Which radars cover New Lenox?
The closest NEXRAD Doppler radar is KLOT (Chicago, IL), about 9 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 New Lenox | View |
|---|---|---|---|
| KLOT Chicago, IL | 9 mi northwest | 400 ft | Excellent — the lowest scan sees close to the ground |
| KMKX Milwaukee/Sullivan, WI | 105 mi north-northwest | 10,400 ft | Limited — the beam overshoots the lowest part of storms |
| KIWX Fort Wayne, IN | 118 mi east | 12,400 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.
