Rounds of thunderstorms moved through Central Texas on Saturday, with some storms containing large hail and strong winds. Many residents reported that the thunder sounded unusually loud. Meteorologists say this is due to a temperature inversion, where cooler air is trapped at the surface with warmer air above, causing sound waves from thunder to refract and bend back towards the ground, making the booms seem louder.

Why it matters

Temperature inversions are a common weather phenomenon in Texas, but they don't always coincide with thunderstorms. When they do, it can lead to an unsettling and amplified experience of severe weather for residents, potentially causing anxiety or concerns about the intensity of the storms.

The details

Typically in a thunderstorm, sound waves from thunder travel upwards into the colder parts of the atmosphere. But with a temperature inversion in place, the sound waves refract, or bend, back towards the surface, making those booming thunderclaps seem much louder. This is because the dense, cold front that moved through the state on Saturday undercut the warmer, lighter air from the Gulf and Pacific, trapping the cooler air at the surface.
