Which radars cover Augusta?
The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 14 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 Augusta | View |
|---|---|---|---|
| KLSX St. Louis, MO | 14 mi northeast | 700 ft | Excellent — the lowest scan sees close to the ground |
| KILX Lincoln, IL | 137 mi northeast | 15,700 ft | Limited — the beam overshoots the lowest part of storms |
| KPAH Paducah, KY | 155 mi southeast | 19,200 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.
