Marquette, Michigan – Residents across Michigan’s western Upper Peninsula should brace for a sudden drop in temperatures overnight, with frost expected to settle in by early Sunday morning.
According to the National Weather Service in Marquette, a Frost Advisory is in effect from 1 a.m. to 9 a.m. EDT Sunday, with lows near 32°F forecast across Baraga, Delta, Dickinson, Gogebic, Houghton, Iron, Marquette, and Ontonagon counties.
Cold-sensitive plants and early-season gardens may be at risk, especially in rural and low-lying areas such as Kenton, Gwinn, and Iron Mountain. Homeowners are urged to cover flowers, move potted plants indoors, or use frost cloths to minimize damage.
Roads are not expected to be icy, but the unseasonable chill could impact outdoor Memorial Day weekend plans, especially early Sunday. This marks one of the latest frost advisories of the season for this region, which typically warms by late May.
Temperatures are expected to rebound by mid-morning Sunday, but additional advisories remain possible depending on cloud cover and wind conditions. Stay updated through local alerts and prepare now to protect vulnerable plants tonight.
