Which radars cover La Salle?
The closest NEXRAD Doppler radar is KMPX (Minneapolis, MN), about 73 miles 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 La Salle | View |
|---|---|---|---|
| KMPX Minneapolis, MN | 73 mi northeast | 6,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KFSD Sioux Falls, SD | 113 mi west-southwest | 11,500 ft | Limited — the beam overshoots the lowest part of storms |
| KDMX Des Moines, IA | 167 mi south-southeast | 21,700 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.
