Wilmington, DE – The first rays of December sun glint off car hoods this morning as Delaware braces for another weather shift later this week. After a calm start, meteorologists say a midweek storm system will bring rain Wednesday, followed by a chance of snow Thursday night as colder air rushes back into the region.
According to the National Weather Service in Mount Holly, Wednesday’s highs will reach near 48°F, warm enough for rain during most of the day. By Thursday night, however, the system’s trailing edge will meet falling temperatures near 29°F, setting the stage for a rain-to-snow mix that could briefly coat grassy areas and bridges. The 40% chance of precipitation comes as part of a developing cold snap stretching across the Mid-Atlantic and into New England.
Drivers should stay alert for slippery roads Thursday night and early Friday, especially in northern Delaware and along I-95 where freezing air often lingers in shaded stretches. “Even light snow can create hazardous travel when temperatures hover near freezing,” forecasters cautioned.
Friday brings partial clearing and colder air, with highs near 38°F and brisk northwest winds signaling winter’s return. The weekend looks chilly but mostly dry — ideal for holiday decorating or travel ahead of the mid-December freeze expected across much of the East.
Meteorologists continue to watch Dec. 11–17 for a potential Arctic blast and renewed snow chances across the Great Lakes, Ohio Valley, and Northeast — a signal that true winter is on the move.
