Which radars cover Sundance?
The closest NEXRAD Doppler radar is KUDX (Rapid City, SD), about 78 miles east-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 Sundance | View |
|---|---|---|---|
| KUDX Rapid City, SD | 78 mi east-southeast | 6,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KRIW Riverton, WY | 225 mi west-southwest | 35,700 ft | Limited — the beam overshoots the lowest part of storms |
| KCYS Cheyenne, WY | 226 mi south | 35,900 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.
