Which radars cover Glencoe?
The closest NEXRAD Doppler radar is KLOT (Chicago, IL), about 40 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 Glencoe | View |
|---|---|---|---|
| KLOT Chicago, IL | 40 mi south-southwest | 2,700 ft | Excellent — the lowest scan sees close to the ground |
| KMKX Milwaukee/Sullivan, WI | 70 mi northwest | 5,700 ft | Good — most storms and steady rain or snow show clearly |
| KIWX Fort Wayne, IN | 119 mi east-southeast | 12,600 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.
