Your formal introduction to summer is on the way this week as warmer temperatures arrive in northeast Wisconsin.

While the lake will keep the Door Peninsula in the mid- to upper 70s, the National Weather Service is forecasting that parts of Kewaunee and Brown counties could see temperatures reach the low 90s, with the heat index making it feel even warmer.

While Brown County reached 90 degrees in late May, Door and Kewaunee counties have not seen 90-degree temperatures since last August.

Kewaunee County Public Health Director Cindy Kinnard says that, in addition to staying in the shade, avoiding strenuous activities during the hottest parts of the day and wearing loose-fitting clothing, one of the best ways to beat the heat is by paying attention to what you drink and eat.

The midweek warm spell will be accompanied by summer storms that could bring temperatures back into a more comfortable range by the end of the week.
