Near Normal Temperatures for September

 September 2013 Highlights:

(1) Periodic warm and cold spells throughout the month resulted in almost perfectly normal average September temperatures across northern Michigan.  Per the usual, summer weather refused to give up without a fight, as evident on the 10th when several locations reported high temperatures at or above 90 degrees.  Also, per the normal, most areas experienced their first freeze of the young fall season.   

(2) Rainfall followed the theme started this past summer, with a definite trend of the heaviest rains falling across eastern upper Michigan, while amounts tapered off significantly south of the Straits.  Sault Ste Marie once again came in well above normal, experiencing their 8th wettest September on record.  Rainfall averaged below normal for nearly all of northern lower Michigan, although no top ten driest records were broken.
