Which radars cover Knoxville?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 51 miles north-northwest. 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 Knoxville | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 51 mi north-northwest | 3,700 ft | Good — most storms and steady rain or snow show clearly |
| KILX Lincoln, IL | 72 mi southeast | 5,900 ft | Good — most storms and steady rain or snow show clearly |
| KLOT Chicago, IL | 124 mi east-northeast | 13,400 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.
