Which radars cover Holcomb?
The closest NEXRAD Doppler radar is KLOT (Chicago, IL), about 61 miles east-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 Holcomb | View |
|---|---|---|---|
| KLOT Chicago, IL | 61 mi east-southeast | 4,700 ft | Good — most storms and steady rain or snow show clearly |

| KDVN Quad Cities, IA | 83 mi west-southwest | 7,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
