Which radars cover Derby?
The closest NEXRAD Doppler radar is KICT (Wichita, KS), about 12 miles west-northwest. 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 Derby | View |
|---|---|---|---|
| KICT Wichita, KS | 12 mi west-northwest | 600 ft | Excellent — the lowest scan sees close to the ground |
| KVNX Vance AFB, OK | 74 mi southwest | 6,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KTWX Topeka, KS | 114 mi north-northeast | 11,700 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.
