Which radars cover Iroquois?
The closest NEXRAD Doppler radar is KFSD (Sioux Falls, SD), about 78 miles 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 Iroquois | View |
|---|---|---|---|
| KFSD Sioux Falls, SD | 78 mi southeast | 6,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KABR Aberdeen, SD | 80 mi north-northwest | 6,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMPX Minneapolis, MN | 213 mi east | 32,600 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.
