DETROIT – A Winter Storm Warning is in effect for Lenawee, Livingston, Macomb, Monroe, Oakland, Washtenaw and Wayne counties until 12 p.m. Saturday. It’s MLK weekend, so winter storm 2020 will allow for quiet, calm reflection of the occasion’s meaning indoors. Winter Storm 2020 will unleash its heaviest snow Saturday morning, and it will be combined with pounding surf. The warm sector of winter storm 2020 arrives Saturday afternoon. Afternoon highs will be in the low and mid 20s with wind chills in the single digits and teens.
