Friday will bring a dip in temperatures and a chance for some snow and rain for parts of our region. Starting in the morning there will be a wintry mix for some and snow for others. After that moves out by Saturday the temperatures will drop even further. First Alert meteorologist Brittney Shipp has the 10-day forecast.

What to Know

  • Some light -- maybe even what some might consider festive -- snow will be falling on the Philadelphia region on Friday, Dec. 20, 2024.
  • With temps hovering above freezing in most places, not much of the snow should be sticking and some places might get mostly chilly rain.
  • Once the storm moves out, frigid conditions take over this weekend. By Sunday morning it should be feeling around zero.

Keep that umbrella handy Friday as a wintry mix of light snow and cold rain are expected to fall. 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 clipper system 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

After bright sunshine on a blustery Thursday, clouds build later in the day.

Then on Friday a fast-moving clipper system is expected to bring a mix of light rain and snow throughout the Delaware Valley. Whether you get chilly rain or some snow, will depend on your location.

In the Lehigh Valley, light snow accumulation is possible, with most areas seeing a dusting to an inch, and up to 3 inches in higher elevations. However, temperatures hovering near or just above freezing for most of the day, will limit how much sticks, especially since the ground isn’t very cold.

Closer to Philadelphia, it stays above freezing throughout the day and evening, so while rain may transition to light snow by evening, it’s unlikely to accumulate.

Temps are expected to remain above freezing into Friday night.

"Most of the snow falling will be melting," First Alert Weather meteorologist Bill Henley said.

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.

Where is most likely to see snow on the ground? When might snow fall?

Lehigh Valley, colder neighborhoods in higher elevations: Dusting to 1 inch in most areas, up to 3 inches in higher elevations. Temperatures near or just above freezing will limit how much snow accumulates on roadways during the afternoon.

Philadelphia, surrounding communities: Rain transitions to light snow in the evening, but no accumulation expected as temperatures remain above freezing.

Be ready to bundle up after the storm?

By Saturday, the clipper moves out, leaving behind blustery, cold conditions -- it will be feeling like the teens in the afternoon.

It will be chilly Saturday afternoon.

Sunday turns even colder with morning temperatures in the teens and highs only in the 20s.

That's right, it will be feeling like zero (or colder) Sunday morning in some parts of eastern Pennsylvania.

It's going to be frigid Sunday morning.

So, get ready to bundle up!
