August 2013 Highlights:

(1) A tale of two halves regarding monthly temperatures. The first half of the month was well below normal, with all locations running average temperature departures of several degrees below normal by August 15th.  Temperatures rebounded quickly from thereafter, with almost every day the second half of the month running above average.  In the end, it essentially all evened out, with average monthly temperatures ending just about normal for all of northern Michigan.

(2) While rainfall was rather consistent across eastern upper Michigan (7th wettest August on record at Sault Ste Marie), conditions turned abnormally dry for much of the area south of the Straits through the first 25 days of the month.  Showers and thunderstorms became a little more common during the last week across northern Lower, some of which brought exceptionally heavy rains (3 to 5 inches on the 27th from Grand Traverse Bay to near Cadillac).  Unfortunately, much of northeast Lower missed out on the heavy rains, receiving only about 25 percent of their monthly normal rainfall for August (see map below).
