Snow to create added travel headaches in parts of Appalachians Friday night

A swath of snow will create slick travel over parts of the Appalachians on the back side of a large rainstorm during Friday night.

A storm with torrential rain caused flooding and travel disruptions along much of the Atlantic seaboard prior to the end of this week.

“As colder air invades the storm on its back side, a wintry mix or even accumulating wet snow may fall for a time over parts of the Midwest, but more so over the western slopes of the Appalachians during Friday night,” according to AccuWeather Senior Meteorologist Alex Sosnowski.

At this time, the highest elevations of West Virginia and west-central Pennsylvania, as well as much of western New York, stand the highest probability of receiving a few to as many as six inches of wet snow Friday night.

"Motorists heading over the ridges are likely to encounter slushy to snow covered roads during Friday night," Sosnowski said.

Enough snow may fall in Pittsburgh, Pennsylvania; and Buffalo, Rochester and Syracuse, New York; to make some roads, sidewalks and runways slippery.

With the end of this week being one of the busiest travel times of the year, even a small coating of snow on roadways or runways can create major travel disruptions and lengthy flight delays.

Portions of Interstates 70, 75, 80 and 90 that lie within the threat zone may all be covered in snow at some point on Friday or Friday night.

“In the wake of the storm on Saturday, a pocket of chilly air will follow with a brief period of lake-effect snow that may pester locations downwind of the Great Lakes, especially Erie and Ontario,” Sosnowski warned.

However, the lake-effect snow is not anticipated to be heavy or long-lasting, and dry and seasonably cool conditions are set to return for a brief period from Saturday night to Sunday, ahead of an Alberta clipper storm that may bring more general snow showers to the region.
