Which radars cover Marion?
The closest NEXRAD Doppler radar is KARX (La Crosse, WI), about 58 miles east. 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 Marion | View |
|---|---|---|---|
| KARX La Crosse, WI | 58 mi east | 4,400 ft | Good — most storms and steady rain or snow show clearly |
| KMPX Minneapolis, MN | 87 mi northwest | 7,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDMX Des Moines, IA | 168 mi south-southwest | 21,800 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.
