Which radars cover Colesburg?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 78 miles south-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 Colesburg | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 78 mi south-southeast | 6,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KARX La Crosse, WI | 82 mi north | 7,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMKX Milwaukee/Sullivan, WI | 136 mi east | 15,600 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.
