Which radars cover Dedham?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 58 miles east-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 Dedham | View |
|---|---|---|---|
| KDMX Des Moines, IA | 58 mi east-southeast | 4,400 ft | Good — most storms and steady rain or snow show clearly |
| KOAX Omaha, NE | 90 mi west-southwest | 8,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KFSD Sioux Falls, SD | 151 mi northwest | 18,400 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.
