Which radars cover Grand Junction?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 34 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 Grand Junction | View |
|---|---|---|---|
| KDMX Des Moines, IA | 34 mi southeast | 2,100 ft | Excellent — the lowest scan sees close to the ground |
| KOAX Omaha, NE | 120 mi west-southwest | 12,800 ft | Limited — the beam overshoots the lowest part of storms |
| KFSD Sioux Falls, SD | 166 mi northwest | 21,400 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.
