Davenport, Iowa – Scorching heat and dangerous humidity levels are gripping the Quad Cities area today and Tuesday, with heat indices soaring between 95° and 105° during peak afternoon hours. Residents should brace for sweltering conditions and prepare for the possibility of severe overnight storms.
According to the National Weather Service Quad Cities, a marginal severe risk (Level 1 of 5) is in place through early Tuesday. A line of storms could sweep through the region between midnight and 6 a.m. CDT, bringing soaking downpours and damaging winds capable of toppling trees and flooding low-lying roads. Additional isolated storms may re-develop Tuesday afternoon as leftover boundaries spark renewed activity.
Cities across eastern Iowa and northwestern Illinois — including Davenport, Bettendorf, Moline, and Rock Island — could experience travel disruptions and temporary power outages. The heat and humidity may also impact vulnerable populations. Residents are urged to stay hydrated, limit time outdoors, and ensure pets are kept cool. Storm prep includes charging phones, securing outdoor items, and monitoring local alerts overnight.
A noticeable break from the heat is coming midweek. Cooler, less humid air will move in beginning Wednesday and continue into Friday, offering some relief after the early-week extremes.
