The storm track stays north all week, so the best thunderstorm chances will be around Chicago on into Indiana. We still have a slim chance to see a spot storm or two throughout the week. Our best chances to see rain and thunderstorms will be Friday into early Saturday. Our weekend temperatures should cool down a bit, into the 80s to around Saturday and Sunday as the heat and humidity ease a bit.
Remember, high heat coupled with high humidity increases the risk for heat-related illness.
Limit your time outdoors during the hottest time of day. Wear loose, light-colored clothing and try to get into the air conditioning as often as possible. Drink plenty of water. Keep pets inside during heat like this and remember to check on elderly family and friends along with your children.
The first sign of many heat-related illnesses starts with the sweat glands. If you're outside this week and not sweating, that could be your first sign that you may be getting overheated and/or dehydrated.
