Which radars cover Percy?
The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 75 miles northwest. 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 Percy | View |
|---|---|---|---|
| KLSX St. Louis, MO | 75 mi northwest | 6,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KPAH Paducah, KY | 80 mi southeast | 6,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KVWX Evansville, IN | 104 mi east | 10,300 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.
