Which radars cover Allerton?
The closest NEXRAD Doppler radar is KILX (Lincoln, IL), about 76 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 Allerton | View |
|---|---|---|---|
| KILX Lincoln, IL | 76 mi west-northwest | 6,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |

| KVWX Evansville, IN | 115 mi south | 11,900 ft | Limited — the beam overshoots the lowest part of storms |
