We're in for excessively hot weather through the end of the week that will break the 100-degree threshold. The same heat wave which created a record-breaking Fourth of July will continue in Frankfort through 7 p.m. Saturday, July 7, according to reports.

The National Weather Service (NWS) has issued an excessive heat warning for the Chicago area, including Frankfort, in effect through that time.

On Thursday, highs will top out between 100 and 105, with nighttime lows dropping into the 80s.

Peak afternoon heat index readings through Friday are likely to range from 105 to possibly as high as 115 degrees, according to the NWS. Oppressive heat and humidity will continue during the nighttime hours where the heat index will spend most of the night hovering in the 90s.

The Will County Health Department is asking residents to be careful and take precautions when it comes to the extreme heat and humidity.

Throughout the Lincoln-Way area, cooling centers will be available for residents as a way to avoid these potentially hazardous conditions. Here's a list of centers in the area:

Tips to Cope With the Heat

The Will County Health Department is also warning residents that infants, seniors and chronically ill residents are at a greater risk during this extreme heat. The department also offers these tips to cope with the weather.

1. Drink plenty of water and natural juices, while avoiding alcoholic and caffeinated beverages, which can tax the circulatory system during times of high heat and humidity.
2. Limit exercise and avoiding working during the hottest hours (usually from 10 a.m. to 3 p.m.). Make sure to drink two to four glasses of water, natural juices or sports beverages, which can replace the salt and minerals you lose through sweat.
3. Wear a wide-brimmed hat, sunglasses and sunscreen if you're out during the hottest hours. Sunscreen should have an SPF rating of 15 or higher.
4. Wear loose, lightweight, light-colored clothing. Cotton clothing is usually the best.
5. Don't eat heavy meals. Several small, light meals are best. Try not to use the oven and other appliances that generate a lot of heat.
6. Don't let anyone sit in a hot car, even for a few minutes. Temperatures can reach extremely dangerous levels in minutes.
7. If you don't have air-conditioning, draw the shades and keep your blinds closed. Open your windows slightly for any breeze.
8. Electric fans won't prevent heat-related illness when temperatures approach triple digits. Showers or baths can help with heat-related stress.
