Which radars cover Granby?
The closest NEXRAD Doppler radar is KBOX (Boston, MA), about 75 miles east-southeast. 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 Granby | View |
|---|---|---|---|
| KBOX Boston, MA | 75 mi east-southeast | 6,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KENX Albany, NY | 81 mi west-northwest | 7,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KOKX Upton, NY | 98 mi south | 9,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
