Which radars cover Lower Allen?
The closest NEXRAD Doppler radar is KCCX (State College, PA), about 75 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 Lower Allen | View |
|---|---|---|---|
| KCCX State College, PA | 75 mi northwest | 6,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLWX Sterling, MD | 92 mi south-southwest | 8,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDOX Dover AFB, DE | 124 mi southeast | 13,500 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.
