Wilmington, Delaware – A shift toward colder weather during the Jan 20–24 period is increasing concern for snow across Delaware, particularly if storm systems move through while colder air is in place. While temperatures are not expected to be extreme, the trend toward below-normal readings raises the chance that precipitation could fall as snow instead of rain at times.
According to the National Weather Service Climate Prediction Center, Delaware carries a 50–60% probability of below-normal temperatures during the January 20–24 window. Precipitation probabilities remain above normal at 40–50%, a setup that supports snow potential, especially during overnight and early morning hours when colder air is more firmly established.
In Wilmington and northern Delaware, nighttime temperatures are expected to dip below freezing on multiple occasions, increasing the likelihood that snow could accumulate if precipitation develops. Central and southern portions of the state, including Dover and areas along Route 1, may see more marginal conditions, though snow remains possible if colder air deepens during active weather periods. Coastal communities could see changing precipitation types depending on storm timing and wind direction.
Major travel corridors such as I-95, Route 1, Route 13, and Route 202 could become slick during snow periods, particularly during the morning commute. Cold pavement temperatures may allow snow or ice to linger on untreated roads, bridges, and overpasses, even after precipitation tapers off.
Residents are encouraged to prepare ahead of the Jan 20–24 window by monitoring updated weather information, checking heating systems, and ensuring vehicles are winter-ready. While significant snow is not guaranteed, the evolving pattern supports the possibility of at least one impactful winter weather event.
This cooler pattern is expected to persist through late week, and additional advisories or alerts may be issued as confidence in timing and impacts increases.
