Which radars cover Trenton?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 67 miles 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 Trenton | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 67 mi northeast | 5,300 ft | Good — most storms and steady rain or snow show clearly |
| KDMX Des Moines, IA | 117 mi west-northwest | 12,300 ft | Limited — the beam overshoots the lowest part of storms |
| KILX Lincoln, IL | 136 mi east-southeast | 15,600 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.
