A man waits to cross the street in heavy snow on March 10, 2017 in Philadelphia.
The Philadelphia region will see more rain and mild temperatures on Friday, but wintry weather looks to set in over the long President's Day weekend.
Precipitation is likely, but weather models do not agree on the track of the storm nor the temperatures of the lower atmosphere, according to the National Weather Service.
Still, snow is likely to begin Saturday night.
In what they termed a "conservative" forecast because its uncertainty at this point, meteorologists see as much as 3 inches of snow in Philadelphia, Trenton and the far north and west cities of Reading and Allentown.
In between, in places like Coatesville, Chester County to Norristown, Montgomery County to Doylestown, Bucks County, as much as 4 inches of snow is expected.
(Some models show the possibility of locally-higher amounts but for now there is low confidence in that scenario.)
Far South Jersey and the Jersey Shore will see less than inch and perhaps no accumulation by the time the fast-moving storm moves out.
The precipitation should end by sunrise on Sunday, which looks to be otherwise dry.
Temperatures are expected to rise again for the start of the workweek, with showers or a period of rain on Monday and perhaps Tuesday, meteorologists say.
Temperatures on Tuesday and Wednesday could set records for the date with highs expected to approach 70.
