Honestly, if you've lived in Delaware County for more than a week, you know the drill. You check the app, it says "sunny," and ten minutes later you're looking for an umbrella because a rogue cloud decided to park itself right over Eagle Road.
Right now, looking at the weather forecast for Havertown PA, things are getting a little weird. We’re sitting in that mid-January slump where the air feels like it’s trying to bite your face off, but the sky is teasing us with just enough sun to make you think a light jacket is a good idea. It isn’t.

The Weekend Setup: Snow or No?
Here's the deal for tonight, Friday, January 16. We’re looking at a high of about 33°F, which is basically the temperature equivalent of a lukewarm cup of coffee. As the sun dips, those clouds are going to start rolling in heavy.
By the time you're heading to bed, the chance of snow starts creeping up to 40%. We aren't talking "Polar Vortex 2.0" here, but the National Weather Service is hinting at a messy mix.
- Friday night: Low around 29°F.
- Saturday: High near 42°F (weird, right?).
- Saturday night: Back down to 30°F.
The Saturday situation is kind of a headache. It starts as snow, then the temperature spikes, and it’ll likely turn into rain by 4 p.m. It’s that slushy, gray mess that makes driving down West Chester Pike a nightmare.
Why Sunday is the Real Problem
If you think Saturday's rain is the end of it, think again. Sunday morning brings a second front. We're looking at a 50% chance of snow with a high of 35°F.
But the real kicker isn't the snow itself—it's what happens after.
Sunday night, the floor drops out. Temperatures are going to plummet to 20°F. All that slush and rain from Saturday? It's going to turn into a solid sheet of ice. If you have plans for Martin Luther King Jr. Day on Monday, give yourself an extra twenty minutes just to chip your car out of its icy tomb.
Monday and Tuesday: The Deep Freeze
Monday is going to be sunny, but don't let the blue skies fool you. The high is only hitting 35°F, and by Monday night, we're looking at a low of 10°F.

Tuesday is actually the coldest day in the immediate weather forecast for Havertown PA. We’re talking a high of 23°F. With the wind chill, it’s going to feel like zero. If you're walking the dog at Merwood Park, make it a quick one.
The "Delco Factor" in Local Weather
People always ask why Havertown feels different than Philly when it comes to snow. It’s not just your imagination. We’re at an elevation of about 312 feet. That small gain in height compared to the city can sometimes be the difference between a dusting and two inches of the white stuff.
Plus, we get those southwest winds—currently around 9 mph—that like to funnel moisture right up from the Chesapeake.
What You Should Actually Do
Forget the "milk and bread" panic. This isn't a blizzard. But it is a "black ice" event.
- Salt your walk Saturday night. Don't wait until Sunday morning. If you salt while it's still slushy, you prevent the bond between the ice and the concrete.
- Check your tire pressure. These 40-degree to 10-degree swings cause your TPMS light to go off like a Christmas tree.
- Watch the south winds. On Saturday, gusts could hit 20 mph. If you have loose patio furniture or those lightweight plastic planters, move them now.
The rest of the week looks pretty quiet. Wednesday and Thursday will see a slow climb back into the upper 30s and low 40s. It’s just this 72-hour window from Friday night to Monday morning that’s going to be a bit of a circus. Stay warm, keep the scrapers handy, and maybe just stay off the roads Sunday night if you can.
Actionable Next Steps:
Check your salt supply today before the Saturday rain starts. If you’re planning to travel via SEPTA or fly out of PHL this weekend, monitor the Friday night snow totals, as de-icing operations are expected to cause delays starting early Saturday morning.
