Depending on how the storm tracks, York County could see anywhere from 2 to 10 inches of snow Tuesday night through Wednesday, said Meteorologist Eric Finkenbinder of abc27.
If the storm takes a more southerly route, the county will see 2 to 4 inches. However, should it take a turn to the north, expect 8 to 10 inches of snow, Finkenbinder said.
"We expect the heaviest snow to be from the turnpike south," he said.
Updated at 3:13 p.m.: The National Weather Service has issued a winter storm watch for Tuesday into Wednesday, saying 6 or more inches of snow is possible from the approaching storm. Snow is expected to begin around sunset on Tuesday and continue through Wednesday afternoon.
York's biggest snowfall of the 2012-2013 season might be approaching, with forecasters predicting 6 or more inches from a storm expected to hit Tuesday night.
"We do feel this is the best opportunity we've had all winter to see a decent amount of snowfall here," said Brett Thackera, a meteorologist with abc27. "And there's a possibility for a significant amount of snowfall."
Just how much snow depends on how the storm tracks, and meteorologists Monday morning were still studying models to determine a more precise range of precipitation.
The approaching low pressure area could stay south of the Mason-Dixon line, hammering the Washington, D.C., area with about a foot of snow, Thackera said. The southern part of York County would get at least a few inches of snow, he said.
But if the storm tracks right over the Pennsylvania-Maryland line, "we're talking about some pretty good snowfall," he said. "Plan for all day Wednesday to be snow."
The snow is expected to start Tuesday night and continue until late Wednesday night, with a potential for 6 inches or more, depending on the track, he said.
The biggest snowfall recorded in York County for this winter was months ago, with 4 inches logged in York Haven on Dec. 29, said Aaron Tyburski, a meteorologist with the National Weather Service in State College.
The approaching storm is expected to surpass that, with the southern part of the county near Maryland getting about 5-8 inches, he said.
The northern part of the county could get 3-5 inches, he said.
Tyburski said the National Weather Service is forecasting snow to start around sunset Tuesday but taper off by mid-morning Wednesday.
The high temperature Wednesday will be in the mid-30s, and it'll be warm enough to melt snow the rest of the week, he said.
There will be sunny skies and highs in the 40s for the remainder of the work week and into the weekend, Tyburski said.
