Which radars cover Dellwood?
The closest NEXRAD Doppler radar is KARX (La Crosse, WI), about 63 miles west. 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 Dellwood | View |
|---|---|---|---|
| KARX La Crosse, WI | 63 mi west | 4,900 ft | Good — most storms and steady rain or snow show clearly |
