Which radars cover Hebron?
The closest NEXRAD Doppler radar is KMKX (Milwaukee/Sullivan, WI), about 35 miles north. 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 Hebron | View |
|---|---|---|---|
| KMKX Milwaukee/Sullivan, WI | 35 mi north | 2,200 ft | Excellent — the lowest scan sees close to the ground |
| KLOT Chicago, IL | 62 mi south-southeast | 4,800 ft | Good — most storms and steady rain or snow show clearly |
| KDVN Quad Cities, IA | 125 mi west-southwest | 13,600 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.
