8:45 p.m. update: York County remains in winter storm warning while the area is expected to get two days of snow.
The winter storm watch runs from 1 a.m. to 1 p.m. Thursday, said Tony Mach, meteorological technician with the National Weather Service.
"The storm is going to develop in the southeastern part of the country and move up the coast," he said. "How close the storm gets will make a different in how much snow we get. If the storm goes further away from the coast then there will be a lesser amount of snow.
Snow could arrive in the area after midnight Wednesday with an accumulation of 2 to 4 inches, Mach said.
The county has a 50 percent chance of getting now again on Thursday with possible accumulation of 4 to 8 inches. Snow would fall throughout the day and taper off Thursday night, Mach said.
High temperatures for Wednesday is around 20 degrees, while Thursday's high will be in the lower 30s, he said.
2:45 p.m. update: With the next winter storm still more than 24 hours away, the National Weather Service has extended the winter storm warning issued for south central Pennsylvania, including York County.
That storm warning now runs from 1 a.m. to 10 p.m. on Thursday.
The weather service is calling for 6 to 12 inches of snow. It says freezing rain is also possible, but not likely.
The snow will be accompanied by winds of 10 to 15 mph with gusts up to 25 mph.
Previous story: Those looking for a silver lining in the approaching snow clouds might consider all the extra time Yorkers will have to contemplate clever combinations of weather-related and apocalyptic terms.
The latest "snowmaggeddon" is expected to arrive around dinner time Wednesday and easily drop 8-12 inches of snow to York County, said AccuWeather senior meteorologist Tom Kines, but "there could certainly be more than that if there really wanted to be."
And it has been a "really wanted to be" kind of year for the York area, Kines said, with extremes including record-low temperatures, above-average snowfall and an ice storm from which Yorkers are still recovering.
So it's time to prepare again, and that's not likely to bring much excitement from anyone other than school kids, the suppliers of bread, milk and eggs, and the owners of car washes, plowing companies and ski slopes.
The National Weather Service has issued a winter storm watch in effect Wednesday night through Thursday evening as a low pressure system is expected to move north from Georgia and the Southeast and along the East Coast before moving out into the Atlantic Ocean. How long it takes to head out to sea will determine how much snow York actually gets, said NWS meteorologist Elyse Colbert.
The longer it stays inland, the more snow.
Timing: Flurries will start Wednesday evening, with snow gradually becoming heavier overnight and the heaviest snow falling from midnight to noon on Thursday. The storm will taper off by evening, but some flurries could fall until Friday morning, she said.
Wednesday's high is in the mid-20s, with a low near 20. Thursday will reach freezing, 32 degrees, with a low of 20. Friday will be the warmest day of the week, with a high near 40, Colbert said.
The storm is likely to push the York area past its most recent seasonal snowfall record, which was set back in 2010. For the winter of 2009 and 2010, there had been 36.8 inches of snow by Feb. 11, Colbert said.
There have been 29.2 inches of snow so far for this season, so a foot of snow will comfortably break that record.
The "norm" to date is 18.8 inches, Colbert said.
Last storm: With this storm approaching, most of the people who lost electricity in the last storm are back on the grid.
Met-Ed and PPL both reported they're restored power to all who lost it in the storm, but PECO reports 201 people in the southern part of York County are still without power.
