Storm Timing Shifts: Latest Forecast For Sunday Snow In Eastern PA

EASTERN PENNSYLVANIA — New details on timing and expected snowfall totals have been released ahead of the incoming winter storm expected Sunday across Eastern Pennsylvania.

The timing of the storm has moved up, with snow now expected to arrive as early as Sunday morning. The snow, which could be heavy at times, could continue through the evening. A winter storm watch is in place across Eastern Pennsylvania through Sunday night.

"Widespread snowfall accumulations, with snowfall rates potentially exceeding 1” per hour, may lead to snow covered roads and difficult travel," the National Weather Service said.

Some parts of Eastern Pennsylvania could see as much as 8 inches of snow, the NWS predicts in its latest map, issued Saturday morning.

In Philadelphia, where the Eagles are set to take on the Los Angeles Rams at 3 p.m., between 3 and 4 inches is predicted.

Areas north of the city could see between 6 and 8 inches.

As much as a foot could fall in parts of the Poconos, AccuWeather predicts.

"This will likely end up being the first general snowstorm for the Interstate 95 corridor for the mid-Atlantic and New England, as storms this winter have not hit all of the areas with significant snow all at once," AccuWeather Senior Meteorologist Tom Kines said.

After the snow, bitter cold will descend upon the region. Temperatures will plummet Sunday night, and remain cold through the week. High temperatures will be mainly in the teens, with lows in the single digits or even below 0 degrees.

The coldest period will be Monday night through Thursday morning, with forecasters eyeing the chance of another round of snow Tuesday night.
