It's been an fantastic week of summer weather across southeast Wisconsin with plenty of sunshine and comfortable levels of humidity. However, you'll notice an uptick in humidity throughout the weekend, with pretty muggy air expected on Sunday. 

That's when we'll have the best chance for showers and storms this weekend, however they will be pretty hit or miss. A few isolated showers or storms will be possible after sunset Saturday night, with the best chance far north or west of the Milwaukee Metro. As a weak front moves closer on Sunday, more spotty showers and storms will be possible, but they're not a guarantee for all. 

Not only will the humidity be building back in, but so will the heat. Highs in the mid to upper 80s are expected throughout the weekend with upper 80s to low 90s possible through the first half of next week.

Although we've had plenty of heat this summer, Milwaukee has only had 5 days in the 90s this year.

Sunday marks the average date for the last 90 degree day in Milwaukee, but reaching the 90s in September isn't uncommon. Milwaukee's last 90 degree day of the year has occurred in September 4 of the last 5 years.

The heat and humidity won't last through all of next week. Download the CBS 58 Ready Weather App to see when temps will drop closer to normal.
