Which radars cover Williamsville?
The closest NEXRAD Doppler radar is KPAH (Paducah, KY), about 98 miles east. 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 Williamsville | View |
|---|---|---|---|
| KPAH Paducah, KY | 98 mi east | 9,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KNQA Memphis, TN | 119 mi south-southeast | 12,500 ft | Limited — the beam overshoots the lowest part of storms |
| KLSX St. Louis, MO | 119 mi north | 12,600 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.
