Which radars cover Colby?
The closest NEXRAD Doppler radar is KARX (La Crosse, WI), about 87 miles south-southwest. 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 Colby | View |
|---|---|---|---|
| KARX La Crosse, WI | 87 mi south-southwest | 7,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGRB Green Bay, WI | 112 mi east-southeast | 11,400 ft | Limited — the beam overshoots the lowest part of storms |
| KMPX Minneapolis, MN | 159 mi west | 20,000 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.
