Which radars cover Calumet?
The closest NEXRAD Doppler radar is KFSD (Sioux Falls, SD), about 74 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 Calumet | View |
|---|---|---|---|
| KFSD Sioux Falls, SD | 74 mi northwest | 6,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KOAX Omaha, NE | 120 mi south-southwest | 12,700 ft | Limited — the beam overshoots the lowest part of storms |
| KDMX Des Moines, IA | 126 mi southeast | 13,700 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.
