Clouds are lingering Thursday but you will see some sun in the the coming days. A mix of sun and clouds is on tap for the holiday weekend.

We all know that the Memorial Day weekend can be summery or chilly. This will be one of those summery Memorial Day weekends.

Weekend temperatures and dew points

Our average Twin Cities high temperature is 73 degrees on May 28. Twin Cities metro area temps are forecast to reach the lower 80s this Saturday. High temps will reach the 80s in roughly the southern half of Minnesota on Saturday, with mainly 70s in northwestern Minnesota and western Wisconsin:

I say sticky with dew points in the 60s, but of course many people like the summery feel of those dew points in the 60s with temps in the 80s.

Memorial Day highs reach the 80s in many areas. Some spots in the Twin Cities metro area and to the south and east could top 90 degrees:

Northwestern Minnesota and areas near Lake Superior will see mainly 70s.

Thunderstorm chances

The atmosphere will be a bit unsettled this weekend, with scattered thunderstorms possible. In eastern Minnesota and western Wisconsin, thunderstorm chances look highest in the morning and in the evening/overnight hours each day.

Western Minnesota chances appear to be more evenly spread through the weekend. You can expect many more rain-free minutes than rainy minutes this weekend.

You can hear updated weather information for Minnesota and western Wisconsin on the Minnesota Public Radio News network, and you can see updated weather info on the MPR News live weather blog.

Severe weather outlook

The National Weather Service Storm Prediction Center shows a slight risk of severe weather (shaded yellow) Saturday and Saturday night in portions of west-central and southwestern Minnesota:

There’s a marginal risk of severe weather (shaded darker-green) across much of the remainder of Minnesota and into western Wisconsin.

Slight risk means that scattered severe thunderstorms are possible; marginal risk means that an isolated severe thunderstorm is possible:
