About Lightning in Missouri
Missouri averages 47 thunderstorm days per year, placing it well above the national average of 25 days. Located at approximately 39°N latitude, Missouri is at the crossroads of the Great Plains and the Mississippi Valley, where converging air masses from the Gulf, the Rockies, and Canada produce both spring severe weather and summer thunderstorms.
In Missouri, frontal boundaries and warm moist air from the south converge across flat terrain. Peak thunderstorm activity occurs during April through August, when conditions align for the most frequent lightning strikes. With a population of 6.2 million residents, storm awareness and lightning safety are critical concerns for anyone living in or visiting Missouri.
