Which radars cover Acton?

The closest NEXRAD Doppler radar is KEYX (Edwards AFB, CA), about 55 miles 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 Acton	View
KEYX Edwards AFB, CA	55 mi northeast	4,000 ft	Good — most storms and steady rain or snow show clearly
KSOX Santa Ana Mountains, CA	56 mi southeast	4,200 ft	Good — most storms and steady rain or snow show clearly
KVTX Los Angeles, CA	57 mi west	4,300 ft	Good — most storms and steady rain or snow show clearly

Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
