Which radars cover Twin Grove?
The closest NEXRAD Doppler radar is KILX (Lincoln, IL), about 26 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 Twin Grove | View |
|---|---|---|---|
| KILX Lincoln, IL | 26 mi south-southwest | 1,500 ft | Excellent — the lowest scan sees close to the ground |
| KLOT Chicago, IL | 94 mi northeast | 8,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDVN Quad Cities, IA | 110 mi northwest | 11,100 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.
