Which radars cover Andover?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 31 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 Andover | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 31 mi south-southwest | 1,900 ft | Excellent — the lowest scan sees close to the ground |
| KMKX Milwaukee/Sullivan, WI | 110 mi northeast | 11,200 ft | Limited — the beam overshoots the lowest part of storms |
| KLOT Chicago, IL | 115 mi east-southeast | 11,900 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.
