A late-weekend weather system appears likely to drop three to five inches of snow on Centre County starting Sunday afternoon, according to the National Weather Service.
That projection reflects a slight increase from an earlier forecast that predicted two to four inches.
Snow should fall in the area largely after 2 p.m. Sunday, with one to three inches of daytime accumulation possible, the weather service was reporting Sunday morning. Additional snowfall late Sunday into early Monday might amount to one to three inches more, but it should ease by about 3 a.m., according to the weather service.
It warned of slippery road conditions in a winter weather advisory issued for Centre and Clearfield counties. The advisory will be in effect from noon Sunday until 1 a.m. Monday, the weather service said in an update on Sunday morning. An earlier version of the advisory had been set to expire at 7 a.m. Monday.

Monday should be partly sunny before a slight chance for snow returns Tuesday, according to the weather service.
Elsewhere, the weather service has issued a winter storm warning for much of eastern Pennsylvania with heavy wet snow and sleet and accumulations of four to eight inches expected. Forecasters warned that travel in that region could be difficult amid snowfall rates up to an inch an hour, particularly closer to Interstate 95.
Hazardous conditions in eastern Pennsylvania could remain for Monday morning’s commute. Forecasters expect as much as seven inches in parts of Lancaster and York counties. Several inches are expected in western Pennsylvania.
