Which radars cover Tomah?
The closest NEXRAD Doppler radar is KARX (La Crosse, WI), about 36 miles west-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 Tomah | View |
|---|---|---|---|
| KARX La Crosse, WI | 36 mi west-southwest | 2,300 ft | Excellent — the lowest scan sees close to the ground |
| KMKX Milwaukee/Sullivan, WI | 121 mi southeast | 12,800 ft | Limited — the beam overshoots the lowest part of storms |
| KGRB Green Bay, WI | 123 mi east-northeast | 13,300 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.
