After a scorching hot summer in 2012 which featured widespread drought along with Detroit's hottest summer on record (tied with 2005), Southeast Michigan and the entire eastern half of the country have fared much better this year with regard to both heat and rainfall.  In fact, high temperatures have only reached 90 degrees three times thus far in Flint and twice in the Tri-Cities, while Detroit has yet to break the 90-degree barrier.  In addition, all three locations are currently amidst their 4th wettest year on record as of July 10th.  See how this summer ranks historically and how it compares to last year below:
