| 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. | |||||||||||
