Ice Storm, Freezing Rain In Philly Area: Timeline On Impacts

PHILADELPHIA, PA — A winter weather advisory has been issued for southeastern Pennsylvania as the region braces for its next winter storm, with a lengthy period snow, sleet, and freezing rain expected to impact the area from Thursday afternoon through much of Friday.

While snow accumulations are still likely to be limited in the immediate suburbs, forecasters are calling for ice accumulation that could cause tree damage, power outages, and dangerous roads.

"Ice amounts of one tenth to one quarter of an inch will lead to icy untreated roads," forecasters said in their latest briefing Thursday morning.

Snow and sleet will begin in the region after 5 p.m. It will likely be rain and freezing rain in Philadelphia and the immediate suburbs, with areas farther to the north and the west in the outlying suburbs more likely to receive some snow.

Up in the Poconos, accumulation could be up to half a foot.
