EF0 tornado in Pottawatomie County, Oklahoma

This tornado initially developed about 2 miles west-southwest of Johnson, likely in the North Canadian River valley as evidenced by the development of a Tornado Debris Signature on radar. The tornado moved northeast producing mainly tree damage, including a tree damaging the roof of a house along Garretts Lake Road. Much of the path of this tornado was estimated being in inaccessible areas.

An unseasonably warm and moist airmass was in place across the region ahead of a powerful upper wave moving out of the 4 corners region. This led to the development of numerous severe thunderstorms across Oklahoma and Texas during the afternoon and evening of the 10th. Several tornadoes were reported, along with hail larger than baseballs that impacted Norman, OK for the second time in six months, leading to millions of dollars in damages once again to homes, cars, and businesses.
