Which radars cover Thomaston?
The closest NEXRAD Doppler radar is KOKX (Upton, NY), about 57 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 Thomaston | View |
|---|---|---|---|
| KOKX Upton, NY | 57 mi south-southeast | 4,300 ft | Good — most storms and steady rain or snow show clearly |
| KENX Albany, NY | 80 mi northwest | 6,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KBOX Boston, MA | 102 mi east-northeast | 9,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
