Davenport, IA – Dangerous heat is expected to settle over parts of eastern Iowa and northwestern Illinois beginning Wednesday, with the National Weather Service warning that heat index values could climb as high as 105 degrees during the afternoon.
According to the National Weather Service Quad Cities office, a Heat Advisory is in effect from noon to 8 p.m. CDT Wednesday for portions of northeast Iowa and far northwest Illinois. Afternoon temperatures are expected to reach the low to mid-90s, while high humidity will make it feel significantly hotter.
Forecasters expect peak heat index values between 100 and 105 degrees, creating conditions that increase the risk of heat-related illnesses, particularly for those spending extended time outdoors.
Communities included in the advisory include areas around Dubuque, Maquoketa, Freeport, and surrounding portions of northeast Iowa and northwest Illinois.
The National Weather Service also says the hot and humid pattern will continue through the remainder of the workweek and into the weekend. Daily heat index values between 95 and 100 degrees are expected from Thursday through Saturday, with some locations potentially exceeding those values during the hottest part of the afternoon.
Officials urge residents to stay hydrated, limit strenuous outdoor activities during peak heating hours, and take frequent breaks in air-conditioned or shaded locations. People working outdoors should schedule frequent rest periods, while residents are encouraged to check on older adults, young children, and others who may be more vulnerable to the heat.
The Weather Service also reminds drivers to never leave children or pets unattended in a parked vehicle, where temperatures can become life-threatening within minutes.
Residents should continue monitoring the latest forecasts, as additional heat advisories or warnings may be issued if dangerous conditions persist.
