Which radars cover St. Peters?
The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 7 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. Peters | View |
|---|---|---|---|
| KLSX St. Louis, MO | 7 mi southwest | 400 ft | Excellent — the lowest scan sees close to the ground |
| KILX Lincoln, IL | 116 mi northeast | 12,100 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.
