Which radars cover Underwood?
The closest NEXRAD Doppler radar is KOAX (Omaha, NE), about 36 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 Underwood | View |
|---|---|---|---|
| KOAX Omaha, NE | 36 mi west | 2,300 ft | Excellent — the lowest scan sees close to the ground |
