Which radars cover Winnetka?
The closest NEXRAD Doppler radar is KLOT (Chicago, IL), about 39 miles south-southwest. 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 Winnetka | View |
|---|---|---|---|
| KLOT Chicago, IL | 39 mi south-southwest | 2,600 ft | Excellent — the lowest scan sees close to the ground |
| KMKX Milwaukee/Sullivan, WI | 72 mi northwest | 6,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KIWX Fort Wayne, IN | 117 mi east-southeast | 12,300 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.
