Duluth, Minnesota – Spotty frost could develop tonight across the Northland before rain returns late Wednesday night and temperatures climb toward 70 by Friday.
According to the National Weather Service in Duluth, mostly sunny skies will dominate Tuesday, with temperatures ranging from 56 to 64 degrees. Winds will ease across much of the Northland, although breezy conditions will persist in the Twin Ports near Lake Superior.
Another chilly night follows, bringing one more opportunity for spotty frost before overnight temperatures begin a warming trend. Residents with frost sensitive plants may want to protect them overnight where temperatures fall sufficiently.
Wednesday remains sunny, with highs ranging from 57 to 66 degrees. Rain chances then return late Wednesday night into Thursday morning, mainly across north central Minnesota.
Thursday temperatures range from 57 to 67. The Weather Service graphic indicates morning rain chances before conditions improve during the day.
By Friday, the warming trend becomes more noticeable. Highs across the region are expected to reach 62 to 70 degrees, bringing parts of the Northland close to 70 after Tuesday's much cooler conditions.
Another opportunity for rain is expected over the weekend, though the supplied Weather Service information does not provide specific timing or rainfall amounts. Residents should watch for updated details as the weekend approaches.
The immediate concern is tonight's potential frost, followed by rain returning to parts of northern Minnesota late Wednesday night and Thursday morning.
