Quad Cities, Iowa/Illinois – A stretch of sunny, summerlike weather continues in the Quad Cities today, with temperatures topping out between 78 and 81 degrees under a mix of sun and clouds and some lingering smoke from western wildfires.
According to the National Weather Service in the Quad Cities, this calm pattern holds through midweek, but heat and humidity will build steadily. Highs on Tuesday will rise into the low 80s, followed by mid-to-upper 80s on Wednesday and Thursday, with some areas hitting 90 degrees. Humidity will climb significantly by Thursday, creating a hotter, stickier feel across the region.
Eastern Iowa and western Illinois residents should prepare for reduced air quality due to ongoing wildfire smoke. Sensitive groups, including children and older adults, are advised to limit prolonged outdoor activity early in the week.
Outdoor workers should stay hydrated and take breaks in shaded areas as heat and humidity increase mid-to-late week. This quiet weather pattern may give way to storm chances by the weekend, though no major systems are currently forecast.
More updates will follow if air quality worsens or if any heat advisories are issued.
