Light rain and snow will continue to fall throughout the Philadelphia region as we brace for bitter cold temperatures. NBC10 First Alert Weather meteorologist Brittney Shipp has your forecast.
What to Know
- Some light -- maybe even what some might consider festive -- snow is falling on the Philadelphia region on Friday, Dec. 20, 2024, and will last through the early morning hours of Saturday, Dec. 21, 2024.
- With temps hovering above freezing in most places, not much of the snow is sticking and some places are getting mostly chilly rain. Philadelphia and the immediate communities saw a rain/snow mix through the afternoon.
- Once the storm moves out, frigid conditions take over this weekend. By Sunday morning it should be feeling around zero.
Keep that umbrella handy for the rest of Friday as a wintry mix of light snow and cold rain is falling throughout the region. However, for most people in the Philadelphia region, the snow shovels can stay packed away, for now.
The First Alert Weather Team is tracking a weakening clipper system and coastal low that could, however, bring up to a few inches of snow to the Lehigh Valley and high elevations of the Pennsylvania suburbs.

Here's a breakdown of what to expect:
Light snow and chilly rain
It's been a chilly, damp and dreary Friday as a mix of rain and snow continues to move through our area.
A weakening clipper system from the Midwest transferred its energy to low pressure offshore, bringing rain into Delaware and South Jersey. Cold rain fell with temperatures in the 30s and 40s into the afternoon.
In Philadelphia, the atmosphere is slightly colder and a rain-snow mix moved in during the afternoon. With surface temperatures above freezing (upper 30s to low 40s), the snowflakes melted on contact.
"Most of the snow falling will be melting," First Alert Weather meteorologist Bill Henley said.
For the Lehigh Valley and northern and western suburbs, snow showers developed Friday morning, with intermittent snow in the afternoon. Here too, surface temperatures above freezing caused most daytime snowflakes to melt.
This system lingered into Friday evening, and as temperatures cool, light snow accumulation becomes possible.
The last few snow showers will end early Saturday morning.
Weather Stories
Roads in Philadelphia and the Pennsylvania and New Jersey suburbs and northern Delaware should remain fine, but colder surfaces like grass and sidewalks north and west of the city might see some light accumulation.
That's right, in colder suburbs and the Lehigh Valley you could be waking up to a slushy mix and even some snow on grass and colder surfaces on Saturday.
Where is it most likely to see snow on the ground? How much snow fell?
Accumulations are most likely on colder surfaces like grass, cars, and sidewalks. with 1 to 2 inches possible in the Lehigh Valley. In the Pa. Suburbs and South Jersey, expect more of a slushy mix than significant accumulation.
