Which radars cover Madisonville?
The closest NEXRAD Doppler radar is KMRX (Knoxville, TN), about 70 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 Madisonville | View |
|---|---|---|---|
| KMRX Knoxville, TN | 70 mi northeast | 5,700 ft | Good — most storms and steady rain or snow show clearly |
