A storm system sweeping from the Ohio Valley into the Northeast will produce a swath of heavy snowfall. Cold air plunging southward coupled with moisture moving north will create significant accumulations. Winter weather alerts extend from New England to the Southern Plains. A band of heavy snow behind the low pressure center will create 3" to 6" snowfall accumulations. Near the Great Lakes, totals will be enhanced and may approach a foot. Some freezing rain and sleet may produce icy areas. The low pressure center will move away from the Northeast and into the Atlantic today (Thursday). Humidity is already in place from the Gulf of Mexico as an arctic cold front drops southward, bringing the cold air. This will setup the band of heavy snow.
