By now, you probably have heard that snow is forecast for Sunday night and Monday.
It appears to be the biggest snowfall for most areas around Pennsylvania so far this winter. Winter weather advisories and winter storm warnings are in effect from the Ohio border into New Jersey, in a line that pretty much follows the turnpike. Little is expected north of that line, with predicted accumulations increasing the farther south you go.
The heaviest amounts are forecast to occur south of the Mason-Dixon Line, across Maryland, Delaware and Virginia. As much as a foot of snow is predicted in the area in and around Baltimore and Washington D.C. and across all of Virginia.
Snow is forecast to begin in the Pittsburgh area around 7 p.m., with 3 to 5 inches falling over the next 24 hours. That area is under a winter weather advisory, according to the National Weather Service (NWS).
In Philadelphia, its suburbs and parts of southern New Jersey, the snow is forecast to start around 1 a.m. Monday and continue off and on until the storm moves out around 10 p.m. That winter weather advisory calls for 2 to 4 inches, the NWS says.
Across central Pa., the NWS forecast has changed little since this morning, with a winter weather advisory for 2 to 4 inches across Dauphin, Cumberland, Perry and Lebanon counties. The advisory goes into effect at midnight Sunday and lasts for 24 hours.
An advisory for 3 to 5 inches during the same time period has been posted for York and Lancaster counties.
Toward Gettysburg and Chambersburg, the prediction is for 4 to 6 inches, prompting a winter storm warning, according to the NWS.
AccuWeather’s forecast is pretty similar, although its totals for Lancaster and York go up to 6 inches.
The NEPA Weather Academy, which largely services northeastern Pennsylvania, posted a map on Facebook that showed a swath of 5 to 8 inches across southern Pa. and northern Md.
What is certain is that anything that falls will hang around through next weekend. Highs will struggle to top the freezing mark over the next seven days, and there’s a slight chance at this point of snow on Saturday, according to the NWS.
