Which radars cover Sedan?
The closest NEXRAD Doppler radar is KINX (Tulsa, OK), about 74 miles south-southeast. 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 Sedan | View |
|---|---|---|---|
| KINX Tulsa, OK | 74 mi south-southeast | 6,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KICT Wichita, KS | 78 mi west-northwest | 6,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KVNX Vance AFB, OK | 111 mi west-southwest | 11,200 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.
