A nice Sunday, with no steamy weather in sight; flooding update

I’m hearing a lot of positive comments about our current weather pattern.

We can enjoy our outdoor activities without steamy weather!

Sunday will be another keeper.

Temperature trends 

Many spots in Minnesota will see highs in the lower 80s Sunday afternoon:

The northeast will have cooler 70s.

We’ll have highs in the 70s north and lower 80s south on Monday:

Our Twin Cities metro area highs will be around 84 degrees on Tuesday, followed by 81 Wednesday and upper 70s Thursday and Friday.

Rain chances

Parts of northeastern Minnesota could see scattered showers and even an isolated thunderstorm this Saturday evening.

Scattered showers and thunderstorms could move into northwestern Minnesota Sunday evening, then spread to the east-southeast Sunday night and Monday.

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

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.

Minnesota will have a chance of scattered showers and an isolated thunderstorm late Tuesday night and Wednesday.

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

Flooding update

Some rivers in southern Minnesota are still above flood stage due to several bouts of heavy rain in June and July.

The Twin Cities office of the NWS has areas with flood warnings shaded green on their main page:

Here’s the Saturday morning flood update from the NWS:

Runoff from recent heavy rainfall has led to both the Cottonwood

rainfall is expected through Sunday, so the rivers will likely
begin to fall over the next 24 to 36 hours.
