and last updated

Let's soak up this comfort while we have it. It has been an absolutely beautiful day with sunshine and temperatures in the 70s. It's going to be another comfortable evening on the Summerfest grounds, but with a chance of a little bit of Lake fog forming at times. Lows tonight will be around 60 degrees.

Sunday should still be pretty nice and a little bit warmer. A few showers may pop up Sunday afternoon and evening as a warm front passes through. This warm front brings extreme heat next week. This will likely be an official heatwave with several days in the 90s, along with triple-digit heat index values.

WATCH: Will we be seeing a heatwave this week?
