Twin Cities Weather Update: Cool Nights in the 40s, Rain Moving In by Thursday Evening

A taste of autumn is settling in across Minnesota and Wisconsin, with cool nights, patchy frost, and rain chances increasing as we head into the weekend. The Twin Cities will experience chilly mornings and damp conditions, while northern Minnesota and Wisconsin may see temperatures cold enough for light frost.

Chilly Nights Across the Region

According to the National Weather Service in the Twin Cities, overnight lows are expected to drop into:

Mid-30s in northern cities like Duluth, International Falls, and Hayward

Low to mid-40s in the Twin Cities and southern Minnesota counties

In northern areas, the cold may be enough to trigger patchy frost, especially in rural valleys. Gardeners are advised to cover sensitive plants overnight to prevent damage.

Rain Likely Thursday Afternoon and Evening

Light showers may develop across southern Minnesota and western Wisconsin early Thursday morning, but the main round of rain is expected Thursday afternoon into the evening. A cold front pushing through the region will bring a stronger band of showers, especially in the evening hours.

Here’s what to expect:

Isolated showers early Thursday morning

Widespread rain Thursday afternoon and evening

Cool, damp conditions for commuters

Highs only in the low 60s

Drivers should be prepared for slick roads during the Thursday evening commute, especially in and around St. Paul and Minneapolis.

Continued Cool Weather Through the Weekend

Daytime temperatures will stay cooler than normal through the end of the week, with highs in the low 60s for Thursday through Saturday. Skies will remain mostly cloudy, and scattered showers are possible Friday and Saturday.

Warming is expected by Sunday, with partly sunny skies and temperatures climbing into the mid to upper 60s, and then near 71°F on Monday.
