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.

How well can the network see Westminster?
The nearest Doppler radar is KLWX (Sterling, VA), 49 miles to the SSW. 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 Westminster its center is about 3,400 ft above ground. That is comfortably inside the useful range. The lowest scan passes low enough over Westminster to show rotation in the part of a storm where tornadoes actually form.
The closest instrument actually measuring the air is KDMW · Westminster/Carroll Cnty Rgnl on the ASOS/AWOS network, 2.1 miles away. Close enough that its readings are, for practical purposes, the conditions in town.
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 Maryland observing network as of this build.
