                        AUGUST WEATHER SUMMARY

MORE TO COME LATER.

                         SEPTEMBER FORECAST

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

                        SEPTEMBER CLIMATOLOGY

AVERAGE TEMPERATURES IN SEPTEMBER BEGIN TO FALL SHARPLY...ABOUT 8 TO
9 DEGREES LOWER THAN IN AUGUST...AS SUMMER TRANSITIONS TO AUTUMN AND
DAYLIGHT GROWS SHORTER. THE AUTUMNAL EQUINOX THIS YEAR IS AT 444 PM
EDT ON 9/22. POSSIBLE SUNSHINE IN SEPTEMBER DECLINES FROM 800
MINUTES ON 9/1 TO 706 MINUTES ON 9/30...A DECREASE OF 3 TO 4 MINUTES
EACH DAY.

ALTHOUGH THE DAYS GROW SHORTER DURING THE NINTH MONTH...MID SUMMER
LIKE WARMTH CAN STILL GRIP UPPER MICHIGAN DURING SEPTEMBER. ON
9/12/98...RESIDENTS OF IRON MOUNTAIN SIZZLED IN 98-DEGREE HEAT. BOTH
IRON MOUNTAIN AND IRONWOOD RECORDED HIGH TEMPERATURES ABOVE 90 FIVE
DAYS IN A ROW DURING A TORRID MID SEPTEMBER HEATWAVE BETWEEN 9/8 AND
9/12 IN 1931. WITH TEMPERATURES AVERAGING 7 TO 8 DEGREES ABOVE
NORMAL...SEPTEMBER 1931 GOES DOWN IN THE RECORD BOOKS AS THE WARMEST
SEPTEMBER EVER OBSERVED AT IRON MOUNTAIN AND IRONWOOD. MORE RECENTLY
IN 2002...MANY PLACES BAKED IN 90-DEGREE HEAT FOR THREE DAYS IN A
ROW ON 9/7 THROUGH 9/9.

MONTHLY TEMPERATURES RAN 3 TO 8 DEGREES ABOVE NORMAL IN SEPTEMBER
2004...WHICH IS THE WARMEST SEPTEMBER SINCE RECORDS BEGAN AT
ONTONAGON AND THE MARQUETTE NWS. THE MONTHLY AVERAGE TEMPERATURE OF
61.8 AT THE MARQUETTE NWS WAS ONLY A TENTH OF A DEGREE LOWER THAN
THE 61.9 READING OBSERVED IN JULY 2004. SEPTEMBER 2004 ALSO RANKS IN
THE LIST OF TOP TEN WARMEST AT IRON MOUNTAIN...MARQUETTE
CITY...NEWBERRY...MUNISING...AND IRONWOOD. SEPTEMBER 2009 WAS ALSO
QUITE BALMY WITH MONTHLY AVERAGE TEMPERATURES 4 TO 6 DEGREES ABOVE
THE 1971-2000 MEAN. THAT MONTH WAS AMONG THE TOP 10 WARMEST
SEPTEMBERS AT MOST LOCATIONS IN UPPER MICHIGAN.

BUT WINTER OFTEN MAKES ITS FIRST RETURN BY LATE IN THE MONTH. THE
GROWING SEASON ENDS EVERYWHERE EXCEPT ALONG THE WARMER GREAT LAKES
SHORES DURING SEPTEMBER WITH AN INCREASED PROBABILITY OF KILLING
FROST. RECORD LOW TEMPERATURES OVER INLAND AREAS FALL INTO THE 20S
DURING THE MONTH AND EVEN INTO THE UPPER TEENS AT MANY LOCATIONS
TOWARD MONTHS END. ON 9/22/95...THE WESTERN UPPER PENINSULA WAS
STRUCK WITH AN EARLY SEASON SNOWSTORM. IRONWOOD PICKED UP 6.5
INCHES...AND HOUGHTON ALSO SAW 3 INCHES OF THE WHITE STUFF THAT DAY.
AT LEAST AN INCH OF SNOW HAS FALLEN ON PORTIONS OF UPPER MICHIGAN
DURING LATE SEPTEMBER IN 1965...1974...1989...AND 1993.

AS THE JET STREAM SINKS FARTHER SOUTH DURING SEPTEMBER AND INTERACTS
WITH FAIRLY WARM AND HUMID AIRMASSES STILL RESIDENT OVER THE UNITED
STATES...AVERAGE MONTHLY PRECIPITATION OVER MUCH OF UPPER MICHIGAN
PEAKS AT A YEARLY MAXIMUM BETWEEN 3.5 AND 4.0 INCHES. ALTHOUGH
CONVECTION OCCURS LESS FREQUENTLY THAN DURING MID SUMMER...
THUNDERSTORMS STILL PRESENT A SEVERE WEATHER AND HEAVY RAIN THREAT.
IRONWOOD WAS INUNDATED WITH 10.74" OF RAIN DURING SEPTEMBER 1926.

                  OUTLOOK FOR FALL INTO EARLY WINTER

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING A GREATER THAN
CLIMATOLOGICAL CHANCE OF AN ABOVE NORMAL 3-MONTH MEAN TEMPERATURE
OVER ALL OF UPPER MICHIGAN IN OCTOBER THROUGH DECEMBER 2013. THE CPC
ALSO EXPECTS A GREATER CHANCE OF ABOVE NORMAL 3-MONTH PRECIPITATION
OVER UPPER MICHIGAN DURING OCTOBER THROUGH DECEMBER EXCEPT OVER THE
FAR EAST...WHERE THE FORECAST SHOWS AN EQUAL CHANCE OF ABOVE AND
BELOW NORMAL 3-MONTH PRECIPITATION.

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
