Showers, thunderstorms possible Friday and Saturday

I can’t think of any part of Minnesota that needs rain right now.

Northern Minnesota has received ample summer rains, and many spots in central and southern Minnesota are waterlogged.

Parts of southern Minnesota, southward from far southern Dakota County, are under a flood warning until 8 a.m. Saturday:

Thunderstorm chances

Scattered showers, and a few isolated thunderstorms, could develop over Minnesota today.

More widespread showers and thunderstorms are possible late Saturday afternoon into Saturday night as a warm front pushes north:

The National Oceanic and Atmospheric Administration’s North American Mesoscale 4 km resolution forecast model shows the general rain pattern today through Sunday morning:

There is a potential for some strong to severe thunderstorms late Saturday afternoon into Saturday evening.

The Storm Prediction Center of the National Weather Service shows a marginal risk of severe weather Saturday through Saturday night over much of central and southern Minnesota:

Storm Prediction Center/National Weather Service

A marginal risk means that an isolated severe thunderstorm is possible.

Warmer Saturday

Highs could pop into the lower 80s over southwestern Minnesota tomorrow, with 70s common elsewhere:

Many spots in the Twin Cities will see upper 70s, maybe even an 80 on a few unofficial bank thermometers.

60s will linger over northeastern Minnesota.

A cold front sweeps through early on Sunday, so highs in the 60s will be common:

The Twin Cities will have highs in the low to mid 60s Monday and Tuesday, then around 70 Wednesday.

Fall colors

The latest Minnesota fall color report from the Minnesota Department of Natural Resources shows some areas of very good fall color over northern Minnesota right now:

A Wisconsin fall color report is also available.
