      From 90's Tuesday to frost Friday night

      Some spots will see the first frost of the season Friday night.

      As we trek towards autumn, the days are getting shorter and some of the coolest temperatures in months are on the way.

      Northern Michigan has lost about three hours of daylight since mid-June as the amount of daylight continues to shrink. That increasing lack of daylight allows for cooler weather to build in the northern reaches of the hemisphere with a little of that arriving here late this week.

      Winds have shifted northerly across Northern Michigan Thursday and will continue to remain brisk through Friday. Temperatures Thursday will only reach the low/mid-60's across Lower Michigan with upper-50's in the Eastern U.P. That cooler air crossing the warm reservoir of warm water in the Great Lakes will lead to lake effect clouds and also lake induced rain showers downwind of the lakes Thursday afternoon/night into Friday morning. Any showers will be light and not amount to much, but they will be passing by.

      Temperatures Friday will only reach the mid/upper-50's areawide although the sunshine will return. Following that, a potentially frosty night is setting up Friday night. Frost is not at this time forecasted to be widespread, but our colder locations inland away from the Great Lakes will see low-30's with even a few upper-20's possible. If you still have that garden in bloom, you may want to consider covering it up Friday night.

      The weekend starts pleasant with 60's and sunshine Saturday.
