Which radars cover Glen Rock?
The closest NEXRAD Doppler radar is KLWX (Sterling, MD), about 69 miles southwest. 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 Glen Rock | View |
|---|---|---|---|
| KLWX Sterling, MD | 69 mi southwest | 5,600 ft | Good — most storms and steady rain or snow show clearly |
| KDOX Dover AFB, DE | 96 mi southeast | 9,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCCX State College, PA | 103 mi northwest | 10,000 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.
