Hear a super loud clap of thunder this morning in metro Atlanta? Here’s why

ATLANTA — If you heard a huge clap of thunder this morning in metro Atlanta, you’re not alone.

Severe Weather Team 2 Meteorologist Brian Monahan said that thunder becomes especially loud during the “elevated” thunderstorms that moved over metro Atlanta last night.

“These are storms where the air that builds into them rises from a couple thousand feet off the ground rather than from the ground,” Monahan said. “While this limits the risk of severe weather, it can make thunderstorms extra-loud when thunder does happen. This occurs because the sound waves get trapped below what is called a “‘low level temperature inversion.’”


An inversion happens when the temperatures rise with height, rather than fall. The inversion acts like a lid in the low levels of the atmosphere, and the sound of the thunder bounces off of it and objects on the ground.

“Since it can’t escape upward, it amplifies the sound of the thunder,” Monahan said.
