Tornadoes in Wyoming

Climatology
Wyoming is among the least severe weather prone states in the United States in terms of property losses. This is due to a combination of the state's low population density and geographic limitations on severe weather. July is typically the most active month for thunderstorms statewide with the exception of southwestern regions which see a peak in August. The total number of thunderstorm days averages from 30 in the west to over 50 in the east. From 1950 to 2015, Laramie County recorded the most tornadoes with 110 while Teton County recorded the fewest with only 2. Based on 1950–1994 averages, Wyoming sees the 25th-most tornadoes in the country with an annual average of 10.

Pre-1950
In a 1953 publication of the Monthly Weather Review, the National Weather Bureau Office in Denver, Colorado, reported that 56 tornadoes were confirmed between 1916 and 1951 throughout Wyoming.
