Which radars cover Green Bay?
The closest NEXRAD Doppler radar is KGRB (Green Bay, WI), about 6 miles west-southwest. 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 Green Bay | View |
|---|---|---|---|
| KGRB Green Bay, WI | 6 mi west-southwest | 300 ft | Excellent — the lowest scan sees close to the ground |
| KMKX Milwaukee/Sullivan, WI | 111 mi south-southwest | 11,300 ft | Limited — the beam overshoots the lowest part of storms |
| KMQT Marquette, MI | 140 mi north | 16,300 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.
