Which radars cover Williams?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 53 miles south. 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 Williams | View |
|---|---|---|---|
| KDMX Des Moines, IA | 53 mi south | 3,900 ft | Good — most storms and steady rain or snow show clearly |
| KARX La Crosse, WI | 150 mi northeast | 18,200 ft | Limited — the beam overshoots the lowest part of storms |
| KMPX Minneapolis, MN | 163 mi north | 20,800 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.
