Which radars cover Shellsburg?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 74 miles east-southeast. 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 Shellsburg | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 74 mi east-southeast | 6,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDMX Des Moines, IA | 98 mi west-southwest | 9,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KARX La Crosse, WI | 124 mi north-northeast | 13,500 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.
