VIRGINIA — Frigid wind chills from the polar vortex will follow a few more chances of snow in the Northern Virginia region in the next few days.
The National Weather Service has issued a hazardous weather outlook in Northern Virginia and other parts of the D.C. region. On Thursday afternoon and evening, forecasters say snow showers could result in a slick coating on roads.
A potential winter commuting hazard statement was implemented for the evening commute, as forecasters expect a 30 to 50 percent chance of snow around the D.C. region.
"If this threat does materialize this afternoon and evening rush- hour, many roads could quickly turn snow covered," the National Weather Service forecast says. "This could lead to dangerous traveling conditions on untreated surfaces. If commuting this afternoon and evening, be aware of the possibility of travel disruptions."
Another chance of snow will be Sunday. The National Weather Service says "there is a slight winter storm threat Sunday" that could bring impacts to travel.

According to the Washington Post's Capital Weather Gang, models show Sunday's winter storm chance could bring a dusting or less to 1 or 2 inches of snow.
AccuWeather says accumulating snow and ice could create slippery road conditions on Sunday.
"At this time, most likely snow will have departed Washington, D.C., in time for the Presidential inauguration on Monday, but there may be slippery conditions for those traveling to the nation's capital from Sunday to early Monday morning," said AccuWeather Senior Meteorologist Adam Douty.
After that, forecasters say "dangerously cold wind chills" will affect the region from Sunday night through Wednesday morning. That's due to the polar vortex, a system of chilly polar air, making its way to parts of the U.S., including the D.C. region, according to the Capital Weather Gang.
On Sunday, forecasters believe the polar vortex will keep temperatures in the 30s on Sunday. For those attending Inauguration Day and Martin Luther King Jr. Day events, Monday could be chillier, with temperatures potentially staying below 25 degrees.
Forecasters believe Tuesday will be the coldest day from the polar vortex effect. Temperatures may reach highs in the low 20s and have lows around the teens. Wednesday will bring similar temperatures before highs in the 30s approaching the 40s in the following days.
Between the cold weather and winter storms, the Capital Weather Gang says January is shaping up to be colder and snowier than usual in the region.
