Philadelphia, Pennsylvania – A developing coastal system could disrupt travel on I-95 and the Schuylkill Expressway by late Sunday night, with up to 6 inches of snow possible before the Monday morning commute.
According to the National Weather Service in Mount Holly, a low pressure system tracking near the Mid-Atlantic coast Sunday into Monday may bring accumulating snow, gusty winds and potential tidal flooding. Current projections show a 30 to 40 percent probability of at least 6 inches of snow in and around Philadelphia, with higher odds exceeding 2 inches across southeastern Pennsylvania and southern New Jersey. Snow could begin after 8 p.m. Sunday and continue through early Monday.
Two primary scenarios remain in play. A track closer to the coast would increase snowfall totals, strengthen winds to near 40 mph along I-95 and I-295, and raise the risk of tidal flooding along the Delaware River and coastal New Jersey. A farther offshore track would still bring light to moderate snow but with lower wind speeds and less widespread flooding.
Road conditions may deteriorate quickly overnight Sunday, especially on elevated stretches of I-76, I-476 and US-1. Visibility could drop below one mile during steadier bands. SEPTA riders and Monday commuters should monitor updates for potential delays.
Residents should prepare now by checking emergency kits, charging devices and allowing extra travel time Monday morning. Forecast confidence will increase over the next 24 to 36 hours, and winter weather headlines may be issued as the storm track becomes clearer.
