Which radars cover Sister Bay?
The closest NEXRAD Doppler radar is KGRB (Green Bay, WI), about 68 miles 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 Sister Bay | View |
|---|---|---|---|
| KGRB Green Bay, WI | 68 mi southwest | 5,400 ft | Good — most storms and steady rain or snow show clearly |
| KMQT Marquette, MI | 95 mi north-northwest | 8,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KAPX Gaylord, MI | 119 mi east | 12,600 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.
