Which radars cover South Lancaster?
The closest NEXRAD Doppler radar is KBOX (Boston, MA), about 44 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 South Lancaster | View |
|---|---|---|---|
| KBOX Boston, MA | 44 mi southeast | 3,000 ft | Good — most storms and steady rain or snow show clearly |
| KENX Albany, NY | 121 mi west | 12,900 ft | Limited — the beam overshoots the lowest part of storms |
| KGYX Portland, ME | 124 mi northeast | 13,400 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.
