| Radar | Distance | Lowest beam over Belvidere | View |
|---|---|---|---|
| KMKX Milwaukee/Sullivan, WI | 51 mi north-northeast | 3,700 ft | Good — most storms and steady rain or snow show clearly |

| KDVN Quad Cities, IA | 98 mi west-southwest | 9,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
