Which radars cover Roslyn?

The closest NEXRAD Doppler radar is KABR (Aberdeen, SD), about 45 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 Roslyn	View
KABR Aberdeen, SD	45 mi west	3,100 ft	Good — most storms and steady rain or snow show clearly
KFSD Sioux Falls, SD	137 mi south-southeast	15,700 ft	Limited — the beam overshoots the lowest part of storms
KMVX Grand Forks, ND	141 mi north	16,400 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.
