Which radars cover Duncombe?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 53 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 Duncombe | View |
|---|---|---|---|
| KDMX Des Moines, IA | 53 mi south-southeast | 3,800 ft | Good — most storms and steady rain or snow show clearly |
