Which radars cover Jefferson?
The closest NEXRAD Doppler radar is KRTX (Portland, OR), about 69 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 Jefferson | View |
|---|---|---|---|
| KRTX Portland, OR | 69 mi north | 5,600 ft | Good — most storms and steady rain or snow show clearly |
| KLGX Langley Hill, WA | 174 mi north-northwest | 23,200 ft | Limited — the beam overshoots the lowest part of storms |
| KMAX Medford, OR | 183 mi south | 25,100 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.
