Which radars cover Pomeroy?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 75 miles 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 Pomeroy | View |
|---|---|---|---|
| KDMX Des Moines, IA | 75 mi southeast | 6,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KOAX Omaha, NE | 122 mi southwest | 13,000 ft | Limited — the beam overshoots the lowest part of storms |
| KFSD Sioux Falls, SD | 126 mi northwest | 13,700 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.
