Des Moines, Iowa – Severe thunderstorms could rapidly intensify by mid-afternoon Friday, with tornadoes, large hail, and damaging winds all possible through the evening commute.
According to the National Weather Service in Des Moines, storms are expected to develop as early as 2 p.m., with the most dangerous conditions likely between 6 p.m. and 10 p.m. Storms will move east-northeast at around 40 mph, increasing the speed at which conditions can deteriorate across central and southern Iowa.
The highest risk zone includes Des Moines, Ames, and Ottumwa, where multiple severe storms are possible. Large hail and damaging wind gusts are the primary threats, but isolated tornadoes and flash flooding cannot be ruled out. Areas along Interstate 35 and Interstate 80 should prepare for sudden visibility drops and rapidly changing road conditions.
Northern Iowa, including Mason City and Fort Dodge, faces a lower but still notable risk for strong storms, while southern communities near the Missouri border may see repeated rounds of storms that increase localized flooding concerns.
Residents should have multiple ways to receive warnings, secure outdoor items, and be ready to take shelter quickly if warnings are issued. The severe threat will diminish after 10 p.m., but additional alerts may follow as storms exit the region.
