Which radars cover Deerfield?
The closest NEXRAD Doppler radar is KMKX (Milwaukee/Sullivan, WI), about 27 miles east-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 Deerfield | View |
|---|---|---|---|
| KMKX Milwaukee/Sullivan, WI | 27 mi east-southeast | 1,600 ft | Excellent — the lowest scan sees close to the ground |
| KGRB Green Bay, WI | 111 mi north-northeast | 11,300 ft | Limited — the beam overshoots the lowest part of storms |
| KLOT Chicago, IL | 112 mi south-southeast | 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.
