Which radars cover Leland Grove?
The closest NEXRAD Doppler radar is KILX (Lincoln, IL), about 32 miles northeast. 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 Leland Grove | View |
|---|---|---|---|
| KILX Lincoln, IL | 32 mi northeast | 2,000 ft | Excellent — the lowest scan sees close to the ground |
| KLSX St. Louis, MO | 92 mi southwest | 8,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDVN Quad Cities, IA | 135 mi north-northwest | 15,400 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.
