Which radars cover Siasconset?
The closest NEXRAD Doppler radar is KBOX (Boston, MA), about 77 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 Siasconset | View |
|---|---|---|---|
| KBOX Boston, MA | 77 mi northwest | 6,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KOKX Upton, NY | 153 mi west | 18,800 ft | Limited — the beam overshoots the lowest part of storms |
| KGYX Portland, ME | 182 mi north | 25,000 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.
