Which radars cover Truman?
The closest NEXRAD Doppler radar is KMPX (Minneapolis, MN), about 83 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 Truman | View |
|---|---|---|---|
| KMPX Minneapolis, MN | 83 mi north-northeast | 7,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KFSD Sioux Falls, SD | 116 mi west | 12,000 ft | Limited — the beam overshoots the lowest part of storms |
| KDMX Des Moines, IA | 149 mi south-southeast | 18,000 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.
