Which radars cover De Kalb?
The closest NEXRAD Doppler radar is KEAX (Kansas City, MO), about 64 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 De Kalb | View |
|---|---|---|---|
| KEAX Kansas City, MO | 64 mi south-southeast | 5,000 ft | Good — most storms and steady rain or snow show clearly |
| KTWX Topeka, KS | 81 mi west-southwest | 7,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KOAX Omaha, NE | 142 mi north-northwest | 16,600 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.
