Which radars cover Lisbon?
The closest NEXRAD Doppler radar is KLWX (Sterling, MD), about 33 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 Lisbon | View |
|---|---|---|---|
| KLWX Sterling, MD | 33 mi southwest | 2,100 ft | Excellent — the lowest scan sees close to the ground |
| KDOX Dover AFB, DE | 94 mi east-southeast | 8,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCCX State College, PA | 120 mi north-northwest | 12,800 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.
