What happened

The episode as NWS LWX wrote it up.

An area of low pressure that tracked across the region on the 11th produced between 1 and 2 inches of rainfall. Unfortunately while rain was falling during the morning hours, ground temperatures were below freezing across the Eastern Panhandle of West Virginia. This caused the rain to freeze on contact with the ground and several locations reported ice accumulations between 1/4 to ½ inch. Roads and sidewalks became treacherous and numerous trees and power lines were downed by the heavy ice accumulations. Nearly 8,500 customers in Berkeley and Jefferson counties lost power as a direct result of the storm. A few severe slip and fall injuries were reported during the ice storm in Berkeley County.

ONE FACTOR THAT WL KEEP SIG ICING POT AT BAY WL BE THE FACT THAT THE
