11:45pm radar update:
Philadelphia metro may see one last snow-shower / snow-squall in the next 30 minutes, as the front crosses the area.
This can leave a quick coating of snow.
It appears the best chance for one more snow-shower/ snow-squall is in south/central and southern NJ in the next 1 - 2 hours, as the cold front crosses the area.
A quick coating is possible.
