Hazardous Weather Outlook National Weather Service Quad Cities IA IL 316 AM CDT Sat Aug 15 2026 IAZ040>042-051>054-063>068-076>078-087>089-098-099-ILZ001-002-007- 009-015>018-024>026-034-035-MOZ009-010-160830- Buchanan-Delaware-Dubuque-Benton-Linn-Jones-Jackson-Iowa-Johnson- Cedar-Clinton-Muscatine-Scott-Keokuk-Washington-Louisa-Jefferson- Henry IA-Des Moines-Van Buren-Lee-Jo Daviess-Stephenson-Carroll- Whiteside-Rock Island-Henry IL-Bureau-Putnam-Mercer-Henderson- Warren-Hancock-McDonough-Scotland-Clark- 316 AM CDT Sat Aug 15 2026 This Hazardous Weather Outlook is for portions of north central Illinois...northwest Illinois...west central Illinois...east central Iowa...northeast Iowa...southeast Iowa and northeast Missouri. .DAY ONE...TODAY AND TONIGHT Rounds of heavy rain producing storms will continue into early Saturday morning. There will also be a low end severe threat in storms south of Interstate 80, with isolated severe gusts being the main concern. Very heavy rainfall and flash flooding will be the primary concern, especially where storms move repeatedly over the same area. Significant flash flooding is possible, especially in urban areas and in counties that saw excessive amounts of rain last night. Several area rivers will be on the rise and have the potential to reach bankfull or even flood stage over the weekend and into early next week. Between the episodes of storms, high heat and humidity may produce dangerous Heat Index readings near or over 100 degrees Saturday afternoon south of Highway 34 in southeast Iowa. More rounds of showers and storms are possible tonight into Sunday morning. Heavy rainfall and lightning will be the primary threats with any storm, with a low end severe threat for isolated severe wind gusts as well. .DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY We may see some residual showers and storms Sunday morning, largely posing a heavy rainfall and localized flash flood threat. Tuesday night into Wednesday, a system will bring the chance for strong to severe storms. The Storm Prediction Center has highlighted much of our area in a Day 4 Slight Risk for severe storms, or level 2 of 5 risk. .SPOTTER INFORMATION STATEMENT... Spotter activation is likely through Saturday morning and then again Saturday night. Reports of flooding would also be appreciated. ERVIN/GUNKEL
