Which radars cover Chesterfield?
The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 51 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 Chesterfield | View |
|---|---|---|---|
| KLSX St. Louis, MO | 51 mi southwest | 3,600 ft | Good — most storms and steady rain or snow show clearly |
| KILX Lincoln, IL | 73 mi north-northeast | 6,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KVWX Evansville, IN | 144 mi east-southeast | 17,000 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.
