Wider weather episode

A complex low pressure system brought with it deep moisture from the Gulf of Mexico as it moved across the central Appalachians, overriding a shallow layer of sub-freezing temperatures within high pressure established across the lower mid-Atlantic. This resulted in widespread freezing rain across the large portions of the Virginia, as well as a mixture of freezing rain, sleet and some snow further west across the mountains. Freezing rain accumulations across portions of Southside Virginia were the highest experienced in several years, ranging from widespread 0.25 to 0.5 inch accretions, with locally higher accretions of 1 inch in thickness. The icing from this freezing rain weighed down trees and tree limbs, as well as power lines and power poles, causing a great many of them to snap. For some counties, there were reports that nearly 90 percent of the residents lost power, with some remaining without power for over a week. Numerous automobile wrecks were noted due to ice causing slick roadway surfaces. Some injuries were noted, but no known fatalities occurred due to this storm.
