A powerful winter storm system that pounded the nation's midsection, wrecking holiday travel plans and dumping a record snowfall in Arkansas, began lashing the Northeast on Wednesday with high winds, snow and sleet.

The storm, which knocked out power to thousands of homes, mainly in Arkansas, was blamed in at least six deaths.

Hundreds of flights were canceled or delayed, scores of motorists got stuck on icy roads or slid into drifts and blizzard warnings were issued amid snowy gusts of 30 mph that blanketed roads and windshields, at times causing whiteout conditions.
