Which radars cover Twin Brooks?
The closest NEXRAD Doppler radar is KABR (Aberdeen, SD), about 81 miles west-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 Twin Brooks | View |
|---|---|---|---|
| KABR Aberdeen, SD | 81 mi west-northwest | 7,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KFSD Sioux Falls, SD | 112 mi south | 11,400 ft | Limited — the beam overshoots the lowest part of storms |
| KMPX Minneapolis, MN | 159 mi east | 20,000 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.
