Which radars cover Banner Hill?
The closest NEXRAD Doppler radar is KMRX (Knoxville, TN), about 55 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 Banner Hill | View |
|---|---|---|---|
| KMRX Knoxville, TN | 55 mi west | 4,000 ft | Good — most storms and steady rain or snow show clearly |
| KGSP Greer, SC | 86 mi south | 7,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KJKL Jackson, KY | 113 mi north-northwest | 11,600 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.
