Davenport, Iowa – Residents across eastern Iowa and northwestern Illinois have a short window to enjoy cool, quiet weather before thunderstorms return to the region, with some storms potentially becoming strong by Wednesday.
According to the National Weather Service Quad Cities office, high pressure will keep conditions dry and seasonably cool through Monday before a cold front approaches Tuesday. That system is expected to bring scattered showers and thunderstorms to the area, followed by a stronger storm system on Wednesday.
Sunday night will remain mostly quiet with passing clouds and overnight lows ranging from 48 to 53 degrees. Monday will feature partly cloudy skies and continued dry weather, with afternoon highs reaching 74 to 77 degrees and lows falling into the mid-50s Monday night.
Rain chances increase Tuesday as the approaching front moves through eastern Iowa and western Illinois. Cities including Davenport, Bettendorf, Moline, Rock Island and Clinton could see scattered showers and thunderstorms develop during the day. The National Weather Service indicates little to no severe weather threat is expected with Tuesday’s activity. High temperatures are forecast to range from 73 to 79 degrees.
The greater concern arrives Wednesday when widespread showers and thunderstorms are expected across the Quad Cities region. Forecast guidance shows an 80% to 100% chance of precipitation, and the National Weather Service notes that a few storms could become strong to severe. High temperatures are expected to vary from 72 degrees in areas with persistent rain to the lower 80s where sunshine develops before storms arrive.
Residents should monitor updated forecasts through Tuesday and Wednesday, especially those with outdoor plans. Secure loose outdoor items, ensure mobile devices are charged and be prepared for changing weather conditions during the middle of the week.
Additional watches, advisories or severe weather alerts may be issued as Wednesday’s storm system approaches.
