It was nearly perfect today! While temperatures topped out a couple degrees below average, there was plenty of sunshine so it still felt warm. In addition, the wind was light and humidity was low. Dew points ranged from the upper 40s to mid 50s this afternoon, well below where most people feel humidity.
This, unfortunately, will not be a trend.
Dew points increase overnight to near 60 by morning then keep going up during the day, perhaps as high as the mid 60s. A weak front will push through, but chances for thunderstorms are low along it despite the increased humidity. Many places may stay dry due to isolated nature of shower and storm activity. Still, any storm that forms will have the ability to become stronger. As such, there is a risk for isolated strong to severe thunderstorms.
Once those pass, dew points will drop to near 60 for Saturday. This is still a little humid, but not too bad for the middle of summer. It’ll be sunny and warm, too, with highs in the middle 80s.
Heat and humidity increase for Sunday and remain high much of next week.
Expect highs near 90, lows near 70, and high humidity along with slight chances for pop up showers and thunderstorms each afternoon. Chances for showers and storms increase a little Wednesday and Thursday, and more hot and humid air builds back into Wisconsin for next weekend.
