Which radars cover Dayton?
The closest NEXRAD Doppler radar is KMSX (Missoula, MT), about 59 miles south-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 Dayton | View |
|---|---|---|---|
| KMSX Missoula, MT | 59 mi south-southeast | 4,400 ft | Good — most storms and steady rain or snow show clearly |
| KTFX Great Falls, MT | 137 mi east | 15,800 ft | Limited — the beam overshoots the lowest part of storms |
| KOTX Spokane, WA | 156 mi west | 19,400 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.
