Which radars cover St. Charles?
The closest NEXRAD Doppler radar is KLNX (North Platte, NE), about 109 miles 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. Charles | View |
|---|---|---|---|
| KLNX North Platte, NE | 109 mi southwest | 10,900 ft | Limited — the beam overshoots the lowest part of storms |
