Temperatures were stuck in the teens, with wind chills as low as 17 below, and officials were warning parents that children were at risk from the dangerous cold.
A wintry pattern could persist for the next two to three weeks, the National Weather Service said. A touch of snow is possible Thursday and Saturday, and perhaps something more substantial early next week, forecasters said.
The 13.5 inches measured officially was one of the biggest snowfalls in Philadelphia in records dating to 1884. This also marked the first time that the city had three 6-inch-plus snowfalls so early in a season. The seasonal total now stands at 33 inches compared to an average of 22.2 for an entire season.
Already the winter of 2013-14 ranks in the top 25 for seasonal snowfall, the National Weather Service said, and typically February is the snowiest month.
