Which radars cover Grant?

The closest NEXRAD Doppler radar is KOAX (Omaha, NE), about 73 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 Grant	View
KOAX Omaha, NE	73 mi west	6,000 ft	Fair — the beam can pass over shallow snow and low-level rotation
KDMX Des Moines, IA	77 mi east-northeast	6,500 ft	Fair — the beam can pass over shallow snow and low-level rotation
KTWX Topeka, KS	162 mi south-southwest	20,700 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.
