Which radars cover St. Leo?
The closest NEXRAD Doppler radar is KFSD (Sioux Falls, SD), about 85 miles south-southwest. 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. Leo | View |
|---|---|---|---|
| KFSD Sioux Falls, SD | 85 mi south-southwest | 7,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMPX Minneapolis, MN | 122 mi east | 13,100 ft | Limited — the beam overshoots the lowest part of storms |
| KABR Aberdeen, SD | 126 mi west-northwest | 13,700 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.
