Which radars cover Eureka?
The closest NEXRAD Doppler radar is KGRB (Green Bay, WI), about 49 miles northeast. 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 Eureka | View |
|---|---|---|---|
| KGRB Green Bay, WI | 49 mi northeast | 3,500 ft | Good — most storms and steady rain or snow show clearly |
| KMKX Milwaukee/Sullivan, WI | 74 mi south-southeast | 6,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KARX La Crosse, WI | 118 mi west | 12,300 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.
