Which radars cover Agar?

The closest NEXRAD Doppler radar is KABR (Aberdeen, SD), about 91 miles east-northeast. 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 Agar	View
KABR Aberdeen, SD	91 mi east-northeast	8,400 ft	Fair — the beam can pass over shallow snow and low-level rotation
KBIS Bismarck, ND	138 mi north-northwest	15,800 ft	Limited — the beam overshoots the lowest part of storms
KUDX Rapid City, SD	145 mi west-southwest	17,100 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.
