Which radars cover Danville?

The closest NEXRAD Doppler radar is KMUX (San Francisco, CA), about 46 miles south. 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 Danville	View
KMUX San Francisco, CA	46 mi south	3,100 ft	Good — most storms and steady rain or snow show clearly
KDAX Sacramento, CA	50 mi north-northeast	3,600 ft	Good — most storms and steady rain or snow show clearly
KBBX Beale AFB, CA	118 mi north	12,400 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.
