Which radars cover Jamesville Colony?
The closest NEXRAD Doppler radar is KFSD (Sioux Falls, SD), about 51 miles northeast. 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 Jamesville Colony | View |
|---|---|---|---|
| KFSD Sioux Falls, SD | 51 mi northeast | 3,600 ft | Good — most storms and steady rain or snow show clearly |
