Duluth, Minn. – Clear skies and calm winds could bring a frosty start to Memorial Day weekend across northeast Minnesota, with overnight lows dipping near freezing through early Friday.
According to the National Weather Service in Duluth, a Frost Advisory remains in effect tonight into Friday morning for much of northeast Minnesota and northwest Wisconsin. Temperatures are expected to fall between 32°F and 37°F, with the coldest pockets likely in low-lying rural areas.
Residents in Duluth, Ely, Hibbing, and Grand Marais should take precautions to protect sensitive plants and outdoor plumbing. Light frost formation is possible, especially under mostly clear skies overnight.
The days ahead will stay dry, with daytime highs ranging from the mid-50s to upper 60s through the weekend. Friday and Saturday will bring a mix of clouds and sun, while Sunday looks mostly sunny for most of the region. Overnight lows will gradually rise into the 40s by Sunday night, reducing frost risk.
No major rain is expected, though a few isolated sprinkles could develop in northeast Minnesota Friday or Saturday.
The Frost Advisory is set to expire by 8 a.m. Friday, but NWS officials say additional advisories could be issued if clear, calm conditions persist.
