A cool and windy Saturday; some river levels near peak this weekend

Don't bother combing your hair before you head outside today; the brisk winds will muss it up.

Temps will be cool, but at least the sun will shine for the bulk of the day.

Temperature trends

Minnesota and western Wisconsin highs will be mainly in the 30s this Saturday afternoon, but a few spots in the Twin Cities metro area and far southern Minnesota could touch 40 degrees or so. Our average high this time of year is 49 degrees in the metro area.

Sunday highs are expected to be in the 30s across northern Minnesota, with mainly 40s central and south. Parts of southwestern Minnesota could touch 50 degrees:

Twin Cities metro area highs are projected to reach around 50 on Monday, followed by lower 50s Tuesday, 50 Wednesday, mid 40s Thursday and lower 50s on Friday

Rain and snow chances

Here's a look at rain/snow chances over the next few days:

  • Some snow showers are expected to move into northwestern Minnesota early Sunday, then spread southeastward. They would tend to mix with rain showers then change to scattered rain showers or sprinkles by Sunday afternoon.

  • Southwestern Minnesota could see some rain/snow showers late Monday.

  • Tuesday into early Wednesday look dry for most of Minnesota, but rain showers could move into southern Minnesota Wednesday afternoon and linger into Thursday.

The National Oceanic and Atmospheric Administration’s Global Forecast System model shows the potential precipitation pattern Wednesday through Thursday:

The color chart to the right of the loop refers to the precipitation rate (mm per hour), not to the total amount of rain or snow.

We'll see if the forecast models shift the precipitation as we get closer to Wednesday. As always, updated weather information can be heard on the Minnesota Public Radio Network, and you’ll also see updated weather info on the MPR News live weather blog.
