Which radars cover Mascot?
The closest NEXRAD Doppler radar is KMRX (Knoxville, TN), about 21 miles east-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 Mascot | View |
|---|---|---|---|
| KMRX Knoxville, TN | 21 mi east-northeast | 1,200 ft | Excellent — the lowest scan sees close to the ground |
| KJKL Jackson, KY | 108 mi north-northeast | 10,800 ft | Limited — the beam overshoots the lowest part of storms |
| KGSP Greer, SC | 119 mi southeast | 12,600 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.
