A stretch of dry and pleasant weather is expected to continue across northeast Minnesota and northwest Wisconsin over the next few days, with cool nights and mornings giving way to mild afternoons.

Temperatures are expected to reach the 60s and 70s on Friday and Saturday, with highs primarily in the 70s on Sunday. Easterly winds on Friday will keep it slightly cooler near Lake Superior.

Most of the active weather through the middle of next week will focus on the western and eastern U.S., while an upper ridge over the upper Midwest will keep the weather quiet in that region.

Take a look at the fall color update as of September 25, 2025.
