It is looking likely that southeastern Pennsylvania and parts of New Jersey will get at least some snow Sunday into Monday, according to National Weather Service, but a lot more is now looking possible.
Friday afternoon the NWS issued a winter storm watch for Sunday morning into Monday afternoon for the region.
The NWS early Friday morning messaging said two scenarios are depicted in current models.
“A pass closer to the coast would mean more impacts with coastal flooding, wind, snow/wintry mix, and marine navigation concerns,” the 4:45 a.m. report stated. “A pass farther southeast would mean still some light wintry precipitation (mostly snow), but lower winds, less risk of widespread tidal flooding, and less impacts overall.”
Friday afternoon the forecasted accumulation was upped to 4 to 6 inches northwest of Interstate 95 and as much as 6 to 10 inches southeast of I-95.

Heavy snow with winds gusts up to 35 mph is expected the watch said, making travel difficult.
“The current expectation is for light precipitation to begin overspreading the region from southwest to northeast some time overnight Saturday night,” the afternoon discussion stated. “As the low begins to approach from the southwest Sunday afternoon, precipitation rates should begin to increase. Temperatures during the daytime hours on Sunday are expected to be fairly warm, so precipitation will likely be rain or a rain and snow mix for most of the day.
“Sunday night, colder air will begin to infiltrate the area in concert with the heaviest precipitation rates. Therefore, precipitation is likely to change to all snow, and be heavy at times. Snow will likely come to an end from west to east by Monday afternoon.”
