Which radars cover Cainsville?

The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 89 miles north. 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 Cainsville	View
KDMX Des Moines, IA	89 mi north	8,100 ft	Fair — the beam can pass over shallow snow and low-level rotation
KEAX Kansas City, MO	116 mi south-southwest	12,000 ft	Limited — the beam overshoots the lowest part of storms
KOAX Omaha, NE	148 mi west-northwest	17,900 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.
