Which radars cover Blue Island?
The closest NEXRAD Doppler radar is KLOT (Chicago, IL), about 21 miles west. 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 Blue Island | View |
|---|---|---|---|
| KLOT Chicago, IL | 21 mi west | 1,200 ft | Excellent — the lowest scan sees close to the ground |
| KMKX Milwaukee/Sullivan, WI | 101 mi north-northwest | 9,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KIWX Fort Wayne, IN | 105 mi east | 10,300 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.
