Which radars cover Coulter?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 72 miles south-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 Coulter | View |
|---|---|---|---|
| KDMX Des Moines, IA | 72 mi south-southwest | 5,900 ft | Good — most storms and steady rain or snow show clearly |
| KARX La Crosse, WI | 133 mi northeast | 15,000 ft | Limited — the beam overshoots the lowest part of storms |
| KMPX Minneapolis, MN | 147 mi north | 17,500 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.
