Severe weather possible in some areas Saturday night; Sunday rain chances highest north

Fall color update for leaf-peepers

The Saturday high temperature at Minneapolis-St. Paul International Airport was 79 degrees. That’s warm for Oct. 9; our average Twin Cities high is just 62 degrees this time of year.

Along with the warmth, we had sticky dew points here and across most of Minnesota. That moisture will provide fuel for thunderstorms.

Minnesota and western Wisconsin will see areas of showers and thunderstorms Saturday evening and overnight Saturday night.

The NWS Storm Prediction Center has included three west-central Minnesota counties in a severe thunderstorm watch that continues until 10 p.m. this Saturday:

“Tonight” in the NWS graphic refers to Saturday evening and overnight Saturday night. The dark-green shaded area, which includes the Twin Cities, has a marginal risk of severe weather; meaning that an isolated severe thunderstorm is possible.
