Which radars cover Monticello?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 53 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 Monticello | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 53 mi southeast | 3,800 ft | Good — most storms and steady rain or snow show clearly |
| KARX La Crosse, WI | 110 mi north | 11,100 ft | Limited — the beam overshoots the lowest part of storms |
| KDMX Des Moines, IA | 135 mi west-southwest | 15,300 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.
