Which radars cover Iatan?
The closest NEXRAD Doppler radar is KEAX (Kansas City, MO), about 60 miles 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 Iatan | View |
|---|---|---|---|
| KEAX Kansas City, MO | 60 mi southeast | 4,600 ft | Good — most storms and steady rain or snow show clearly |
| KTWX Topeka, KS | 75 mi west-southwest | 6,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KOAX Omaha, NE | 147 mi north-northwest | 17,500 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.
