DAVENPORT, Iowa – Clear skies and crisp fall air greet the Mississippi River Valley this morning as a quiet start gives way to a wetter stretch midweek. The first of two passing systems will bring scattered showers Tuesday evening, followed by cooler, drier air that sets up an ideal Halloween weekend.
According to the National Weather Service in the Quad Cities, Monday stays bright and breezy with highs in the lower 60s and gusts near 20 mph. Clouds increase late today ahead of Tuesday’s system, which will push widespread rain into eastern Iowa and western Illinois after 4 p.m. Showers could briefly become moderate, especially north of I-80, with rainfall totals between a quarter and half an inch.
Winds will stay steady from the east at 15 mph Tuesday, turning north behind the front by Wednesday morning. Temperatures will dip into the mid-40s by dawn Wednesday, with cooler air filtering in through the afternoon. Wednesday’s highs hold near 56 degrees, and skies begin clearing late in the day.
By Thursday and Friday, a dome of high pressure builds across the upper Midwest, bringing sunshine, light breezes, and a return to seasonable fall comfort. Trick-or-treat conditions Friday evening should be near-perfect, with temperatures in the low 50s at sunset and clear skies through the night.
Models hint that November may open with a colder pattern — the first sign that true winter air could soon sweep across the Mississippi Valley.
