What is a Derecho?

An Explanation of Storms from Friday June 29th.

Meteorologist Josh Knight explains what this complex of storms is.

 Josh taks about the storms forming as a Mesoscale Convective System. Basically it's a large cluster of very strong storms, and it lasts for several hours or more. Here is a closer look at the radar images from that Friday.

When that compex becomes so large and travels for so many miles it becomes classified as a Derecho.

A derecho has to last as least 6 hours, and it's a long line of thunderstorms with damaging winds that extend at least 250 miles.

Let's also emphasize that strong straight-line damaging winds can produce an extensive amount of damage.

It doesn't have to be a tornado to produce incredible damage like we've seen.

While derecho's are not a rare weather event, they don't happen that often especially in our area.

The one on June 29th was just an incredibly strong derecho.
