Philadelphia, PA – Skies across the Delaware Valley remain stubbornly overcast this Sunday as a persistent marine layer continues to dominate, keeping temperatures well below average and setting the stage for scattered showers by late afternoon.
According to the National Weather Service in Mount Holly, high pressure anchored in New England is funneling onshore flow into New Jersey, southeastern Pennsylvania, and northern Delaware. That flow is maintaining cloud cover and holding high temperatures in the mid-60s to low 70s — nearly 10 degrees below seasonal norms. Bethany Beach was only expected to reach 68°F today.
Spotty drizzle has been reported along the coast, with heavier showers and a few thunderstorms likely to form later today as a low-pressure system approaches from the west. Areas including Trenton, Cherry Hill, and Wilmington may see rain develop after 3 p.m., with isolated rumbles of thunder possible through this evening.
Drivers should allow extra time on wet roads, particularly on I-95, the Atlantic City Expressway, and Route 1. Residents should secure outdoor furniture and stay weather-aware in case of thunderstorm warnings.
Unsettled weather is expected to ease overnight, with gradual clearing Monday and a warm-up heading into midweek.
