This winter storm event was a continuation of storm conditions that existed intially as a blizzard in these counties. During this winter storm, an additional 1 to 3 inches of snow fell, with some sleet, freezing rain, and rain mixed in. East winds gusted to 22 to 26 knots (25 to 30 mph). Even some thunder was heard!
