Which radars cover Palmyra?
The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 88 miles south-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 Palmyra | View |
|---|---|---|---|
| KLSX St. Louis, MO | 88 mi south-southeast | 8,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KILX Lincoln, IL | 118 mi east-northeast | 12,500 ft | Limited — the beam overshoots the lowest part of storms |
| KDVN Quad Cities, IA | 135 mi north-northeast | 15,300 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.
