Update: The National Weather Service has issued a winter weather advisory for south central Pennsylvania, including York County.

The area could see 1 to 2 inches of snow this evening, along with a light glaze of freezing rain.

The snow will mix with freezing rain later this evening, before tapering off to snow flurries.

The winter weather advisory is in effect until 3 a.m., and the weather service warns that untreated roads will be snow covered and slippery.

The weather service is also forecasting a more significant storm expected to hit the area Wednesday afternoon into Thursday morning.

Yorkers might see that much sought after white Christmas, as forecasters are predicting a light accumulation Monday afternoon.

On Christmas Eve, Santa and his reindeer may trek through an inch of snow throughout York County, according to information from the National Weather Service.

Meteorologist Kevin Fitzgerald said low pressure moving from the Ohio Valley could sprinkle the region with an inch of snow before it tapers off late evening on Christmas Eve, when temperatures are supposed to reach a high of 38.

The Christmas forecast for the area is partly sunny with temperatures in the high 40s, he said.

Snow: People returning unwanted gifts to stores or looking to cash in gift cards Wednesday could encounter slippery roads on the way.

A second storm, slated to hit York on Wednesday, will pack a slightly stronger punch that includes snow, sleet, freezing rain and plain old rain.

"The second storm that comes in will be a bit more pungent," said Mike Pigott, a meteorologist with AccuWeather.

Snow, sleet and freezing rain are expected early Wednesday but should give way to rain as the day goes on, and temperatures will remain in the high 30s, Fitzgerald said.

Forecasters said it's not clear how much precipitation can be expected with that storm.

Forecast: Winter weather is expected to stick around Thursday with flurries possible as temperatures hold steady in the high 30s.

The week will round out with a partly sunny but cold Friday, with a high of 35 expected.

But the biggest snowstorm of the week might happen on Saturday, Fitzgerald said.

A snowstorm moving along the East Coast will likely have the most impact in New England, but it could dump some snow on York County. Or it could be rain, he said.

As of Monday morning, it was unclear if or how much snow accumulation or precipitation the potential Saturday storm would produce in York County.

"This is all really normal for December," Fitzgerald said.
