Which radars cover Corvallis?
The closest NEXRAD Doppler radar is KMSX (Missoula, MT), about 51 miles north. 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 Corvallis | View |
|---|---|---|---|
| KMSX Missoula, MT | 51 mi north | 3,600 ft | Good — most storms and steady rain or snow show clearly |
| KTFX Great Falls, MT | 151 mi east-northeast | 18,400 ft | Limited — the beam overshoots the lowest part of storms |
| KOTX Spokane, WA | 191 mi west-northwest | 27,000 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.
