Wilmington, Delaware – Arctic air is expected to remain a persistent influence across Delaware from Jan. 24 through Jan. 30, keeping temperatures below normal and reinforcing mid-winter conditions across the First State.
According to the National Weather Service Climate Prediction Center, Delaware falls within a roughly 60 percent probability zone for below-normal temperatures during the Jan. 24–30 period. While the cold signal is weaker than farther north, confidence remains moderate that sustained chill will linger with limited opportunities for meaningful warm-ups before the end of the month.
Across northern Delaware, including Wilmington and the Interstate 95 corridor, daytime highs are expected to run below late-January averages, with overnight lows frequently dropping into the teens and lower 20s. Persistent cold will allow icy patches to linger on bridges, overpasses, and untreated roads, particularly during early morning and nighttime hours.
In central and southern Delaware, including Dover and communities along U.S. Route 13, temperatures are also expected to stay below normal throughout the Jan. 24–30 window. Coastal influence near Sussex County may slightly temper the coldest nights, but daytime highs are still expected to remain below average, limiting snowmelt and increasing refreeze potential.
Delaware transportation and emergency management officials urge residents to take cold-weather precautions, including protecting exposed pipes, limiting prolonged outdoor exposure, and checking on vulnerable neighbors and pets.
While confidence is moderate, the broader Arctic pattern shows limited signs of breaking before month’s end, keeping below-normal temperatures favored across Delaware through Jan. 30.
