Which radars cover Big Horn?
The closest NEXRAD Doppler radar is KBLX (Billings, MT), about 113 miles 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 Big Horn | View |
|---|---|---|---|
| KBLX Billings, MT | 113 mi northwest | 11,600 ft | Limited — the beam overshoots the lowest part of storms |
| KRIW Riverton, WY | 134 mi southwest | 15,100 ft | Limited — the beam overshoots the lowest part of storms |
| KUDX Rapid City, SD | 209 mi east | 31,500 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.
