Which radars cover Calvin?

The closest NEXRAD Doppler radar is KMBX (Minot AFB, ND), about 94 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 Calvin	View
KMBX Minot AFB, ND	94 mi west-southwest	8,700 ft	Fair — the beam can pass over shallow snow and low-level rotation
KMVX Grand Forks, ND	118 mi southeast	12,400 ft	Limited — the beam overshoots the lowest part of storms
KBIS Bismarck, ND	167 mi south-southwest	21,600 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.
