Which radars cover Harrison?
The closest NEXRAD Doppler radar is KGRB (Green Bay, WI), about 23 miles north-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 Harrison | View |
|---|---|---|---|
| KGRB Green Bay, WI | 23 mi north-northeast | 1,300 ft | Excellent — the lowest scan sees close to the ground |
| KMKX Milwaukee/Sullivan, WI | 86 mi south | 7,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KARX La Crosse, WI | 146 mi west | 17,400 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.
