Philadelphia, Pennsylvania – Dry roads and sunshine today will give way to a soaking midweek system, with rain arriving late Wednesday night and potentially disrupting the Thursday morning commute across the region.
According to the National Weather Service in Mount Holly, conditions will remain sunny and seasonable through Monday, with only a few light showers possible late Tuesday. A stronger system develops Wednesday afternoon, bringing more widespread rain into the evening and overnight hours.
Rainfall totals between 0.50 and 1.00 inch are expected across eastern Pennsylvania, New Jersey, and Delaware, including Philadelphia, Allentown, Trenton, and Wilmington. The heaviest rain is likely overnight Wednesday into early Thursday, creating slick conditions on major roadways such as I-95, I-76, the New Jersey Turnpike, and Route 1.
Drivers should prepare for reduced visibility and ponding on roads during heavier downpours, especially during the Thursday morning commute window. While severe weather is not expected, steady rainfall could slow traffic and impact transit schedules.
Dry weather holds through Tuesday before conditions deteriorate late Wednesday. Additional updates are expected within the next 24 to 48 hours as the timing and rainfall amounts become more precise.
