Which radars cover Oskaloosa?

The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 64 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 Oskaloosa	View
KDMX Des Moines, IA	64 mi west-northwest	5,000 ft	Good — most storms and steady rain or snow show clearly
KDVN Quad Cities, IA	109 mi east-northeast	11,000 ft	Limited — the beam overshoots the lowest part of storms
KARX La Crosse, WI	190 mi north-northeast	26,800 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.
