Des Moines, Iowa – Hail large enough to dent vehicles and damage roofs is becoming a growing concern across central Iowa tonight as strong thunderstorms develop and intensify.
According to the National Weather Service in Des Moines, residents are urged to report hail using standard size comparisons, with quarter-size (1.00 inch) or larger considered severe. Storms moving through the region may produce hail ranging from penny-size (0.75 inch) up to golf ball size (1.75 inches), with isolated reports potentially exceeding that in stronger cells.
In the Des Moines metro, including West Des Moines and Ankeny, bursts of hail could quickly accumulate during heavier storms, creating hazardous driving conditions on I-35 and I-80. Even smaller hail can make roads slick, while larger stones may crack windshields and damage siding.
Across central and northern Iowa, communities should prepare for rapidly changing conditions as storms strengthen. Areas near Ames, Marshalltown, and Boone are also at risk for hail impacts alongside gusty winds.
Residents are encouraged to move vehicles into garages or under cover, stay indoors during hail, and report sizes using coin comparisons for accuracy.
Storm threats will continue through the late evening hours, with additional warnings possible as new cells develop.
