|Brief Description: EVENT NARRATIVE: A National Weather Service storm survey determined a tornado that struck Burns Wyoming the evening of May 18 was rated an EF-2. One house lost its roof. Additionally, the storm that spawned the tornado produced hail the size of golfballs which accumulated to over 3 feet in depth. EPISODE NARRATIVE: Southeast low level wind flow increased ahead of a low pressure system over northern Colorado the afternoon of May 18 2010. A strong low level southeast jet combined with dynamics of the low to create a favorable environment for severe thunderstorms. By mid afternoon thunderstorms over northern Colorado began to rotate, producing a tornado just south of the Wyoming state line south of Cheyenne. Severe thunderstorms continued into the evening hours of the 18th producing severe weather across the Nebraska panhandle and extreme southeast Wyoming.|

|Brief Description: A tornado touched down near Gill. It damaged a grain bin owned by the Northern Feed and Bean of Gill. Although not confirmed, it is believed the same twister was responsible for destroying a 60-ft by 250-ft storage building south of town. The tornado also uprooted a tree near Kuner, east of Kersey. The time of the tornado was approximated. In addition several twisters, strong thunderstorm winds and large hail the size of baseballs caused several power outages in central Weld County. Power was out from Kersey to Purcell, which covered a distance of 20 miles, for about 12 hours. An estimated 400 to 500 residents were without power throughout the night. Crops in the area also received substantial damage, but no dollar estimates were available.|

|Brief Description: EVENT NARRATIVE: A powerful tornado swept north-northwestward across Weld County and into Larimer County, carving a path of destruction, nearly 39 miles in length. The tornado, up to one-mile wide at times, initially touched down northeast of Platteville and finally lifted 6 miles west-northwest of Wellington. A tornado assessment in the aftermath of the tornado revealed extensive areas of damage. On the enhanced Fujita Scale there were pockets of EF3 damage, mainly near the Missile Silo Park Campground, and to businesses and home in eastern Windsor. There was one fatality, and 78 injuries. One man was killed when he tried to escape the trailer park in his motor home. Preliminary estimates from FEMA indicated 850 homes were damaged, and nearly 300 homes were significantly damaged or destroyed. Privately insured damages totaled $147 million, and the Poudre Valley Rural Electric Associated reported $1 million of damage to electric transmission lines.
