Which radars cover St. Charles?
The closest NEXRAD Doppler radar is KMTX (Salt Lake City, UT), about 80 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 St. Charles | View |
|---|---|---|---|
| KMTX Salt Lake City, UT | 80 mi southwest | 6,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KSFX Pocatello, ID | 95 mi northwest | 8,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KRIW Riverton, WY | 162 mi east-northeast | 20,600 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.
