From NWS
1978: A severe thunderstorm cut a path of damage from around Sioux City through Ida Grove and Rockwell City to Webster City. Softball sized hail fell in and around Ida Grove breaking thousands of windows, totaling cars, and shredding crops. Strong winds and large hail in and around Webster City uprooted trees and damaged power lines, cars, and houses. Near Newell in southeastern Buena Vista County 3.5 inches of rain fell in just one hour, flooding basements and creeks.

1882: One of the worst tornadoes on record in Iowa traveled intermittently for more than a hundred miles across west central, central, and southeastern Iowa famously devastating the city of Grinnell. The first damage occurred near Arcadia in Carroll County, then the storm killed one person in Rippey where a well-defined funnel cloud was first seen. At the same time a second storm on a parallel track about 8 to 10 miles to the north was causing several fatalities around Ogden. The two storms had merged by the time they reached Grinnell where the college campus was devastated with F5 damage as the tornado swept through town. The tornado went on to kill at least a dozen people in Malcom, then became a straight-line wind storm turning southeastward and accelerating to nearly 60 mph causing significant damage in Mount Pleasant at around 11 pm before crossing the Mississippi River into Illinois just south of Burlington. Casualty records are incomplete, but it is likely that more than 100 people were killed by this storm with most of the fatalities in and around Grinnell. The death toll would likely have been much higher except that many of the college students were attending a ball game in a neighboring town at the time the tornado struck the Grinnell campus.
