Which radars cover Troy?
The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 24 miles 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 Troy | View |
|---|---|---|---|
| KLSX St. Louis, MO | 24 mi southeast | 1,400 ft | Excellent — the lowest scan sees close to the ground |
| KILX Lincoln, IL | 119 mi northeast | 12,600 ft | Limited — the beam overshoots the lowest part of storms |
| KEAX Kansas City, MO | 178 mi west | 24,000 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.
