Door and Kewaunee counties may be outside the heat advisory zone other parts of northeast Wisconsin are facing, but you will still likely face some of the warmest summer weather to kick off this week. Nearby Oconto, Brown, and Calumet counties are all under a heat advisory from 1 p.m. until 7 p.m. on Monday, thanks to a high temperature of 90 degrees and a heat index of between 100 and 105. It will be even hotter in central and western Wisconsin, where heat indices could reach as high as 114. It will not feel warm in Door and Kewaunee counties, where it is expected to have a heat index of 89 in Sturgeon Bay and 80 on Washington Island. Door County Public officials still remind you to drink plenty of fluids, stay away from strenuous activities, and wear loose-fitting clothing to stay cool.

The heat wave will be relatively short-lived, with high temperatures returning to the 70s on Wednesday. You’re also reminded not to leave your pets or children inside your vehicle for long periods. Even when the outside temperature is 70 degrees, it could reach nearly 90 degrees after 10 minutes and over 100 degrees in 30 minutes.
