Frost advisory, freeze warning issued for Lower Peninsula
A frost advisory is in effect for parts of Michigan, a sign that there's a reason for the age-old advice about not planting until after Mother's Day.

And, like mothers and grandmothers around Michigan warn, plants may be damaged if not protected outside.
Wayne County is not included in the frost advisory, according to weather service maps.

Temperatures in Metro Detroit are expected around the mid-50s on Saturday, with a low of in the low 40s. Sunday should see a high in the mid-50s.
