PITTSBURGH - Winter officially arrived Friday morning, and with it came the first winter storm of the season.
Snow began to fall Friday afternoon across western Pennsylvania, but accumulations weren't expected until the evening and early morning.
Severe Weather Team meteorologist Scott Harbaugh said most areas will only see scattered snow showers throughout the day Saturday, with a possibility of an additional 2-4 inches of snowfall in the mountains.
Harbaugh said Pittsburgh will not see much, if any, accumulation Saturday.
The National Weather Service issued a winter storm warning for parts of northwest Pennsylvania on Friday. A winter weather advisory has since been canceled for Beaver, Allegheny and Wesmoreland counties, but remains in effect until 7 p.m. Saturday for parts of the state.
Snowfall totals by Saturday evening will be four to six inches north of Butler and New Castle, with six to 12 inches in the mountains.
Wind gusts to 40 mph through Saturday will keep wind chills in the upper teens and lower 20s through Saturday night.
Sunday will be a calmer, quieter day with mostly cloudy skies and highs in the upper 30s.
