Which radars cover Unionville?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 83 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 Unionville | View |
|---|---|---|---|
| KDMX Des Moines, IA | 83 mi northwest | 7,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDVN Quad Cities, IA | 123 mi east-northeast | 13,200 ft | Limited — the beam overshoots the lowest part of storms |
| KEAX Kansas City, MO | 162 mi south-southwest | 20,500 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.
