May 2011 Review

Both precipitation and temperatures fell well within the realm of what is considered normal for May across northern Michigan.  Fortunately, rather persistent rains led to a rather healthy green-up across the north woods, and helped kick the growing season into an excellent start.  For the first time in the last several years, no snow was reported, or observed, for the month.

While there were periodic bouts of severe weather, mainly consisting of isolated reports of large hail and damaging wind gusts, the vast majority of severe weather remained well south and west of northern Michigan.
