Which radars cover Marietta?
The closest NEXRAD Doppler radar is KFSD (Sioux Falls, SD), about 99 miles south. 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 Marietta | View |
|---|---|---|---|
| KFSD Sioux Falls, SD | 99 mi south | 9,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KABR Aberdeen, SD | 102 mi west-northwest | 9,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMPX Minneapolis, MN | 140 mi east | 16,300 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.
