Which radars cover Ashton?
The closest NEXRAD Doppler radar is KSFX (Pocatello, ID), about 91 miles 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 Ashton | View |
|---|---|---|---|
| KSFX Pocatello, ID | 91 mi southwest | 8,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KRIW Riverton, WY | 164 mi east-southeast | 21,100 ft | Limited — the beam overshoots the lowest part of storms |
| KBLX Billings, MT | 186 mi northeast | 25,800 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.
