Seven-day outlook
44–73°F across the weekThe week runs between 45° and 73°, with tomorrow the warmest day of it. There is no real trend across it: one day looks much like the next. Every day in the outlook stays dry.
Forecasts come from the National Weather Service's own computer models, and current conditions from the nearest reporting weather station. Both are served through the weather API. A forecast is guidance, not a warning, and anything the Weather Service has actually issued is on the live map.
The written summaries on this page are generated from the forecast data above, not by a meteorologist. Each sentence is a reading of the same numbers you can see, and no forecaster has reviewed them.

How well can the network see Selbyville?
The nearest Doppler radar is KDOX (Dover AFB, DE), 28 miles to the NNW. A WSR-88D's lowest routine scan sits half a degree above horizontal, and the earth curves away beneath it, so by the time that beam reaches Selbyville its center is about 1,700 ft above ground. That is about as close as radar coverage gets in the United States: the lowest scan is still near the ground when it reaches Selbyville, so low-level rotation and the leading edge of a gust front show up on it. Selbyville is closer to its radar than 74% of US cities.
The closest instrument actually measuring the air is KOXB · Ocean City Muni on the ASOS/AWOS network, 12 miles away. Near enough to be representative on most days, though a summer thunderstorm can soak one and miss the other entirely.
Beam height is the standard 4/3-earth approximation for the 0.5° scan and assumes normal refraction; it is where the center of the beam is, not its edges, and unusual temperature profiles bend it. Radar siting from the NWS WSR-88D network, station positions from the Delaware observing network as of this build.
