Marquette, MI – A late-August cold snap will bring frost concerns across parts of Michigan’s Upper Peninsula, northern Wisconsin, and northwestern Wisconsin early Friday morning.
According to the National Weather Service in Marquette, a Frost Advisory remains in effect from 2 a.m. to 9 a.m. EDT Friday for Baraga, Iron, Gogebic, Ontonagon, and Southern Houghton Counties. Temperatures could fall as low as 29 degrees, leading to widespread frost formation.
The National Weather Service in Green Bay has also issued frost advisories for several northern Wisconsin counties. Vilas County is under an advisory from 1 a.m. to 8 a.m. CDT Friday, with temperatures expected to dip between 33 and 37 degrees. Additional advisories cover Lincoln, Oneida, Florence, and Forest Counties during the same time frame.
Further west, the National Weather Service in Duluth reported that Ashland and Iron Counties, including the Bad River Reservation, Lac du Flambeau Band lands, and Madeline Island, will also be under a Frost Advisory from 1 a.m. to 8 a.m. CDT Friday.
Officials warn that the cold temperatures may damage or kill sensitive outdoor vegetation if not properly protected. Gardeners and homeowners are urged to cover tender plants or bring them indoors to prevent frost damage.
The advisories highlight a quick shift into fall-like weather, a reminder for residents to prepare for colder overnight conditions that often arrive early across northern Wisconsin and Michigan’s Upper Peninsula.
