                         SEPTEMBER FORECAST

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING EQUAL CHANCES OF
AN ABOVE AND BELOW NORMAL MONTHLY MEAN TEMPERATURE AND MONTHLY
PRECIPITATION ACROSS ALL OF UPPER MICHIGAN IN SEPTEMBER 2016.

                        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 1029 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.

SEPTEMBER 2015 WAS QUITE WARM OVER ALL OF UPPER MICHIGAN AND THE
WARMEST NINTH MONTH ON RECORD AT NEWBERRY AND MANISTIQUE THANKS TO
PERSISTENT UPPER RIDGE THAT DOMINATED CENTRAL AND EASTERN NORTH
AMERICA. MOST PLACES EXPERIENCED ONE OF THEIR TOP FIVE WARMEST
SEPTEMBERS IN 2015, WHEN MEAN MONTHLY TEMPERATURES RAN 5 TO 7
DEGREES ABOVE NORMAL. SEPTEMBER 2004 WAS ALSO DOMINATED BY AN UPPER
RIDGE AND QUITE WARM, WITH A MONTHLY AVERAGE TEMPERATURE 3 TO 8
DEGREES ABOVE NORMAL ENOUGH TO PLACE THAT SEPTEMBER AMONG THE TOP
TEN WARMEST AT MOST LOCATIONS. THAT MONTH ENDED UP AS THE WARMEST
SEPTEMBER ON RECORD AT ONTONAGON AND THE MARQUETTE NWS OFFICE. IN
FACT, 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 2009 WAS ALSO QUITE BALMY WITH MONTHLY AVERAGE
TEMPERATURES 4 TO 6 DEGREES ABOVE THE 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 CPC IS FORECASTING A GREATER THAN CLIMATOLOGICAL CHANCE OF AN
ABOVE NORMAL 3-MONTH AVERAGE TEMPERATURE BUT EQUAL CHANGES OF ABOVE
AND BELOW NORMAL 3-MONTH PRECIPITATION OVER ALL OF UPPER MICHIGAN IN
OCTOBER THROUGH DECEMBER 2016.

NEGAUNEE TOWNSHIP ARE BASED ON RECORDS WHICH BEGAN IN OCTOBER 1961.
THIRTY YEAR NORMALS USED ARE FOR THE PERIOD OF 1981 THROUGH 2010.

INCHES. ALL CLIMATE DATA LISTED IN THIS PRODUCT ARE UNOFFICIAL. FOR
