Frost/Freeze Products End Today

Temperatures so far this September have been right about normal across much of northern Michigan, but with many mornings dipping well into the 30s and even 20s for numerous locations across the region. This has resulted in many areas inland away from the Great Lakes having received at least one frost over the past few weeks, with quite a few locations having noted several frosty mornings. Based on historical data (see list below), this timing during the first few weeks of September is right about normal for this time of year.

Given that many areas have experienced at least one frost this season, the National Weather Service in Gaylord will end all frost and freeze products effective today - Monday, September 30th. Simply put, that means we will no longer issue any frost advisories or freeze warnings, and will no longer mention frost in any forecasts.

If you have any questions about this, please contact Jim Keysor at (989) 731-3384.
