Which radars cover Norris?
The closest NEXRAD Doppler radar is KUDX (Rapid City, SD), about 93 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 Norris | View |
|---|---|---|---|
| KUDX Rapid City, SD | 93 mi west-northwest | 8,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLNX North Platte, NE | 109 mi south-southeast | 11,000 ft | Limited — the beam overshoots the lowest part of storms |
| KABR Aberdeen, SD | 194 mi northeast | 27,700 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.
