Which radars cover Darien?
The closest NEXRAD Doppler radar is KMKX (Milwaukee/Sullivan, WI), about 27 miles north-northeast. 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 Darien | View |
|---|---|---|---|
| KMKX Milwaukee/Sullivan, WI | 27 mi north-northeast | 1,600 ft | Excellent — the lowest scan sees close to the ground |
| KLOT Chicago, IL | 76 mi south-southeast | 6,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDVN Quad Cities, IA | 118 mi southwest | 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.
