The closest NEXRAD Doppler radar is KMQT (Marquette, MI), about 67 miles south-southeast. 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 Copper Harbor | View |
|---|---|---|---|
| KMQT Marquette, MI | 67 mi south-southeast | 5,300 ft | Good — most storms and steady rain or snow show clearly |
