Which radars cover Manderson?
The closest NEXRAD Doppler radar is KRIW (Riverton, WY), about 87 miles south-southwest. 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 Manderson | View |
|---|---|---|---|
| KRIW Riverton, WY | 87 mi south-southwest | 7,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KBLX Billings, MT | 114 mi north-northwest | 11,700 ft | Limited — the beam overshoots the lowest part of storms |
| KSFX Pocatello, ID | 249 mi west-southwest | 42,600 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.
