A view from above

This satellite loop, which runs from about 2 p.m. to early this evening, shows thunderstorms erupting over southern Minnesota and western Wisconsin:

The thunderstorms brought a rush of cooler air as they moved through.

Warm Saturday

High temperatures on Saturday will be 10 to 15 degrees above normal over much of Minnesota:

rt611h3

It will be slightly less humid, but many spots in southern Minnesota will have dew point temperatures in the 60s.

Chance t-storms Sunday

Scattered thunderstorms are possible on Sunday, and more widespread showers and thunderstorms could move through Sunday evening.

Here is the forecast rainfall pattern, from this afternoon through Sunday evening, from the National Oceanic and Atmospheric Administration’s North American Mesoscale Forecast System:

NOAA/NAM data, via College of DuPage

You'll notice the thunderstorms that develop Sunday and Sunday evening, toward the end of the sequence.

The Storm Prediction Center of the National Weather Service indicates a marginal risk of severe weather over Minnesota and Wisconsin Sunday and Sunday night:

Cooler temps in sight

Highs on Sunday will be a bit cooler in many spots:

rt612h3

Southwestern Minnesota will still be in the 90s.

80s will be common on Monday over southern Minnesota, but we could see mostly 70s on Tuesday and Wednesday.

I hope you have a good weekend!
