Which radars cover Hartley?
The closest NEXRAD Doppler radar is KFSD (Sioux Falls, SD), about 69 miles west-northwest. 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 Hartley | View |
|---|---|---|---|
| KFSD Sioux Falls, SD | 69 mi west-northwest | 5,600 ft | Good — most storms and steady rain or snow show clearly |
| KDMX Des Moines, IA | 134 mi southeast | 15,200 ft | Limited — the beam overshoots the lowest part of storms |
| KOAX Omaha, NE | 136 mi south-southwest | 15,600 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.
