Which radars cover Unionville?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 94 miles north-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 | 94 mi north-northwest | 8,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KEAX Kansas City, MO | 133 mi south-southwest | 15,000 ft | Limited — the beam overshoots the lowest part of storms |
| KDVN Quad Cities, IA | 149 mi east-northeast | 17,900 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.
