Which radars cover Green Valley?
The closest NEXRAD Doppler radar is KILX (Lincoln, IL), about 24 miles 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 Green Valley | View |
|---|---|---|---|
| KILX Lincoln, IL | 24 mi southeast | 1,400 ft | Excellent — the lowest scan sees close to the ground |
| KDVN Quad Cities, IA | 97 mi north-northwest | 9,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLOT Chicago, IL | 116 mi northeast | 12,100 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.
