Some 70s on Monday, then cooler; wet September

The southern half of Minnesota had weather perfection this weekend, with plenty of sunshine and comfortable temperatures.

Our Sunday afternoon high of 76 degrees at Minneapolis-St. Paul International Airport was 7 degrees warmer than our average Twin Cities high temp for this time of year.

Where do we go from here?

Temperature trends 

We’re expecting Monday afternoon highs in the 70s from the Twin Cities metro area into southeastern Minnesota:

Northwestern Minnesota will only reach the 50s.

The 50s will linger over northern Minnesota on Tuesday, with lower 60s in the south.

Twin Cities metro area highs are projected to be in the lower 60s Tuesday and Wednesday, then around 60 on Thursday and Friday.

There aren’t any really warm temperatures in sight.

The September 29 through October 3 temperature outlook from the NWS Climate Prediction Center shows a strong  tendency for cooler than normal temperatures in Minnesota:

Rain chances

Western Minnesota has the best chance of showers Monday morning, then showers and a few thunderstorms are expected to spread eastward Monday afternoon and evening.

Updated weather information can be heard on the Minnesota Public Radio Network, and you can see updated weather info on the MPR news live weather blog.

The Twin Cities metro might not see a shower/isolated t-storm until mid to late afternoon on Monday, with scattered showers/thunderstorms possible Monday evening. There will be a chance of scattered showers on Tuesday.

The National Oceanic and Atmospheric Administration’s North American Mesoscale forecast model shows the potential rain pattern Monday morning through Tuesday afternoon:

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.

Wet September

Our average rainfall for the entire month of September is 3.08 inches in the Twin Cities.

As of Sunday morning, the September rainfall total at Minneapolis-St. Paul International Airport was 6.50 inches:

We didn’t add a drop of rain to our September total on Sunday.

We’ve already received more than twice our average September rainfall in the Twin Cities, and we still have one week remaining in the month.

That’s wet!
