(Sean Philip Cotter, York Dispatch)

Yorkers might not have awakened to a winter wonderland -- or even to any falling flurries -- but 4 to 8 inches of snow is in the process of coming down on central Pa., said the Nation Weather Service on Saturday.

Snow has begun to fall fairly heavily on York County. The NWS website puts visibility at half a mile in York City as of 4 p.m.

Around 3 a.m. Saturday the NWS updated their winter storm warning for central Pa. The NWS, which had previously stated that snow would start around sunrise, pushed the flakes' estimated time of arrival back a little bit. The snow began to fall in the early afternoon and it's supposed to continue into the night. The NWS warning is in effect through 4 a.m. Sunday.

The warning predicts 6 to 8 inches for central Pa., and York County may sit at the lower end of that spectrum; the NWS' more York-specific forecast foretells 2 to 5 inches around York County during the day Saturday with more accumulation during the night.

Snow may fall at more than 2 inches per hour at times, a heavy rate that could cut visibility down to below a quarter mile, the NWS said. That and the freezing rain that the NWS said will begin between 7 and 10 Saturday night could make for poor road conditions.
