Which radars cover Rockton?
The closest NEXRAD Doppler radar is KMKX (Milwaukee/Sullivan, WI), about 44 miles 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 Rockton | View |
|---|---|---|---|
| KMKX Milwaukee/Sullivan, WI | 44 mi northeast | 3,000 ft | Good — most storms and steady rain or snow show clearly |
| KLOT Chicago, IL | 77 mi southeast | 6,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDVN Quad Cities, IA | 97 mi southwest | 9,200 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.
