Which radars cover Clemons?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 39 miles southwest. 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 Clemons | View |
|---|---|---|---|
| KDMX Des Moines, IA | 39 mi southwest | 2,600 ft | Excellent — the lowest scan sees close to the ground |
| KDVN Quad Cities, IA | 137 mi east-southeast | 15,700 ft | Limited — the beam overshoots the lowest part of storms |
| KARX La Crosse, WI | 154 mi northeast | 19,000 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.
