Minneapolis, MN – Parts of Minnesota could see their first frost of the fall Monday morning as temperatures drop into the 30s, followed quickly by a warmup into the 70s Tuesday.
According to the National Weather Service Twin Cities office, areas of frost are most likely across central Minnesota and western Wisconsin early Monday. Temperatures across the broader forecast area are expected to fall into the 30s and lower 40s.
The colder morning marks a familiar early October transition across Minnesota, when the first frost of the season becomes increasingly common. However, frost will not occur everywhere Monday, and the NWS specifically favors central Minnesota and western Wisconsin for the greatest coverage.
Sunday remains pleasant and considerably warmer. Mostly sunny skies are expected with highs from 65 to 70 degrees. Temperatures Sunday night will begin falling as winds become light, setting up favorable conditions for frost in colder locations by daybreak Monday.
Monday morning lows will range from 35 to 45 degrees. Patchy frost could affect gardens and other sensitive outdoor vegetation where temperatures fall into the middle 30s.
The chill will be short lived. Monday afternoon temperatures recover to between 65 and 70 degrees under mostly sunny skies.
A much warmer air mass arrives Tuesday. Highs are forecast to reach 75 to 80 degrees, with breezy conditions developing. Tuesday night lows should remain considerably milder, ranging from 50 to 55 degrees.
For the Twin Cities, temperatures may remain warmer than some outlying areas, while colder locations across central Minnesota have the better chance for frost. Residents with sensitive plants should check their local forecast Sunday night, with the frost risk peaking early Monday before a sharp warmup Tuesday.
