Understanding Ridge Riders: Persistent Summer Storms

This clip introduces "Ridge Riders," powerful complexes of storms that repeatedly strike the same locations during summer. The meteorologist explains that these are caused by strong, stable high-pressure areas, or "bubbles" of hot air, that can remain stationary for days or weeks. He describes how these ridges influence local weather, causing hot, muggy conditions with little rain directly underneath, but creating intense, repeated thunderstorms on their periphery, leading to flood threats.
