...LAKE SUPERIOR WATER LEVELS CONTINUE STEADY REBOUND IN JULY...

THANKS TO SOME HEAVY SPRING AND EARLY SUMMER PRECIPITATION...LAKE
SUPERIOR WATER LEVELS ROSE STEADILY IN JULY...BY ABOUT 5 INCHES FROM
7/1 TO 7/31 AND TO WITHIN ABOUT 3 INCHES OF NORMAL BY 7/31. ALTHOUGH
THERE WAS ALSO SOME HEAVY PRECIPITATION IN THE LAKE MICHIGAN/HURON
DRAINAGE BASINS...HIGHER WATER TEMPERATURES AND GREATER EVAPORATION
LIMITED THE RISE IN WATER LEVEL ON THOSE LAKES TO LESS THAN AN INCH.
THE WATER LEVEL ON LAKES MICHIGAN/HURON REMAINED ABOUT 19 INCHES
BELOW AVERAGE ON 7/31.

                        JULY CLIMATE HIGHLIGHTS

HIGHEST REPORTED TEMPERATURE...95 AT MUNISING ON 7/16

LOWEST REPORTED TEMPERATURE...32 AT KENTON IN FAR SOUTHERN HOUGHTON
                               COUNTY ON 7/2

HIGHEST AVERAGE TEMPERATURE...68.5 DEGREES AT IRON MOUNTAIN

LOWEST AVERAGE TEMPERATURE...62.5 DEGREES AT COPPER HARBOR

HIGHEST MONTHLY PRECIPITATION...8.89 INCHES AT WATERSMEET

LOWEST MONTHLY PRECIPITATION...2.43 INCHES AT IRON MOUNTAIN

THE WEATHER IN JULY 2013 FEATURED STRETCHES OF BOTH VERY WARM AND
VERY COOL WEATHER AS THE UPPER AIR FLOW TRANSITIONED BETWEEN PERIODS
DOMINATED BY AN UPPER TROUGH AND A RIDGE OVER THE GREAT LAKES. SINCE
THESE EXTREMES TENDED TO AVERAGE OUT...THE MEAN JULY TEMPERATURE
ACROSS UPPER MICHIGAN ENDED UP WITHIN A DEGREE OF NORMAL AT ALL
REPORTING LOCATIONS. THE MEAN MONTHLY TEMPERATURE RANGED FROM 62.5
TO 68.5 DEGREES...5 TO 8 DEGREES HIGHER THAN THE JUNE AVERAGE.

JULY WAS ANOTHER WET MONTH OVERALL...THE SIXTH IN A ROW OF ABUNDANT
PRECIPITATION AT MOST SITES. FREQUENT SHOWERS AND THUNDERSTORMS THAT
FELL WHEN THE TROUGH WAS DEEPER OR WHEN THE UPPER AIR PATTERN WAS
TRANSITIONING DUMPED 6 INCHES OR MORE OF RAIN AT MANY PLACES IN A
SWATH OVER THE WEST FROM IRONWOOD THROUGH THE KEWEENAW AND EAST OF A
LINE FROM ESCANABA TO MUNISING...WITH 8 INCHES OR MORE AT A NUMBER
OF SPOTS. THIS RAINFALL IS 150 TO 250 PERCENT OF THE MONTHLY
AVERAGE. SOME OF THE MORE IMPRESSIVE TOTALS INCLUDE 8.89 INCHES AT
WATERSMEET IN GOGEBIC COUNTY...8.82 INCHES AT SENEY IN SCHOOLCRAFT
COUNTY...8.46 INCHES AT NEWBERRY...AND 8.15 INCHES AT MOHAWK IN
KEWEENAW COUNTY. THESE PRECIPITATION AMOUNTS QUALIFY JULY 2013 AS
ONE OF THE TOP FIVE WETTEST SEVENTH MONTHS ON RECORD. IN FACT...THE
MONTH ENDS UP AS THE WETTEST JULY ON RECORD AT NEWBERRY...WHERE THE
REPORTED 8.46 INCHES IS ALMOST 275 PERCENT OF THE NORMAL 3.10 INCHES.

