                        AUGUST 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 2014.

                         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 EQUAL CHANCES OF
AN ABOVE AND BELOW NORMAL 3-MONTH AVERAGE TEMPERATURE AND ABOVE AND
BELOW NORMAL 3-MONTH PRECIPITATION OVER ALL OF UPPER MICHIGAN IN
SEPTEMBER THROUGH NOVEMBER 2014.

GO TO HTTP://WWW.WEATHER.GOV/CLIMATE/L3MTO.PHP TO ACCESS DETAILED
LOCAL THREE-MONTH AVERAGE TEMPERATURE OUTLOOKS FOR A NUMBER OF SITES
IN UPPER MICHIGAN.

CHECK OUT HTTP://WWW.CPC.NCEP.NOAA.GOV FOR MORE INFORMATION ABOUT
THE CLIMATE PREDICTION CENTER AND MORE LONG RANGE PREDICTIONS.

NOTE THAT STATISTICS FOR THE NATIONAL WEATHER SERVICE OFFICE IN
NEGAUNEE TOWNSHIP ARE BASED ON RECORDS WHICH BEGAN IN OCTOBER 1961.
THIRTY YEAR NORMALS USED ARE FOR THE PERIOD OF 1981 THROUGH 2010.
NOTE ALL TEMPERATURES ARE IN FAHRENHEIT AND PRECIPITATION IS IN
INCHES. ALL CLIMATE DATA LISTED IN THIS PRODUCT ARE UNOFFICIAL. FOR
OFFICIAL DATA...PLEASE REFER TO THE NATIONAL CLIMATIC DATA CENTER.
ALSO NOTE THIS DISCUSSION DOES NOT INCLUDE DATA FROM CHIPPEWA AND
MACKINAC COUNTIES.
