Which radars cover Mahnomen?
The closest NEXRAD Doppler radar is KDLH (Duluth, MN), about 16 miles east-northeast. 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 Mahnomen | View |
|---|---|---|---|
| KDLH Duluth, MN | 16 mi east-northeast | 900 ft | Excellent — the lowest scan sees close to the ground |
| KMPX Minneapolis, MN | 142 mi south-southwest | 16,600 ft | Limited — the beam overshoots the lowest part of storms |
| KARX La Crosse, WI | 214 mi south-southeast | 32,800 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.
