Which radars cover Lake Tansi?
The closest NEXRAD Doppler radar is KHTX (Huntsville, AL), about 87 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 Lake Tansi | View |
|---|---|---|---|
| KHTX Huntsville, AL | 87 mi southwest | 7,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KOHX Nashville, TN | 88 mi west-northwest | 7,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMRX Knoxville, TN | 95 mi east-northeast | 8,900 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.
