Which radars cover Boy River?
The closest NEXRAD Doppler radar is KDLH (Duluth, MN), about 93 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 Boy River | View |
|---|---|---|---|
| KDLH Duluth, MN | 93 mi east-southeast | 8,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMVX Grand Forks, ND | 152 mi west | 18,500 ft | Limited — the beam overshoots the lowest part of storms |
| KMPX Minneapolis, MN | 162 mi south | 20,700 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.
