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 Ashland?
The nearest Doppler radar is KBOX (Boston, MA), 27 miles to the SE. 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 Ashland its center is about 1,600 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 Ashland, so low-level rotation and the leading edge of a gust front show up on it. Ashland is closer to its radar than 75% of US cities.
The closest instrument actually measuring the air is KOWD · Norwood Mem on the ASOS/AWOS network, 16 miles away. Far enough that "current conditions" for Ashland is an educated reading of somewhere else, worth knowing before you plan around a single temperature.
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 Massachusetts observing network as of this build.
