Which radars cover Grasston?
The closest NEXRAD Doppler radar is KMPX (Minneapolis, MN), about 69 miles south-southwest. 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 Grasston | View |
|---|---|---|---|
| KMPX Minneapolis, MN | 69 mi south-southwest | 5,500 ft | Good — most storms and steady rain or snow show clearly |
| KDLH Duluth, MN | 85 mi north-northeast | 7,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KARX La Crosse, WI | 167 mi southeast | 21,600 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.
