Which radars cover Mount Vernon?
The closest NEXRAD Doppler radar is KFSD (Sioux Falls, SD), about 77 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 Mount Vernon | View |
|---|---|---|---|
| KFSD Sioux Falls, SD | 77 mi east | 6,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KABR Aberdeen, SD | 121 mi north | 12,800 ft | Limited — the beam overshoots the lowest part of storms |
| KLNX North Platte, NE | 169 mi southwest | 22,000 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.
