Delaware wakes under a dim, chilly sky as early light spreads across Wilmington, glinting off cold pavement and quiet neighborhoods. The crisp air sets the stage for a December Weather Alert, with a stronger coastal system expected to reach the region by Tuesday, bringing rain, a brief snow chance, and slowed travel for those returning to routine after the holiday week.
According to the National Weather Service, today turns cloudy with afternoon rain and highs near 46. Monday brings calmer air and increasing clouds, marking the early sign of Tuesday’s more impactful system. Meteorologists now track a surge of colder air sliding toward northern Delaware just as precipitation deepens, raising a limited but notable rain–snow mix chance from mid-morning to early afternoon.
Accumulation looks light—generally less than one inch, and most surfaces stay too warm to hold much snow—but quick bursts may still reduce visibility on I-95, Route 141, and Concord Pike. Commuters should plan extra time, especially around lunchtime, when the potential changeover may be most noticeable.
By Tuesday afternoon, the system transitions back to steady rain as warmer air returns. Winds increase from the northwest Tuesday night, dropping temperatures into the upper 20s. Any lingering moisture on shaded roads or bridges could freeze, elevating flash-freeze risks even without major snow accumulation. To be fair, models differ on how long early flurries may last, but all show a fast-moving system capable of sharp temperature swings.
Wednesday turns sunny but brisk, offering a clearer break as the region prepares for a colder, early-winter stretch heading into the first week of December.
