Honestly, if you've lived in Philadelphia for more than a week, you know the sky has a bit of a personality disorder. One minute you're walking down Walnut Street thinking about whether it’s too early for a Rita’s water ice, and the next, a gust of wind off the Delaware is trying to take your umbrella—and your dignity—with it.
Right now, everyone is obsessing over the philly ten day forecast, and for good reason. We are currently sitting in that mid-January sweet spot where the "winter wonderland" vibes start to wear thin and the "I just want to see a leaf" vibes kick in.
The Immediate Mess: Snow and Slush
Let’s look at the numbers because they don't lie, even if the clouds do. Today, Sunday, January 18, 2026, we're dealing with a high of 34°F and a low of 19°F. If you looked out your window this morning, you saw the white stuff. There’s about a 57% chance of snow during the day, which usually means the kind of slush that turns the Schuylkill Expressway into a parking lot.
The wind is coming out of the north at a lazy 7 mph, but don't let that fool you. The humidity is sitting at 94%, which makes that 34 degrees feel like it’s biting right through your coat.
Tomorrow, Monday, January 19, things dry out. We're looking at a high of 35°F and a low of 16°F. It'll be sunny, which is great for the soul but terrible for the ice patches. If you’re commuting, watch the black ice. The wind picks up to 12 mph from the southwest, so it’s going to feel brisk, to say the least.

The Polar Dip and the Fake Spring
Here is where the philly ten day forecast gets really disrespectful. Tuesday is going to be a reality check. We're talking a high of only 22°F.
Twenty-two.
The low hits 14°F. It’ll be sunny, but that’s just the universe mocking us at that point. You’ll want the heavy-duty thermal gear for this one.
But then, because Philly loves a plot twist, we hit Thursday, January 22. The temperature jumps up to 43°F. That is a 21-degree swing in 48 hours. This is exactly why everyone in this city has a permanent head cold from January to March. It’s partly sunny, the snow starts to melt into those giant puddles at every street corner, and you’ll probably see at least one guy in South Philly wearing shorts just because it's above freezing.

Don't get too comfortable in those shorts. By next weekend, we’re sliding back down the thermometer. Saturday, January 24, brings a high of 26°F and a low of 10°F.
Then, Monday, January 26, looks like the next big event. We’ve got a 70% chance of snow with a high of 23°F and a low of 12°F. The wind is going to be screaming at 19 mph from the northwest. That is "stay inside and order a cheesesteak" weather.
Why the Philly Forecast is So Hard to Predict
You might wonder why the weather apps seem to change their minds every three hours. Basically, it’s the geography. We’re caught between the warm-ish air coming off the Atlantic and the cold air dumping down from Canada. If a storm track moves just 20 miles to the east, we get nothing but a few flakes. If it hugs the coast, we’re digging out for three days.
Meteorologists call this the "I-95 Corridor Curse." It’s a constant battle of rain versus snow.

Survival Tips for the Next 10 Days
- Salt your walk now. Don't wait for the Sunday night freeze. Once that 19°F low hits tonight, whatever melted today is becoming a skating rink.
- Layers are your best friend. Monday is 35, Tuesday is 22. You basically need a different wardrobe for every day of the week.
- Check your tires. With the wind hitting 19 mph late next week and temperatures bottoming out at 8°F on Sunday night (Jan 25), your tire pressure is going to tank.
The philly ten day forecast shows a city in transition. We’re moving from messy snow to deep, dry cold, with a weirdly "warm" 43-degree day tossed in the middle just to keep us on our toes.
Keep an eye on Monday, January 26. That 70% snow chance with high winds could turn into a genuine mess for the Monday morning commute.
Next Steps for Philadelphians:
Check your ice scraper today before the Monday morning freeze. If you're planning to travel toward the end of next week, keep a close watch on the January 26 system, as the high winds and low temperatures are a prime recipe for significant travel delays. Stay warm, stay dry, and maybe keep an extra pair of socks in the car—you’re gonna need ‘em.
