Which radars cover Charlestown?
The closest NEXRAD Doppler radar is KENX (Albany, NY), about 94 miles west-southwest. 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 Charlestown | View |
|---|---|---|---|
| KENX Albany, NY | 94 mi west-southwest | 8,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCXX Burlington, VT | 96 mi north-northwest | 9,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KBOX Boston, MA | 110 mi southeast | 11,100 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.
