Which radars cover Henderson?
The closest NEXRAD Doppler radar is KOAX (Omaha, NE), about 50 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 Henderson | View |
|---|---|---|---|
| KOAX Omaha, NE | 50 mi west-northwest | 3,600 ft | Good — most storms and steady rain or snow show clearly |
| KDMX Des Moines, IA | 97 mi east-northeast | 9,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KTWX Topeka, KS | 154 mi south-southwest | 19,000 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.
