As Thanksgiving eve nears, road crews and airliners in the Northeast are gearing up for a travel-impairing storm.
The system has been moving eastward since the weekend, when it brought snow and ice to the Rockies and Plains. Even unfamiliar places, such as Lubbock, Texas, received several inches of snow.
Beginning Tuesday, storminess will spread into the Northeast.
"A wintry mix of ice and snow is expected across the Appalachians with plain snow on the northwest edge of the storm," AccuWeather.com Meteorologist Erik Pindrock said.
"Snowfall of 6 to 12 inches are expected with some spots as high as 18 inches in the heaviest areas of snow, which will fall over portions of northwest Pennsylvania and western New York."
According to AAA, 43.4 million people will travel this holiday, with 37 percent of those departing Nov. 27.
State transportation departments are already bracing themselves for the event.
"In our six-county coverage area in central New York, we’ll have plow 96 trucks available with trained staffing that can go around-the-clock," Gene Cilento, press officer of the NYDOT Syracuse office said.
"We had lake-effect snow over the weekend so our crews have been out and tested."
Though the agency says they strive to have roads clear of snow and ice within two hours after a storm, they warn that snow and slush can mount on roads during the event.
"Motorists must take responsibility for driving prudently for the conditions, knowing that roads may be slippery and snow-covered during winter storms," Cilento said.
While upstate New York has received substantial snowfall due to lake-effect bands already this season, Pittsburgh, Pa., is preparing for the first major accumulation this holiday.
"All of our trucks will be in use if we get a storm of 3 to 6 inches," Pittsburgh PennDOT Press Officer Steve Cowan said.
"Our crews are prepared. We have salt on hand, our equipment is ready. We will be here around the clock Tuesday, Wednesday and Thursday."
Though the snow is forecast to fall inland, heavy rain and gusty winds will span the I-95 corridor on Wednesday, taking aim at Washington, D.C., Philadelphia, New York City and Boston.
Conditions could result in significant delays for air travelers on Wednesday.
Already, the storm has prompted about 300 pre-cancelled departures at Dallas-Fort Worth airport.
The flights were canceled in anticipation of the storm, in order to 'reduce the number of stranded travelers,' the airport wrote on its official Twitter account.
By Thursday, nasty winter conditions should clear for most of the Northeast as the storm moves off the coast.
