Which radars cover St. Thomas?

The closest NEXRAD Doppler radar is KMVX (Grand Forks, ND), about 76 miles south. 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 St. Thomas	View
KMVX Grand Forks, ND	76 mi south	6,300 ft	Fair — the beam can pass over shallow snow and low-level rotation
KMBX Minot AFB, ND	157 mi west	19,600 ft	Limited — the beam overshoots the lowest part of storms
KBIS Bismarck, ND	200 mi southwest	29,200 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.
