Pennsylvania – Cold air bites harder this morning as clouds slide over the Delaware Valley, hinting at what’s coming. A significant winter storm is lining up to impact Philadelphia and surrounding areas from Saturday evening into early Monday, bringing heavy snow and a dangerous wintry mix.
Quiet conditions hold through Friday. Sunshine fades behind passing clouds, and temperatures drop sharply Friday night, with lows near 10 degrees. That cold locks into place ahead of incoming moisture. According to the National Weather Service in Mount Holly, a Winter Storm Watch remains in effect for much of southeastern Pennsylvania, central and southern New Jersey, and northern Delaware.
Snow develops Saturday night and quickly becomes steady. Accumulations may turn significant by early Sunday, especially north and west of the city. Roads could become snow-covered in a matter of hours as snowfall rates increase. Winds stay moderate but visibility may drop during heavier bursts.
Sunday brings the highest risk window. Snow may mix with sleet or freezing rain at times, particularly closer to the coast and south of Philadelphia. That mix raises concerns for icy travel and possible power disruptions. Bridges, overpasses, and untreated roads are expected to turn slick early. Flash freezing remains possible if temperatures dip after any brief mixing.
Travel impacts could be severe along I-95, I-76, I-476, and the New Jersey Turnpike. Officials urge drivers to avoid unnecessary travel and prepare for rapidly changing road conditions.
Wintry precipitation may linger into early Monday before tapering. Cold air behind the system keeps icy patches in place for the morning commute. Additional advisories may be issued as confidence in snowfall totals increases.
