A frost advisory has been issued for Livingston, Washtenaw, Oakland, Macomb, Lapeer, St. Clair and Sanilac counties from midnight through 9 a.m. Friday. 

It won't be quite as chilly Thursday night as it was Wednesday night, but overnight temperatures are expected to drop into the mid-30s, increasing the potential for frost to develop. We are expecting high clouds to increase through the overnight hours, but they won't be fully over the area until closer to sunrise, increasing the chance of chillier overnight low temperatures. 

Wayne and Monroe counties are not included in the advisory; however, some areas will see low temperatures in the upper 30s.

Sensitive plants should be covered before sunset to conserve heat. Expect a chilly start to your Friday.
