Which radars cover Arrowsmith?
The closest NEXRAD Doppler radar is KILX (Lincoln, IL), about 43 miles west-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 Arrowsmith | View |
|---|---|---|---|
| KILX Lincoln, IL | 43 mi west-southwest | 2,900 ft | Excellent — the lowest scan sees close to the ground |
| KLOT Chicago, IL | 85 mi north-northeast | 7,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDVN Quad Cities, IA | 130 mi northwest | 14,400 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.
