Wilmington, Delaware – A mid-February warm-up is expected across Delaware, with temperatures forecast to run 10 to 20 degrees above normal from Feb. 16–20, according to the NOAA Climate Prediction Center.
The Climate Prediction Center’s 6–10 day temperature outlook shows a strong signal for above-normal temperatures statewide, including Wilmington and Dover. Probabilities for warmer-than-average conditions exceed 60 percent, indicating a high-confidence shift away from typical winter weather.
Under normal conditions, mid-February highs across Delaware generally range from the upper 30s to lower 40s. During this warm stretch, daytime temperatures are expected to climb into the upper 40s and 50s, with some inland and southern locations potentially reaching the lower 60s during peak warmth.
This warming trend is part of a broader weather pattern affecting much of the central and eastern United States. While the most dramatic warmth—highs in the 50s and 60s—is expected across the Midwest and Mississippi Valley, the Mid-Atlantic is still likely to experience a noticeable but temporary break from winter cold, often described as a “spring tease.”
Precipitation outlooks indicate near to slightly above-normal rainfall potential during this period. Combined with rising temperatures, this may lead to accelerated runoff, increasing the risk for localized ponding, river rises, and minor flooding in low-lying and poor drainage areas.
Forecasters stress that this outlook reflects probabilistic climate guidance, not a day-to-day forecast. Colder air can still return later in February, and residents are encouraged to monitor local forecasts for updated details.
For commuters, students, and outdoor workers, the milder stretch may offer brief relief from winter conditions, though rapidly changing weather remains possible.
