Which radars cover Caledonia?
The closest NEXRAD Doppler radar is KARX (La Crosse, WI), about 20 miles 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 Caledonia | View |
|---|---|---|---|
| KARX La Crosse, WI | 20 mi northeast | 1,100 ft | Excellent — the lowest scan sees close to the ground |
| KMPX Minneapolis, MN | 132 mi northwest | 14,800 ft | Limited — the beam overshoots the lowest part of storms |
| KDVN Quad Cities, IA | 147 mi south-southeast | 17,600 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.
