Which radars cover Atlantic?
The closest NEXRAD Doppler radar is KOAX (Omaha, NE), about 70 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 Atlantic | View |
|---|---|---|---|
| KOAX Omaha, NE | 70 mi west | 5,700 ft | Good — most storms and steady rain or snow show clearly |
| KDMX Des Moines, IA | 71 mi east-northeast | 5,800 ft | Good — most storms and steady rain or snow show clearly |
| KFSD Sioux Falls, SD | 175 mi north-northwest | 23,300 ft | Limited — the beam overshoots the lowest part of storms |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
