Marquette, Mich. – Gardeners and growers across Michigan’s Upper Peninsula should brace for a sharp drop in temperatures overnight, with a frost advisory in effect from midnight to 9 a.m. EDT Sunday.
According to the National Weather Service in Marquette, temperatures could fall as low as 28°F in counties stretching from Keweenaw and Ontonagon to Marquette, Luce, and Menominee. The advisory warns that exposed plants and garden crops may suffer damage or be killed if left unprotected.
Cities including Houghton, Ironwood, Escanaba, Newberry, and Gladstone are all at risk as clear skies and calm winds set the stage for frost to settle early Sunday morning. Homeowners are urged to cover any sensitive plants tonight or bring them indoors if possible.
This late-season cold snap is unusual but not unheard of for the region. It comes just days after warmer temperatures lured many residents into planting early summer vegetables and flowers.
The frost advisory remains in effect until 9 a.m. EDT Sunday. Further alerts are not expected, but residents should stay tuned in case additional advisories are issued if colder pockets persist into Monday.
