Which radars cover Harmon?

The closest NEXRAD Doppler radar is KBIS (Bismarck, ND), about 16 miles southeast. 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 Harmon	View
KBIS Bismarck, ND	16 mi southeast	800 ft	Excellent — the lowest scan sees close to the ground
KMBX Minot AFB, ND	100 mi north	9,500 ft	Fair — the beam can pass over shallow snow and low-level rotation
KABR Aberdeen, SD	160 mi southeast	20,100 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.
