Which radars cover Sunol?

The closest NEXRAD Doppler radar is KMUX (San Francisco, CA), about 30 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 Sunol	View
KMUX San Francisco, CA	30 mi south	1,800 ft	Excellent — the lowest scan sees close to the ground
KDAX Sacramento, CA	64 mi north	5,000 ft	Good — most storms and steady rain or snow show clearly
KBBX Beale AFB, CA	133 mi north	14,900 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.
