Weekend forecast: Steamier, with thunderstorm chances

Many rain-free hours too

While running errands this morning, I heard someone say “this feels like fall.” Our weekend weather should convince most of us that summer isn’t over.

Saturday highs will be in the 80s, and a few spots in far southern Minnesota could be close to 90 degrees:

Thunderstorm chances

Clusters of thunderstorms are expected to move across Minnesota and western Wisconsin from Friday evening into early Saturday.

The National Oceanic and Atmospheric Administration’s North American Mesoscale (NAM) forecast model shows the potential rain pattern Friday evening through Saturday morning:

Thunderstorms may redevelop Saturday night into early Sunday.

At this point it looks like northern Minnesota and northwestern Wisconsin will have the best chance of scattered thunderstorms Sunday afternoon, with a smaller thunderstorm chance in the south.

Scattered thunderstorms will be possible in all areas Sunday evening and Sunday night.
