Jul 20, 2009
An unusually deep mid level trough for mid July was in place over the Ohio Valley. The resulting cool pool of air aloft helped to generate instability showers and thunderstorms. Despite marginal moisture, a few spots in Nicholas and Fayette Counties received 2 to 3 inches of rain. This was due to the slow movement of the cells and some back building characteristics.
