Which radars cover Mason Neck?
The closest NEXRAD Doppler radar is KLWX (Sterling, MD), about 28 miles northwest. Radar beams climb as they travel, so the height of the lowest scan over town decides how low in a storm the radar can see.
| Radar | Distance | Lowest beam over Mason Neck | View |
|---|---|---|---|
| KLWX Sterling, MD | 28 mi northwest | 1,700 ft | Excellent — the lowest scan sees close to the ground |
| KDOX Dover AFB, DE | 94 mi east | 8,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KAKQ Wakefield, VA | 116 mi south | 12,000 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.
