Which radars cover Rocky Top?
The closest NEXRAD Doppler radar is KMRX (Knoxville, TN), about 42 miles east. 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 Rocky Top | View |
|---|---|---|---|
| KMRX Knoxville, TN | 42 mi east | 2,800 ft | Excellent — the lowest scan sees close to the ground |
| KJKL Jackson, KY | 105 mi north-northeast | 10,400 ft | Limited — the beam overshoots the lowest part of storms |
| KOHX Nashville, TN | 134 mi west | 15,200 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.
