Which radars cover Round Lake Park?

| Radar | Distance | Lowest beam over Round Lake Park | View |
|---|---|---|---|
| KMKX Milwaukee/Sullivan, WI | 49 mi north-northwest | 3,500 ft | Good — most storms and steady rain or snow show clearly |

| KGRR Grand Rapids, MI | 135 mi east-northeast | 15,200 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.
