Expect another very comfortable September day on Friday with highs staying in the 70s with low humidity. The start of the weekend on Saturday will be a lot different. Expect the humidity to ramp up with dew points Saturday rising into the upper 60s making it feel very humid. The humidity will stay noticeable on Sunday and you'll likely notice it through the middle of next week.
Both Friday and Saturday look to continue our dry stretch of weather in Wisconsin. Saturday night and most of Sunday does have the possibility for a few showers. The activity looks pretty light so you probably don't need to change plans but you might want to grab the umbrella. The rain could linger into Monday morning but Monday afternoon right now looks dry. If you're looking for a soaking rain the best chance for that is Tuesday.
Overall a 50/50 weekend with the summer heat on Saturday and the light showers on Sunday.
