Which radars cover Marcus?
The closest NEXRAD Doppler radar is KFSD (Sioux Falls, SD), about 70 miles northwest. 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 Marcus | View |
|---|---|---|---|
| KFSD Sioux Falls, SD | 70 mi northwest | 5,700 ft | Good — most storms and steady rain or snow show clearly |
| KOAX Omaha, NE | 108 mi south-southwest | 10,800 ft | Limited — the beam overshoots the lowest part of storms |
| KDMX Des Moines, IA | 131 mi southeast | 14,500 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.
