MILWAUKEE - The National Weather Service has now issued a heat advisory for Milwaukee, Waukesha, Racine, Kenosha, Washington, Ozaukee, and Fond du Lac Counties that goes into effect at 10:00 tomorrow morning and lasts until 9:00 tomorrow night.

An excessive heat warning remains in effect for Dodge, Jefferson, and Walworth Counties until 9:00 tomorrow night.

Today is our “brief relief” from the heat but you can barely call it that with dew points still in the 70s, it still feels warm and humid. 

Tonight will not give us any break from the warm and mugginess; temperatures will be in the low 70s.  There is a slight chance for a few showers and thunderstorms, but most of the activity will stay to our west, any storms that do creep into the area may bring heavy downpours and strong wind gusts. 

But not everyone will see rain tonight by any means.

Things get worse as we go into Wednesday with blazing sunshine temperatures will soar into the upper 90s, and the afternoon heat index could get close to 115° in some locations. 

The humidity will make it feel even warmer as dew points (measure of moisture in the air) stay in the mid to upper 70s, it will continue to be oppressively hot.  Wednesday will be the worst of this heat wave by far but there will be a stronger wind from the southwest at 10-20 mph.

Thursday will still be steamy and hot with temperatures only slightly cooler than Wednesday, highs will top out in the low 90s before a cold front makes its way through the area sparking off showers and thunderstorms that will eventually bring some cooler air into the forecast.  But we don’t completely shake the heat and humidity with that cold front, temperatures will slowly drop into the 80s as we finish out the work week and go into the weekend. 

Scattered showers and thunderstorms are possible from Friday through Sunday and that will help cool temperatures for next week when overnight low temperatures will finally be in the 60s and highs in the low 80s.
