Which radars cover Acton?

The closest NEXRAD Doppler radar is KBLX (Billings, MT), about 6 miles south-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 Acton	View
KBLX Billings, MT	6 mi south-southeast	300 ft	Excellent — the lowest scan sees close to the ground
KTFX Great Falls, MT	166 mi northwest	21,500 ft	Limited — the beam overshoots the lowest part of storms
KGGW Glasgow, MT	185 mi north-northeast	25,600 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.
