Which radars cover Dayville?
The closest NEXRAD Doppler radar is KPDT (Pendleton, OR), about 91 miles north-northeast. 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 Dayville | View |
|---|---|---|---|
| KPDT Pendleton, OR | 91 mi north-northeast | 8,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCBX Boise, ID | 177 mi east-southeast | 23,900 ft | Limited — the beam overshoots the lowest part of storms |
| KRTX Portland, OR | 188 mi west-northwest | 26,400 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.
