Which radars cover South Deerfield?
The closest NEXRAD Doppler radar is KENX (Albany, NY), about 75 miles west. 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 Deerfield | View |
|---|---|---|---|
| KENX Albany, NY | 75 mi west | 6,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |

| KOKX Upton, NY | 113 mi south | 11,500 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.
