PHILADELPHIA (CBS) – A powerful winter storm will bring measurable snow, strong winds and heavy rain to the Delaware Valley this weekend. The bulk of the system’s impacts will be felt in the tri-state area on Sunday evening, and with freezing cold weather already in place, multiple winter weather warnings have been issued for parts of the region.
Wind chill dropped to zero in Philadelphia early Saturday morning. At Mount Pocono, it dropped to -26 degrees. And on Saturday night, it will be very cold again, with a record cold forecast of 10 degrees for Philadelphia.

Most of Sunday remains without precipitation before conditions quickly become active in the early evening. A winter storm warning will go into effect at 6 p.m. Sunday for the Poconos, and a winter weather advisory for the Lehigh Valley, our far northern and western suburbs, and Berks County. Nearby suburbs of PA and DE are also subject to a winter weather advisory from 6:00 p.m. Sunday to 3:00 a.m. Monday.
Southern and central Delaware will see the impacts of the system as early as 3 p.m. Sunday. Snow will begin in Philadelphia between 4 p.m. and 6 p.m. Heavy snow is possible, with a period of mixed ice pellets and freezing rain beginning between 7 p.m. and 9 p.m. before changing to rain. The rain will continue, sometimes heavy, Sunday evening and until the early hours of Monday morning.
Lehigh Valley will also see a change of rain Sunday night. In the Poconos, there could be long periods of freezing rain – and therefore ice buildup.
When the system enters the region around 6 p.m. Sunday, very strong winds are expected. Gusts of up to 50 mph could be seen across the region. Power outages are possible.

Other worries include icy roads and coastal flooding.
Look at possible snow accumulations:
- 4-6″+ in the Poconos
- 2-4″ in Lehigh Valley, Far N & W Suburbs, Berks
- Fast 1-2″ in nearby Pennsylvania suburbs
- C-2″ in the city center
The snow will then be melted or transformed into slush by the rain.
The rain will end around 5 and 6 a.m. Monday, with flurries or additional rain/snow showers possible throughout Monday. Occasional light snow accumulation is possible.
