Which radars cover Sun Valley?
The closest NEXRAD Doppler radar is KSFX (Pocatello, ID), about 92 miles east-southeast. 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 Sun Valley | View |
|---|---|---|---|
| KSFX Pocatello, ID | 92 mi east-southeast | 8,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCBX Boise, ID | 96 mi west | 9,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMTX Salt Lake City, UT | 193 mi south-southeast | 27,500 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.
