Which radars cover Masonville?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 79 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 Masonville | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 79 mi southeast | 6,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KARX La Crosse, WI | 95 mi north-northeast | 8,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDMX Des Moines, IA | 121 mi west-southwest | 12,900 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.
