Which radars cover Percival?
The closest NEXRAD Doppler radar is KOAX (Omaha, NE), about 49 miles 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 Percival | View |
|---|---|---|---|
| KOAX Omaha, NE | 49 mi northwest | 3,400 ft | Good — most storms and steady rain or snow show clearly |
| KTWX Topeka, KS | 123 mi south | 13,300 ft | Limited — the beam overshoots the lowest part of storms |
| KDMX Des Moines, IA | 128 mi east-northeast | 14,100 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.
