Which radars cover Ironton?
The closest NEXRAD Doppler radar is KARX (La Crosse, WI), about 56 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 Ironton | View |
|---|---|---|---|
| KARX La Crosse, WI | 56 mi west-northwest | 4,100 ft | Good — most storms and steady rain or snow show clearly |
| KMKX Milwaukee/Sullivan, WI | 90 mi east-southeast | 8,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGRB Green Bay, WI | 121 mi northeast | 12,800 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.
