Which radars cover Storm Lake?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 98 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 Storm Lake | View |
|---|---|---|---|
| KDMX Des Moines, IA | 98 mi southeast | 9,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KFSD Sioux Falls, SD | 101 mi northwest | 9,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KOAX Omaha, NE | 109 mi south-southwest | 11,000 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.
