Shower and thunderstorm chances Sunday; dry to the north on Labor Day

Our Saturday high temp was 88 degrees at Minneapolis-St. Paul International Airport.

It felt more like July 1 than September 1.

It was our warmest official Twin Cities high temp since August 16, and the dew point temp of 70 degrees added a bit of a steamy feeling to the afternoon.

Temperature trends

Cooler high temps are expected on Sunday, with 70s across most of Minnesota:

The Twin Cities and a few other spots to the south could touch 80.

Labor Day will feature a lot of highs in the 70s, and there could even be a few upper 60s near Lake Superior:

Twin Cities metro area highs are projected to reach the upper 70s on Tuesday, followed by low to mid 70s Wednesday through Friday.

Our average high temp is 77 degrees in the Twin Cities metro area during the first few days of September.

Thunder chances

Scattered showers and thunderstorms are expected to spread into Minnesota during the overnight hours of Saturday night.

Some periods of showers and thunderstorms are expected across most of Minnesota on Sunday and Sunday evening.

Updated weather information can be heard on the Minnesota Public Radio Network, and updates are also posted on the MPR News live weather blog.

The National Oceanic and Atmospheric Administration’s North American Mesoscale forecast model shows the potential rain pattern Sunday through Sunday evening:

It will probably rain in some areas that look rain-free in the loop, but the general rainfall pattern is illustrated.

The color chart to the right of the loop refers to the strength of the signal that returns to the radar, not to the amount of rain.

The Storm Prediction Center of the National Weather Service shows a marginal risk of severe weather for parts of far southeastern Minnesota Sunday and Sunday night:

Marginal risk means that an isolated severe thunderstorm is possible.

On Labor Day, roughly the southern half of Minnesota will have a chance of scattered showers and thunderstorms.
