Which radars cover Hudson?
The closest NEXRAD Doppler radar is KBOX (Boston, MA), about 37 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 Hudson | View |
|---|---|---|---|
| KBOX Boston, MA | 37 mi southeast | 2,400 ft | Excellent — the lowest scan sees close to the ground |
| KGYX Portland, ME | 123 mi north-northeast | 13,200 ft | Limited — the beam overshoots the lowest part of storms |
| KOKX Upton, NY | 125 mi south-southwest | 13,600 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.
