Which radars cover Dewey?
The closest NEXRAD Doppler radar is KMSX (Missoula, MT), about 103 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 Dewey | View |
|---|---|---|---|
| KMSX Missoula, MT | 103 mi north-northwest | 10,000 ft | Limited — the beam overshoots the lowest part of storms |

| KSFX Pocatello, ID | 185 mi south | 25,600 ft | Limited — the beam overshoots the lowest part of storms |
