Which radars cover Coalmont?
The closest NEXRAD Doppler radar is KHTX (Huntsville, AL), about 35 miles 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 Coalmont | View |
|---|---|---|---|
| KHTX Huntsville, AL | 35 mi southwest | 2,300 ft | Excellent — the lowest scan sees close to the ground |
| KOHX Nashville, TN | 78 mi northwest | 6,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KHPX Fort Campbell, KY | 130 mi northwest | 14,500 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.
