Which radars cover Morrison?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 68 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 Morrison | View |
|---|---|---|---|
| KDMX Des Moines, IA | 68 mi southwest | 5,500 ft | Good — most storms and steady rain or snow show clearly |
| KDVN Quad Cities, IA | 119 mi east-southeast | 12,500 ft | Limited — the beam overshoots the lowest part of storms |
| KARX La Crosse, WI | 127 mi northeast | 13,900 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.
