Which radars cover Oskaloosa?
The closest NEXRAD Doppler radar is KTWX (Topeka, KS), about 51 miles west-southwest. 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 Oskaloosa | View |
|---|---|---|---|
| KTWX Topeka, KS | 51 mi west-southwest | 3,700 ft | Good — most storms and steady rain or snow show clearly |

| KOAX Omaha, NE | 156 mi north-northwest | 19,300 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.
