Which radars cover Union Center?
The closest NEXRAD Doppler radar is KARX (La Crosse, WI), about 47 miles west-northwest. 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 Union Center | View |
|---|---|---|---|
| KARX La Crosse, WI | 47 mi west-northwest | 3,300 ft | Good — most storms and steady rain or snow show clearly |
| KMKX Milwaukee/Sullivan, WI | 99 mi east-southeast | 9,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGRB Green Bay, WI | 121 mi east-northeast | 12,900 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.
