Which radars cover Mendon?
The closest NEXRAD Doppler radar is KEAX (Kansas City, MO), about 81 miles southwest. 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 Mendon | View |
|---|---|---|---|
| KEAX Kansas City, MO | 81 mi southwest | 7,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLSX St. Louis, MO | 145 mi east-southeast | 17,200 ft | Limited — the beam overshoots the lowest part of storms |
| KDMX Des Moines, IA | 151 mi north-northwest | 18,400 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.
