If you thought tornado season in the United States was on its last legs, think again. On Tuesday, the National Weather Service placed parts of Kansas, Oklahoma and Texas on tornado watch. There was also a tornado warning issued for Colorado and Wyoming.

Another round of summer storms moved into Colorado on Friday afternoon, bringing the chance of scattered hail, strong wind gusts and frequent lightning.

Chris Kimvle, a meteorologist with the National Weather Service in St. Louis, said they can look at pictures and videos to confirm a tornado, but if it’s not clear, they have to send someone out to survey damage and assess the track and strength of the tornado.
