIN FELL IN A STRIPE OVER THE SOUTH
CENTRAL FROM IRON MOUNTAIN TO ESCANABA AND MANISTIQUE. NO MORE THAN
ABOUT 0.25 INCH WAS THE RULE AT MANY LOCATIONS IN THIS AREA...WITH
AS LITTLE AS 0.08 INCH REPORTED AT GARDEN CORNERS IN DELTA COUNTY.
WITH THE WIDESPREAD CLOUD COVER AND SHOWERS...MAXIMUM TEMPERATURES
ON 6/21 AND 6/22 WERE MAINLY IN THE COOL 60S...RESULTING IN NEAR
NORMAL MEAN DAILY TEMPERATURES FOR 6/20 THROUGH 6/22. THERE WERE
ALSO AREAS OF FOG NORTH OF THE WARM FRONT ON 6/21 INTO 6/22...AND
THIS FOG BECAME DENSE AT TIMES OVER THE KEWEENAW.

THE PLAINS LOW MOVED NORTH INTO CANADA BY 6/23...LIFTING THE WARM
FRONT ACROSS UPPER MICHIGAN. AS A RESULT...A MUCH WARMER AIRMASS
DOMINATED THE AREA ON 6/23 THROUGH 6/27...WITH MEAN DAILY
TEMPERATURES AROUND 10 DEGREES ABOVE AVERAGE DURING THIS MORE
SUMMER-LIKE PERIOD. THE PASSAGE OF A COUPLE WEAK LOW PRESSURE
TROUGHS CAUSED NOTHING MORE THAN SOME ISOLATED SHOWERS AND
THUNDERSTORMS ON 6/23 AND 6/24. THE MERCURY ROSE TO 90 AT A COUPLE
OF PLACES WITH MORE SUNSHINE ON 6/25...THE ONLY DAY IN JUNE WHEN
TEMPERATURES REACHED THAT LEVEL. PELKIE IN BARAGA COUNTY NEAR THE
HOUGHTON COUNTY LINE WAS THE WARMEST SPOT WITH A MAXIMUM TEMPERATURE
OF 91 ON 6/25.

AS A STRONGER DISTURBANCE MOVED INTO THE UPPER GREAT LAKES ON 6/26
AND INTERACTED WITH THE WARM AND UNSTABLE AIRMASS IN PLACE...MORE
NUMEROUS SHOWERS AND THUNDERSTORMS DEVELOPED IN THE AFTERNOON AND
CONTINUED THROUGH THE EVENING. SOME OF THE THUNDERSTORMS LATE IN THE
AFTERNOON AND EVENING ON 6/26 TURNED SEVERE WITH DAMAGING WINDS OVER
THE NORTHERN TIER OF UPPER MICHIGAN. HOUGHTON CLOCKED A WIND GUST AS
HIGH AS 56 MPH UNDER ONE OF THE STRONGER STORMS. HEAVY RAIN FELL AT
SOME LOCATIONS AS WELL...INCLUDING AS MUCH AS 2.04 INCHES AT
STAMBAUGH IN IRON COUNTY. THE APPROACH OF ANOTHER DISTURBANCE ON
6/27 CAUSED MORE SHOWERS AND THUNDERSTORMS IN THE AFTERNOON AND
EVENING THAT DAY. ONE SEVERE STORM STRUCK MARQUETTE COUNTY IN THE
EVENING ON 6/27...BOMBARDING A SITE NEAR CHAMPION WITH QUARTER-SIZED
HAIL AND 1.26 INCHES OF RAIN. MENOMINEE PICKED UP 1.22 INCHES OF
RAIN...AND GLADSTONE IN DELTA COUNTY REPORTED 1.14 INCHES UNDER SOME
OTHER HEAVIER SHOWERS.

AS A TROUGH DEEPENED INTO THE GREAT LAKES...A COLD FRONT CROSSED
UPPER MICHIGAN ON 6/28. MEAN DAILY TEMPERATURES ON 6/28 AND 6/29
DROPPED TO AROUND 5 DEGREES BELOW NORMAL. THERE WERE NUMEROUS
SHOWERS ON 6/28 INTO EARLY 6/29 OVER UPPER MICHIGAN AS THE FRONT AND
AN UPPER DISTURBANCE CROSSED THE AREA. SOME PLACES LOGGED 0.25 INCH
OR MORE PRECIPITATION...INCLUDING 0.50 INCH AT MENOMINEE. PATCHY
DENSE FOG PLAGUED LOCATIONS NEAR LAKE SUPERIOR ON 6/28 AS WELL. HIGH
PRESSURE BUILDING INTO ONTARIO BROUGHT DRIER WEATHER FOR THE LATER
ON 6/29 AND 6/30. MEAN DAILY TEMPERATURES ON 6/30 RETURNED TO NEAR
NORMAL WITH MORE SUNSHINE.

                          AUGUST FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING AN EQUAL CHANCE
OF AN ABOVE AND BELOW NORMAL MONTHLY MEAN TEMPERATURE AND ABOVE AND
BELOW NORMAL MONTHLY PRECIPITATION OVER ALL OF UPPER MICHIGAN IN
AUGUST 2013.

