An area of low pressure approached the Ohio Valley from the northwest on April 25th. Ahead of it, a strong warm front sharpened across southern Indiana and central Kentucky. South of the front, sunshine broke out and helped temperatures surge into the 80s, while north of the front temperatures were only in the 50s. At one point, there was a 40 degree temperature difference across the state of Kentucky from north to south! This strong front helped to focus severe thunderstorm development in the late afternoon and evening hours. Many of the storms that formed were rotating single storms, known as supercells, which dropped VERY large hail in some locations.
Below is a radar loop of the event:
As mentioned above, quite a bit of hail fell in the strongest supercell thunderstorms. Below are some pictures we received of the hail, some of which was up to 3 inches in diameter which is bigger than a baseball!

In addition to the hail, a couple of tornadoes caused damage across portions of south central Kentucky. Check out this link for more information on these tornadoes.
