Wilmington, Delaware – Heat and humidity will peak across Delaware Sunday with highs near 91°F, but attention is already turning to the next round of storms.
According to the National Weather Service in Mount Holly, a chance of showers and thunderstorms returns Monday afternoon, mainly after 2 p.m. in Wilmington. The risk intensifies into Monday night, with new rainfall totals generally under a tenth of an inch, although locally heavier downpours are possible during thunderstorms.
Travelers along I-95 and local roadways should plan for potential delays Monday evening, especially during the evening commute. While Sunday remains hot and sunny with light winds, the build-up of moisture and rising dewpoints will fuel instability across New Castle County. Those spending time outdoors should stay hydrated and monitor conditions into Monday.
