Heavy snow and ice accumulations are likely to produce hazardous travel, downed trees, and power outages from the Mid-South to the Northeast, U.S. The heaviest snow is expected along and just west of the Appalachians, and the most damaging icing is likely across parts of North Carolina.

Heavy snow will extend from the Tennessee Valley, Central/Southern Appalachians, and parts of the Mid-Atlantic, with significant rain/freezing rain over parts of the Southeast, Central/Southern Appalachians, Mid-Atlantic from Sunday morning to Sunday evening, January 16, 2022, NWS forecaster Ziegenfelder noted.1

From Sunday evening into Monday morning, January 17, heavy snow will extend into parts of the Ohio Valley, Lower Great Lakes, and Northeast. Also, rain/freezing rain will move into parts of the northern Mid-Atlantic and Northeast.

Furthermore, the rain will move into parts of the northern Mid-Atlantic and Southern New England overnight Sunday.

On Monday, as the storm moves across the Northeast, the rain will develop over the coastal regions of Maine with heavy snow inland.

Light snow will linger over parts of the Central/Southern Appalachians into the Northeast by Monday evening into Tuesday.

The heavy snow will end overnight Monday over Maine. The combination of snow and ice may cause hazardous road conditions during and after the storm.

In terms of snow rates, more than 2.5 cm (1 inch) per hour are possible over parts of the Tennessee Valley and along and just west of the Appalachians today and Monday.

Ice accumulations will expand from northeast Georgia through the interior Mid-Atlantic states, with the most damaging icing likely across the Piedmont of the Carolinas, including Charlotte, NC, and Greensboro NC, which will result in dangerous travel, power outages, and tree damage.

This high-impact winter storm over land will bring hazardous marine weather over the Atlantic offshore waters with winds nearing hurricane force to 110 km/h (70 mph), NWS OPC said.

As a follow-up, this system is expected to produce seas near 9 m (30 feet) per the OPC forecast.
