Which radars cover Coon Valley?
The closest NEXRAD Doppler radar is KARX (La Crosse, WI), about 12 miles northwest. 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 Coon Valley | View |
|---|---|---|---|
| KARX La Crosse, WI | 12 mi northwest | 600 ft | Excellent — the lowest scan sees close to the ground |
| KMKX Milwaukee/Sullivan, WI | 134 mi east-southeast | 15,100 ft | Limited — the beam overshoots the lowest part of storms |
| KDVN Quad Cities, IA | 146 mi south | 17,400 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.
