About Lightning in West Virginia
West Virginia averages 37 thunderstorm days per year, placing it above the national average of 25 days. Located at approximately 38°N latitude, West Virginia is the most mountainous state east of the Mississippi, where Appalachian terrain forces moist air upward, triggering orographic thunderstorms that are difficult to predict.
In West Virginia, warm, moist air from the Gulf of Mexico combines with daytime heating to produce convective storms. Peak thunderstorm activity occurs during May through August, when conditions align for the most frequent lightning strikes. With a population of 1.8 million residents, storm awareness and lightning safety are important considerations for anyone living in or visiting West Virginia.
