The final weekend of August will bring a noticeable change in the weather for eastern Iowa and western Illinois. According to the National Weather Service in the Quad Cities, a cold front will move through Friday night, bringing a chance of a few isolated showers and thunderstorms, mainly north and west of the metro area. Most of the region will remain dry, and no severe storms are expected. Overnight lows will dip into the low- to mid-60s, providing an early taste of the cooler air to come.
Saturday will feature partly sunny skies with highs ranging from the low 70s to the low 80s. This marks the beginning of a stretch of comfortable late-summer weather, as cooler, drier air settles across the region. Travelers and weekend plans should go largely uninterrupted, though those in northern Iowa and western Illinois may encounter brief showers overnight Friday before conditions improve.
From Sunday through Tuesday, residents can expect sunny skies and pleasant afternoons. Temperatures will remain below normal for late August, with daytime highs holding steady in the upper 60s to mid-70s. Overnight lows will be especially refreshing, falling into the 40s and 50s by early next week. The crisp mornings and mild afternoons will offer ideal conditions for outdoor activities, from weekend festivals to late-summer yard work.
By midweek, the pattern holds firm with continued sunshine and comfortable temperatures. Wednesday will bring highs in the 70s with another dry, pleasant day. The extended outlook suggests this stretch of cooler, settled weather could last into early September, a welcome break from the heat and humidity typical of the season.
In short, the Quad Cities region is in for several days of cooler-than-average conditions and abundant sunshine following the passage of Friday night’s front. While a few scattered showers may brush the northern and western counties to start the weekend, the broader trend points toward dry, stable weather with seasonably crisp mornings and mild afternoons.
