Des Moines, Iowa – Strong thunderstorms capable of producing 70 mph wind gusts could erupt near the I-35 and I-80 corridors after 4 p.m. Friday, putting the evening commute at risk across central Iowa. Residents should finalize severe weather plans before storms redevelop later in the day.
According to the National Weather Service in Des Moines, two rounds of storms are expected — the first arriving late Thursday night into early Friday morning, followed by a potentially stronger round Friday afternoon into the evening. The greatest severe threat appears tied to the Friday afternoon and evening storms, which may produce large hail, damaging winds, and the possibility of tornadoes.
Communities including Ames, Fort Dodge, and Des Moines sit within the zone of highest concern Friday. Hail up to 1.5 inches in diameter could damage vehicles and roofs near US-20 and along I-35. Wind gusts approaching 70 mph may down tree limbs and cause scattered power outages. Farther south toward Ottumwa and along US-63, strong storms could intensify into the evening hours with heavy rainfall reducing visibility on area highways.
Forecasters note uncertainty remains regarding how far north the most intense storms will reach and how morning storms could influence redevelopment later Friday.
Residents should secure outdoor items, charge electronic devices, and ensure multiple ways to receive warnings are enabled. Additional watches or warnings are likely as storms organize, especially Friday afternoon and evening across central and southern Iowa.
