Which radars cover Dunnell?

The closest NEXRAD Doppler radar is KFSD (Sioux Falls, SD), about 98 miles west. 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 Dunnell	View
KFSD Sioux Falls, SD	98 mi west	9,300 ft	Fair — the beam can pass over shallow snow and low-level rotation
KMPX Minneapolis, MN	107 mi north-northeast	10,700 ft	Limited — the beam overshoots the lowest part of storms
KDMX Des Moines, IA	137 mi south-southeast	15,700 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.
