Which radars cover Newcastle?
The closest NEXRAD Doppler radar is KUDX (Rapid City, SD), about 71 miles east-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 Newcastle | View |
|---|---|---|---|
| KUDX Rapid City, SD | 71 mi east-northeast | 5,700 ft | Good — most storms and steady rain or snow show clearly |
| KCYS Cheyenne, WY | 189 mi south | 26,600 ft | Limited — the beam overshoots the lowest part of storms |
| KRIW Riverton, WY | 221 mi west-southwest | 34,700 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.