THE LEAST PRECIPITATION IN JULY OCCURRED OVER THE CENTRAL...BUT EVEN
THERE MOST PLACES REPORTED ABOVE NORMAL RAINFALL...AND EVEN A TOP
TEN WETTEST JULY AT A FEW SPOTS. THE EXCEPTION WAS IRON MOUNTAIN...
WHICH TENDED TO MISS SOME OF THE HEAVIER SHOWERS THAT IMPACTED
NEARBY LOCATIONS. ONLY 2.43 INCHES OF RAIN FELL THERE...ABOUT 70
PERCENT OF THE NORMAL 3.45 INCHES. LARGE VARIATIONS IN PRECIPITATION
OVER SHORT DISTANCES IS NOT UNPRECEDENTED IN THE SUMMER. JUST DOWN
THE ROAD IN SOUTHEAST DICKINSON COUNTY...NORWAY LOGGED A MORE
REPRESENTATIVE 4.06 INCHES.

COOL CANADIAN AIRMASSES ASSOCIATED WITH A DEEPER TROUGH TENDED TO
DOMINATE THE AREA EARLY IN JULY AND DURING THE LAST 10 DAYS. THE
THERMOMETER READ IN THE 30S AT SOME PLACES IN THE EARLY MORNING ON
7/2 AND 7/24. BUT THE COOLEST PERIOD WAS ON 7/26 THROUGH 7/28...WHEN
THE TROUGH WAS DEEPEST AND THERE WERE NUMEROUS SHOWERS UNDER A GRAY
OVERCAST. MANY NEW DAILY RECORD LOW MAXIMUM TEMPERATURES WERE
ESTABLISHED ON 7/27 AND 7/28...WHEN THE MERCURY ROSE NO HIGHER THAN
THE 50S AT MOST PLACES AND MEAN DAILY TEMPERATURES AVERAGED 15 TO 20
DEGREES BELOW NORMAL EVEN THOUGH OVERNIGHT LOWS WERE NOT EXCESSIVELY
COOL. THE 55-DEGREE HIGH AT IRON MOUNTAIN ON 7/28 WAS THE RECORD
LOWEST MAXIMUM AT THAT LOCATION NOT ONLY FOR THE DATE BUT THE WHOLE
MONTH OF JULY AS WELL.

FOLLOWING THE EARLY MONTH COOL SNAP...A VERY WARM AIRMASS INVADED
THE UPPER LAKES ON 7/5 AND 7/6. SOME LOCATIONS SAW THE THERMOMETER
HIT 90 FOR THE FIRST TIME OF THE YEAR ON 7/6. BUT THE WARMEST PERIOD
WAS THE WEEK FROM 7/13 INTO 7/19...WHEN AN ANOMALOUSLY STRONG UPPER
RIDGE BUILT OVER THE GREAT LAKES AND LIFTED MEAN DAILY TEMPERATURES
10 TO 15 DEGREES ABOVE NORMAL. AT LEAST A FEW PLACES REPORTED
90-DEGREE HIGH TEMPERATURES EACH AFTERNOON FROM 7/14 THROUGH 7/18...
AND THE MERCURY FAILED TO DROP BELOW 70 AT SOME LOCATIONS IN THE
EARLY MORNINGS OF 7/17...7/18 AND 7/19. THE PASSAGE OF A COLD FRONT
ON 7/19 ASSOCIATED WITH A TROUGH DISPLACING THE UPPER RIDGE ENDED
THIS WARM SPELL.

