March is coming in like a lion to Western Pennsylvania.
Late Tuesday afternoon, a storm is expected arrive that could dump 3 to 5 inches of snow on Allegheny County, according to the National Weather Service.
But this is "probably the last big snow" of winter, said Brad Rehak, a meteorologist at the National Weather Service in Moon.
The Weather Service issued a winter weather advisory for the region from 6 p.m. Tuesday through 7 p.m. Wednesday.
Evening rush hour Tuesday could be impacted by a mix of rain and show. Snow will be most intense Tuesday night and end by Wednesday afternoon, possibly causing hazardous travel conditions.
The advisory is in effect for Allegheny, Beaver, Greene, Washington and lower-elevation areas in Fayette and Westmoreland counties, as well as the northern panhandle of West Virginia and central Ohio.
As of today, the region has received about 10 inches more snow than average, Mr. Rehak said.
A winter weather warning has been issued for higher elevations in Fayette and Westmoreland counties, as well as Bedford, Fulton and Somerset. Those areas could get 8 to 14 inches of snow.
The warning also is in effect for Garrett, Md., and Preston and Tucker counties in West Virginia.
