Which radars cover Seymour?
The closest NEXRAD Doppler radar is KMRX (Knoxville, TN), about 28 miles northeast. 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 Seymour | View |
|---|---|---|---|
| KMRX Knoxville, TN | 28 mi northeast | 1,700 ft | Excellent — the lowest scan sees close to the ground |
| KGSP Greer, SC | 111 mi southeast | 11,300 ft | Limited — the beam overshoots the lowest part of storms |
| KJKL Jackson, KY | 121 mi north-northeast | 12,800 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.
