Which radars cover Colo?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 29 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 Colo | View |
|---|---|---|---|
| KDMX Des Moines, IA | 29 mi southwest | 1,700 ft | Excellent — the lowest scan sees close to the ground |
| KDVN Quad Cities, IA | 144 mi east | 16,900 ft | Limited — the beam overshoots the lowest part of storms |
| KOAX Omaha, NE | 165 mi west-southwest | 21,100 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.
