Which radars cover Postville?
The closest NEXRAD Doppler radar is KARX (La Crosse, WI), about 54 miles north-northeast. 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 Postville | View |
|---|---|---|---|
| KARX La Crosse, WI | 54 mi north-northeast | 4,000 ft | Good — most storms and steady rain or snow show clearly |
| KDVN Quad Cities, IA | 114 mi south-southeast | 11,700 ft | Limited — the beam overshoots the lowest part of storms |
| KDMX Des Moines, IA | 144 mi southwest | 17,100 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.
