Hot and humid conditions are expected through the afternoon and early evening, with peak heat indices in the mid 90s to around 100 degrees. If you plan to be outside, avoid strenuous activity and prolonged exposure to the heat by taking breaks in the shade or in an air conditioned building, and drink plenty of water to avoid dehydration.
The Illinois Environmental Protection Agency has issued an Areawide Air Pollution Action Day for Sunday July 19th for portions of Illinois.
An Areawide Air Pollution Action Day is declared when weather conditions are such that widespread ozone and or particulate levels are forecast to be at OR ABOVE the Unhealthy for Sensitive Groups (USG) category in all or nearly all Illinois AQI forecast sectors.
Areas both inside and outside of the Action Day coverage area may experience smoke/PM2.5 to a varying degree and duration both later today and Sunday. Those with air quality concerns or anyone in Illinois with outdoor plans is encouraged to check current NowCast readings or sign up for EnviroFlash alerts on AirNow.gov. Before going outside, checking the NowCast AQI will help identify periods of both poor and cleaner air quality regardless of the level of the daily forecasted AQI.
