Which radars cover Geneseo?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 25 miles west-northwest. 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 Geneseo | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 25 mi west-northwest | 1,400 ft | Excellent — the lowest scan sees close to the ground |
| KILX Lincoln, IL | 100 mi south-southeast | 9,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLOT Chicago, IL | 108 mi east | 10,700 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.
