Which radars cover Marietta?
The closest NEXRAD Doppler radar is KLWX (Sterling, MD), about 90 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 Marietta | View |
|---|---|---|---|
| KLWX Sterling, MD | 90 mi southwest | 8,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCCX State College, PA | 97 mi northwest | 9,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDOX Dover AFB, DE | 104 mi southeast | 10,200 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.
