How well can the network see Sedro-Woolley?
The nearest Doppler radar is KATX (Seattle/Tacoma, WA), 25 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 Sedro-Woolley its center is about 1,500 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 Sedro-Woolley, so low-level rotation and the leading edge of a gust front show up on it. Sedro-Woolley is closer to its radar than 78% of US cities.
The closest instrument actually measuring the air is KBVS · Burlington/Skagit Rgnl on the ASOS/AWOS network, 9.0 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 Washington observing network as of this build.
