Which radars cover Grassland Colony?
The closest NEXRAD Doppler radar is KABR (Aberdeen, SD), about 24 miles southeast. 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 Grassland Colony | View |
|---|---|---|---|
| KABR Aberdeen, SD | 24 mi southeast | 1,400 ft | Excellent — the lowest scan sees close to the ground |
