Nor’easter Could Drop a Foot of Snow on the Philly Region—Here’s What to Know

A powerful nor’easter is taking aim at the Philadelphia region this weekend, and according to the latest updates from 6ABC & the National Weather Service, snowfall totals could climb as high as 8 to 12 inches across much of the area, with even higher amounts possible in pockets of South Jersey and Delaware. A Winter Storm Watch goes into effect Sunday, and the heaviest snow is expected to fall Sunday night.

This storm is expected to unfold in phases, beginning with light precipitation on Sunday morning. Areas northwest of Philadelphia will likely start with light snow showers, while the city itself may begin with a mix of rain and snow. Because ground temperatures will be above freezing early in the day, much of the first round of snow is expected to melt on contact. As the day progresses, temperatures—forecast to reach a high near 39 degrees—will begin falling sharply. Later Sunday evening, all precipitation is expected to flip to snow, setting the stage for rapid overnight accumulation.

The timing of this transition is crucial. The heaviest snow is forecast to fall overnight into early Monday, creating ideal conditions for significant accumulation. The storm will begin tapering off Monday morning from west to east as the coastal low strengthens and moves away. Drivers are urged to avoid travel Sunday evening through Monday morning due to worsening visibility and road conditions.

Forecast models point to 8–12 inches for the Philadelphia metro area, with 12+ inches possible along some coastal points in South Jersey and Delaware. Areas farther west are expected to see lower totals, though still enough to disrupt the Monday morning commute. Along the coast, strong winds—possibly reaching 50 mph—could create blizzard‑like conditions, coastal flooding, and beach erosion.

With the potential for heavy, wet snow, strong gusts, and dangerous travel conditions, residents should prepare now—charge devices, plan to stay off the roads, and keep an eye on updated forecasts as the storm approaches.
