Which radars cover Chestnut?
The closest NEXRAD Doppler radar is KILX (Lincoln, IL), about 10 miles 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 Chestnut | View |
|---|---|---|---|
| KILX Lincoln, IL | 10 mi northwest | 500 ft | Excellent — the lowest scan sees close to the ground |
| KLOT Chicago, IL | 122 mi north-northeast | 13,000 ft | Limited — the beam overshoots the lowest part of storms |
| KLSX St. Louis, MO | 123 mi southwest | 13,200 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.
