Which radars cover Armour?
The closest NEXRAD Doppler radar is KFSD (Sioux Falls, SD), about 83 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 Armour | View |
|---|---|---|---|
| KFSD Sioux Falls, SD | 83 mi east-northeast | 7,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLNX North Platte, NE | 147 mi southwest | 17,700 ft | Limited — the beam overshoots the lowest part of storms |
| KABR Aberdeen, SD | 148 mi north | 17,700 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.
