Which radars cover Corwith?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 88 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 Corwith | View |
|---|---|---|---|
| KDMX Des Moines, IA | 88 mi south | 7,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMPX Minneapolis, MN | 130 mi north | 14,400 ft | Limited — the beam overshoots the lowest part of storms |
| KFSD Sioux Falls, SD | 145 mi west-northwest | 17,300 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.
