Davenport, Iowa – Drivers and residents in eastern Iowa will feel a sharp return of summer heat on Tuesday, with highs near 91°F pushing heat indices close to triple digits. Anyone traveling along Highway 30 or through the Quad Cities should prepare for uncomfortable and potentially unsafe heat conditions through the afternoon.
According to the National Weather Service in the Quad Cities, isolated thunderstorms could develop late Tuesday across northeast Missouri into southeast Iowa. While severe weather isn’t expected, brief downpours and gusty winds may cause delays along key corridors near the Mississippi River.
The heat eases slightly by midweek, but storm chances build. A 20 to 30 percent chance of rain lingers Thursday into Friday, especially for areas west of the Mississippi. Stronger storms aren’t anticipated, but residents should remain alert as temperatures swing from the upper 80s into the upper 70s by the weekend.
Tuesday’s conditions pose health risks for outdoor workers, students, and vulnerable populations. Local officials urge residents to stay hydrated, limit strenuous activity during peak afternoon hours, and check on neighbors without air conditioning. Those driving should store extra water in vehicles and avoid leaving children or pets in parked cars.
Hot afternoons will give way to cooler, more comfortable evenings later this week, with temperatures dipping into the low 60s overnight.
