| Radar | Distance | Lowest beam over Walker Mill | View |
|---|---|---|---|
| KLWX Sterling, MD | 33 mi west-northwest | 2,100 ft | Excellent — the lowest scan sees close to the ground |
| KDOX Dover AFB, DE | 78 mi east | 6,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KAKQ Wakefield, VA | 131 mi south | 14,600 ft | Limited — the beam overshoots the lowest part of storms |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
