Which radars cover Troy?
The closest NEXRAD Doppler radar is KEAX (Kansas City, MO), about 81 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 Troy | View |
|---|---|---|---|
| KEAX Kansas City, MO | 81 mi south-southeast | 7,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KTWX Topeka, KS | 82 mi southwest | 7,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KOAX Omaha, NE | 125 mi north-northwest | 13,600 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.
