Seasonable temperatures as fall begins Wednesday
Minnesota could see areas of frost the final morning of summer
Sunshine dominates the forecast most days through the weekend as Minnesota officially turns the corner from summer into fall.
Tuesday’s Forecast
The storm system that brought Minnesota showers and thunderstorms Monday has continued its trek eastward, and now high pressure is building in.
That has returned clear skies across the state, and with a continued northerly flow behind Monday’s cold front, most of the state started Tuesday in the 40s, with a few low 50s.
Breezy northwest winds continue during the day, keeping highs slightly below average, with almost the entire state in the 60s under mostly sunny skies.

Extended forecast
Given the cool temperatures Tuesday and continued clear skies overnight, Wednesday will start even chillier for most of Minnesota, with even more spots in the 40s.
Most of the Arrowhead is expected to drop into the 30s, leading to a frost advisory for that area from 1 a.m. to 8 a.m. Wednesday morning.
Temperatures rebound quickly during the day though, with highs making it into the upper 60s, with a few 70s west, under sunny skies. Autumn begins at 2:20 p.m. Wednesday in Minnesota.
A few more spots see the low 70s Thursday, before a cold front brings back cooler 50s north and low 60s south on Friday.
Here is that temperature trend for the Twin Cities:
The same system that cools temperatures Friday also provides the next rain prospect for Minnesota.
However, precipitation is currently forecast to be predominantly light and spotty, with the best rain chances north, and most places seeing less than one-quarter inch.
After that rain clears out early Saturday, the rest of the weekend is likely to stay dry, with highs in the 60s and 70s.
