Delaware – Cold air presses in early this morning as gray clouds hang low over the Christina River and exhaust lingers above quiet streets. Winter conditions remain firmly in place across northern Delaware, with a stretch of cold nights, refreezing, and two snow chances lining up before the weekend.

According to the National Weather Service, temperatures remain below normal through late week. Highs reach the lower to mid-30s, while nighttime lows drop into the teens and single digits. Calm winds may ease the bite slightly, but cold pavement remains a concern.

In Wilmington, today turns partly sunny and dry, offering brief relief. That window closes quickly after sunset. Any melting during the afternoon will refreeze fast, increasing the risk of slick spots on bridges, ramps, and untreated side streets. Flash freezing remains a concern during evening travel.

A weak system brings a chance of light snow late this evening into early Wednesday. Accumulations should stay under a half inch, but even light flakes can reduce visibility and traction. I-95, I-495, Route 202, and city arterials may see slick patches during the morning commute.

Conditions improve Wednesday afternoon, but the cold lingers. Thursday stays sunny and brisk, with highs near 28 and another hard freeze after dark. By Friday, clouds thicken again as another system approaches. Snow chances return Friday afternoon into Friday night, with temperatures cold enough for accumulation, though totals appear light for now.

Saturday turns colder and brighter, with highs near 19 and icy spots lingering in shaded areas. Anyone traveling early should plan extra time and use caution.

Looking ahead, 6–10 day outlooks hint at milder air building late next week as warmth expands from the central U.S. Until then, winter hazards persist. Heading out Friday night or Saturday morning? Tell us what road conditions look like where you are.
