Which radars cover Clarkson?
The closest NEXRAD Doppler radar is KLVX (Louisville, KY), about 37 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 Clarkson | View |
|---|---|---|---|
| KLVX Louisville, KY | 37 mi north-northeast | 2,400 ft | Excellent — the lowest scan sees close to the ground |
| KHPX Fort Campbell, KY | 78 mi southwest | 6,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KOHX Nashville, TN | 88 mi south-southwest | 7,900 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.
