Which radars cover Caledonia?
The closest NEXRAD Doppler radar is KMKX (Milwaukee/Sullivan, WI), about 45 miles north-northeast. 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 Caledonia | View |
|---|---|---|---|
| KMKX Milwaukee/Sullivan, WI | 45 mi north-northeast | 3,100 ft | Good — most storms and steady rain or snow show clearly |
| KLOT Chicago, IL | 67 mi southeast | 5,400 ft | Good — most storms and steady rain or snow show clearly |
| KDVN Quad Cities, IA | 101 mi west-southwest | 9,800 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.
