Which radars cover Antrim?
The closest NEXRAD Doppler radar is KBOX (Boston, MA), about 86 miles south-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 Antrim | View |
|---|---|---|---|
| KBOX Boston, MA | 86 mi south-southeast | 7,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGYX Portland, ME | 103 mi northeast | 10,100 ft | Limited — the beam overshoots the lowest part of storms |
| KENX Albany, NY | 112 mi west-southwest | 11,400 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.
