Spring 2011 Review

A rather wet spring across northern Michigan, with several locations experiencing one of their top ten wettest springs on record.  This helped alleviate rapid growing late winter and early spring drought conditions over the tip of the mitt and eastern Upper Michigan.  Despite no observed snow during May, snowfall was also much above normal for the season.

Average temperatures were about on par with spring normals, with no large deviations from what is typically experienced during a northern Michigan spring.

A much more active start to the severe weather season when compared to the last couple of years.  However, no large severe weather events occurred, with just several days of sporadic severe wind and hail reports.
