Which radars cover Coral?
The closest NEXRAD Doppler radar is KLOT (Chicago, IL), about 49 miles south-southeast. 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 Coral | View |
|---|---|---|---|
| KLOT Chicago, IL | 49 mi south-southeast | 3,500 ft | Good — most storms and steady rain or snow show clearly |
| KMKX Milwaukee/Sullivan, WI | 52 mi north | 3,700 ft | Good — most storms and steady rain or snow show clearly |
| KDVN Quad Cities, IA | 112 mi west-southwest | 11,400 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.
