Davenport, Iowa – A wave of extreme heat is set to grip eastern Iowa and western Illinois on Friday, with the National Weather Service (NWS) issuing a Heat Advisory from 1 to 7 p.m. Forecasters warn that heat index values could reach as high as 105 degrees, creating dangerous conditions for anyone exposed to the heat for long periods.
The advisory covers major cities including Davenport, Cedar Rapids, Iowa City, Moline, and Rock Island, along with smaller towns across the region. The combination of soaring temperatures and high humidity will make it feel even hotter, increasing the risk of heat-related illnesses such as heat exhaustion and heat stroke.
Health officials are urging residents to stay hydrated, avoid strenuous activities during the afternoon, and seek air-conditioned spaces whenever possible. Vulnerable groups, including seniors, young children, and those without access to reliable cooling, should be checked on regularly to ensure their safety.
Outdoor workers, road crews, and anyone with afternoon plans outside are advised to take frequent breaks, wear light and loose clothing, and watch closely for warning signs of heat stress—such as dizziness, nausea, or rapid heartbeat. Local cooling centers and public buildings are available for those in need of relief from the oppressive heat.
While the worst of the heat should ease by Friday evening, forecasters caution that more advisories could be issued if high temperatures and humidity persist through the weekend. Residents are encouraged to monitor local weather alerts and remain prepared as summer heat peaks in the region.
This stretch of extreme weather serves as a reminder that heat can be just as dangerous as severe storms. Taking early precautions and checking on neighbors can make a critical difference during high-risk days like this.
