Here is a more detailed both CONUS and for Michigan, October Climate Summary.

By waiting until the 8th, I can get the maps from NCEI (National Center for Environmental Information). I have added graphs from xmACIS for the daily temperature and precipitation plus I have the monthly climate summary from Grand Rapids and Gaylord.

Enjoy the warm weather this week because it will get much colder next week and parts of Michigan may even see their first snowfalls by Tuesday. Happy Halloween!

This shows our transition point from warmer to cooler weather.

A Very Dry May is Expected to be Followed by a Not all the Wet June over Southern Lower Michigan (at least through mid June)

May in Southwest Michigan was one of the top 10 driest on Record, the fist half of June is not expected to be all that much wetter.
