Which radars cover Hopkinton?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 61 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 Hopkinton | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 61 mi southeast | 4,700 ft | Good — most storms and steady rain or snow show clearly |
| KARX La Crosse, WI | 102 mi north | 9,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDMX Des Moines, IA | 134 mi west-southwest | 15,100 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.
