Which radars cover Marengo?
The closest NEXRAD Doppler radar is KDLH (Duluth, MN), about 72 miles west-northwest. 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 Marengo | View |
|---|---|---|---|
| KDLH Duluth, MN | 72 mi west-northwest | 6,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMQT Marquette, MI | 155 mi east | 19,200 ft | Limited — the beam overshoots the lowest part of storms |
| KMPX Minneapolis, MN | 172 mi southwest | 22,700 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.
