Which radars cover Le Roy?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 59 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 Le Roy | View |
|---|---|---|---|
| KDMX Des Moines, IA | 59 mi north | 4,500 ft | Good — most storms and steady rain or snow show clearly |
| KEAX Kansas City, MO | 147 mi south-southwest | 17,600 ft | Limited — the beam overshoots the lowest part of storms |
| KOAX Omaha, NE | 148 mi west-northwest | 17,700 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.
