Which radars cover Dike?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 76 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 Dike | View |
|---|---|---|---|
| KDMX Des Moines, IA | 76 mi southwest | 6,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KARX La Crosse, WI | 119 mi northeast | 12,500 ft | Limited — the beam overshoots the lowest part of storms |
| KDVN Quad Cities, IA | 120 mi east-southeast | 12,800 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.
