Which radars cover Harrison?
The closest NEXRAD Doppler radar is KFSD (Sioux Falls, SD), about 91 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 Harrison | View |
|---|---|---|---|
| KFSD Sioux Falls, SD | 91 mi east | 8,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KABR Aberdeen, SD | 140 mi north | 16,300 ft | Limited — the beam overshoots the lowest part of storms |
| KLNX North Platte, NE | 146 mi southwest | 17,300 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.
