Ice Storm in Green, Kentucky

Ice accumulations ranged from 0.1 inches to 0.4 inches across Green County, with the heaviest icing in the northern part of the county. Numerous trees were downed, and there were numerous vehicle accidents.

An arctic airmass was centered over the northern Plains, and Kentucky and southern Indiana were positioned directly along a volatile boundary between the arctic air mass and a warm and moist tropical airmass associated with the Gulf of Mexico. The vertical temperature profile was ideal for the formation of freezing rain. The arctic air wedged itself beneath a warm and moist layer aloft. As energy associated with the jet stream passed over the Ohio Valley, a mix of wintry precipitation occurred. A large swath of freezing rain occurred, stretching mainly west to east across Kentucky.
