Which radars cover Cotter?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 51 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 Cotter | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 51 mi east-northeast | 3,600 ft | Good — most storms and steady rain or snow show clearly |
| KDMX Des Moines, IA | 121 mi west-northwest | 12,900 ft | Limited — the beam overshoots the lowest part of storms |
| KILX Lincoln, IL | 136 mi southeast | 15,600 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.
