Honestly, if you just stepped outside in Center City, you already know. It’s cold. Like, "should have worn the heavy parka" cold. Right now, the temperature in Philadelphia is sitting at exactly 32°F.
It’s that weird, biting kind of cold where the air feels heavy because the humidity is pegged at 91%. Usually, we think of humidity as a summer problem—that "it's not the heat, it's the humidity" cliché—but in January? It just makes the dampness seep right through your layers.
What’s Actually Happening with the Philadelphia Temp Right Now
We are officially in a Winter Weather Advisory. It kicked off at 6:00 AM this morning and isn’t letting up until 8:00 PM tonight. If you're looking out the window, those gray skies aren't just for show. We’ve got cloudy conditions with a light northeast wind moving at about 2 mph. It’s barely a breeze, but at the freezing mark, even a tiny gust feels like a slap.
Basically, we’re stuck in a "slush sandwich." Yesterday was a mess of rain and snow that left everything damp, and today is the sequel.

The Hour-by-Hour Reality
Don't let the "35°F high" for today fool you. We aren't going to be basking in mid-30s warmth for long.
- Morning/Midday: We're hovering around freezing. Light snow is likely (about a 50% chance), so if you're heading to Reading Terminal Market or just walking the dog, watch for those slick spots on the bricks.
- Late Afternoon: The precipitation might taper off, but the dampness remains.
- Tonight: The clouds finally break, but that's a double-edged sword. Clear skies mean all that "warmth" escapes. We're looking at a low of 23°F.
Everything that’s wet right now? It's going to be a sheet of ice by the time you wake up tomorrow morning.
Why the "Feels Like" Temp in Philadelphia is the Real Story
The thermometer says 32°F, but your skin says something else. Meteorologists call this the wind chill or the apparent temperature. When you factor in that 91% humidity and the light northeast wind, the air is effectively sucking heat away from your body faster than it would on a dry day.

Experts at the National Weather Service in Mount Holly have been tracking this "Two-Part" storm system. Part one was the early morning burst. Part two is the moisture wrapping back in from a southern storm passing off the coast. It's a classic Philly setup where the I-95 corridor acts as the dividing line between "just annoying rain" and "shoveling snow."
Regional Breakdown: It’s Not the Same Everywhere
Philly weather is famously local. While the Philadelphia temp right now is holding at freezing at PHL Airport, things look different if you head even twenty minutes in any direction.
- Lower Bucks and Montgomery Counties: You've probably seen more "stickage" on the grass. Temperatures there often run 2-3 degrees cooler than the heat island of the city.
- Delaware and South Jersey: It’s mostly been a cold, miserable rain or a slushy mix.
- The Lehigh Valley: They’re the big winners (or losers) today, with totals hitting up to 5 inches in some spots.
Looking Ahead: The Big Freeze is Coming
If you think today is bad, wait until Tuesday. We’re about to hit a massive temperature cliff.

Tomorrow (Monday) stays steady with a high of 35°F, which is actually the seasonal average for Philadelphia in mid-January. But Tuesday? The bottom drops out. We are looking at a high of only 25°F and a bone-chilling low of 14°F.
That’s "pipes-freezing" territory.
How to Handle the Next 24 Hours
Since we know the Philadelphia temp right now is right at the freezing point, the biggest risk is the freeze-thaw cycle.
- Salt early: Don't wait for the ice to form tonight. If you have slush on your sidewalk, get it clear now before the 23°F low hits.
- Check your tires: Cold air makes tire pressure drop. If your "low air" light came on this morning, it’s not a glitch; it’s physics.
- Layer up: Moisture-wicking base layers are your best friend today. Stay away from cotton if you're going to be outside for a while, as it holds onto that 91% humidity and keeps you shivering.
The reality of Philly in January is that we're always one degree away from a disaster or a puddle. Right now, we're sitting right on that line. Stay warm, stay dry, and maybe grab an extra soft pretzel—you've earned the carbs today.
Actionable Next Steps:
Check your exterior faucets and ensure any hoses are disconnected before the temperature drops to the teens on Tuesday. If you have elderly neighbors, now is a good time to check that their heating systems are keeping up with the high humidity and freezing transition occurring over the next 12 hours.
