If you stepped outside in Center City this morning, you probably didn't need that heavy parka you bought for the "impending doom" of winter. It’s actually kind of nice. But don't let the 55°F high today, Wednesday, January 14, fool you into thinking we're out of the woods. Philadelphia weather is basically a mood ring that’s currently stuck on "confused."
We’re sitting in that weird pocket where the morning feels like a soft spring day, yet the National Weather Service is already whispering about snow showers by tomorrow. It’s the classic Philly fake-out. You’ve probably seen the phila 5 day weather forecast popping up on your phone with those little rain-cloud-meets-snowflake icons, and honestly, they aren't kidding.
The Immediate Shift: From Mild to Wild
Today is the peak of the "warmth." We’re looking at a high of 55°F with plenty of clouds. It feels heavy, though. That’s because humidity is hanging around 46%, and a south wind is dragging in some moisture.
Tonight is where the script flips.
A cold front is moving through, and it’s a "game-changer," according to local meteorologists at CBS Philadelphia. By late evening, light rain will start. As the temperature drops toward a low of 42°F overnight, that rain has a decent chance (about 35%) of mixing with some white stuff. It won't be a blizzard, but it’ll be enough to make the Schuylkill Expressway a bit greasy for the early morning commuters.
The Next 48 Hours: Reality Check
Thursday, January 15, is going to feel like a punch in the face.
The high only hits 41°F, which is a 14-degree drop from today. Plus, the wind is shifting to the west at 15 mph. That means the "real feel" is going to be well into the 20s. We might see some lingering snow flurries in the morning, but the sky should clear up by the afternoon.
Friday stays chilly.
- High: 36°F
- Low: 24°F
- Conditions: Partly sunny but brisk.
It’s a great day for staying inside or maybe hitting the Rothman Orthopaedics Ice Rink at Dilworth Park if you’re a glutton for punishment. Just wear the wool socks.
The Weekend Outlook: Mixing It Up
Saturday, January 17, is the day everyone is watching. Right now, the phila 5 day weather forecast shows a messy mix. We’ve got a 40% chance of rain and snow during the day.
The temperature is climbing back up to 42°F, which is the "danger zone" for messy slush. It’s not cold enough for a beautiful snow blanket, but it’s definitely not warm enough to just be a pleasant rain. If you have plans at the Reading Terminal Market or want to catch the 76ers, give yourself an extra twenty minutes for travel.
Sunday brings the arctic air back in force.
Expect a high of only 32°F. That’s freezing, literally. The sky will stay mostly cloudy, and the wind will keep that bite in the air. It’s the kind of day where the "sunny south" forecast the Old Farmer's Almanac predicted for early January feels like a distant memory.
Why Our Forecasts Keep Changing
You might wonder why the apps can't seem to agree on whether we're getting an inch of snow or just a cold drizzle. It comes down to "phasing."

Meteorologist Justin Berk recently pointed out that for a real-deal winter storm in the Eastern US, you need the northern and southern branches of the jet stream to link up. Right now, they’re basically ignoring each other. They’re like two people on a bad date at a diner on Broad Street—sitting at the same table but not talking.
Without that connection, we just get these "disturbances." Little pieces of energy that trigger flurries or light rain rather than the massive Nor'easters we used to see more often.
Climatology vs. Reality
January is statistically the coldest month for Philadelphia. Usually, we see an average high of about 40°F. This year, we’re seeing a lot of volatility. One day it’s 55°F, the next it’s 32°F.
This isn't just "bad luck." It’s part of a broader unsettled pattern. While Western Maryland is getting hammered with over 50 inches of snow this season, the I-95 corridor—where we live—is stuck in this loop of "almost snow."
Practical Steps for the Rest of the Week
Since the phila 5 day weather forecast is leaning into the cold, you need to prep for the freeze.
- Check your pipes tonight. If you live in an older rowhome in South Philly or Fishtown, those drafts are real. When it hits 24°F on Friday night, a little drip in the sink can save you a massive plumbing headache.
- Salt the sidewalk Friday evening. Don't wait until Saturday morning when the rain-snow mix starts. If you get a layer of salt down before the moisture hits, you won't end up with a sheet of ice on your front steps.
- Layers are your best friend. Wednesday is a hoodie day. Thursday is a heavy coat day. Saturday is a waterproof-everything day.
- Mind the wind. Thursday’s 15 mph gusts will knock over your empty recycling bins. Trust me, you don't want to be chasing a stray milk carton down the street in 40-degree weather.
Basically, the next five days are a transition period. We’re moving away from the mild start of the month and heading into the true "meat" of winter. Keep an eye on the Saturday morning updates, because that 40% chance of snow could easily swing up or down depending on how that coastal energy develops.
For now, enjoy the 50s while they last. They’ll be gone by dinner time.
