Brace yourselves. We're in for excessively hot weather that will break the 100-degree threshold through the end of the week.
The National Weather Service (NWS) has issued an excessive heat watch and a heat advisory for the Chicago area Through Thursday evening. The heat advisory is through 7 a.m. Wednesday, while the excessive heat watch remains in effect through Thursday evening.
On Wednesday and Thursday, temperatures are expected to reach or surpass 100 degrees with a low near 80 degrees. Heat indices are likely to peak near 105 degrees and may reach 110 on Thursday.
There's also a 30 percent chance that thunderstorms may make their way into the area late Wednesday and possibly into Thursday, according to the NWS. "If this does not occur, then an excessive heat warning would likely be needed Thursday and Friday," said the NWS.
The National Weather Service suggests residents take the following precautionary actions:
- If you work or spend time outside, when possible, reschedule strenuous activities to early morning or evening.
- Know the signs and symptoms of heat exhaustion and heat stroke.
- Wear lightweight and loose-fitting clothing when possible
- Stay hydrated and drink plenty of water.
- Stay out of the sun
- Check up on relatives and neighbors
- Don't leave children and pets unattended in vehicles under any circumstances.
To reduce the risk of heat-related conditions, the Occupational Safety and Health Administration suggests scheduling frequent rest breaks in air-conditioned or shaded areas. If anyone is overcome by heat, they should be moved to a cool and shaded area. If someone falls to heat stroke, call 9-1-1.
