Which radars cover Charlotte Hall?
The closest NEXRAD Doppler radar is KLWX (Sterling, MD), about 52 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 Charlotte Hall | View |
|---|---|---|---|
| KLWX Sterling, MD | 52 mi northwest | 3,700 ft | Good — most storms and steady rain or snow show clearly |
| KDOX Dover AFB, DE | 77 mi east-northeast | 6,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KAKQ Wakefield, VA | 103 mi south | 10,100 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.
