If you stepped outside in Philadelphia this morning, you probably felt that strange, heavy dampness that usually precedes a major shift. It is Wednesday, January 14, 2026, and honestly, the city is currently caught in a classic "weather sandwich." We are wedged right between a surprisingly mild afternoon and an incoming Arctic blast that's going to make tomorrow feel like a completely different planet.
Basically, it's one of those days where your choice of jacket at 8:00 AM will be your worst enemy by 8:00 PM.
The Current Vibe: Cloudy and Deceptively Mild
Right now, what's the weather like in Philadelphia today is mostly defined by high-altitude clouds and a breeze coming up from the south. The temperature is hovering around 47°F as of early morning, which is actually pretty comfortable for a January day in PA.
But don't let that fool you.
The high for today is expected to hit about 53°F. That's significantly warmer than our seasonal average. If you’re heading to Rittenhouse Square for lunch or walking over to Reading Terminal Market, you’ll likely see people with their coats unzipped, maybe even a few brave souls in hoodies. The humidity is sitting around 50% right now, but that’s going to climb as the day progresses and moisture gets sucked up from the coast.

Today’s Forecast Breakdown
- Morning: 40s, cloudy, and gray. Typical Philly winter aesthetics.
- Afternoon: Peaking at 53°F. It’ll feel "warm" for winter, but the lack of sun keeps it from being a "nice" day.
- Evening: This is where things get messy. A 20% to 30% chance of light rain starts after sunset.
- Overnight: The cold front hits. Expect a rain-snow mix to develop as the temperature drops toward a low of 42°F (and eventually much lower by Thursday morning).
Why This Specific Forecast Matters
Local meteorologists, including the team over at CBS Philadelphia and the National Weather Service, have been sounding the alarm about what happens after today. Andrew Kozak and other local experts are tracking a "game-changing" cold front.
While today feels like a reprieve, it’s actually the setup for a "Next Weather Alert" situation. As that front sweeps through the Delaware Valley tonight, the warm air is going to be shoved out of the way by a massive Arctic air mass.
If you're commuting from the suburbs—say, King of Prussia or Cherry Hill—you need to watch the timing of the precipitation tonight. While the city might just see a cold drizzle, those north and west of the city could see a coating of snow by daybreak on Thursday. It isn't a blizzard, but it's enough to make the Schuylkill Expressway even more of a headache than usual.
What Most People Get Wrong About Philly Winters
A lot of people think Philadelphia weather is just "cold and snowy" from December to March. That's a myth.

Philly sits in a weird geographical spot. We get the "Urban Heat Island" effect, which often keeps Center City a few degrees warmer than the surrounding counties. This is why you’ll see it raining at City Hall while it’s sleeting in Doylestown.
Today is a perfect example of that complexity. We are seeing a temperature "spike" before a crash. According to historical data from the Philadelphia International Airport (KPHL), January often sees these wild swings. One day you’re at 55°F, and 48 hours later, the wind chill is in the single digits.
The Real Feel Factor
Even though the thermometer says 53°F today, the "Real Feel" is going to stay lower because of the wind. We’re looking at southwesterly winds around 8 to 10 mph. Once that rain starts tonight, the dampness will make that 42°F low feel much more biting.
Survival Guide: What to Wear and Do
Since you’re wondering what's the weather like in Philadelphia today, you’re probably trying to plan your life. Here is the move:

The Layers Strategy
Do not wear your heaviest floor-length parka if you're going to be active this afternoon. You will sweat. Instead, go with a water-resistant shell over a fleece. You’ll want that water resistance when the evening showers start around 6:00 PM or 7:00 PM.
Travel Plans
If you have a late-night flight out of PHL or a long drive on I-95, keep an eye on the radar. The rain-to-snow transition is notoriously hard to predict to the minute. Even a tiny bit of slush can create "black ice" scenarios when the temp drops rapidly overnight.
Looking Ahead: The Arctic Blast
Tomorrow, Thursday, is going to be a shock to the system. We’re talking about a high of only 33°F with gusty winds that will make it feel like the teens. Friday will be even more brutal, with a morning low around 19°F.
Basically, today is your last chance to run errands or take the dog for a long walk without feeling like your face is going to freeze off.
Practical Next Steps
- Check the radar at 4:00 PM: This is when we’ll know exactly when the rain starts. If you can get home before then, do it.
- Salt your walk tonight: If you’re in the suburbs, putting down a little salt before the rain/snow mix hits tonight could save you from a skating rink on your driveway Thursday morning.
- Hydrate: Weirdly, these temperature swings and the dry air behind the front can dehydrate you faster than you'd think.
- Check your tires: Drastic temp drops cause tire pressure to plummet. Don't be surprised if your "Low PSI" light comes on tomorrow morning.
The weather in Philadelphia today is the literal "calm before the storm"—or at least, the mild before the chill. Enjoy the 50s while they last, because by tomorrow morning, the Arctic is coming for the 215.
