What are bow echoes?

A bow echo is like a storm that bends into a shape like a bow, and it can bring strong winds or even tornadoes along the way.

Imagine you're on a playground with your friends, and everyone starts running in one direction. As they go, the line of runners stretches out and bends, like a curved path. That’s kind of what happens with bow echoes, instead of people, it's thunderstorms moving across the sky.

A bow echo forms when a long line of thunderstorms moves forward in one direction. The storms push air ahead of them, and that pushes back on the rest of the storm line. This makes the front part of the storm bulge out like the curve of a bow, hence the name.

As the bow echo moves across the ground, it can cause strong winds or even tornadoes to form along its side, just like how you might feel a gust of wind when a group of runners suddenly changes direction on the playground.

Sometimes, after the storm passes, there's a return surge of wind, kind of like the rest of your friends catching up and running past you. That’s called the backside surge, and it can also be pretty strong! A bow echo is like a storm that bends into a shape like a bow, and it can bring strong winds or even tornadoes along the way.
