Which radars cover Sandoval?
The closest NEXRAD Doppler radar is KVWX (Evansville, IN), about 79 miles east-southeast. 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 Sandoval | View |
|---|---|---|---|
| KVWX Evansville, IN | 79 mi east-southeast | 6,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLSX St. Louis, MO | 85 mi west | 7,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KILX Lincoln, IL | 107 mi north | 10,600 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.
