Twin Cities cools slightly for weekend; poor air quality lingers in northeastern Minnesota

Slightly cooler conditions are in store for the Twin Cities on Saturday and Sunday. Further north, poor air quality will remain a concern through the weekend.

High temperatures across the metro will be near 90 degrees on Saturday and Sunday, with lows near 70. 

An air quality alert remains in place until 11 a.m. Monday for the Arrowhead, where the air is still hazardously polluted.

Wildfire smoke returns to Wisconsin on Saturday and it may impact the Twin Cities on Sunday.

Temperatures on Monday will be around 90 degrees. Thunderstorms are likely and there's a potential for severe weather.

Tuesday and Wednesday will be cooler with temperatures in the 80s, though wind gusts could hinder wildfire control efforts up north.

There will be a gradual warming trend late next week with sunshine and drier conditions.
