Which radars cover Troy?
The closest NEXRAD Doppler radar is KPAH (Paducah, KY), about 55 miles north-northeast. 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 Troy | View |
|---|---|---|---|
| KPAH Paducah, KY | 55 mi north-northeast | 4,000 ft | Good — most storms and steady rain or snow show clearly |
| KNQA Memphis, TN | 80 mi south-southwest | 6,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KHPX Fort Campbell, KY | 108 mi east-northeast | 10,700 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.
