Delaware – Heavy, glittering flakes sweep across Wilmington this morning, stacking quickly on cars, lawns, and neighborhood streets. Drivers rolling out early feel the tires slip on slick, compacted snow—a clear sign that winter has arrived as the week before Christmas accelerates.
According to the National Weather Service, a Winter Weather Advisory remains in effect until 1 p.m., with 3 to 5 inches expected across northern Delaware, northern and northwest New Jersey, and southeast Pennsylvania. Snow remains steady through late morning before easing into scattered showers. Gusty northwest winds, rising to 20 mph with gusts near 35 mph, may whip loose snow back across roadways, especially along I-95, Route 202, and the Christina corridor.
Meteorologists warn that temperatures fall sharply through the afternoon as arctic air surges in. Slush left on untreated streets may flash-freeze, forming hard, invisible sheets of ice—one of the most dangerous early-winter travel hazards. Plan extra time for midday errands and brace for limited visibility during heavier showers.
Monday brings increasing clouds and a high near 36°, but wind chills hover in the teens. Even as conditions dry, leftover snowpack may crust and refreeze overnight, especially in shaded neighborhoods. To be fair, winds relax Monday night, yet the cold lingers long enough to make early commutes feel sharp and biting.
By Tuesday, skies turn mostly sunny with highs near 33°. Still, the morning opens with light frost and slick patches where refreezing occurred—an early-season reminder that December travel demands caution.
