Wet Microburst
This thunderstorm formed ahead of an outflow boundary near Goodfield, Illinois. The updraft at the beginning was strong enough to keep the rain aloft. Then suddenly, a column of sinking air within the thunderstorm rushed to the ground, bringing strong winds and torrential rain. This is known as a microburst. It is a very localized event that can be difficult to predict. For a pilot, a microburst is the most dangerous part of a thunderstorm. Microbursts have caused numerous plane crashes, they are especially dangerous when an aircraft is trying to land.
