WILMINGTON, Delaware – A cool, clear start greets northern Delaware this Tuesday morning, but it won’t stay calm for long. Clouds are building to the west, hinting at a wet, unsettled stretch on the way before Halloween brings back dry, comfortable conditions.
According to the National Weather Service in Mount Holly, today stays mostly sunny and brisk, with highs near 58°F and gusts up to 25 mph. Skies will cloud over late tonight as a developing coastal system approaches, setting up rain chances for Wednesday and Thursday.
By Wednesday afternoon, showers become more frequent, with breezy northeast winds between 10 and 15 mph. The rain picks up strength Thursday, potentially heavy at times as a cold front sweeps through the Delaware Valley. Totals could approach an inch, especially along the I-95 corridor, with wet pavement and reduced visibility slowing the morning commute.
The pattern shifts just in time for Halloween. Friday brings sunshine and highs near 59°F, perfect for outdoor events and trick-or-treat plans. Evening temperatures will slip into the 40s under mostly clear skies — crisp, cool, and classic for late October.
The weekend stays quiet, with Saturday and Sunday both mostly sunny and mild. It’s prime weather for leaf cleanup or early holiday decorating before a chillier trend builds in next week. Models hint at cooler air pushing south as November begins — a reminder that early-winter patterns are already forming across the Mid-Atlantic.
