COLUMBIA, S.C. — South Carolina summers are known for increased thunderstorm chances.
The Southeast is known for heat and humidity, which can create an unstable atmosphere. This instability, along with the warm Southern temperatures, can create thunderstorms.
Air from the Gulf of Mexico is another influence. Thunderstorms are more likely to form when warm, moist air from the Gulf meets cooler air.
Additionally, warm sea surface temperatures can also be a factor. As the inland heats up during the day, a temperature difference can be made with our cooler coastal areas. A "boundary" can be made. A contrast can where thunderstorms tend to develop and possibly intensify.
