Which radars cover Herscher?
The closest NEXRAD Doppler radar is KLOT (Chicago, IL), about 38 miles north. 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 Herscher | View |
|---|---|---|---|
| KLOT Chicago, IL | 38 mi north | 2,500 ft | Excellent — the lowest scan sees close to the ground |
| KILX Lincoln, IL | 90 mi southwest | 8,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KIWX Fort Wayne, IN | 127 mi east | 13,900 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.
