Which radars cover Marlborough?
The closest NEXRAD Doppler radar is KBOX (Boston, MA), about 85 miles 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 Marlborough | View |
|---|---|---|---|
| KBOX Boston, MA | 85 mi southeast | 7,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KENX Albany, NY | 97 mi west-southwest | 9,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGYX Portland, ME | 120 mi northeast | 12,600 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.
