Waves of Winter Headed East

The active pattern in the Western U.S. won't stay put. As an energetic wave moves through the heart of the country, snow and wintry mix will spread from the Rockies to the Central Plains. Winter Weather Advisories are in effect from Montana to Missouri. Snow will continue in the Rockies Thursday night, spreading east into the Heartland by Friday morning. Temperatures near freezing will allow for a light glaze of ice to accumulate on hard surfaces for the morning commute. By the evening commute, the snow will slide east into the Ohio Valley and Mid-Atlantic states. A widespread band of 1-3" is likely, with a more focused area of 3-6" between Rapid City, SD, Lincoln, NE and Kansas City, MO. Ice accumulations will likely be less than a tenth of an inch. This isn't the only round of snow for these states. A broader, more potent low pressure system will build Saturday and push through the eastern U.S. into Sunday.  The track of the weekend system will be a bit farther north. This will mean more widespread light snow, along with less wintry mix and rain potential. For WeatherNation, Meteorologist Karissa Klos.
