WILMINGTON, Del. – Delaware wakes under calm skies and a cool 52°F this early Sunday, but don’t let the quiet air fool you. A fast-moving storm system will bring a quick punch of fall rain, gusty winds, and wet roads by late tonight — the first sign of a pattern shift across the Mid-Atlantic.
According to the National Weather Service in Mount Holly, widespread showers and a few embedded thunderstorms are expected after 10 p.m., especially along I-95 from Newark to Claymont. South winds between 15 and 20 mph will strengthen through the evening, gusting as high as 30 mph. Rainfall totals may reach up to half an inch before tapering early Monday, with slick pavement and scattered ponding during the morning commute.
Monday will stay breezy but drier, with passing clouds and highs near 64°F. The lingering wind will make it feel cooler, though sunshine begins to reassert itself by Tuesday. That day marks a return to fall calm — clear skies, mild highs near 69°F, and a lighter breeze perfect for outdoor errands or leaf cleanup.
By midweek, cooler air edges back in, dropping highs to the low 60s by Thursday. Nights will turn crisp, dipping into the 40s — the first hint that Delaware’s fall is sliding toward winter’s doorstep. Residents should secure Halloween decorations and outdoor furniture today, as gusty conditions may scatter loose items before the storm clears.
