Disruptive Snow to Slow Travel From Dallas to Raleigh, North Carolina

Cold air from Canada and moisture from the Gulf of Mexico will clash to bring a significant winter storm with accumulating snow and an icy mix in a large part of the South.

While much of the Deep South will expect rain into Thursday, a corridor of snow will set up along the northern periphery of the precipitation, reaching from northeastern Texas to North Carolina.

Travel disruptions will unfold and spread from west to east, impacting Dallas; Little Rock, Arkansas, and Shreveport, Louisiana, during the morning before advancing into Huntsville, Alabama; Chattanooga, Tennessee, and Atlanta during the afternoon.

The biggest impacts will be felt by travelers taking to the roads as snow and sleet are forecast to cause paved surfaces to become slick.

Even if the snow doesn't stick to the roads during the middle of the day, colder conditions at night can cause wet surfaces to freeze; especially on the back roads, said AccuWeather.com Senior Meteorologist Frank Strait.

Significant flight delays and cancellations are possible through Thursday morning at the Atlanta International Airport, which is one of the busiest airports in the nation.

The greatest impacts will be felt in the Appalachian Mountains, across the Carolinas, and southern Virginia through Thursday morning.

The highest accumulations are expected over the mountains, but some spots in North Carolina and southern Virginia could pick up over 6 inches.

"There's going to be a sweet spot somewhere," said Strait.

The Thursday commute could be the worst time to travel in eastern Tennessee, southern Virginia and the Carolinas due to snow-covered roads and poor visibility.

People from the northern Atlanta suburbs to Greenville and Anderson, South Carolina; Charlotte, Winston-Salem, Raleigh and Fayetteville, North Carolina; and Richmond and Norfolk, Virginia, will likely be facing a significant winter storm into Thursday morning.

Anyone that has to drive in this area on Thursday morning should allow ample time to reach their destination to account for lower travel speeds, accidents and lane closures.

Snow showers will extend into northern Virginia to the Delmarva Peninsula by Thursday morning. A small accumulation of snow is possible from Washington, D.C., to Dover, Delaware, and Atlantic City, New Jersey.

Some natural melting of the snow on the roads will occur during Thursday midday and afternoon, which may allow highway travel to improve somewhat, once roads are plowed.

Wet and slushy roads could become icy on Thursday evening as temperatures rapidly fall below freezing.

Dry weather will be the theme across the Southeast on Friday with chilly air lingering around in the wake of the storm to close out the week.
