Which radars cover Sweetwater?
The closest NEXRAD Doppler radar is KMRX (Knoxville, TN), about 72 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 Sweetwater | View |
|---|---|---|---|
| KMRX Knoxville, TN | 72 mi east-northeast | 5,900 ft | Good — most storms and steady rain or snow show clearly |
| KHTX Huntsville, AL | 102 mi west-southwest | 9,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KOHX Nashville, TN | 125 mi west-northwest | 13,600 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.
