Which radars cover Jerseyville?
The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 35 miles south-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 Jerseyville | View |
|---|---|---|---|
| KLSX St. Louis, MO | 35 mi south-southwest | 2,200 ft | Excellent — the lowest scan sees close to the ground |
| KILX Lincoln, IL | 89 mi northeast | 8,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KVWX Evansville, IN | 152 mi east-southeast | 18,600 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.
