Which radars cover Harris?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 100 miles north. 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 Harris | View |
|---|---|---|---|
| KDMX Des Moines, IA | 100 mi north | 9,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KEAX Kansas City, MO | 114 mi south-southwest | 11,800 ft | Limited — the beam overshoots the lowest part of storms |
| KDVN Quad Cities, IA | 170 mi east-northeast | 22,400 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.
