The FOX6 Weather Experts said highs on Tuesday will reach the low 90s yet again and could feel between 100-108 at times. Dew points will drop slightly into the upper 60s on Wednesday, but rise again Wednesday night into Thursday as another warm front will lift over southeast Wisconsin. 

Dew points will finally drop heading into Friday afternoon and evening and will continue to do so over the weekend as more comfortable air returns. For the mean time, plan on taking it easy and not to over exert yourself. With the high heat indices in store, this calls for dangerous heat if you are outside for extended periods of time.  


With the high heat and humidity on Tuesday, there is a risk for thunderstorms, especially in the afternoon and evening.  Strong to severe storms are possible with the main threats being damaging winds, large hail, and torrential rainfall.
