Additionally, the storm caused damage to trees and a shed near the Edinburg area. The strong winds were likely the result of a microburst, which is a strong gust of winds that results from intense thunderstorm activity.

The storm appears to have caused winds from 30-40 miles per hour Friday, but some of those winds could have been stronger.

WKBN received footage of some of the storm damage from the Edinburg area. You can see video of the storm damage below:

What is a microburst?

A microburst, or downburst, is one of the more common types of severe weather that happens in the summer months throughout the United States. First, a strong thunderstorm updraft lofts water vapor high into the atmosphere. Then, the water vapor condenses into water droplets and sometimes hail forms. Next, the rain/hail becomes too heavy for the updraft to sustain and gravity causes it to fall down to the surface.

The weight of the water/hail results in a strong surge of air that spreads out and can cause damage to trees, buildings and agriculture. Watch the explainer video below:
