Which radars cover Greybull?
The closest NEXRAD Doppler radar is KBLX (Billings, MT), about 98 miles north-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 Greybull | View |
|---|---|---|---|
| KBLX Billings, MT | 98 mi north-northwest | 9,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KRIW Riverton, WY | 100 mi south-southwest | 9,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KSFX Pocatello, ID | 250 mi west-southwest | 42,700 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.
