Which radars cover Osseo?
The closest NEXRAD Doppler radar is KARX (La Crosse, WI), about 52 miles south. 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 Osseo | View |
|---|---|---|---|
| KARX La Crosse, WI | 52 mi south | 3,800 ft | Good — most storms and steady rain or snow show clearly |
| KMPX Minneapolis, MN | 117 mi west | 12,200 ft | Limited — the beam overshoots the lowest part of storms |
| KGRB Green Bay, WI | 153 mi east | 18,700 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.
