Which radars cover Junction City?
The closest NEXRAD Doppler radar is KGRB (Green Bay, WI), about 82 miles east. 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 Junction City | View |
|---|---|---|---|
| KGRB Green Bay, WI | 82 mi east | 7,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KARX La Crosse, WI | 88 mi southwest | 8,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMKX Milwaukee/Sullivan, WI | 128 mi south-southeast | 14,100 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.
