Which radars cover Trenton?
The closest NEXRAD Doppler radar is KEAX (Kansas City, MO), about 95 miles south-southwest. 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 Trenton | View |
|---|---|---|---|
| KEAX Kansas City, MO | 95 mi south-southwest | 8,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDMX Des Moines, IA | 114 mi north | 11,800 ft | Limited — the beam overshoots the lowest part of storms |
| KTWX Topeka, KS | 159 mi west-southwest | 19,900 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.
