A new push of frigid air will trigger the next round of wintry precipitation across the Northeast in the form of snow showers and locally heavy snow squalls into Wednesday night.
While the snow showers will vary in intensity and duration from place to place, they will bring the risk of slippery roads and sidewalks, as well as flight delays due to deicing operations.
The snow showers will dip as far south as portions of Tennessee and North Carolina and will reach as far east as the Atlantic coast.

The snow showers can be heavy enough to bring a sudden drop in visibility, a quick coating of snow on area highways and a rapid freeze-up.
Where the snow showers persist, a couple of inches of snow can accumulate.
Motorists should prepare for rapidly changing weather conditions along the Interstate 64, I-70, I-76, I-79, I-80, I-90, I-81 and I-95 corridors.
"There could be a few snow squalls that sweep across the Appalachians Wednesday and cause brief but dangerous whiteouts and driving conditions," said AccuWeather.com Meteorologist Jordan Root.
Snow squalls are the wintertime cousin to summertime gusty showers and thunderstorms. Thunder and lightning can occur in some locations with the heaviest squalls.
Frigid air rivaling that of early this week will push from the Midwest to the East and South following the snow showers.
As temperatures fall any areas made wet and slushy by the snow showers will freeze, including around Pittsburgh, New York City, Philadelphia and Washington, D.C.

As the system producing the snow showers swings off the New England coast during Thursday, it is expected to strengthen and evolve into a snowstorm from to parts of Maine to New Brunswick through Friday.

Boston will miss out on most of the snow but will see occasional snow showers through Thursday. The lack of additional heavy snow comes as good news for a city that is struggling to deal with the current snow depth from previous storms.
The storm system will also bring gusty winds that will cause blowing and drifting snow. Whiteouts and poor driving conditions will impact Portland and Bangor, Maine to Fredericton, New Brunswick and Halifax, Nova Scotia.
The gusty winds will usher in more arctic air that will set the stage for another large scale winter storm that will unfold over the Central states late this week.
The new storm will spread into the Eastern states this weekend.
