Wilmington, Delaware – Snow will overspread much of Delaware, southern New Jersey, and nearby Pennsylvania overnight, leading to slippery travel conditions through Sunday afternoon as a Winter Weather Advisory remains in effect.
Snow is expected to develop late tonight, with the steadiest period falling between 1 a.m. and mid-morning Sunday. In New Castle County, including Wilmington, totals of 2 to 4 inches are expected by the time snow tapers Sunday afternoon. Farther south across central and southern Delaware, including Dover, Georgetown, Rehoboth Beach, and Ocean City, accumulations are forecast to be up to 3 inches, with lighter totals closer to the immediate coast.
According to the National Weather Service office in Mount Holly, the advisory remains in effect until 1 p.m. Sunday for most of the region. Northwest New Jersey and the Lehigh Valley will see snow end earlier, with advisories expiring around 7 a.m. Sunday, while snow lingers longer across Delaware, southern New Jersey, and southeast Pennsylvania outside the Philadelphia metro.
Road conditions are expected to deteriorate overnight as temperatures remain near or below freezing. Bridges, overpasses, and untreated roads will become slick first, especially during the early Sunday morning travel window. Routes including I-95, I-295, Route 1, Route 13, Route 40, and Route 322 may be impacted by snow-covered lanes and reduced visibility.
DelDOT, PennDOT, and NJDOT crews will be treating major highways, but officials urge drivers to slow down, increase following distance, and allow extra travel time. Anyone heading out early Sunday should be prepared for slippery conditions, particularly on secondary roads and in shaded areas.
Snow will gradually taper late Sunday morning into early afternoon. Even after snowfall ends, lingering slick spots are likely as cold pavement temperatures persist.
