Which radars cover Trempealeau?
The closest NEXRAD Doppler radar is KARX (La Crosse, WI), about 17 miles southeast. 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 Trempealeau | View |
|---|---|---|---|
| KARX La Crosse, WI | 17 mi southeast | 900 ft | Excellent — the lowest scan sees close to the ground |
| KMPX Minneapolis, MN | 121 mi west-northwest | 12,800 ft | Limited — the beam overshoots the lowest part of storms |
| KMKX Milwaukee/Sullivan, WI | 161 mi east-southeast | 20,400 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.
