Which radars cover Blue Mound?
The closest NEXRAD Doppler radar is KILX (Lincoln, IL), about 33 miles north-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 Blue Mound | View |
|---|---|---|---|
| KILX Lincoln, IL | 33 mi north-northwest | 2,100 ft | Excellent — the lowest scan sees close to the ground |
