During which season does Mississippi typically experience its highest rainfall?

Mississippi typically experiences its highest rainfall during the spring season. This is primarily due to the combination of warm, moist air flowing from the Gulf of Mexico and the frequent weather systems that move through the region during this time. As spring progresses, the atmosphere becomes increasingly conducive to thunderstorms, which are common and can produce significant precipitation.

While summer can also bring considerable rainfall due to thunderstorms, it is often characterized by high humidity and temperatures, but the overall annual peak in rainfall amounts occurs in the spring. Winter typically sees less precipitation due to cooler temperatures, and fall does see some rain but it does not reach the levels typically recorded in spring. Therefore, spring stands out as the season when Mississippi experiences its highest average rainfall.
