Delaware – Dense fog and damp air are slowing traffic along I-95 and I-495, where visibility drops near 3 miles and headlights glow through the haze. Temperatures are climbing fast toward the upper 70s, setting up a sharp swing from spring warmth to soaking rain by late weekend.
According to the National Weather Service, widespread fog clears by late morning, giving way to mostly sunny skies and highs near 77°F. Light winds shift southwest, pulling in warmer air and increasing moisture ahead of an unsettled pattern.
Across Wilmington and nearby corridors like Route 13 and I-295, conditions stay warm into Saturday with highs reaching 82°F. A 40% chance of showers and thunderstorms develops after 2 p.m., bringing brief downpours that could slick roads quickly. Drivers should stay alert for sudden visibility drops during heavier bursts.
Rain intensifies late Saturday night and becomes widespread Sunday, with a 100% chance of steady showers and highs near 72°F. That rainfall could create ponding on I-95 and slow travel across the Delaware Valley during the evening commute. Plan extra time and avoid low-lying roads prone to flooding.
Showers taper Sunday night, followed by a cooler, calmer pattern Monday with sunshine and highs near 56°F. Overnight lows fall into the 30s early next week, raising the risk of patchy slick spots if surfaces remain wet .
