Milder temperatures return, with afternoon/evening thunderstorm chances

An isolated severe thunderstorm is possible Saturday and Saturday night

Friday felt like late October. Today will feel like September, and Sunday will feel a bit like August in some locations. Don’t you love our changeable weather?

Temperature trends

Saturday afternoon highs will range from the lower 80s in parts of southwestern Minnesota to the 60s in north-central and northeastern Minnesota. There will be a lot of 70s in between, with mid 70s possible in the Twin Cities metro area.

Sunday highs feature mostly 70s in northern and central Minnesota, with some 80s in the far south:

Rain and thunder chances

Some showers are expected to spread across parts of far northern Minnesota as we go through Saturday afternoon and evening. West-central Minnesota looks dry today, but the remainder of central and southern Minnesota, plus western Wisconsin, will have a chance of scattered showers and thunderstorms as we go through Saturday afternoon and evening.

An isolated severe thunderstorm is possible. The National Weather Service Storm Prediction Center shows a marginal risk of severe weather Saturday and Saturday night for portions of Minnesota, including the Twin Cities metro area, and west-central Wisconsin. Here is the Twin Cities NWS discussion of the marginal severe risk in the dark-green shaded area:

The ground is saturated in many parts of southern Minnesota, and additional rain could cause flash flooding in some areas. The National Weather Service has issued a flash flood watch from 7 p.m. this Saturday to 7 a.m. Sunday for parts of southeastern Minnesota. The watch includes Dodge, Olmsted, Mower, Fillmore, and Houston counties. Rochester and Austin are a couple of cities in the flash flood watch.

It’s very early in our fall color season. Our beautiful fall colors should really start to dazzle in two to three weeks.
