Weekend forecast: Summery 80s; scattered late Sunday showers

Dew points in the sticky 60s

We can’t rule out an isolated shower or thundershower in the Twin Cities metro area Friday afternoon and early Friday evening, but the better chance of showers and thunderstorms will be in southeastern Minnesota and west-central Wisconsin plus southern Wisconsin.

The National Weather Service Storm Prediction Center shows a slight risk of severe weather this afternoon and evening (shaded yellow) in a couple of counties in far southeastern Minnesota and into southern Wisconsin, with an enhanced risk of severe weather in far southern Wisconsin:

The area shaded in dark green in the remainder of southeastern Minnesota and parts of western Wisconsin has a marginal risk of severe weather Friday afternoon and evening, which means that an isolated severe thunderstorm is possible.

Now let’s talk about the weekend!

Warm and a bit humid

Our average Twin Cities high temperature on June 27 is 82 degrees. We’ll probably reach the upper 80s in the Twin Cities metro area Saturday afternoon. Most of Minnesota and western Wisconsin will have highs in the 80s on Saturday:
