Delaware – Headlights fade into a gray blur this morning as dense fog hugs roadways across northern Delaware, dampening sound and shrinking visibility just as traffic builds. Moist air sits heavy along the Christina and Delaware rivers, turning routine drives into cautious crawls.
According to the National Weather Service office in Mount Holly, a Dense Fog Advisory remains in effect through midmorning. Visibility drops to between one quarter and one half mile across much of New Castle County, including Wilmington and surrounding communities. Drivers may encounter rapidly changing conditions, especially near waterways, low spots, and major routes like I-95 and Route 202.
Fog begins thinning later this morning as winds increase and clouds lift. Sunshine breaks through by midday, pushing temperatures into the low 50s. Roads improve, but lingering moisture remains on untreated surfaces. To be fair, that dampness matters once colder air returns later.
Tonight turns cooler and calmer. By Thursday, skies stay mostly sunny with highs near 50, offering a brief stretch of quiet winter weather. Attention then shifts to Friday as rain chances rise with an approaching system. Showers increase later in the day and may affect afternoon and evening travel.
The weekend trends mild but unsettled. Periods of rain are likely Saturday into Saturday night, with slick roads returning. As temperatures drop after dark, pockets of standing water could refreeze, raising the risk of black ice on bridges and ramps.
Slow down during the fog this morning and keep headlights on low beam. Plan extra time for travel through Friday. Meteorologists continue tracking developing systems, and additional Weather Alerts may be issued.
