Which radars cover Doon?

The closest NEXRAD Doppler radar is KFSD (Sioux Falls, SD), about 33 miles 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 Doon	View
KFSD Sioux Falls, SD	33 mi northwest	2,000 ft	Excellent — the lowest scan sees close to the ground
KOAX Omaha, NE	136 mi south	15,400 ft	Limited — the beam overshoots the lowest part of storms
KDMX Des Moines, IA	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.
