Which radars cover Lenoir City?
The closest NEXRAD Doppler radar is KMRX (Knoxville, TN), about 55 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 Lenoir City | View |
|---|---|---|---|
| KMRX Knoxville, TN | 55 mi east-northeast | 4,000 ft | Good — most storms and steady rain or snow show clearly |
| KHTX Huntsville, AL | 118 mi west-southwest | 12,500 ft | Limited — the beam overshoots the lowest part of storms |
