Which radars cover Lake Summerset?
The closest NEXRAD Doppler radar is KMKX (Milwaukee/Sullivan, WI), about 55 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 Lake Summerset | View |
|---|---|---|---|
| KMKX Milwaukee/Sullivan, WI | 55 mi northeast | 4,100 ft | Good — most storms and steady rain or snow show clearly |
| KDVN Quad Cities, IA | 84 mi southwest | 7,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLOT Chicago, IL | 89 mi southeast | 8,100 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.
