It won’t require stocking up on bread and milk, but snow, sleet and freezing rain are all expected to hit York County this weekend.

The National Weather Service has issued a winter weather advisory for York County from 1 a.m. to 4 p.m. Saturday. Meteorologist Paul Head said the area could see its first snow accumulations of the season, as well as a coating of ice.

Temperatures should remain in the 20s on Friday with some sun, but a winter storm passing west of central Pennsylvania on Saturday will warm the region and bring precipitation.

“That will flood the entire eastern United States with warm air, but cold air doesn’t like to leave, kind of like your mother-in-law,” Head said. “When the warm air moves in it will start to snow and then transition over to rain. “

However, that warm air will only be in the 40s, and the early snow is expected to become freezing rain and sleet throughout the day before turning to ice on the roads. Head said motorists should use caution while driving on highways and start prepping for winter.

The wintry mix is expected to start around midnight Friday, according to the weather service.

Drivers on Interstate 83 could experience slowdowns because of the weather.

“I would advise people to start thinking about putting winter emergency kits in their cars,” Head said. “This year we’ll be getting a real winter.”

Temperatures should remain in the 40s through Sunday morning before dipping down to the 20s again at night. There also is  the possibility of more snow that could delay Monday-morning commutes, he said.
