HATBORO, PA —A winter weather advisory begins Friday morning, as another storm bringing several inches of snow and dangerous driving conditions heads to southeast Pennsylvania.
The winter storm warning will be in effect from 4 a.m. to 10 p.m. Friday in Delaware, Philadelphia, Chester, eastern Montgomery and Lower Bucks counties due to dangerously icy conditions, and the chance of 5 to 6 inches of snow accumulation.
Travel could be very difficult, with hazardous conditions impacting the morning or evening commute, said forecasters.
Snow is expected to begin between 4 a.m. and 7 a.m. Friday, continuing throughout the day with the steadiest snowfall from late morning into the afternoon.
“Almost the entire area will see accumulating snow,” the NWS said, adding that most counties will see 2 to 5 inches of snowfall, although between 4 and 6 inches of accumulation is possible for some localities in southeastern Pennsylvania.

Snowfall is expected to taper off from west to east late Friday afternoon through Friday evening, though forecasters said that freezing or near-freezing temperatures are expected to linger through Sunday.
"Plan on slippery road conditions," the National Weather Service said. "The hazardous conditions could impact the morning or evening commute. Temperatures will rapidly drop into the teens late Friday night. Any untreated roads will become icy and dangerous."
The new storm will trigger “deicing operations as the snow spreads across the major airport hubs and the smaller regional airports,” according to an AccuWeather report. “Flight cancellations will mount as airlines fall behind schedule and crews and aircraft are displaced.”
"This will be a colder storm than most have grown accustomed to in much of the Midwest and the Northeast in that the lower ground and air temperatures combined with the fluffy or grainy nature of the snow will quickly accumulate on streets and highways," AccuWeather meteorologists said.
The Horsham Chief's Advisory Team also advised residents to be safe in the upcoming storm, noting that some parts of Montgomery County could receive up to 6 inches of snow locally.
In the beginning of the week, a snowstorm brought almost 4 inches of snow to Norristown and Plymouth Township, and about 3 inches to parts of Horsham.
Here is the forecast through the weekend for eastern Montgomery County, from the National Weather Service:
Thursday Night: Cloudy. A chance of snow after midnight. Little or no snow accumulation. Not as cold. Near steady temperature in the mid 20s. South winds around 5 mph, becoming northeast after midnight. Chance of snow 50 percent.
