If you’re stepping out in Philly this week, don’t leave home without your umbrella. A stretch of soggy weather is about to roll in, and forecasters say the rain could last straight through Friday. Monday afternoon kicks off the wet spell, with scattered showers expected to grow more widespread as the week goes on. It’s not just a passing sprinkle — this could be one of the rainiest weeks we’ve seen this spring.
After a relatively dry and mild weekend, a low-pressure system moving across the eastern U.S. is set to bring several days of gray skies, damp streets, and cooler-than-usual temperatures to much of Pennsylvania — especially in the Philadelphia region.
When Will the Rain Begin?
The first signs of this wet weather will likely show up Monday afternoon. The morning might offer some brief dry time with clouds, but rain chances will climb steadily into the afternoon. Meteorologists say the likelihood of rain will spike to 70% by mid to late afternoon, so anyone heading out after lunch should be prepared for drizzle or even steady showers by the evening.
Temperatures on Monday will remain relatively mild, topping out near 68°F, but the combination of clouds and moisture will make the air feel cooler and heavier than it has in recent days.
A Wet Week Ahead for Philly
This isn’t just a one-day event. The rain will stick around well into the workweek, with showers expected daily through at least Friday. Here’s a breakdown of what you can expect:
-
Tuesday: On-and-off showers, especially in the morning, with some drying possible by late afternoon.
-
Wednesday: Possibly the wettest day of the week, with heavier rain expected and chances of localized downpours.
-
Thursday: More showers likely, along with a slight drop in temperature. Highs could dip into the low 60s.
-
Friday: Showers will begin to taper off, but skies may stay cloudy and damp until evening.
So, if you’re hoping for a sunny spring week, it’s time to adjust your plans. Indoor activities will be your best bet, and daily commutes may take longer with wet roads and reduced visibility.
What’s Causing the Rain?
A cold front sweeping down from the Great Lakes is clashing with a warm, moist air mass moving up from the south. This collision of air systems is creating the perfect conditions for several days of rainfall. The system is slow-moving, which is why the showers will be stretched out over multiple days.
While severe weather isn’t expected at this point, some periods of moderate to heavy rainfall are possible, especially midweek. Localized flooding in low-lying areas and poor drainage spots could occur if the rain becomes steady for several hours.
What Should You Do to Prepare?
This isn’t dangerous weather, but it is the kind that can ruin your day if you’re caught off guard. Here’s how to stay one step ahead of the downpours:
-
Carry a compact umbrella or wear a light raincoat
-
Watch for slick streets and slower traffic, especially during commutes
-
Reschedule or rethink outdoor plans for later in the week
-
Keep an eye on weather alerts, especially midweek when heavier rain is forecast
Looking Ahead: Will the Sun Return?
There’s good news for weekend lovers — current forecasts suggest that by late Friday or Saturday, the rain should begin to clear out. Dry air is expected to return, with temperatures rebounding into the low 70s by Sunday. So while the workweek may be gloomy, the weekend looks like a great time to get outside again.
Final Thoughts
Philadelphia is no stranger to spring showers, but this upcoming stretch of five straight rainy days could dampen the spirits of even the most seasoned locals. Still, it’s all part of the season’s shift, and better weather is on the horizon. Just hang tight, keep your boots handy, and check forecasts daily.
