Honestly, if you've lived in Willow Grove for more than five minutes, you know the sky here has a mind of its own. One minute you're thinking about a quick run to the Park and Shop, and the next, you're looking at a whiteout. Right now, Sunday, January 18, 2026, we’re squarely in the middle of one of those "stay inside and drink cocoa" situations.
The current Willow Grove weather is basically a winter mood board. We are sitting at 31°F, but it feels like 27°F thanks to a 5 mph breeze coming out of the north. It's cloudy, it’s damp with 96% humidity, and let’s be real—it feels much colder than the thermometer says.
The Heavy Snow Storm Hitting Willow Grove Today
Most people look at a forecast and think "snow" means a few flakes. Not today. We are looking at a heavy snow storm throughout the daytime. According to the latest data, there is a 100% chance of precipitation.

If you were planning on driving down York Road, maybe don't. The daytime high is only hitting 33°F, which is just warm enough to make the snow heavy and slushy, but cold enough to keep it sticking to every surface. We're expecting between 1 to 3 inches of accumulation before the sun goes down.
- Current Temp: 31°F
- Daytime High: 33°F
- Wind Speed: 9 mph (North)
- Precipitation Chance: 100% (Snow)
It’s that weird kind of Pennsylvania winter day where the UV index is a flat 1, meaning the sky is a thick, gray blanket. The air is heavy.
Tonight’s Rapid Freeze
Here is what usually catches people off guard in Willow Grove. The storm is going to clear out, but the temperature is going to tank. By tonight, the condition shifts to clear with periodic clouds, and the chance of snow drops to a measly 11%.

But check this: the low is dropping to 20°F.
That 33-degree slush from this afternoon? It’s going to turn into a sheet of ice the second the sun sets. If you haven't shoveled by 4:00 PM, you're going to be chipping at ice blocks tomorrow morning.
Willow Grove Weather: A January Reality Check
January is officially the coldest month for us. Usually, we see highs around 40°F, so today's 33°F is a bit of a chillier outlier. Historically, the Willow Grove Naval Air Station records show that we spend over half of January under overcast skies. Today is definitely fitting that trend.

I've noticed people often underestimate how the humidity here affects the "feel." At 92% humidity today, the cold isn't just on your skin; it’s in your bones. It’s a "wet cold," which is a very specific Southeast PA experience.
Why the "Feels Like" Matters
The wind is coming from the north at 9 mph today. That’s not a gale, but in 31-degree weather, it’s enough to push the wind chill down. Experts at places like the National Weather Service often point out that wind chill is more than just a number—it’s a measure of how fast your body loses heat.
Basically, dress in layers. Even if you're just running to the mailbox.
What to Do Next in Willow Grove
The snow is here, and the freeze is coming. If you're in the 19090 area, here is the move:
Clear your sidewalks now. Don't wait for tonight. Once that 20°F low hits, the slush will harden, making it nearly impossible to move without a jackhammer.
Watch the North Wind. Since the wind is coming from the north today, the front of houses facing Easton Road or north-facing driveways are going to catch the brunt of the drifts.
Plan for a Sunny Monday. The silver lining? Tomorrow looks like it’s going to be generally sunny with a high near 35°F. The "Willow Grove weather" roller coaster continues, so use today to stay safe and warm indoors.
