Wilmington, Delaware — A late-season cold surge will move into Delaware early Friday, May 8, bringing near-freezing overnight temperatures, gusty winds, and periods of rain that could disrupt travel and outdoor activity across Wilmington, Dover, Newark, Middletown, and Rehoboth Beach.
According to NOAA’s Climate Prediction Center, temperatures will run 50–60% below normal through May 14, with the coldest air settling in Friday night. The most critical window is from 2 a.m. to 7 a.m. Saturday, when temperatures are expected to drop into the low 30s across inland areas and near the mid-30s along the coast.
That cold will create immediate impacts. Frost could form on bridges and overpasses along I-95 and Route 1, leading to slick spots for early morning drivers. Inland areas like Dover and Newark may see colder pockets that increase the risk of plant damage and expose early-shift workers to near-freezing conditions.
Rain arriving Friday night will reduce visibility and create water pooling on roads. Low-lying roads near the Christina River in Wilmington and flood-prone intersections in Dover could see rapid runoff and standing water within minutes during heavier showers.
Winds will strengthen Saturday into Sunday, with gusts reaching 30 to 35 mph, especially along the coast near Rehoboth Beach. Those winds may bring down small branches and cause isolated power outages.
Drivers should slow down on wet or slick roads, particularly before sunrise when frost may develop, and avoid water-covered roadways. Residents should cover sensitive plants and secure outdoor items ahead of the wind.
The highest risk for freezing temperatures and travel disruptions peaks early Saturday between 2 a.m. and 7 a.m.
