Which radars cover Herman?

The closest NEXRAD Doppler radar is KABR (Aberdeen, SD), about 112 miles west-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 Herman	View
KABR Aberdeen, SD	112 mi west-southwest	11,500 ft	Limited — the beam overshoots the lowest part of storms
KMVX Grand Forks, ND	131 mi north-northwest	14,700 ft	Limited — the beam overshoots the lowest part of storms
KMPX Minneapolis, MN	142 mi east-southeast	16,600 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.
