Wilmington, Delaware – Afternoon temperatures could climb toward 70°F by Thursday in Wilmington, bringing a burst of early spring warmth across Delaware as a broad warm air pattern spreads from the Midwest into the Mid-Atlantic during the first full days of the new season.
According to the National Weather Service Climate Prediction Center, the weather setup developing Wednesday through Sunday, March 18–22, favors above-normal temperatures across much of the Mid-Atlantic, including Delaware. Many locations may see highs running 15 to 20 degrees above typical mid-March averages.
Cities across northern Delaware including Wilmington and Newark could see daytime highs reaching the upper 60s to near 70°F during the warmest afternoons late in the week. Central communities such as Dover and Smyrna may see temperatures climbing into the mid to upper 60s under mostly sunny skies.
Farther south along the coast, Rehoboth Beach and Lewes could experience slightly cooler conditions with highs in the low to mid-60s, influenced by cooler air near the Atlantic Ocean.
The warming trend will develop alongside limited precipitation chances, with climate outlooks indicating below-normal rainfall probabilities across much of the Mid-Atlantic during this period.
Wind may increase at times along major travel routes including Interstate 95 and U.S. Route 13, with occasional gusts between 20 and 30 mph possible.
While Delaware warms noticeably, the most extreme heat remains farther west where parts of California, Nevada and Arizona could approach 100°F during the same timeframe.
Forecasters say the mild spring pattern may continue through the weekend before broader atmospheric changes begin shifting conditions across the eastern United States early next week.
