Which radars cover Hanover?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 47 miles south-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 Hanover | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 47 mi south-southwest | 3,300 ft | Good — most storms and steady rain or snow show clearly |
| KMKX Milwaukee/Sullivan, WI | 101 mi east-northeast | 9,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KARX La Crosse, WI | 118 mi north-northwest | 12,400 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.
