Philadelphia woke up under a gray lid on Thursday morning, April 2, with temperatures stuck in the upper 40s and an easterly breeze of about 10–15 mph keeping things feeling extra raw. A few light rain showers could sneak through late in the morning, and highs are only headed for around 50°F, so a jacket is non‑negotiable for the commute, as per the National Weather Service.
Morning Commute
Roads and sidewalks should stay just damp rather than drenched, but drivers and pedestrians may run into isolated pockets of drizzle or brief light showers between about 8 a.m. and late morning. East winds of 10–15 mph, with gusts near 20 mph along the river and the Delaware shore, will keep it feeling cooler than the thermometer suggests, according to the National Weather Service.
Thursday Night Into Friday
As Thursday night gives way to early Friday, April 3, there is a slight chance of late showers before low clouds and patchy fog move in, with lows near 42°F. The National Weather Service notes that ceilings could drop to IFR and visibility may fall in fog, which can tangle up early‑morning flights and the Friday commute. Conditions are expected to improve after a warm front lifts through Friday morning, setting the stage for a sharp jump in temperatures.
Warm Weekend Ahead
Once that warm front moves through on Friday, April 3, highs are projected to leap into the mid 70s, around 76°F. Saturday, April 4, is on track to be the warmest of the stretch, with many spots likely reaching the low 80s. A cold front follows on Sunday, April 5, bringing rounds of showers and a chance of thunderstorms before more typical, cooler April air returns on Monday, April 6. Forecasters with the National Weather Service are flagging the weekend timing and the potential for multiple rounds of rain late Sunday.
Boaters and Flights
A Small Craft Advisory is posted for the northern and central Atlantic coastal waters through midnight Thursday, with seas building to 4–6 feet and northeast winds gusting into the 20s. Another round of Small Craft Advisory conditions looks likely Friday afternoon and into the weekend, and Sunday may feature briefly stronger winds offshore, according to the National Weather Service. Mariners should plan around those choppy conditions, and air travelers should be ready for low ceilings and patchy fog Thursday night that could affect early Friday flights.
