A winter storm could bring heavy snowfall through Friday morning to central Pennsylvania, according to the National Weather Service in State College.

A winter storm warning was issued for York County beginning at 1 a.m. Thursday and ending at 10 a.m. Friday. The storm could deliver 6 to 9 inches of snow, the weather service announced. The watch also includes Adams, Lancaster Cumberland, Dauphin and Franklin counties.

Heavy snow expected, and a period of sleet mixed with freezing rain is possible late Thursday afternoon.

National Weather Service meteorologist Craig Evanego said much of the lower Susquehanna Valley could see about half a foot of snow, and most of it will fall Thursday.

The storm will also bring colder temperatures into the area, with York County seeing a high of 29 on Thursday, according to the forecast.

"It should be colder for this (system), so a higher chance of snow for much of the event and lesser of a chance for that wintry mix," Evanego said. "But as is often the case down there in the lower Susquehanna Valley, you're not too far from the potential for a mix. So it wouldn't take much of shift to get a mix back in there."

Meteorologists had a predicted a wintry mix of snow, freezing rain and sleet with less than an inch of accumulation earlier in the week for some areas, but conditions continue to change by the hour.

The weather service cautioned drivers to watch out for slippery road conditions that could impact the morning and evening commute Thursday as well as affect travel. 

"There has definitely, definitely been more snow across central Pennsylvania this winter than what we saw last year," Evanego said. "I think snowfall is just a bit above normal for the lower Susquehanna Valley this year."

Evanego said another system is expected Monday that could bring with it light snow or a wintry mix.
