Which radars cover Cornwall?
The closest NEXRAD Doppler radar is KCCX (State College, PA), about 95 miles west-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 Cornwall | View |
|---|---|---|---|
| KCCX State College, PA | 95 mi west-northwest | 8,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLWX Sterling, MD | 106 mi south-southwest | 10,500 ft | Limited — the beam overshoots the lowest part of storms |
| KDIX Philadelphia, NJ | 108 mi east | 10,800 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.
