Summery but windy today; much cooler on Labor Day

Rain in some areas on Monday

If you like summery temps and dew points, you’ll enjoy our Sunday weather. Highs are forecast to reach the 80s Sunday afternoon across roughly the southern half of Minnesota as well as western Wisconsin. The Twin Cities metro area will probably top out in the lower 80s, which is well above our average Sept. 6 high of 76. Most of northern Minnesota will have Sunday highs in the 70s.

Dew points will be in the 60s in locations that see highs in the 80s, so it’ll feel very summery.

Northeastern Minnesota and parts of western Wisconsin will have a chance of scattered showers and an isolated thunderstorm Sunday afternoon/early evening.

You can hear updated weather information on the MPR network, and you’ll see updated weather info on the MPR News live weather blog.

Winds will gust to 20-30 mph this Sunday afternoon/early evening in the Twin Cities metro area. Higher winds are expected to the north, and northwestern Minnesota could see gusts to 40-45 mph. There is a wind advisory from 1 p.m. to 8 p.m. this Sunday in much of northwestern Minnesota:

Chilly Labor Day

I’ve noticed some trees showing fall colors already. This tree in St. Paul has a nice selection of colors; including green, yellow, orange and red:
