Philadelphia woke up to a soggy start on Wednesday, April 22, 2026, as a weak area of low pressure slid through with light rain, mid to upper 40s, and broken clouds overhead. The main wet window is the morning commute, with showers expected to ease by midday before a noticeably warmer, brighter Thursday moves in.
Morning Showers and the Commute
Scattered to likely showers are on tap through late morning, with the best shot at rain roughly between 9 a.m. and noon. Totals look light, on the order of about a tenth to a quarter of an inch. Southeast winds around 5 to 10 mph early will turn southwest as the day goes on, and some patchy fog could hang around from overnight into the early commute.
Out on the water, the National Weather Service Mount Holly keeps Small Craft Advisories in play across the Delaware Bay and nearby Atlantic waters through the morning and early afternoon. Boaters can expect 2 to 4 foot seas and occasionally gusty conditions, so it is not the friendliest morning for a casual run.
Warm Thursday, Cooler By Friday
By Thursday, high pressure muscles in, bringing sunshine and afternoon highs near 75°F. It will feel like a different season compared with the soggy start to Wednesday. That warmup does not last long, though: a backdoor cool front is poised to slip through on Friday, knocking temperatures back and bringing the chance of spotty showers.
The quick swing comes on the heels of this week's overnight freeze and rapid rebound.

Timing of the cool push is touchy, so inland and higher-terrain spots may feel the chill again a bit earlier than Center City.
Weekend Outlook
Looking ahead, low pressure is forecast to organize over the Great Lakes and swing toward the region on Saturday. That system brings a broader shield of rain, with a raw high only in the 40s to near 50°F and widespread rainfall totals around one half inch possible. Showers should taper Saturday night, but a few could linger into Sunday before conditions dry out and warm up to start next week.
If your weekend plans involve time outside, plan for a chilly, wet stretch and keep the rain gear close. It will not be a washout from start to finish, but it will feel every bit like a late April reality check.
