Which radars cover Harrisville?
The closest NEXRAD Doppler radar is KMKX (Milwaukee/Sullivan, WI), about 77 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 Harrisville | View |
|---|---|---|---|
| KMKX Milwaukee/Sullivan, WI | 77 mi southeast | 6,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGRB Green Bay, WI | 77 mi northeast | 6,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KARX La Crosse, WI | 89 mi west | 8,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
