Which radars cover Thomaston?
The closest NEXRAD Doppler radar is KGYX (Portland, ME), about 55 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 Thomaston | View |
|---|---|---|---|
| KGYX Portland, ME | 55 mi west-southwest | 4,100 ft | Good — most storms and steady rain or snow show clearly |
| KCBW Caribou, ME | 151 mi north-northeast | 18,300 ft | Limited — the beam overshoots the lowest part of storms |
| KBOX Boston, MA | 177 mi southwest | 23,800 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.
