Which radars cover Nashua?
The closest NEXRAD Doppler radar is KARX (La Crosse, WI), about 91 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 Nashua | View |
|---|---|---|---|
| KARX La Crosse, WI | 91 mi northeast | 8,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDMX Des Moines, IA | 104 mi southwest | 10,100 ft | Limited — the beam overshoots the lowest part of storms |
| KDVN Quad Cities, IA | 136 mi southeast | 15,600 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.
