Which radars cover St. Clair?
The closest NEXRAD Doppler radar is KMPX (Minneapolis, MN), about 55 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 St. Clair | View |
|---|---|---|---|
| KMPX Minneapolis, MN | 55 mi north-northeast | 4,000 ft | Good — most storms and steady rain or snow show clearly |
| KARX La Crosse, WI | 134 mi east | 15,200 ft | Limited — the beam overshoots the lowest part of storms |
| KFSD Sioux Falls, SD | 147 mi west-southwest | 17,600 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.
