Davenport, Iowa – Residents across eastern Iowa and northwest Illinois should prepare for dangerously high temperatures this weekend, with heat index values soaring to 105 degrees Fahrenheit. This extreme heat is expected to last through early next week, posing significant health risks.
According to the US National Weather Service Quad Cities Iowa/Illinois, an Extreme Heat Watch is in effect for a wide area, including cities like Waterloo, Dubuque, Cedar Rapids, Iowa City, and the Quad Cities. Heat indices from Saturday through Tuesday are expected to range between 100 and 105 degrees. Overnight lows will be unusually warm, potentially nearing or breaking records for those dates, offering little relief from the daytime heat.
The combination of high temperatures and elevated humidity increases the risk of heat-related illnesses. Residents are urged to stay hydrated, limit outdoor activities during peak heat hours, and check on vulnerable neighbors. Cooling centers may become available; local authorities will provide updates. While there’s a slight chance of thunderstorms Sunday night, confidence in lower temperatures is low, meaning the heat will likely persist.
Warnings remain in effect through Tuesday, and the National Weather Service may extend or expand advisories as conditions evolve.
