Which radars cover Greycliff?

The closest NEXRAD Doppler radar is KBLX (Billings, MT), about 57 miles east. 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 Greycliff	View
KBLX Billings, MT	57 mi east	4,200 ft	Good — most storms and steady rain or snow show clearly
KTFX Great Falls, MT	140 mi north-northwest	16,300 ft	Limited — the beam overshoots the lowest part of storms
KRIW Riverton, WY	197 mi south-southeast	28,500 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.
