A storm expected to hit York County on Wednesday afternoon could bring 2 to 4 inches of snow accumulation, said Aaron Tyburski, meteorologist with the National Weather Service in State College.
York is under a winter weather advisory until Thursday morning.
The storm was expected to begin Wednesday as a mix of rain, sleet and snow before switching to all snow in the evening, with the majority of the snowfall arriving overnight, he said.
Winds between 10 to 20 miles per hour on Wednesday will turn into gusts of 30 miles per hour overnight, which could reduce visibility for drivers, Tyburski said.
"Take it slow and give yourself some extra time going to any events this evening because we could have slippery travel at times," he said.
Snow is expected to stop falling by 7 a.m. on Thursday, with mostly sunny skies in the afternoon and a high near 45.
Thursday night will be partly cloudy with a low around 34.
Temperatures on Friday and through the weekend will be in the mid- to upper 50s, and into the low 60s on Monday.
"We are actually going to end up with quite a nice stretch of weather after this passes," Tyburksi said.
