Which radars cover Colwell?
The closest NEXRAD Doppler radar is KARX (La Crosse, WI), about 84 miles east-northeast. 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 Colwell | View |
|---|---|---|---|
| KARX La Crosse, WI | 84 mi east-northeast | 7,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDMX Des Moines, IA | 114 mi south-southwest | 11,800 ft | Limited — the beam overshoots the lowest part of storms |
| KMPX Minneapolis, MN | 127 mi north-northwest | 13,800 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.
