An intense area of low pressure moving across the northern Rockies Monday combined with a volatile air mass produced a widespread severe weather episode Monday afternoon. Storms produced tornadoes, very large hail, heavy rain, and damaging winds.
The Storm Prediction Center (SPC), issued a particularly dangerous situation (PDS) tornado watch, shortly after 1pm MDT for southeast Wyoming and northeast Colorado. Storms quickly developed across this area shortly after 3pm in the afternoon Monday. The first few storms that developed in Wyoming were very large hail producers. Hail the size of baseballs fell from a storm a few miles north of Cheyenne, Wyoming.

Storms were also producing tornadoes in Wyoming, some of which were strong. In Goshen County, Wyoming, emergency managers reported a tornado on the ground on Deer Creek road, located along the Goshen and Platte county line. Just a few miles to the southeast of Carpenter, Wyoming, a large wedge tornado was reported by storm chasers in the area.
