Which radars cover Mapleton?

The closest NEXRAD Doppler radar is KOAX (Omaha, NE), about 66 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 Mapleton	View
KOAX Omaha, NE	66 mi south-southwest	5,200 ft	Good — most storms and steady rain or snow show clearly
KFSD Sioux Falls, SD	109 mi north-northwest	11,000 ft	Limited — the beam overshoots the lowest part of storms
KDMX Des Moines, IA	110 mi east-southeast	11,200 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.
