Which radars cover Greeneville?
The closest NEXRAD Doppler radar is KMRX (Knoxville, TN), about 32 miles west. 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 Greeneville | View |
|---|---|---|---|
| KMRX Knoxville, TN | 32 mi west | 2,000 ft | Excellent — the lowest scan sees close to the ground |
| KGSP Greer, SC | 95 mi south-southeast | 8,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KJKL Jackson, KY | 102 mi north-northwest | 9,900 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.
