Which radars cover Nelsonville?
The closest NEXRAD Doppler radar is KGRB (Green Bay, WI), about 59 miles east. 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 Nelsonville | View |
|---|---|---|---|
| KGRB Green Bay, WI | 59 mi east | 4,400 ft | Good — most storms and steady rain or snow show clearly |
