September 2009 Recap

...DRY START...WET END...

THIS SEPTEMBER WILL LIKELY BE REMEMBERED FOR THE DRY START TO THE
MONTH WITH NEARLY NO PRECIPITATION FALLING ACROSS THE NORTH WOODS
OVER THE FIRST 20 DAYS OF THE MONTH. HOWEVER...THANKS TO SOME MUCH
NEEDED RAINFALL OVER THE LAST WEEK AND A HALF...OVERALL RAINFALL
DEFICITS WERE NOT AS EXTREME AS THEY COULD HAVE BEEN...WITH ONE
EXCEPTION. THAT EXCEPTION WAS EASTERN UPPER MICHIGAN WHERE THEY
MANAGED TO STAY WELL UNDER AN INCH FOR THE MONTH...ALLOWING SAULT
SAINTE MARIE TO RECORD THE DRIEST SEPTEMBER IN RECORDED HISTORY.

WITH THE PLEASANT CONDITIONS SEEN OVER THE FIRST TWO THIRDS OF THE
MONTH...DAYTIME HIGHS WERE SLIGHTLY ABOVE NORMAL...WHILE OVERNIGHT
LOWS FELL CLOSER TO NORMAL OR JUST BELOW NORMAL. AFTER 4 MONTHS OF
BELOW NORMAL TEMPERATURES...SEPTEMBER FINALLY SAW A RETURN TO ABOVE
NORMAL TEMPERATURES.

HERE IS A LOOK AT HOW SOME LOCATIONS FARED WITH RESPECT TO THEIR
AVERAGE TEMPERATURES DURING SEPTEMBER 2009 (MAX...MIN...AND MEAN
