Which radars cover Monmouth?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 48 miles north. 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 Monmouth | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 48 mi north | 3,400 ft | Good — most storms and steady rain or snow show clearly |
| KILX Lincoln, IL | 87 mi southeast | 7,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLOT Chicago, IL | 141 mi east-northeast | 16,500 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.
