Heat wave likely to persist through July

Hotter and drier than average conditions likely through next week.

The hot (and smoky) weather hits just keep on coming in the steamy summer of ‘21.

We may see less wildfire smoke over Minnesota through Friday. But that means more solar radiation reaching the ground to heat up our already steamy air mass.

Highs Thursday will push past 90 degrees once again in much of Minnesota.

We’re already past the annual average number of 90-degree days in Minnesota. We’ll likely add another seven to 10 days of 90-degree heat through the rest of July.
