Which radars cover De Graff?
The closest NEXRAD Doppler radar is KMPX (Minneapolis, MN), about 97 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 De Graff | View |
|---|---|---|---|
| KMPX Minneapolis, MN | 97 mi east-southeast | 9,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KFSD Sioux Falls, SD | 131 mi south-southwest | 14,700 ft | Limited — the beam overshoots the lowest part of storms |
| KABR Aberdeen, SD | 144 mi west | 16,900 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.
