The twister passed just south of Chapman, a community of 1,400 that in 2008 lost more than 60 homes and had several school buildings and churches damaged by a similar-sized tornado that cut through the heart of the town.

The weather service says Wednesday’s tornado was a half-mile wide and completely destroyed a farmstead near Chapman.

Earlier Thursday the weather service had rated the tornado as an EF3.
