Which radars cover Arion?
The closest NEXRAD Doppler radar is KOAX (Omaha, NE), about 64 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 Arion | View |
|---|---|---|---|
| KOAX Omaha, NE | 64 mi southwest | 5,000 ft | Good — most storms and steady rain or snow show clearly |
| KDMX Des Moines, IA | 91 mi east | 8,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KFSD Sioux Falls, SD | 130 mi north-northwest | 14,500 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.
