Which radars cover Rockvale?

The closest NEXRAD Doppler radar is KBLX (Billings, MT), about 26 miles north-northeast. 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 Rockvale	View
KBLX Billings, MT	26 mi north-northeast	1,600 ft	Excellent — the lowest scan sees close to the ground
KRIW Riverton, WY	171 mi south	22,400 ft	Limited — the beam overshoots the lowest part of storms
KTFX Great Falls, MT	180 mi northwest	24,400 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.
