DAVENPORT, Iowa – Summer heat refuses to let go of eastern Iowa as Friday, September 12 brings rising temperatures and clear skies. Drivers and outdoor workers in Davenport and the Quad Cities should take precautions, with highs pushing into the 90s through the weekend. Hydration, sunscreen, and limiting time outdoors during peak sun remain key.
According to the National Weather Service in the Quad Cities, Friday will be sunny with a high near 91. South winds at 5 mph offer little relief from building heat. The warming trend continues Saturday, reaching near 93, before tapering slightly Sunday. Humidity remains moderate, but long hours in direct sun could create safety risks, particularly for children and the elderly.
Travelers on Interstate 74 and U.S. 61 should expect sun glare during morning and evening commutes, especially when heading across the Mississippi River. Those headed to weekend festivals or football games across Davenport, Bettendorf, and Rock Island will need to prepare for high UV exposure. Lightweight clothing, sunglasses, and shade breaks are recommended.
Overnight lows remain mild, hovering in the upper 60s, offering limited overnight cooling for homes without strong air conditioning. Residents should monitor energy use and stay aware of possible heat-related advisories if conditions stretch into next week.
The heat wave looks short-lived. A shift toward partly cloudy skies early next week will bring daytime highs back into the upper 80s by Tuesday and Wednesday, offering a gradual cooldown after the weekend warmth.
