Scattered severe storms moved through Kentucky Tuesday evening... These pictures were taken by Jeff and Kim Loyless in Bardstown, KY. They told me it was raining hard when the winds increased and thought a tornado was heading their way (note: they did not see one).... Possible wet-microburst (areas around Bardstown received more than 3.5" of rain with this storm). The storm hit their house between 5:45-5:50 pm Tuesday evening.
Microburst: A microburst is a small, very intense downdraft that descends to the ground resulting in a strong wind divergence. The size of the event is typically less than 4 kilometers (2.5 miles) across. Microbursts are capable of producing winds of more than 100 mph causing significant damage. The life span of a microburst is around 5-15 minutes. Microbursts are classified as dry or wet microbursts, depending on how much rain accompanies the microburst when it reaches the ground.
This WAS a 30x40 concrete block, detached garage. The winds also shoved a tool shed across their yard.
