Which radars cover Hermann?
The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 41 miles east. 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 Hermann | View |
|---|---|---|---|
| KLSX St. Louis, MO | 41 mi east | 2,700 ft | Excellent — the lowest scan sees close to the ground |
| KSGF Springfield, MO | 147 mi 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.
