Overview
Scattered strong to severe thunderstorms developed across northeast Nebraska and parts of northwest Iowa on Monday, August 27th. These storms began to intensify into severe weather limits early in the afternoon, producing golf ball size hail as it quickly advanced northeast into central Minnesota and Iowa.
After the evening was finished, isolated thunderstorms moved across south central South Dakota, becoming severe shortly after 1am Tuesday August 28th, impacting southeast South Dakota and northwest Iowa. These storms produced hail as large as golf ball size southwest and east of the Sioux Falls metro area. By around sunrise, additional severe storms developed in northwest Iowa, producing even larger hail of baseballs or slightly larger. These storms produced significant damage to cars, homes and crops near the Primghar and Sutherland areas.
