Which radars cover Maryville?
The closest NEXRAD Doppler radar is KMRX (Knoxville, TN), about 43 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 Maryville | View |
|---|---|---|---|
| KMRX Knoxville, TN | 43 mi northeast | 2,900 ft | Excellent — the lowest scan sees close to the ground |
| KGSP Greer, SC | 116 mi east-southeast | 12,000 ft | Limited — the beam overshoots the lowest part of storms |
| KHTX Huntsville, AL | 131 mi west-southwest | 14,700 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.
