Which radars cover Cascade?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 52 miles south-southeast. 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 Cascade | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 52 mi south-southeast | 3,800 ft | Good — most storms and steady rain or snow show clearly |
| KARX La Crosse, WI | 106 mi north | 10,400 ft | Limited — the beam overshoots the lowest part of storms |
| KMKX Milwaukee/Sullivan, WI | 133 mi east-northeast | 15,000 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.