THE WETTEST PERIODS IN JULY WERE FROM LATE ON 7/6 INTO 7/8...THE
AFTERNOON ON 7/17 INTO 7/19...AND LATE ON 7/25 THROUGH 7/28. A
NEARLY STATIONARY FRONT WAS THE FOCUS FOR SHOWERS AND THUNDERSTORMS
DURING THE 7/6 INTO 7/8 TIME PERIOD. AS A PAIR OF UPPER DISTURBANCES
INTERACTED WITH THIS BOUNDARY AND A HUMID AIRMASS IN PLACE...SOME
VERY HEAVY RAIN FELL OVER MAINLY WESTERN UPPER MICHIGAN. SEVERAL
PLACES IN THAT AREA MEASURED 2 OR MORE INCHES OF RAIN DURING THIS
TIME...WITH 3.83 INCHES AT WATERSMEET. MARENISCO LOGGED 4.12 INCHES
OF RAIN IN THE EARLY MORNING ON 7/7 ALONE.

AS THE UPPER TROUGH BEGAN TO DEEPEN INTO THE GREAT LAKES ON 7/17
INTO 7/19 AND LIFTED THE WARM AND UNSTABLE AIRMASS IN PLACE...WAVES
OF SHOWERS AND THUNDERSTORMS...SOME OF WHICH TURNED SEVERE AND/OR
DROPPED TORRENTIAL DOWNPOURS...RODE ACROSS THE U.P. MOST PLACES AWAY
FROM THE SOUTH CENTRAL SAW 1 TO 2 INCHES OF RAIN OR EVEN MORE...WITH
AS MUCH AS 4.09 INCHES AT NEWBERRY...3.35 INCHES AT BIG BAY IN
MARQUETTE COUNTY AND 3.33 INCHES AT MOHAWK IN KEWEENAW COUNTY.
SEVERE STORMS BOMBARDED A FEW SPOTS IN LUCE COUNTY WITH HAIL THE
SIZE OF QUARTERS IN THE AFTERNOON ON 7/17 AND CAUSED WIND DAMAGE AT
SEVERAL PLACES IN MARQUETTE...BARAGA...LUCE AND HOUGHTON COUNTIES IN
THE EVENING ON 7/18. ONE OTHER SEVERE STORM CAUSED WIND DAMAGE IN
DELTA COUNTY IN THE AFTERNOON ON 7/19.

ANOTHER ROUND OF WIDESPREAD SHOWERS OCCURRED FROM LATE IN THE DAY ON
7/25 THROUGH 7/28. AT LEAST 1 TO 2 INCHES OF RAIN FELL OVER UPPER
MICHIGAN DURING THIS PERIOD. THERE WERE ALSO SOME THUNDERSTORMS WITH
TORRENTIAL RAINS ON 7/25 INTO 7/26 BEFORE THE MUCH COOLER AIRMASS
ARRIVED AND ENDED THE DEEPER CONVECTION. RAINFALL TOTALS FROM THE
EVENING ON 7/25 THROUGH THE DAY ON 7/26 WERE PARTICULARLY EXCESSIVE
OVER THE EAST FROM MANISTIQUE TO NEWBERRY. GARDEN CORNERS IN FAR
SOUTHEAST DELTA COUNTY REPORTED 5.08 INCHES OF RAIN ON 7/25 AND
7/26. MANISTIQUE LOGGED 4.85 INCHES DURING THIS SAME TIME. ONE OF
THE THUNDERSTORMS OVER GOGEBIC COUNTY TURNED SEVERE AND CAUSED WIND
DAMAGE IN THE EVENING ON 7/25.

A FINAL SEVERE THUNDERSTORM DROPPED QUARTER-SIZED HAIL IN ALGER
COUNTY IN THE AFTERNOON ON 7/31.

                        JULY WEATHER SUMMARY

MORE TO COME LATER

                          AUGUST FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING A GREATER THAN
CLIMATOLOGICAL CHANCE OF A BELOW NORMAL MONTHLY MEAN TEMPERATURE BUT
EQUAL CHANCES OF 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.
