Chances are good for North Texans to see snow falling on Christmas Day.But whether any of it sticks is less certain, said Jennifer Dunn, a meteorologist with the National Weather Service in Fort Worth.The agency is predicting a 70 percent chance of precipitation Tuesday, starting with rain after 1 a.m., followed by a possibility of snow in the early afternoon.That's because an arctic front is expected to push through the region after lunch and drag the mercury into the low 30s. The front will mix with ample moisture in place, which could make good on a lot of people's hopes for a white Christmas."There's a good possibility for at least some snow," Dunn said. "We're expecting subfreezing temperatures in early afternoon and that will facilitate the snow."If snow does fall, it will probably be from 1 p.m. to 4 p.m., with accumulations of 1 inch or less in some areas, the weather service says.But balmy weather in recent weeks has left ground temperatures rather warm, which could prevent snow from accumulating on surfaces, Dunn said.That could change, she added, if the arctic air is powerful enough to rapidly chill the soil.Still, it will be plenty soggy, which could create icy-road hazards Tuesday night, Dunn said.Two to 4 inches of snow is expected to fall near the Red River area of North Texas, and the front is expected to drop 4 to 8 inches of snow in Oklahoma.Folks traveling for the holiday can also expect powerful north winds of up to 20-30 mph, with gusts to 35 mph, the weather service says. Temperatures could reach the low 20s after sundown Tuesday, the weather service says."There likely will be a wind advisory at some point," Dunn said. "Wind chill factors will be in the single digits and teens, and that will continue overnight. Bridges and overpasses might be first to freeze over."Staff writer Domingo Ramirez Jr. contributed to this report.
