Which radars cover Cornwall?
The closest NEXRAD Doppler radar is KENX (Albany, NY), about 63 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 Cornwall | View |
|---|---|---|---|
| KENX Albany, NY | 63 mi northwest | 4,900 ft | Good — most storms and steady rain or snow show clearly |
| KOKX Upton, NY | 72 mi south-southeast | 5,900 ft | Good — most storms and steady rain or snow show clearly |
| KBOX Boston, MA | 113 mi east | 11,600 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.
