Which radars cover Garrison?
The closest NEXRAD Doppler radar is KLWX (Sterling, MD), about 49 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 Garrison | View |
|---|---|---|---|
| KLWX Sterling, MD | 49 mi southwest | 3,500 ft | Good — most storms and steady rain or snow show clearly |
| KDOX Dover AFB, DE | 81 mi east-southeast | 7,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCCX State College, PA | 124 mi north-northwest | 13,400 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.
