US: Adverse winter weather forecast across central and eastern regions through at least early Feb. 17

Adverse winter weather is forecast across parts of the central and eastern US through at least early Feb. 17. A low-pressure system is expected to generate a swath of moderate snowfall from northeastern Missouri eastward to New Jersey and Delaware before it moves out into the Atlantic. Snowfall accumulations of 5-10 cm (2-4 inches) are likely across much of the affected area, with higher accumulations of 10-15 cm (4-6 inches) forecast over the Central Appalachians of West Virginia into the Maryland Panhandle. Hazardous driving conditions are likely in some areas due to slippery roads and reduced visibility caused by blowing snow.

As of early Feb. 16, the National Weather Service (NWS) has issued winter storm warnings across parts of eastern West Virginia, far northwestern Virginia, and the western Maryland Panhandle. Winter storm watches and winter weather advisories are in place across the rest of the affected region. Wind advisories are also in place across parts of the affected area. Officials could update and possibly extend the coverage of the weather alerts over the coming days.

Snow accumulations are likely across the affected region, especially at higher elevations. Lesser accumulations are possible where sleet and freezing rain mix with the snow and precipitation is less intense. In addition to the heavy snow, strong wind gusts will likely lead to periods of blowing and drifting snow in some areas. Sporadic power outages could occur throughout the affected region.

The winter weather will likely cause ground and air transport disruptions over the coming days. Traffic and commercial trucking delays are possible along regional highways. Dangerous and challenging driving conditions are also likely on secondary and rural roads in the affected states as maintenance crews prioritize clearing major routes. Authorities could close stretches of highways if driving conditions become too hazardous. Flight delays and cancellations are likely due to ground stops and deicing operations at airports in the region.
