Which radars cover Terril?
The closest NEXRAD Doppler radar is KFSD (Sioux Falls, SD), about 90 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 Terril | View |
|---|---|---|---|
| KFSD Sioux Falls, SD | 90 mi west-northwest | 8,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDMX Des Moines, IA | 126 mi south-southeast | 13,700 ft | Limited — the beam overshoots the lowest part of storms |
| KMPX Minneapolis, MN | 127 mi north-northeast | 14,000 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.