                         AUGUST CLIMATOLOGY

AFTER PEAKING IN JULY...AVERAGE TEMPERATURES IN AUGUST BEGIN TO
SLIDE AS THE SUN CONTINUES ITS LATE YEAR JOURNEY SOUTH. POSSIBLE
SUNSHINE DECLINES FROM 892 MINUTES ON 8/1 TO 804 MINUTES ON 8/31...
AND AVERAGE TEMPERATURES ARE ONE TO TWO DEGREES LOWER THAN IN JULY.

BUT SUMMER ACROSS UPPER MICHIGAN IS NOT OVER YET IN AUGUST. ALTHOUGH
100 DEGREE TEMPERATURES ARE RARE DURING THE EIGHTH MONTH...SUCH HEAT
IS NOT UNPRECEDENTED. IN AUGUST 2001...BARK RIVER IN DELTA COUNTY
SAW THE MERCURY RISE AS HIGH AS 102 ON 8/7 AND 101 ON 8/6 DURING A
TORRID HEAT WAVE BETWEEN 8/5 AND 8/8. 8/5/47 GOES DOWN IN THE RECORD
BOOKS OVER MUCH OF UPPER MICHIGAN AS THE HOTTEST AUGUST DAY SINCE
RECORDS BEGAN. IRON MOUNTAIN (101)...IRONWOOD (101)...AND DOWNTOWN
MARQUETTE (102) ALL RECORDED THEIR ALL TIME HIGHEST AUGUST
TEMPERATURES ON THAT SWELTERING DAY. AUGUST 1947 IS ALSO THE WARMEST
AUGUST ON RECORD AT IRONWOOD (73.4 DEGREE AVERAGE TEMPERATURE)...
IRON MOUNTAIN (72.4)...AND NEWBERRY (69.6).

ALTHOUGH SUMMER HEAT CAN STILL GRIP THE AREA IN AUGUST...COOLER AIR
MASSES MAKE MORE FREQUENT VISITS TO THE NORTHERN GREAT LAKES DURING
THE EIGHTH MONTH. AS THE NIGHTS LENGTHEN IN AUGUST...FROST BECOMES
A  GREATER THREAT OVER ESPECIALLY INTERIOR LOCATIONS AWAY FROM THE
MODERATING INFLUENCE OF THE GREAT LAKES (LAKE WATER TEMPERATURES
TYPICALLY REACH THEIR HIGHEST LEVELS IN MID TO LATE AUGUST). THE
LOW  TEMPERATURE AT IRONWOOD HAS REACHED FREEZING AS EARLY AS
8/4...IN  1907. BETWEEN 8/19 AND 8/21 IN 2000...SOME SHELTERED
INLAND LOCATIONS REPORTED FROST. AUGUST 2004 WAS THE COOLEST EIGHTH
MONTH IN RECENT MEMORY. MONTHLY TEMPERATURES AVERAGED 3 TO 6 DEGREES
BELOW NORMAL...AND AUGUST 2004 GOES DOWN IN THE RECORD BOOKS IN THE
LIST OF TOP 10 COOLEST AT ALMOST ALL REPORTING STATIONS. PATCHY
FROST WAS OBSERVED OVER THE COOLER INLAND LOCATIONS IN AUGUST 2004
BETWEEN 8/19 AND 8/21.

PRECIPITATION IN AUGUST CAN BE QUITE VARIABLE DEPENDING ON THE
FREQUENCY OF THUNDERSTORMS. THE DRIEST EIGHTH MONTH IN RECENT YEARS
OCCURRED IN 2008...WHEN MANY PLACES ENDURED ONE OF THE TOP FIVE
DRIEST AUGUSTS ON RECORD IN THE ABSENCE OF MUCH CONVECTION. ONLY
0.42 INCH AND 0.44 INCH OF RAIN FELL IN THE CITY OF MARQUETTE AND AT
THE MARQUETTE NWS IN THAT DRY MONTH...WHICH GOES DOWN IN THE RECORD
BOOKS AS THE DRIEST AUGUST ON RECORD AT THOSE LOCATIONS. 2007 ALSO
FEATURED A TOP TEN DRIEST EIGHTH MONTH AT MOST LOCATIONS THAT HELPED
DROP LAKE SUPERIOR TO A RECORD LOW LEVEL. ON THE OTHER HAND...SLOW
MOVING THUNDERSTORMS CAN STILL THREATEN THE UPPER PENINSULA WITH
TORRENTIAL RAIN. A TOTAL OF 11.15 INCHES OF RAIN INUNDATED IRONWOOD
DURING AUGUST 1941.

                           OUTLOOK FOR FALL

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING A GREATER THAN
CLIMATOLOGICAL CHANCE OF AN ABOVE NORMAL 3-MONTH MEAN TEMPERATURE
BUT AN EQUAL CHANCE OF ABOVE AND BELOW NORMAL 3-MONTH PRECIPITATION
OVER ALL OF UPPER MICHIGAN IN SEPTEMBER THROUGH NOVEMBER 2013.
