Which radars cover Shell Rock?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 90 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 Shell Rock | View |
|---|---|---|---|
| KDMX Des Moines, IA | 90 mi southwest | 8,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KARX La Crosse, WI | 104 mi northeast | 10,200 ft | Limited — the beam overshoots the lowest part of storms |
| KDVN Quad Cities, IA | 128 mi southeast | 14,000 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.
