Which radars cover Portland?
The closest NEXRAD Doppler radar is KOHX (Nashville, TN), about 24 miles south. 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 Portland | View |
|---|---|---|---|
| KOHX Nashville, TN | 24 mi south | 1,400 ft | Excellent — the lowest scan sees close to the ground |
| KHPX Fort Campbell, KY | 43 mi west-northwest | 2,900 ft | Excellent — the lowest scan sees close to the ground |
| KLVX Louisville, KY | 100 mi north-northeast | 9,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
