Which radars cover Dunkerton?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 99 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 Dunkerton | View |
|---|---|---|---|
| KDMX Des Moines, IA | 99 mi southwest | 9,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KARX La Crosse, WI | 99 mi north-northeast | 9,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDVN Quad Cities, IA | 105 mi southeast | 10,300 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.
