Which radars cover Elroy?
The closest NEXRAD Doppler radar is KARX (La Crosse, WI), about 46 miles west. 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 Elroy | View |
|---|---|---|---|
| KARX La Crosse, WI | 46 mi west | 3,200 ft | Good — most storms and steady rain or snow show clearly |
| KMKX Milwaukee/Sullivan, WI | 102 mi east-southeast | 9,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGRB Green Bay, WI | 119 mi east-northeast | 12,600 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.
