Which radars cover Brillion?
The closest NEXRAD Doppler radar is KGRB (Green Bay, WI), about 23 miles north. 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 Brillion | View |
|---|---|---|---|
| KGRB Green Bay, WI | 23 mi north | 1,300 ft | Excellent — the lowest scan sees close to the ground |
| KMKX Milwaukee/Sullivan, WI | 87 mi south-southwest | 7,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGRR Grand Rapids, MI | 154 mi southeast | 19,000 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.
