Severe thunderstorms containing powerful wind gusts are not uncommon during the summer months as high afternoon temperatures prior to a storm help create a lower atmosphere conducive for strong wind plunging down from a thunderstorm's downdraft. This is known as a microburst. This particular storm also contained a distinct bowing shape, indicating powerful wind gust presence, and was well-supported by an upper-tropospheric disturbance aloft, adding to it's severe potential.
