EF1 tornado in Jackson County, Iowa

An EF1 tornado developed about 2 miles northeast of Spragueville in Jackson County Iowa Tuesday evening. The tornado damaged a barn and trees at a farmstead, then continued south/southwest before hitting another farmstead. The tornado caused significant damage to a large outbuilding, then lifted in crop land. Maximum winds were estimated around 100 mph, and the path width was an estimated 50 yards. The tornado path length was nearly one mile. This was likely a landspout, or non-supercell tornado.

Numerous slow-moving storms occurred on the afternoon of June 25, lasting into the evening. These storms quickly became strong to severe, with multiple becoming supercells, which ended up producing locally heavy rainfall, damaging winds, large hail, and four tornadoes that were generally weak, but still capable of damage. Winds were generally 60 mph or greater with the stronger storms, with a corridor of winds greater than 65 mph. These thunderstorms remained nearly stationary in areas, resulting in nearly 2 to 4 inches of quick rainfall and flash flooding.
