Which radars cover Grantsburg?
The closest NEXRAD Doppler radar is KDLH (Duluth, MN), about 76 miles north-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 Grantsburg | View |
|---|---|---|---|
| KDLH Duluth, MN | 76 mi north-northeast | 6,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMPX Minneapolis, MN | 78 mi southwest | 6,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KARX La Crosse, WI | 154 mi south-southeast | 18,900 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.
