Which radars cover Montour?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 55 miles west-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 Montour | View |
|---|---|---|---|
| KDMX Des Moines, IA | 55 mi west-southwest | 4,000 ft | Good — most storms and steady rain or snow show clearly |
| KDVN Quad Cities, IA | 113 mi east-southeast | 11,600 ft | Limited — the beam overshoots the lowest part of storms |
| KARX La Crosse, WI | 149 mi north-northeast | 17,900 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.
