Which radars cover Calhoun?
The closest NEXRAD Doppler radar is KHTX (Huntsville, AL), about 80 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 Calhoun | View |
|---|---|---|---|
| KHTX Huntsville, AL | 80 mi west-southwest | 6,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMRX Knoxville, TN | 96 mi northeast | 9,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KOHX Nashville, TN | 121 mi west-northwest | 12,900 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.
