A warm and sunny start to autumn

Smoke brings more haze and impacts air quality

Fall starts Tuesday morning, but the day will feel more like summer with abundant sunshine and warm weather.

Tuesday’s forecast

Because of clear skies and mostly calm winds overnight, northern Minnesota is starting off chiller than Monday, with more 40s and a few 30s, but this is closer to average for late September. Southern Minnesota is beginning the day with 50s and 60s. 

The entire state warms to about 10 degrees or more above average by the afternoon, with 70s north and 80s in southern and central Minnesota.

Combined with widespread sunshine, it will feel very summerlike, despite fall officially beginning at 8:30 a.m. Tuesday. 

The sunshine will be hazy again, especially for the southern half of Minnesota, due to smoke from the West Coast fires making it into our atmosphere again.

Parts of southern Minnesota can also expected the air quality to be in the “moderate” category at times as some of the smoke filters to the surface.

The rest of the week stays mild, with a couple chances for needed rain. That extended forecast will be updated around 9 a.m.
