How well can the network see Sinking Spring?
The nearest Doppler radar is KDIX (Philadelphia, PA), 89 miles to the ESE. 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 Sinking Spring its center is about 8,100 ft above ground. At that range the beam overshoots the layer where severe weather organizes. The radar is describing the middle of the storm, not its base , which is why a warning for Sinking Spring can look unsupported on the mosaic and still be right. Trust the warning over the picture.
The closest instrument actually measuring the air is KRDG · Reading/Spaatz Fld on the ASOS/AWOS network, 4.7 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 Pennsylvania observing network as of this build.
