Which radars cover Sioux Center?
The closest NEXRAD Doppler radar is KFSD (Sioux Falls, SD), about 45 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 Sioux Center | View |
|---|---|---|---|
| KFSD Sioux Falls, SD | 45 mi northwest | 3,100 ft | Good — most storms and steady rain or snow show clearly |
| KOAX Omaha, NE | 122 mi south | 13,000 ft | Limited — the beam overshoots the lowest part of storms |
| KDMX Des Moines, IA | 156 mi southeast | 19,300 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.
