About Lightning in Wyoming

Wyoming averages 32 thunderstorm days per year, placing it above the national average of 25 days. Located at approximately 41°N latitude, Wyoming is a high-elevation state in the northern Rockies, where afternoon orographic thunderstorms develop rapidly over mountain terrain and can produce severe hail on the eastern plains.

In Wyoming, afternoon solar heating of mountain slopes drives rapid orographic thunderstorm development. Peak thunderstorm activity occurs during May through August, when conditions align for the most frequent lightning strikes. With a population of 0.6 million residents, storm awareness and lightning safety are important considerations for anyone living in or visiting Wyoming.
