Beautiful Saturday; thunderstorm chances ramp up on Sunday

Severe weather is possible Sunday afternoon and evening

Our Saturday weather might resemble that summery weather that you dreamt about in January.

Our average July 9 high temperature is 84 degrees in the Twin Cities. Many spots in the metro area will top out in the mid 80s Saturday afternoon. Most of Minnesota and western Wisconsin will see Saturday highs in the 80s, with some 70s in northeastern Minnesota.

Temperature trends

Highs will be in the upper 80s to around 90 across much of central and southern Minnesota on Sunday:

Looking ahead to next week, Twin Cities metro area highs are projected to reach the mid 80s on Monday, followed by lower 80s Tuesday. Metro area highs will return to the mid 80s Wednesday, then around 90 on Thursday and Friday.

Thunderstorm chances

A few scattered showers and thunderstorms are possible in northwestern Minnesota Saturday afternoon and evening. An isolated thunderstorm could develop in west-central and north-central Minnesota.

That shower and thunderstorm chance will spread eastward overnight Saturday night. The NWS Storm Prediction Center shows a slight risk (shaded yellow) of severe weather in far northwestern Minnesota Saturday and Saturday night:

Slight risk means that scattered severe thunderstorms are possible. An isolated severe thunderstorm is possible in the green-shaded area that’s labelled “1” on the map. Notes on timing and impacts are from the Grand Forks NWS office.

You can hear updated weather information for Minnesota and western Wisconsin on the Minnesota Public Radio News network, and you can see updated weather info on the MPR News live weather blog.

Sunday thunderstorm and severe weather outlook

A cold front moves slowly through Minnesota Sunday and Sunday evening, with plenty of warm, humid and unstable air out ahead of it. Minnesota and western Wisconsin could see a few scattered showers/t-storms Sunday morning. Then there will probably be a stronger batch of thunderstorms that spreads across much of the Minnesota and western Wisconsin Sunday afternoon and evening.  

Some severe weather is possible Sunday afternoon and evening. The NWS Storm Prediction Center shows a slight risk (shaded yellow) of severe weather Sunday and Sunday night for most of Minnesota and parts of west-central and northwestern Wisconsin:

Notes on thunderstorm timing and impacts are from the Twin Cities NWS office.

The Twin Cities metro area is included in that slight risk area, which indicates scattered severe t-storms are possible. The best chance of severe weather in the Twin Cities metro area would tend to be late Sunday afternoon and Sunday evening. Check forecast updates.
