The first of several rounds of severe weather is kicking off in the central United States with storms hammering parts of Colorado and Wyoming.
The strongest storms are expected to focus on northeastern Colorado and eastern Wyoming into Monday night, which includes portions of I-25, I-80 and I-76.
All types of severe weather will be possible in this area, including tornadoes and hail larger than tennis balls.
A tornado has lead to property damage and 1 injury in Goshen County, Wyoming, according to an emergency manager. The tornado impacted the 5500 block of county road 108 and damaged a house and overturned some tractors.
At 5:08 p.m. MDT Monday, a large and extremely dangerous confirmed tornado was located south of Pine Bluffs, Wyoming. This is a particularly dangerous situation. Flying debris and baseball-sized hail are extremely dangerous. People in the path of the storm need to seek shelter immediately.

At 4:50 p.m. MDT Monday, several thunderstorms were capable of producing tornadoes near Cheyenne, Wyoming. Two of these storms were located east of the city while another was located northeast of the city.
A portable doppler radar, called a doppler on wheels (DOW), was near the tornado to help gather research data on the storm.

At 3:13 p.m. MDT Monday, a severe thunderstorm capable of producing a thunderstorm was headed toward Wheatland, Wyoming. A National Weather Service trained spotter reported a funnel cloud near Wheatland shortly after the NWS missed a tornado warning for the storm.
This storm already has a history of producing large hail, including softball-sized hail just south of Wheatland.
