Which radars cover Marble Rock?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 96 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 Marble Rock | View |
|---|---|---|---|
| KDMX Des Moines, IA | 96 mi south-southwest | 9,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KARX La Crosse, WI | 103 mi northeast | 10,000 ft | Limited — the beam overshoots the lowest part of storms |
| KMPX Minneapolis, MN | 135 mi north-northwest | 15,300 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.
