Which radars cover Walnut Grove?
The closest NEXRAD Doppler radar is KFSD (Sioux Falls, SD), about 77 miles southwest. 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 Walnut Grove | View |
|---|---|---|---|
| KFSD Sioux Falls, SD | 77 mi southwest | 6,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMPX Minneapolis, MN | 103 mi east-northeast | 10,100 ft | Limited — the beam overshoots the lowest part of storms |
| KABR Aberdeen, SD | 167 mi west-northwest | 21,700 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.
