Which radars cover Elm Grove?
The closest NEXRAD Doppler radar is KMKX (Milwaukee/Sullivan, WI), about 24 miles west-southwest. 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 Elm Grove | View |
|---|---|---|---|
| KMKX Milwaukee/Sullivan, WI | 24 mi west-southwest | 1,400 ft | Excellent — the lowest scan sees close to the ground |
| KLOT Chicago, IL | 100 mi south | 9,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGRB Green Bay, WI | 100 mi north | 9,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
