Chicago, IL – A dangerous heatwave is set to strike Illinois midweek, with peak heat indices soaring to between 105°F and 115°F on Wednesday and Thursday. The combination of high temperatures and oppressive humidity will create unsafe conditions, especially in urban areas where minimal relief is expected at night.
According to the National Weather Service, the peak heat index for both days is expected to reach extreme levels, making outdoor activities hazardous. The heatwave follows several days of rain and storms, which will shift south of I-80 by Monday. The National Weather Service advises residents to take precautions and stay updated on the latest alerts.
In addition to staying hydrated and avoiding prolonged exposure to the sun, it is vital for residents to check that air conditioning units and fans are working properly, as there will be no significant cooling during the nighttime hours. Emergency cooling centers may be available, and people should know where to find them in case of power outages. If possible, limit outdoor activity, reschedule any strenuous activities, and check on vulnerable populations, including the elderly and those with pre-existing health conditions.
This extreme heat event may extend through Thursday, and while some relief could come with a cold front Friday, the timing of its arrival remains uncertain. Further updates are expected as conditions develop.
