Snow Possible Next Week In Pennsylvania, Forecasters Say

A mild weekend will turn to more extreme weather, with the potential for snow early in the week in Pennsylvania, the National Weather Service said.

The National Weather Service has issued a Hazardous Weather Outlook, saying there is the potential for a storm coming late Monday, though the track and intensity were unknown at press time.

Accuweather predicts a storm could come as early as Sunday, but forecasters with the National Weather Service say there’s a better chance for snow Monday and/or Tuesday.

“By Tuesday, the air will likely be cold enough to support snow farther east, perhaps right to the Atlantic coast. However, how quickly that second storm forms will determine how much of the mid-Atlantic region receives accumulating snow,” Accuweather said in a statement.

Here are some more details:

• The National Weather Service says snow is expected to start Monday night and spread throughout the region by 1 a.m. Tuesday, possibly lasting until 1 a.m. Wednesday.
• Following near-record warmth this week, colder air will arrive in stages from the latter part of this week and into the second week of February, according to an AccuWeather release.
• The first storm will make its run near the East Coast during Sunday into Monday. Should the first storm track close to the coast, rain and/or wet snow could fall. Should the first storm swing well off the coast, then little or no precipitation would occur.
• The latter scenario is most likely with the early week storm. Rain will skirt the coast from the Carolinas to southeastern Virginia on Sunday.
• A second storm, however, could have significant wintry impact for the the mid-Atlantic and Northeast.
• By Tuesday, the air will likely be cold enough to support snow farther east, perhaps right to the Atlantic coast. However, how quickly that second storm forms will determine how much of the mid-Atlantic region receives accumulating snow.
• The odds of accumulating snow and the potential for a significant snowstorm will increase farther north from the upper part of the mid-Atlantic to New England spanning Tuesday into early Wednesday, according to AccuWeather.

The developing storms could bring snow for the New Hampshire primary on Tuesday.

“As with any pattern change, there is a period of uncertainty and the potential for swings in the forecast,” AccuWeather Chief Meteorologist Elliot Abrams said. “It is too early to make a call, one way or the other, until we gauge how the colder air and the two storms will interact with each other.”
